Single Channel vs Dual Channel Memory - Laptop Gaming and CPU Benchmarks

959 ratings | 41164 views
You may have heard that games and applications perform better with dual channel memory compared to single channel memory, but why is this the case, and how much of an improvement can you expect? In this comparison I’ve benchmarked 16 different games in a laptop at all setting levels as well as 9 different CPU benchmarks to show you the differences in performance and help you decide if you should buy or upgrade to dual channel memory in your laptop. Check the full review of the P950EP that I was testing with in the video here: https://www.youtube.com/watch?v=dIHCiEd7GE8 Update: I forgot to note that all memory was CL17-17-17-39 ► Subscribe for weekly tech videos! https://www.youtube.com/JarrodsTech?sub_confirmation=1 My camera gear: Panasonic GH5: http://amzn.to/2DRh2K7 Sigma 18-35mm F1.8 Lens: http://amzn.to/2DQHe7I Metabones Speedbooster: http://amzn.to/2mSDCtK Davis & Sanford Tripod: http://amzn.to/2FXkC6c Rode Videomic Pro: http://amzn.to/2FUDOBH --- Follow me --- Twitter - http://www.twitter.com/JarrodsTech Facebook: https://www.facebook.com/jarrodstech We are a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for us to earn fees by linking to Amazon.com and affiliated sites.

This video was freaking brilliant!! Amazing how much of a difference this makes. I only today realised I had my desktop PC's RAM put in single channel on my motherboard. Changed it to dual channel and now very excited to get a performance boost in my games (I don't like playing at max settings and low frames, so medium to high settings are what I use).
Jarrod'sTech (2 days ago)
Thanks! Yeah it's pretty crazy how much it affects results. Good to hear the upgrade helped!

Which brand of Ram did you get? Cuz i want to take 2 sticks
Jarrod'sTech (3 days ago)
Nice!
Deathcall 666 (6 days ago)
Nice , I didn't knew the difference can be that big. Especially the 1% is huge in slot of games.
Deathcall 666 (5 days ago)
+Jarrod'sTechI forgot how important it is. I think I've seen hundreds of not thousands of benchmarks but all have dual channel test beds by default and I took it for granted.
Jarrod'sTech (6 days ago)
Yeah dual channel can help reduce stuttering a fair bit I've found due to the 1% low improvements.
Someone do a Dual Channel (Two Rams) Single Rank vs Single Channel (One Ram) Dual Rank video already
Jarrod'sTech (16 days ago)
I will if I ever have that memory available for testing.
Shivansh Khatri (16 days ago)
Can I make a single channel ram laptop (OMEN by HP 15-dc1006tx) with 1x16 GB dual channel by adding a 8GB stick ?
Jarrod'sTech (16 days ago)
I don't think so, I think they need to both be the same size.
Rodrigo Mendes (19 days ago)
Wow! I couldnt even think on that difference. I'm wondering about DDR3 too. I have friends that have DDR3 systems with 8GB in Single Channel Mode. That's a huge surprise!
Jarrod'sTech (19 days ago)
Yeah took me by surprise when I first saw it, and now I just wonder why so many y companies try to save the cost of two sticks of memory by using one when they could make their product look / perform so much better for a tiny bit extra. I haven't done the testing with DDR3 myself so I can't comment on the difference there.

