Single Channel vs Dual Channel Memory - Gaming and CPU Benchmarks

641 ratings | 22588 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 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.

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 (9 hours 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 (18 hours 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 (10 hours 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.

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)?
john campos (9 hours ago)
+Jarrod'sTech I'm buying r5 2600 for cpu and rx 590 for my gpu.
john campos (9 hours 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 (10 hours 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.

Still cant believe this channel only has 40k subscribers.
Jarrod'sTech (1 day ago)
Getting there!
Martin M (2 days ago)
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 (2 days ago)
+Jarrod'sTech Agreed, 2666 seems to be the fastest I've encountered even in gaming laptops.
Jarrod'sTech (2 days 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.
Do Why (3 days ago)
So, lower the settings, bigger the difference
Jarrod'sTech (3 days ago)
Yeah lower settings are more CPU bound, whereas higher settings usually rely more on the GPU.
O McLachlan (4 days ago)
Great video. Thank you. Do you think 2x8gb 2400 would still be better than 1x16gb 2666?
Jarrod'sTech (4 days 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.
pokemon Discord (4 days 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 (4 days 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 (4 days ago)
I thought 2 8gb DIMMs in dual-channel would still be 8gb just faster?
Jarrod'sTech (4 days ago)
No, there would still be 16gb of total space available with 2x 8gb sticks.
Sawyer Bass (5 days 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 (5 days ago)
Definitely worth considering the second stick as a future upgrade!
Evan Devries (5 days ago)
Remember triple channel?
Jarrod'sTech (5 days ago)
+Evan Devries I don't know, I guess I focus mostly on laptop stuff on the channel and no triple channel laptops that I'm aware of 😛
Evan Devries (5 days ago)
+Jarrod'sTech Worth doing some sort of recap about it? :O
Jarrod'sTech (5 days ago)
Yeah I have a PC under my desk that uses it from 2010 😎
CPY (7 days ago)
Like SLI for RAM! :D
Thelango99 (5 days 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 (5 days 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 (7 days ago)
Haha yeah I guess that's one way of thinking about it 😁
Andrei Zota (7 days 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 (7 days ago)
No problem at all!
Andrei Zota (7 days ago)
Thanks for the help! :)
Jarrod'sTech (7 days ago)
Yes, but you would see benefit from dual channel which may be worth it.
Andrei Zota (7 days ago)
For gaming only, 32GB would it be overkill?
Jarrod'sTech (7 days 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.
Rob Haskell (7 days ago)
Are the RAM sticks even the same? You didnt even say if they had the same CL. They couldve been completely different RAM sticks. Thats a big failure.
Jarrod'sTech (7 days ago)
Notations are being removed in a few weeks :( I'll update the desc.
Rob Haskell (7 days ago)
Thats really good to hear. Youshould add a notation bubble to the video for clarity. +Jarrod'sTech
Jarrod'sTech (7 days ago)
Yes.
Rob Haskell (7 days ago)
Are you SURE that that applies to BOTH of them? +Jarrod'sTech
Jarrod'sTech (7 days ago)
Yes. CL17-17-17-39 at DDR4-2400, there you go.
Vic F093 (7 days ago)
This video really helped me, thanks a lot
Jarrod'sTech (7 days ago)
No problem at all!
Pere Comellas (7 days ago)
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 (7 days 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 👍

😁
usucdik (8 days ago)
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.
usucdik (8 days 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 (8 days 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 (8 days ago)
+Jarrod'sTech Still invalid, but thanks for the rhetoric.
Jarrod'sTech (8 days 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 (8 days 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
LAKSHMI PRASAD (11 days ago)
Thank you very much bro you saved me from wasting money 😃😊 Its better i go for dual channel😁
Jarrod'sTech (11 days ago)
No problem at all! Yeah it should help out 👍 I just bought some new memory for my personal laptop to upgrade to dual channel, going to cover the performance differences in an upcoming video 😃
Julian Pollak (14 days 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!
Jarrod'sTech (14 days ago)
Nice boost!
RODRIGO FILHO (14 days 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 (14 days 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 (14 days 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 (14 days 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!
Xtreme Gamerz (15 days 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 (15 days 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.
Wallasmod (15 days ago)
Wow thank you for this
Jarrod'sTech (15 days ago)

