I flashed my RX570 8gb Micron Nitro+ but hashrate unfortunately remained at 4Mhs. This doenst work for nitro+ but maybe only for pulse . Thank you anyway and if you find out what to do with nitro+ please publish .
Hi,thanks for the video. I have Sapphire Pulse RX570 8G MICRON and I did everything like you,but when I open ATI winflash I got just one strap instead of 2. I wonder why. and evey time I try to put a edited bios the computer would not start. Can u help me?
Hello could you please help me
I have a Gigabyte RX580 8GB Micron mem and i only have the following timing straps:
What should I be chaning in my case??
Thanks for the help in advanced
Милый TV I copied the 1750 string to the 1875 and 2000. It didn't make much of difference. It boosted it from 28.2 MH to 28.5MH but it wasn't fully stable in my case. It would sometimes drop to 27.something and fans were speeding a lot more.
I have a set up with 2 MSU armor rx 570 8 gb out of the box I was only getting 18.5 m/h I bios modded one card and it bumped it to 20.2 but when I mod the second card claymore no longer recognizes any and cards. I had to go back to stock bios for them to work again. I can mod either one but when I mod both it doesn’t want to work. Any ideas what my issue might be? Also it seems my stock hashrate is low only being 18.5 do you know why that might be so low? And lastly when ever o try to overclock any at all with trixx my hashrate goes down. Any help would be greatly appreciated. I’m running Windows 10 home on a h81 pro btc 2 mobo an i3 processor. I am also running the amd blockchain driver. Thank you for your time.
Thanks for sharing. While following the same steps, after modifying the rom and trying to flash it, AtiWinFlash throws: "this version of vbios is already installed". Googled it, but no info came up regarding the cause. What could be wrong? Thanks!
I know this was a while ago but wanted to thank-you for posting this. I will commit to supporting your efforts as I know this takes work and dedication and should not be taken lightly. Your efforts are appreciated. (This got me through a struggle I was having with the RX-570)
why wouldnt you use the 580 8g video i have? anyways, PBE has updated, now there is a one click timing straps option, and thats probably what you want to use now.. i need to update and do another video
Hello Cryptomined! I am having a serious issues with all my new Sapphire rigs, I am using this mod on my GPUs and they reach high speeds but I cant mine for more than a few seconds, even at speeds of 23-26 Mh/s (I cant even mine with stock settings and never-modded-GPUs).
I am using Win 10 pro (UEFI) up to date,
Biostar TB250 BTC (updated),
Processor i3 7100,
8gb Ram 2400mhz,
1200 watts for 6x Nitro+ 580 8gb Hynix mem (I have the same issue even with a single gpu connected),
Also tried drivers ver 17.5.2 and latest ver. without mod.
Most of the times I get the THREAD STUCK IN DEVICE DRIVER and TDR Blue screen problem, or the ataidlxx.dll issue.
Also tried DDUing and reinstalling the mixed driver over and over.
Always using Claymore DM 9.8.
Already increased the virtual memory to 16gb.
Processor temp is always nice and cold.
I am really running out of ideas here and I really need your help guys!
Did this mod on a Sapphire RX 570 4GB Hynix and see no change in hash rate. None. I even tried Anorek's canned BIOSes and same thing. Best I can do with ETH is 24.1 MH/s with a high memory clock.
This mod doing nothing seems to be a common problem. Someone outta do a video on this :)
I have a question about gpu bios modding. We're modding gpus but is it harmful? Does it effects card life? I do mining with lot of gpus and i want to use my gpus a long time. I'm afraid of card life with gpu modding? Can someone tell me that is it harmful or not?
I flashed both graphics card but one is stuck at 24MH/s while the other is at 28MH/s... Does anyone know what I'm doing wrong?
Both cards are RX 570s (exact same cards)
myantispambox if you are on windows use MSI Afterburner no matter what brand your gpu is; then mem clock 1855 and core clock 1100 plus power -45(the less the better). If you are on ethOS, mem and core clock the same and powertune 3. Let me know if this helped you! As for the bios mod, read my previous comment, it'll seem that nothing happened but when you OC, you will see the difference.
Also you can try to push my values, but it wasn't stable for me.
Hey, I spent a couple of days trying configs and this is what got me the best result: copy 2:1500 to 2:1675, 2:1750 and 2:2000 (570 8GB Micron).
After that, OC with windows was unstable, but in ethOS is working great. I have
Core clock: 1100,
Memory clock: 1850,
Getting very stable 26MHs, but yeah, you can OC a little more and get to 28MHs(or if you are lucky some get to 29) approx and decrease the voltage. Still, I didn't like the result given the stability and GPU crashes over time.