Bro please tell me fast which is better 8gbx1 ram at 3000mhz or 4gbx2 at 2400mhz with these ryzen 2400g
Jarrod'sTech (1 month ago)
I haven't done that comparison, but I suspect the benefits of dual channel will outweigh the speed, plus you could still try a higher XMP profile on the DDR4-2400 memory to maybe get it higher.
Peter Mark (1 month ago)
Hi, so I have a Dell G3 with an i5-8300h and a GTX 1050 4gb and I was wondering if there would be an improvement from going from 1x8 gb 2666 mhz to 2x4 gb 2400 mhz. Thanks! Oh and I also usually only play Fortnite on all low settings.
Jarrod'sTech (1 month ago)
Yeah that should help, despite the lower memory speed I think you'll see a larger boost going to dual channel, especially with lower settings as Fortnite seems to be more CPU bound.
KING0SISQO (1 month ago)
Hmm 😑 So while it’s definitely worth having dual channel. Your unlikely going to get the full advantage of gains if you have a high end machine on ultra. But if you got a weaker gpu forcing you to use medium or below then dual channel will definitely benefit. In this case I’d say if you got a top end machine and going dual channel. Try to go for the “fastest” ram. It’s been proven that faster ram gives gains so that’s my focus now.
Chiriac Puiu (12 days ago)
you will see the difference a lot more in high end systems as you are even more likely to be limited by the memory bandwidth than some other component. and even if the average FPS doesn't change much, you'll see a big difference in the 1% lows.
Jarrod'sTech (1 month ago)
I think we see more of a difference at lower settings because they're less GPU bound, and going from single to dual channel mostly affects CPU performance
Pratham Dave (1 month ago)
Hey bro,I need some help. I'm running a i3-4130 ( dual core hylerthreaded @3.4ghz) and GTX 750ti I have 8gb DDR3 1600mhz,if I add another stick,will the performance boost will be more,less or roughly equivalent to what you've benchmarked. Love your content.Keep it up👍👌
Jarrod'sTech (1 month ago)
Thanks! Hmm, maybe a bit less but I'd still expect an improvement. I think dual channel helps more once you have good CPU/GPU, at the point where the memory starts becoming a bottleneck.
Ysarc (1 month ago)
My motherboard supports dual channel. Right now i have 8gb of RAM DDR4, a friend told me i should have put 4+4 instead of 8 but i made the argument that i will just add 8 more in the future and take advantage of the dual channel support and ill have more free slots for future ram additions. I wasn't wrong in my line of thinking was i?.
Jarrod'sTech (1 month ago)
That's fine, it just means you have single channel until you upgrade, whereas with 4+4 you could have the benefits of dual channel now. Personally I'd have done what you're doing, 16gb is a good amount and having that in dual channel would be the best option, and if it currently works fine for you then no reason to upgrade straight away.

Jarrod'sTech id honestly like to see a GS75 2080maxq with 16GB dual channel vs the GE75 2080 with the single channel memory because both of these come standard with 1x16 stick unless you upgrade it from HIDevolution
Jarrod'sTech (1 month ago)
Yeah it's a fair difference, as long as you don't have a GPU bottleneck I suppose.

PowerFromWithin (1 month ago)
Thank you so much for this video man!!! I had a single 16gb stick and added one more single 8gb stick from a compatible brand and my fps in benchmark for CPU limited games (Far Cry Primal and Rise of The Tomb Raider) went up by around 8-10 fps!! You would probably get even more gains with another 16gb stick (instead of the unmatching size 8gb), but it's pretty pricey and I'm happy with the performance boost!!
Jarrod'sTech (1 month ago)
Good to hear you were able to boost performance!
MOHAN SASI (1 month ago)
i have two doubts bro. 1.can we mix one 4gb stick with another 8gb stick to make 12gb ram. 2.can we mix one ram with single channel and other with dual channel in the same pc.
MOHAN SASI (1 month ago)
+Jarrod'sTech thank u for responding bro but i sawinthe amazon that there are sticks themselves single and double channel see the links below please double channel:Alketron™ DDR3 RAM for Laptop 4GB 1600MHz SODIMM Dual Channel CL11 (100% Tested - with 3 Years Warranty) https://www.amazon.in/dp/B07MTPRKKP/ref=cm_sw_r_cp_apa_i_MBYtCb0ZGMSCM and you know the single channel one( its common one) please clear my doubt bro.
Jarrod'sTech (1 month ago)
Yes you can use different sizes, but no they will not run in dual channel. The sticks themselves are not single or dual channel, that's something that happens based on the speed/size of the sticks. If you have two or more of the same size/speed memory you can run in dual channel.