Jeremy (17 days ago)
Just saw this and it's a good comparison, but you need to watch your own video. Imo you overpronounce every sentence too much, as if every sentence was a title. I don't know if it's just me, but it sounds kinda bad. It's mostly the end of each sentence
Jarrod'sTech (17 days 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 😉
Sakkyokuka宝石 (20 days ago)
3:22 what do you mean by 1% lows
Jarrod'sTech (20 days ago)
It's a way of measuring the dips in performance, this video explains it: https://www.youtube.com/watch?v=l6WgbfG_z-k
Dan Dan (21 days ago)
but when trying to cool ram with heatsink will it improve performance?
Dan Dan (14 days ago)
+Jarrod'sTech by the way have you try using 2 vacuum cooler?
Jarrod'sTech (21 days ago)
I really doubt it, I've never seen memory overheating to the point where it reduces performance in any meaningful manner, at least compared to overheating on the CPU/GPU.

Can I use different brand of ram but exact specs?
Jarrod'sTech (25 days ago)
+Dan Dan No problem, welcome to the channel!
Dan Dan (25 days ago)
Thank i subbed
Jarrod'sTech (25 days ago)
Yeah, try to match speed/timings/size and you should be ok, maybe even voltage too if possible.
Giedrius Brūžas (25 days ago)
1:07 paired ram sticks show somewhat improvement in performance.
Jarrod'sTech (25 days ago)
I think as long as you're matching speed/size/timings/voltage it should be about the same.
Sebastian Japal (25 days ago)
I'm here bc dual channel memory dose any laptop turn on or project a monitor like instead of a gaming pc pls answer
Jarrod'sTech (25 days ago)
Not sure what you're asking, sorry.
Ernest Marvin Esteban (25 days 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 (25 days 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 (25 days 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 (25 days ago)
Basically yeah, try to get the same model ideally, otherwise at least make sure the sticks are the same size/speed/timings/voltage.
SentiBM (26 days ago)
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
1GTX1 (16 days ago)
+Jarrod'sTech I went from 8GB of ram (2x4) to 16GB (2x8) and noticed smother performance in many games when i move my mouse even if they are using only around 6GB of RAM. Could this be true or am i imagining xD

cantrelateexe 32gb (27 days ago)
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 (27 days 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.
cantrelateexe 32gb (27 days ago)
+Jarrod'sTech Im not new neither am I old on computers, but if necessary the gpu is still replacable?
Jarrod'sTech (27 days 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 (29 days 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 (29 days ago)
Yeah I think you'll see an improvement with dual channel there.
Jg (1 month 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?
Jarrod'sTech (1 month ago)
No problem!
Jg (1 month ago)
Jarrod'sTech Cheers for the info, appreciated
Jarrod'sTech (1 month 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 (1 month 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 (1 month ago)
Yeah they need to be the same size, ideally same timings and speed too - as close to the same as possible.

I ordered predator hellios 300 with a capacity of upto 32 gb(4 slots) but the one I buy was only using one slot with 8gb , should I upgrade ?
Jarrod'sTech (1 month ago)
Hmm I think the Helios 300 only has 2 memory slots (up to 32gb). Yeah definitely worth upgrading to dual channel if possible, as shown here it should help.

Anvith M Kunder (1 month ago)
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 (1 month ago)
+Jarrod'sTech Will there be any performance issue if I put 2×8 GB rams (of similar specs) along with the 16 GB RAM which came with the laptop ???
Anvith M Kunder (1 month ago)
+Jarrod'sTech Thank you so much 👍🏼👍🏼👍🏼
Jarrod'sTech (1 month 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 (1 month 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 (1 month 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 (1 month 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.
Maarten Oudejans (1 month ago)
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.