Realme C1 (2 months ago)
What would have happen if somehow we used 4x4 gb quad channel?
Jarrod'sTech (2 months ago)
The platform itself doesn't support quad channel, some laptops have 4x memory slots but it's still dual channel. At the moment only enthusiast platforms like TR4 make use of quad channel memory.
Aarish Rahman (2 months ago)
Should i first get a ssd upgrade or ram
Aarish Rahman (2 months ago)
+Jarrod'sTech i have 8gb single channel
Jarrod'sTech (2 months ago)
What memory do you currently have? If it's 8gb or single channel, more would help in games in terms of frame rate. SSD on the other hand will just make load time faster, though in terms of quality of life I find it nearly impossible to use a HDD only machine these days, the difference is night and day in terms of load times, but the SSD won't change game FPS.
RAm Glacier (2 months ago)
Hmm I am not implying anything but this is one of the few videos where ram does substantially increase fps so makes me think it might be a platform thing..usually fps gains are seen only in 120hz panels because cpu usage but 60hz wow..I am uograding ram after this video really do hope I will see the 5fps gains it is exactly what I need to kick the ultra settings above 60fps..
Jarrod'sTech (2 months ago)
All good I didn't take it that way 😃 hope the upgrade goes well!
RAm Glacier (2 months ago)
+Jarrod'sTech oh God I am not implying you are lying I am saying this seems too good to be true! What I meant by 120hz panels is tests show that if ram to cpu becomes bottleneck at higher fps. 60fps usually do not show this kinf of boost..usually under 1% margijn of error. But hey this seems great thank you for these tests will be much easier justify the cost of upgrading my ram now..
Jarrod'sTech (2 months ago)
The refresh rate of the panel doesn't affect the frame rate the system is able to produce. If you're after another example, I upgraded my Aero 15x from single to dual channel memory in this video, I show the performance before and after in 3 games: https://youtu.be/e7xqKYxC06E?t=519
Ian Van Cauwenberg (2 months ago)
Is the performance difference the same for lower end CPUs (that get fully utilised in demanding games), like the older i5s, newer i3s or Ryzen 3. I assume (correct me if I'm wrong) that single channel has lower performance, because it fails to feed the CPU enough information, causing cores and or threads to sit idle or only partialy utilised. It seems logical (atleast to me) that if the CPU is slower, the single channel memory doesn't fall as much behind, and the performance gap would shrink. Or would it be the same? (Assuming the GPU is fully utilised) Asking, because I have a prev gen i5 and single channel memory (8gb) and I want to know if it is worth upgrading, just for dual channel. Edit: GPU is a 1050ti
Jarrod'sTech (2 months ago)
No problem! Yeah I'm waiting for it too so I can test it out and compare it with other stuff 😃
Ian Van Cauwenberg (2 months ago)
+Jarrod'sTech Thanks for the reply! (I didn't expect a response this soon on an old video.) I'm waiting on any reveals on the Navi architecture, before doing any actual upgrades. I whish I had bought the RX570 instead. (Same price better performance, although it was 50% inflated thanks to miners back then) The 1050ti won't last much longer than this year. (Although it's doing fine at the moment, considering the price).
Jarrod'sTech (2 months ago)
I haven't tested, but yes I think if you have lower graphics you may see more improvements from going to dual channel, however at the same time with lower end graphics in most cases you'd see much more improvements upgrading graphics instead. I've also heard that upgrading memory is generally done once you've already got high end graphics as that's the point where memory starts being an issue, but again I haven't done testing with low or high end options, just what I used here
Brandon Cole (2 months ago)
When GPU bound, dual-channel versus single-channel memory isn't as significant of importance versus when CPU-bound. Good video!
Jarrod'sTech (2 months ago)
Yeah, thanks!
Dante (2 months ago)
Thank you! I have been telling my friends for 2 years and they still did not believe me that Dual Channel helps in every configuration, i was telling them to get 2X 8GB instead of 1X 16GB ... I saw huge improvements in PUBG the suttering is non existent anymore and i don't get any fps dips anymore, it helped with avg. fps in every game that i play, i get a lot more fps now and there is no more stuttering and there are no more fps dips.

My laptop currently has a 4gb 2666 stick in it while the second is slot empty. Is it okay to insert a 16gb 2666 stick on the second slot? I'm a bit worried about the compatibility issues I've read online.w
Jarrod'sTech (2 months ago)
Yes, it should work as long as it supports the same speed/timings as the original stick, but I don't think it will run in dual channel unless it's the same size.

What if i have 1x 16gb ram ? Should i sell it and get 2x 8gb or buy another 16gb?
VeNoMxCoBrA (2 months ago)
Jarrod'sTech alright thanks 👍🏼
Jarrod'sTech (2 months ago)
Either option will see improved performance, as long as the second 16gb stick can run at the same speed/timings. 16gb is still enough for most games, but to be honest it might be cheaper for you to just buy a new 16gb stick right now, because if you buy 2x 8gb it will usually cost more than 1x 16gb, plus you'd have to work out selling your current 16gb stick.
Ultima X Sage (2 months ago)
By any chance, does dual channel help with thermals on a laptop?
Jarrod'sTech (2 months ago)
It makes no difference. Technically the extra stick of memory will use power and generate a very small amount of heat, but that will not affect anything practically.
ThatGingerGamer (2 months ago)
I recently built an i5 9600k PC on my channel and I used just a 16gb single stick of DDR4. The slots can use 16gb each so I planned to fill them slowly. I didn't realise a single channel config would hurt performance so much, I researched this and after Gamers Nexus video I thought the difference was within margin of error. Ill pick up another matching stick, the small gains from dual channel and the small gains for more ram should make a difference.
Jarrod'sTech (2 months ago)
I think it will help, but yeah I've seen the video you're referring to, it might make less of a difference depending on the specs though, I think if you have good specs in terms of CPU and GPU then it's worthwhile as a next step upgrade.
Bao Pico (2 months ago)
Let say 1x8GB 2400Mhz sodimm, Is there any physical difference between single rank and dual rank?
Jarrod'sTech (2 months ago)
Yes that's right, it will look difference in appearance.
Bao Pico (2 months ago)
+Jarrod'sTech I mean the appearance, dual rank has more chip than single. But seem like the 1x16GB only available in dual rank.
Jarrod'sTech (2 months ago)
What do you mean by physical? The sticks should physically look different? I've never done any testing with single / dual rank in any case.
Demaniax Chinmay (2 months ago)
Can I run a 8GB and a 4GB in dual channel or they have to be of the same size ?
Jarrod'sTech (2 months ago)
Worth researching further, but I'm pretty sure they need to be the same size.
Demaniax Chinmay (2 months ago)
+Jarrod'sTech Actually I'm full of curiosity. With Sky high DDR4 prices, if the memory bandwidth can be doubled using the 8+4 config that would be best of both worlds as 16GB is not needed yet for games, 12GB is the sweet spot.
Jarrod'sTech (2 months ago)
I believe they need to be the same size, but have not tested.
vikas l (3 months ago)
hey jarrod i have astric scar 2 gtx 1060 model, the laptop came with single channel. I have gpu utilisation problems and fps dips every 5 or 10 seconds, its like a game would run 50-60fps constant and then drops suddenly to 5fps. i had reset my pc, scanned for all malwares and viruses and fixed all of them and still the problem exists . Do you think its cause of single channel memory or its a problem with manufacturing. i really love this laptop and i hate to have this problem when everything is perfect. Oh and i looked this issue up online and i found around 5 more having the same issue and with the 1060 model and no solution yet. the power adapter is 180W(for 1060). Can please help me out here, if its single channel memory issue or something else.
Jarrod'sTech (3 months ago)
Dual channel could help, the only other time I've seen that happen was when the power brick the laptop had wasn't enough to power the hardware, so it would keep swapping to battery power (this was obvious though because the FPS dipped to 30 FPS as per Nvidia battery boost and the screen would dim like it was on battery power), so the solution there was to get a bigger power brick.
vikas l (3 months ago)
uAnd as seen in the video, the fps does improve much when graphics settings are lowered and especially in ac origins i had to play the whole game in lower fps as i wondered whats wrong i got a 1060 in here
Karl Manson (3 months ago)
for me beside better fps, the stability is better in dual channel, when im playing rise of tomb rider use 1x8 gb the framerate is up and down, from 50 suddenly drop to 30, when im playing in dual channel, the fps stabile between 45-50, and rarely hit 30 fps.
Jarrod'sTech (3 months ago)
Yeah higher frame times from dual channel memory helps with that 👍
kumar kn (3 months ago)

Jarrod'sTech (3 months ago)
You mean with 4gb and 8gb together? It will increase the overall available space but I don't think it will run in dual channel
Yassier Bhai (3 months ago)
I have 4gb ram.. And i want add another 8gb RAm to my laptop to make it 12gb Ram in total. It is good or bad ? Pls answer my question.. Bcause some people says it is better to put same stick like 4x2 and 8x2 ... Someone pls answer. Thanks. Sorry for my bad english
Jarrod'sTech (3 months ago)
It's good if you need more space, but it won't run in dual channel because they're different sizes. 2x 4gb will be better for performance, but less overall space. 2x 8gb if you can afford it would be the best upgrade, you get the best of both more space and dual channel memory (also worth noting if you get another 4gb stick, for dual channel it needs to run the same speed / timings / size).
mars on bass (3 months ago)
when you are gaming in single stick ram is there any frames fluctuation? i ask same question in the other review but for 1 year now im not getting any replies. :(
Jarrod'sTech (3 months ago)
+mars on bass No problem! Yeah most people don't make time to reply to all comments like me, but then again maybe their channels are just too big to manage it!
mars on bass (3 months ago)
+Jarrod'sTech i asked the same question to other utuber. im not getting any reply. Thank u Jarrod
Jarrod'sTech (3 months ago)
Did you reply to someone elses old comment? If so I will probably never see it, if you leave a new fresh comment I will always reply to it. Yes, that's what this video shows, 2x sticks in dual channel is faster than 1x stick in single channel. With single stick you'll get lower frame time performance, so there will be more dips, as shown by the lower 1% lows in the graphs.
john campos (3 months ago)
Hello Jarrod, it's me again. Hehehe. Now for ram since this video is about single vs dual channel. Dual channel rams here in my country are much expensive than the single channel rams. I'm planning to buy 16gb ram. There was 2 diff 16gb ram that I'm choosing. There is a 16gb single channel ram 3000mhz for like $107 (on sale) and there is the other one 8x2 2666mhz for $130 (the cheapest dual channel 16gb ram and w/ RGB). What is your recommendation for a pc build that is for gaming, streaming and editing (adobe software)?
Jarrod'sTech (3 months ago)
Sounds good!
john campos (3 months ago)
+Jarrod'sTech I'm buying r5 2600 for cpu and rx 590 for my gpu.
john campos (3 months ago)
+Jarrod'sTech well here in my country, the currency of that $23 is huge. But if it's for more speed, I think I'll go for dual channel.
Jarrod'sTech (3 months ago)
I think it's worth going the extra $23 to get 2x sticks of memory to run in dual channel, the performance boost for that small amount of money seems worth it to me, but if you can upgrade your CPU/graphics instead for that money that would likely give you better improvements.