Nice one!

+Jarrod'sTech Upgraded today. My god, even in the most actionpacked teamfights in Overwatch my fps never dropped below 144, whereas before the upgrade it would sometimes go down to 90. Feels great to finally be able to fully enjoy the game.

Ingeborg Svensson (1 month 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 (1 month 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 (1 month ago)
No problem! Yes that sounds correct, if all 4 are populated at the same size/speed all should be running in dual channel.

Tico2858 (2 months ago)
Does that mean metabox will ship my laptop with 2x8gb instead of a single 16gb stick if I ask?
Jarrod'sTech (2 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.
ccjh0806 (2 months ago)
If i have a 16GB stick and i add a 2/4GB stick do i get dual channel improvements?
Jarrod'sTech (2 months ago)
No, I believe that both sticks need to be the same size/speed for dual channel to work.
Martin Pedersen (2 months ago)
wondering if adding dual channel to my ASUS ROG GL752VW-T4004T would be worth it... has a 960m?
Jarrod'sTech (2 months ago)
Yeah I'd still expect it to improve things, as for worth it difficult to say as I haven't tested that specific graphics card but I would still think it would give a nice little improvement.

Thankfully I was still in my limit of time to return, I purchased a Dell G5 with an 8750h for $849, have another 8g stick of ddr4 coming this week for it, thats what brought me to this video.
Jarrod'sTech (3 months ago)
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.

16gb in dual channel would be the best out of those configurations.

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 (3 months ago)
Hmm if you really need more than 16gb I'd do the single 16gb option and upgrade later.
marcelpoisl (3 months ago)
Thanks man! Could you test it with some weaker hardware? Like a gtx 1050 and a i5 7300hq? I have a laptop with those specs, I'd like to know if its worthy the upgrade!
Jarrod'sTech (3 months ago)
No problem! Let me know how it changes things, interested to hear.
marcelpoisl (3 months ago)
Thank you! I'll try this upgrade. Thanks for your time!
Jarrod'sTech (3 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

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 (3 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.

It may work, but it is not recommended, especially with the different latency, my guess would be that it probably won't work.

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 (3 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.

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 (3 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.
Mr Rithy (3 months ago)
Can I7 8750H support RAM speed 3200mhz and can it increase fps for gaming ?
Jarrod'sTech (3 months ago)
I presume so, it's a desktop CPU and would use the Z370 chipset and should be possible to use XMP profiles.
Mr Rithy (3 months ago)
how about i7 8700k intel spec note the same ?
Jarrod'sTech (3 months ago)
To be honest I'm not sure, possibly, but I've never tested it and the Intel spec sheet only notes 2666 support.

Hi my laptop has a single 16gb ddr4 2666 mhz ram. Now I want to make it dual channel. Will adding 8 GB ddr4 will do any good or I should add 16gb stick? I don't want to spend unnecessarily. I don't want to lose fps on single channel.

Transhumanist (3 months ago)
The GPU and CPU are not the only bottlenecks in computing, modern CPUs clock much faster than most consumer RAM can keep up with when storing and sorting data. Having two separate channels to draw from in parallel speeds this process up. Not as much information is being allocated, written and read in memory in the benchmarking software as they are in game applications because there are very few data structures used in them, which on the other hand is a constant task for even the simplest games on the lowest settings. That's why there is no discernible difference in 3DMark and such. The more you know! Fantastic analysis nonetheless.