I just bought an Omen 15 and it has a single 16GB stick and it's pretty mediocre 2666MHz @ CL19, bummer! Now I pretty much have to sell the stick and get a 2x8 kit like Vengeance or Ripjaws. Do you have any idea on what the max. RAM speed is for a 8750H Omen?
Martin M (3 months ago)
+Jarrod'sTech Agreed, 2666 seems to be the fastest I've encountered even in gaming laptops.
Jarrod'sTech (3 months ago)
Hmm I don't know much about that, I know the CPU officially supports DDR4-2666, but I almost never see any laptops with higher RAM speeds, I know it is possible but some people seem to be saying it's more trouble than it's worth.
lol nah (3 months ago)
So, lower the settings, bigger the difference
Jarrod'sTech (3 months ago)
Yeah lower settings are more CPU bound, whereas higher settings usually rely more on the GPU.

Great video. Thank you. Do you think 2x8gb 2400 would still be better than 1x16gb 2666?
Jarrod'sTech (3 months ago)
Cheers! Hmmm, I think it would be based on what I suspect, but I also haven't done any testing to confirm. I think the difference between DDR4-2400 and 2666 is less so compared to single vs dual channel, but just a suspicion.
free styla (3 months ago)
hey jarrod good video ! should i sell my 16gb ram to get 2×8gb ram ? or just picking another 16gb ram on it ? would it make any differnce if i have 2×8 or 2×16 ram ? i know its better than single i just wanna ask xD thanks
Jarrod'sTech (3 months ago)
Thanks! Hmm probably depends more on whether you need 16gb total or 32gb. My current laptop has a single 16gb stick, I'm selling it for 2x 16gb sticks but that's because I want both dual channel and a lot of space for video editing.
Colby Boucher (3 months ago)
I thought 2 8gb DIMMs in dual-channel would still be 8gb just faster?
Jarrod'sTech (3 months ago)
No, there would still be 16gb of total space available with 2x 8gb sticks.
Sawyer Bass (3 months ago)
I feel bad. I've been using my desktop with single channel memory for a while and I never actually bothered to wonder if the reason my R7 1700 felt worse than my 4790K did was the memory until a few months into using it. Worst thing is since I use Linux half of the time, and the video drivers there are a bit more CPU bound, it's been killing me. Kinda resent spending more than I did two years ago on 8GB DDR3 to get one more 4GB stick though.
Jarrod'sTech (3 months ago)
Definitely worth considering the second stick as a future upgrade!

CPY (3 months ago)
Like SLI for RAM! :D
Thelango99 (3 months ago)
Current SLI technology alternates between which cards render what frame at what time. This means that in SLI the two (or more) GPU's never work together to render a single frame, as this is the issue that DX12 Mgpu effectively solves.
Thelango99 (3 months ago)
Not quite. This is because the CPU can access both channels of ram at the same time, so it is less like SLI and more like RAID 0.
Jarrod'sTech (3 months ago)
Haha yeah I guess that's one way of thinking about it 😁
Andrei Zota (3 months ago)
Hi! I have one RAM stick running at 2666MHZ and I want to know if it would help for gaming if I buy another exact stick to run in dual channel. Will the performance gain be the same as the 16GB in dual channel or lower? Does it worth the investment?
Jarrod'sTech (3 months ago)
No problem at all!
Andrei Zota (3 months ago)
Thanks for the help! :)
Jarrod'sTech (3 months ago)
Yes, but you would see benefit from dual channel which may be worth it.
Andrei Zota (3 months ago)
For gaming only, 32GB would it be overkill?
Jarrod'sTech (3 months ago)
Oh didn't realize you already had a single stick of 16GB, sorry! In that case yeah you could buy another 16GB stick for dual channel, but might be expensive. If price is an issue, maybe you could sell the 1x 16GB stick and buy 2x 8GB sticks instead both options work just depends on budget and whether you think you'd use more than 16GB of memory in total.

Hi, very nice video! Another important thing in the RAM is the CL, in the laptos is not good as well. I would to buy a new RAM stick for my MSI GE63 ([email protected]) but I am indeterminated to pickup 2 new with a better CL(a lot of money for the ) or only a new one with the same (actualy CL17)... What CL uses the laptop of the review ? I need to take a decision :)
Jarrod'sTech (3 months ago)
Thanks! At DDR4-2400 the timings were 17-17-17-39 with both, yeah it can affect results too, I used the same here and didn't look into adjusting timings but would like to also investigate that in the future 👍

1:50 "all we're changing is single to dual channel" Lies. You used different sticks with a different number of slots. That completely invalidates everything.
Chiriac Puiu (12 days ago)
@usucdik are you retarded or just looking for your 5 minutes of fame? this is the normal way of testing the performance gains from using 2 sticks in dual channel vs 1 stick while keeping the same capacity and speeds. it is the most relevant test especially for laptop owners which often come with just 1 stick of memory and they don't know if they should buy another similar RAM stick or replace it with a bigger one. what is your problem? you are not making any sense at all with your arguments. FYI yes you can test HT vs non HT while using a those 2 CPUs. all you have to do is manually set the clock speeds to be the same same so that it doesn't become a variable in your tests. percentages taken from multiple tests don't just suddenly change like you imagine them to.
usucdik (3 months ago)
+Jarrod'sTech All you did was post two separate benchmarks that don't really have anything to do with each other. Great work here, dude. I await your next video "Hyperthreading vs. Non-Hyperthreading - Benchmarks" where you swap out a 9900k with a 9700k and note the difference.
Jarrod'sTech (3 months ago)
I'm waiting for you to clarify on what specifically is invalid, if it's because I should have run single channel with the 2x sticks, well I admit when I did the testing I didn't know that was a thing, but I still have my doubts it would contribute much compared to what I've done here, which I feel represents the commonly asked question of "should I use 1 larger stick or 2 smaller ones", seems pretty valid to me.
usucdik (3 months ago)
+Jarrod'sTech Still invalid, but thanks for the rhetoric.
Jarrod'sTech (3 months ago)
What are you talking about? The exact same laptop was used, it only has 2 slots. Yes, single channel only used one slot, and dual channel used two slots, that's the most common configuration of how single and dual channel work lol. Unless you're saying I should run two sticks in single channel? Either way it was as apples to apples as I could make it with the hardware available to me and I stand by the results.
I never know it will be this much gain, thanks for the insight. Btw how about 2400mhz vs 2666mhz ? Is there noticeable perf difference ?
Jarrod'sTech (3 months ago)
I haven't tested in a laptop so results may be different, but I've tested different memory speeds here: https://youtu.be/PR68C2bUgFI

Julian Pollak (3 months ago)
Didn't even realise, I had only one 16GB stick in my laptop. Guess what happened when I added a second one (matching everything)?? ... 35% more performance across many games, similar to this video!
Chiriac Puiu (13 days ago)
+Lamss going from 16 to 32 won't net you more than 1-2% perf in the majority of games. most of it comes from going from single to dual channel as you are bandwidth limited not capacity limited.
Lamss (1 month ago)
Because you went to 32GB?
Jarrod'sTech (3 months ago)
Nice boost!
RODRIGO FILHO (3 months ago)
That 1% tho, time to get one 16GB stick for my Helios 300... I hate that Acer sold the notebook with one 16GB stick.
Jarrod'sTech (3 months ago)
Hmm I believe for dual channel you want same size/speed/timings for it to run in dual channel, otherwise may run in single channel. I had a similar issue recently, I just bought a fresh 2x stick kit and going to sell my original 1 stick.
RODRIGO FILHO (3 months ago)
+Jarrod'sTech I'm thinking about getting 1 16GB CL14 module, and see how it runs with the stock stick. I hope that the stock stick can keep up to the one i will buy.
Jarrod'sTech (3 months ago)
Yeah it definitely makes a bigger difference there, I just bought a 2x stick kit for my own laptop, going to upgrade it in a future video and see how it helps!
Desi Car Guy PK (3 months ago)
In the Dell G7 i was trying to find comparison for the options 4*2 GB RAM vs Single stick 16GB so which is faster ? I have 4*2 GB RAM config
Jarrod'sTech (3 months ago)
I would expect the dual channel you've got to be faster, but if you are using all the space the alternative is swapping over to disk which is a very slow process and will probably be worse.