Hi Jarrod, I just want to say thank you for making this video anyway i really want someone advice for my problem, right now im using dell inspiron 7577 with 16gb 1 stick ddr4 ram.. so can i run dual channel by only buy 4 or 8gb ddr4 ram only? because buying a same 16gb ram will waste a lot of my money.. also what is the best brand suitable for my inspiron 7577? hope you can help me TQVM
Andre Sinaga (3 days ago)
+Amrie47 "BUT if i buy 8gb ram ddr4 with the same manufacturer and speed (2400mhz) as what i use right now will it turn the dual channel mode? " no it doesn't, you need same speed, same size, same manufacture, same type....to make it become dual channel....if you have 16 GB stick right now, and want to get dual channel performance, the best way is either, buy another 16 GB stick, or sell you current stick, and get 2x8GB KIT RAM.... Ciao
Amrie47 (3 months ago)
+Jarrod'sTech TQ for your reply, i see.. so the only way to make dual channel work is by adding the 16gb ram only right? sadly i wont buy cause is little bit expensive compare to 8 or 4gb ram.. BUT if i buy 8gb ram ddr4 with the same manufacturer and speed (2400mhz) as what i use right now will it turn the dual channel mode? cause on my country (Malaysia) ram is so expensive especially 16gb.. anyway TQ so much for your reply i really appreciate it, 😁
Jarrod'sTech (3 months ago)
Hey, no problem! If you currently have 1 16gb stick the best thing to do would be to add in a second 16gb stick of the same size and speed, ideally from the same brand as the existing memory for best compatibility. I'm not 100%, but I THINK you need the same size memory for dual channel to work, so 16gb+4gb or 16gb+8gb will probably not work in dual channel, you'll just increase the overall size.

Thanks Jarrod! I have a laptop with a 1060 and i7-7700HQ. Popular config, so I was always wondering why it was performing worse than expected (when I compared to different benchmarks on YouTube), as there were no problems with thermals and everything was good on software side too. Well now I know why exactly. Already -downloaded more RAM- ordered a second stick, should arrive in a few days. Good luck and keep up the good work!

Thank you very much for the informative video jarrod! I own dell 7577 and It has 1x16 gb stick of RAM. When I tried playing battlefield 1 it suffers with terrible fps dips and bad performance. I heard that BF! is quite unoptimized since all other games i played managed to play smoothly with high fps above 60 no problem, while BF1 is struggling even to mantain 60 fps. I tried undervolting, game setting using script nothing works. Do you think changing my RAM to dual channel will help? I know BF1 is a cpu intensive game and since 7577 using 7700hq it could be the cause of throttling since it has Thermal Power limit, but I want to know what is your opinion on this. What is the best dual channel SODIMM RAM for laptop without breaking the bank in Australia? I want your opinion? It's very pricey right now as I can see. Thanks!
Jarrod'sTech (4 months ago)
Oh that's interesting, from my experience BF1 generally runs quite well, although I only test campaign and not multiplayer so that might be the difference. You could try running Intel XTU, it will visibly show you if you hit CPU power limit or thermal throttling, just run BF1 in a window next to it for 10 mins or so and watch what XTU says, but yeah I think in general dual channel memory should improve things a bit. To be honest I'm not sure about SODIMM memory so much, there doesn't seem to be that many options for it in Australia, a few kids on pccasegear but the 2666MHz stuff seems quite limited and insanely expensive.
Tom T (4 months ago)
Great video, Jarrod! Like many others I didn't expect quite that big of a performance difference in games using a discrete video card. We've done a lot of low end gaming here using various NUCs and with Integrated Video, dual channel low latency memory is a requirement. When you're running low end, you need every frame you can squeeze out. Nice to know that it also makes a big difference in the upmarket gaming world! Fantastic effort, clear, concise, I love your channel. More subs people!
Jarrod'sTech (4 months ago)
Thanks Tom! Yeah I've heard that about integrated graphics but haven't had a chance to test it myself yet, maybe worth benchmarking in a future video!