Jarrod'sTech (3 months ago)
Yes one in every hundred or so comments complains about this, honestly there's not much I can do, not sure if it's just part of the Australian accent but I've tried changing it and people still mention it lol, so I figured I'd just talk normally for me and let random strangers on the Internet deal with it 😉

Yeah, try to match speed/timings/size and you should be ok, maybe even voltage too if possible.
Giedrius Brūžas (4 months ago)
1:07 paired ram sticks show somewhat improvement in performance.

Ernest Marvin Esteban (4 months ago)
So I now I have an single 8Gb Hyper X Ram. Do I just buy another one of the same to make it dual channel?
Jarrod'sTech (4 months ago)
There's no differences with the memory sticks themselves, it makes no difference - dual channel is just the act of running two sticks or more together, it's a platform feature rather than part of the physical memory stick.
Ernest Marvin Esteban (4 months ago)
+Jarrod'sTech Okay then you so much for the fast reply!. I'm just a little confused because I also saw a youtuber saying Dual Channel memory is different from Single channel memory. I'm about to buy another one and I'm afraid that buying a single stick again will be a waste of money if what I'm after is to have dual channel.
Jarrod'sTech (4 months ago)
Basically yeah, try to get the same model ideally, otherwise at least make sure the sticks are the same size/speed/timings/voltage.

How big is the difference between 8GB and 16GB in modern games? I'm considering buying 8GB version and upgrading ram later one since the ram prices are slowly going down

I thought I might have to buy another stick for my laptop thats processor is a little bit outdated : i5-7300HQ. But gpu is a 1060 3gb. I bought my laptop about 10 months ago and it was just going off the market i was buying it from. So if i upgrade it to 2 channel, from 8 to 16gb. I dont necessarily need to upgrade the processor just yet...?
Jarrod'sTech (4 months ago)
Only if it uses MXM, which you only really see in really large laptops, for the most part they're soldered to the board too.
Big Chungus (4 months ago)
+Jarrod'sTech Im not new neither am I old on computers, but if necessary the gpu is still replacable?
Jarrod'sTech (4 months ago)
Yeah going to dual channel should help. You can't upgrade the CPU anyway as it's soldered to the board, unless you buy a whole new laptop, dual channel memory is a good first move.
Jose Valdes (4 months ago)
With 1060 3gb max-q will I have better performance? , I want to increase another 8gb of ram to my laptop to have 16gb... my lap 7700hq 8gb ram 2400 1060 max q
Jarrod'sTech (4 months ago)
Yeah I think you'll see an improvement with dual channel there.
Jg (4 months ago)
Any idea if the Ram size should be the same? My gm501 has 16gb single channel and i was going to add another 8gb, would that okay or would i need 16gb to see the best increase?

No problem!
Jg (4 months ago)
Jarrod'sTech Cheers for the info, appreciated
Jarrod'sTech (4 months ago)
Yeah that would be ideal. I recently got a new laptop, I couldn't find the same 16gb stick it had, so I just bought a new set with 2x sticks and I will sell the original stick that came with it.
Jg (4 months ago)
+Jarrod'sTech Thanks, any idea if the same brand matters aswell? So would getting 2x16 gb Crucial RAM be better than 1 stick and using the one already in my laptop?
Jarrod'sTech (4 months ago)
Yeah they need to be the same size, ideally same timings and speed too - as close to the same as possible.

Hi sir, I wanted to ask you whether there will be an increment in performance if I install an 8 GB RAM in a laptop which has come with a single stick of 16 GB RAM ??? PLEASE REPLY 🙏🏼🙏🏼🙏🏼 It has 4 slots by the way ...
Anvith M Kunder (3 months ago)
+Jarrod'sTech Hi sir , I've removed the 16gb stick and have installed 2 8gb sticks in my asus scar 2 gl504gm ( the one with gtx 1060 ) but the frequency doesn't seem to go above 2400Mhz , there isn't a setting in the BIOS for xmp . Can you please instruct me what to do 🙏🏼🙏🏼🙏🏼... And also there is not that much increment in the performance also... Any Idea what may be the cause , is it the frequency ???
Anvith M Kunder (4 months ago)
+Jarrod'sTech Thank you so much 👍🏼👍🏼👍🏼
Jarrod'sTech (4 months ago)
I think that will still be in single channel, you'll just get more total memory size to use. You could try, but I suspect if you take out the 16gb stick and just use the 2x 8gb in dual channel you'll see faster performance. If that works fine you could then just sell the 16gb stick.
Anvith M Kunder (4 months ago)
+Jarrod'sTech If I put 2 similar sticks of 8 GB RAMS with the 16 GB single stick provided by the manufacturer , will there be difference ?
Jarrod'sTech (4 months ago)
Unfortunately not, the memory would need to be the same size/speed/voltage etc for dual channel to work I believe. Ideally you want two of the same sticks.