Jarrod'sTech (4 months ago)
Yeah the Zephyrus gets pretty warm, I would have hoped it wasn't quite as hot with the 1060 as I only tested the 1070 model, but I guess that's not the case :(

Jarrod'sTech like u said sometimes the software reads the hardware wrong I was confused as well but it was working just fine . As far as gaming on my Zephyrus M 501 gtx 1060 model comes with single channel and I added more but I got maybe like 5 more fps if at all I added a micron stick to a hynix one and it's working fine cuz I remembered on the other Asus laptop it worked so I tried it on the newer one and it worked I put in crucial ram and running in dual channel . Working no problem accept I have quite a problem with the Zephyrus Gu501 it overheats ultra fast so I have to hit the over boost to keep the GPU clocks not falling all the way down to 1100s after a few minutes . Gets so hot it's crazy I hardly can undervolted it even it crashes after -74.5

Alexander Rewijk (4 months ago)
it means the world to an AMD apu for graphics performance (which can show a 2x gain on dual vs single channel) didn't think it mattered as much as it did when you have a dedicated GPU though (or rather, dedicated vram). quite surprising how much it can still hold back the cpu. then again, i bet it takes quite some memory bandwidth to keep feeding a 6c/12t CPU, i'm guessing it may matter a bit less when you have a 2c/4t for instance.
Jarrod'sTech (4 months ago)
Yeah APUs and integrated graphics seem to really love it, could be worth investigating in a future video!

Jarrod'sTech (4 months ago)
Sure, want to gift me some? 😉 haha but seriously at this point the issue is that I just have too many, it takes about a day to test them all, so I need to look at cutting some of the current ones that I have. I try to do ashes of the singularity, but at 3 minutes a benchmark run, all setting levels and doing multiple runs takes 45+ mins just for that one game to show a graph for 10 seconds so I tend to save it for CPU comparisons.

vorkot1 (4 months ago)
Hey Jarrod, me again, 1 I have more question I hope you can answer yet :) I noticed when doing a stresstest my laptop power-throttels (not thermal) according to XTU. The temps are alright and my battery preset is set to the highest. Weird thing is that it stays in 3.90 Ghz for a bit during the stress test, but then drops to 3.40-3.75 and fluctuates between that. Is there a way I can fix this, or is it normal for a laptop do drop it's clockspeed even during a 100% CPU stress test? I have an i7-8750H and I have not down-volted yet.
Jarrod'sTech (4 months ago)
No problem! -0.150 commonly works for me but I have had some that needed -0.090, yeah varies between CPU
vorkot1 (4 months ago)
Alright, shall do that! Strange, I thought the i7-8750H could go higher than what I currently have (-95 Mv), but I guess my laptop is different compared to the others. Thanks for all of your help tho!
Jarrod'sTech (4 months ago)
Yeah try lower it by 10 at a time and go again until it doesn't happen
vorkot1 (4 months ago)
I will! I set my laptop to -100 Mv and when I started Cinebench it BSOD with the error "Clock_watchdog_timeout". Does that mean I need to lower the value a bit? (more towards the 0)
Jarrod'sTech (4 months ago)
Yeah it is a bit odd, I guess the CPU is just too powerful for most laptops at 100%, let me know if you see an improvement with undervolting

I think anyone would prefer buying a laptop with enough ram in dual channel configuration. BUT...often manufacturers would only offer limited size configurations e.g. 16Gb with no 32Gb options. In that case I would prefer they ship it with one 16Gb module allowing me a cheaper upgrade path to 32Gb in dual channel. I hate it when I can only get a system with 2 x 8Gb configuration meaning I have to get rid of both, and buy two 16Gb modules
Jarrod'sTech (4 months ago)
Yeah good point, still personally I just want the option to customize as much as I want haha, although I can see how it would confuse the majority if you have too many choices.
maans le roux (4 months ago)
Reading about everyone's use cases and preferences I think its almost a impossible task to satisfy everyone. Especially the power users that would be watching your videos. I think they should offer a few basic configurations as they do today, in single channel for users who would never care about the extra bandwidth allowing them a easy upgrade path, but more importantly, also offer a "naked" configuration without SSD and RAM installed, and allow power users to purchase what we need separate and install it our self.
Jarrod'sTech (4 months ago)
Yeah would be good if they had more options in terms of memory.. Some laptops do and can be customized when ordering, but a lot of them don't which is annoying, and they tend to just go single channel to save a few dollars.