Great topic, Jarrod :) Since I have AN5 7300hq GTX 1050Ti 8GB(Adata) 2133 MHz. Really planning to add Patriot Viper 16GB (2*8gb) 2400Mhz Cl15. Any advice which is better value?
Jarrod'sTech (4 months ago)
Thanks! To be honest I'm not too familiar with the different memory modules, I recently bought a G.Skill Ripjaws kit but that was just because my laptop (Aero 15x) has pretty limited memory module support, only 4 different types officially listed so wasn't much choice for me, my recommendation would be to confirm that what you plan on buying is supported just to be sure.

I've literally spent the last year of playing Overwatch constantly getting annoyed due to inexplicably low framerates, after trying every single solution I could find online. This video finally explains it. Thank you for this, more people should be aware of the difference dual channel memory makes.

Ingeborg Svensson (5 months ago)
Great video thanks. There is a lot of misinformation out there. I have a dual channel board and only two of the four slots are currently populated in dual channel configuration. So if I want to upgrade later I would only need to buy two more memory sticks of the same capacity and speed as the other two, is that correct?
Ingeborg Svensson (5 months ago)
+Jarrod'sTech Thanks Jarrod! According to Techquickie (yes Linus) and many other self proclaimed 'experts' on Youtube you would have to buy a quad channel kit for dual channel PC and it would 'probably' work, no guarantees though. According to my local PC shop (Netherlands, Europe) there is no such thing as special memory kits for multiple channels, just buy 4 identical RAM sticks and you should be fine. And if you already have two: buy another two that are the exact same. Glad you confirmed that, I wanted to be 100% sure before buying any more RAM because it is still quite expensive. Techquickie: https://www.youtube.com/watch?v=-D8fhsXqq4o
Jarrod'sTech (5 months ago)
No problem! Yes that sounds correct, if all 4 are populated at the same size/speed all should be running in dual channel.

Does that mean metabox will ship my laptop with 2x8gb instead of a single 16gb stick if I ask?
Jarrod'sTech (5 months ago)
Yeah I think you can ask for it, I asked them why they don't list both options when customizing on their site and the answer wasn't clear, but they said you can contact them and ask for dual channel, might cost a little more though, but typically worth it.

Yeah super low end options may only have one, another reason to check the slots before buying memory I suppose, didn't consider mentioning that in the video.

Jarrod i have a question. Which is better? 16gb (single channel) or 2 8 gb (single channel) or 16gb(dual)
Jarrod'sTech (6 months ago)
16gb in dual channel would be the best out of those configurations.
Kenshinhugo (6 months ago)
Thx for the video. Building up an itx built but the 2 slots are a big handicap for me which made it 2x8 or 1x16 stick with an option to later buy just another stick or having to buy 2x16 is quite significant. I'll go for the 1x16 but what are you guys prefs
Jarrod'sTech (6 months ago)
Hmm if you really need more than 16gb I'd do the single 16gb option and upgrade later.

Jarrod'sTech (6 months ago)
Hmm probably not, don't currently have any lower specced hardware available or spare memory at the moment, and the full testing took multiple days of work to complete 😢 I'd expect the changes to be similar in percentages though
P GR (6 months ago)
This is a major increase for most laptops with integrated graphics. It's even more dramatic for them because of the graphics sharing the main memory bandwidth. You can virtually double that bandwidth just by adding an extra RAM stick to make the machine dual channel. It's a huge leap.
Jarrod'sTech (6 months ago)
Yeah I have heard that, considering doing another video but the same test on integrated graphics in future, just depends on time and if I'm able to get more memory to test with.

69aussieguy (6 months ago)
On the game tests, does the built in benchmark require as much CPU and RAM usage compared to gameplay? My thoughts are, the benchmark tests aren't the same as the normal game and probably doesn't show the true difference between single and dual channel memory.
Jarrod'sTech (6 months ago)
Many of the benchmarks are designed to closely match real game play, otherwise they serve little purpose, that said I know some are different, it really depends on the game. Either way I have still tested a number of games while actually playing them myself, mostly the ones that don't have built in benchmark tools, and we still see similar performance improvements there.
GamingKing (6 months ago)
does a single stick of 8 gb ddr4 ram run at 2100-2400 mhz? i have a msi gp62mvr leopard pro notebook, i5 7300hq, gtx 1060 3gb, 8 gb ddr4 single channel ram. the hwinfo64 program shows a maximum frequency of 1200 mhz...is this normal?
Jarrod'sTech (6 months ago)
Yes that sounds fine, 1200MHz means DDR4-2400, if you look in task manager > performance tab > memory, it should show as 2400MHz, the speed supported by the 7th generation of CPUs.