I hope this helped!! And feel free to try every config and share!
Hello, i just built a rig 4 rx 570 strix oc 4gb i'm using the latest driver (17.5.2) with calyomre 9.4 in windows 10 but it keeps shutting off the pc every hour or less, do you know what could be the problem? i tried to use 1 750 g3 gold psu but though it wasn't enough and that it might be undervolting so i'm using 2 of those now, still same issue.. thanks
Thanks! Works on XFX RX580. Summary of my settings below...
Polaris copy 2:1750 value over 2:2000 and 2:2250
Scratch the previous Trixx settings. Using AMD Radeon Settings instead.
Make all changes and apply before you start the mining software.
Core: -20 on the slider
Core voltage: auto
Mem volts: auto
Max temp 80, target 65
This produced the same results but isn't crashing every 4 hours
Before: 22 MH/s
After: 26.5 MH/s
Watts: 105 to 115
Edit: HYNIX Memory
This is the only affordable option left since demand is way up. I'm going to grab one of the XFX RX 570 4GB ($200) from BB this afternoon if still in stock to finish my rig (said they were in stock yesterday). If I can get one, I'll post my results. It is now Tuesday 5/30, and I should be getting the card tonight. Might just make a video on the XFX 570/580.
(RX570) After modding the BIOS on the and flashing you should get over 25 Mh/s. Then go into the AMD Radeon Settings program, global settings, global wattman. Boost memory anywhere from 1950 to 2000 to see an increase in hashrate. Drag core frequency slider down to -20 (or more) to decrease wattage.
Not sure if wattman settings only without flashing would give you an increase in hashrate.
OK, I got it working...
XFX RX 570 4GB from Best Buy (now sold out everywhere thanks to ethereum's rise)
Use same Polaris from this vid's description
Copy 1:1500 value over 1:1625, 1:1750, 1:2000
Before: 22.25 Mh/s
After: 25.25 Mh/s
Tuned (Economical): 27.5 Mh/s, 90W
AMD Radeon Settings: -20 on Core Freq., 2000 on Mem Freq.
Tuned (Performance): 28.75 Mh/s, 110W
AMD Radeon Settings: Default on Core Freq., 2000 on Mem Freq.
Help me sir, I have powercolor rx570 4gb with hynix vram.. but i can only reach 21 mh/s with modded bios and overclocking, I use timming 2:1500 copy to upper then I use 2:1625 copy to upper, but no effect, It seems my vram type is hyinx and elpida (EDW4032BAB and H5GC4H24AJ).. Can you give me the solution please!
great video!!! you are the best!!!
Does it work with RX570 nitro+ 8gb as well?
is it better RX570 nitro+ 4gb or 8gb (+20$) or RX580 (+additional 30$)?
I'm building my first rig and I need you help to choose the card :)
Thanks a lot for your help and the top videos!!!!
If its micron ram it should be the same, if its other vram than it should be similar but I don't know for sure, haven't tried with other cards yet (though I have one other 570 4g card to test in the near future)
I've got a good deal on the table for a Gigabyte rx580 8gb. Not sure brand of memory but obviously hoping for Hynix. I don't see it used often in forums and youtube. Is there something about this brand? It seems too also that Micron is no longer the kiss of death for mining like in the rx4xx's. Your thoughts?
I also have not heard anything about the gigabyte cards this round. I know with the 480 they got hot easy, but Im not sure now if they have improved on it. I like gigabyte for Nvidia cards, but I think some of the xtra heat on the 480 was from reusing a heatsink from nvidia cards.
my Micron seems ok, though i actually get better watts on my 580 when i underclock it and undervolt it
hi! i tried this method, copied the last rows, and now my card is doing 26MH/s tuned with afterburner, core:1100mhz, mem:1900mhz. tried this with 1200 core and 2100 mem, with 30%+ powerlimit, done 28+MH/s, but it crashed after a few minutes
can you tell me your settings? maybe I can learn from them
hi! can you pls help me? I have the same asus rx470 strix micron 8g oc (22/24 MH/s)
did you use the original polaris editor, or the one by jaschaknack ?
did you copy the 2:1750 to 2:1875 and 2:2000 or did you do other changes?
what tool did you use to OC? afterburner or wattool?
Nebojsa Zrnic Hi One question. Im waiting for same card Sapphire Pulse RX580 8 GB. Did you modify bios from this guide for 570. If not could you plese give me some advice what timings to change. Thank you
Hi I bought the RX570 NITRO + 8GB with Micron memory. But before the MOD bios I had about 24 HS on the ETH. After MOD bios, I have the same as though nothing has changed, but the values are different. Why can it benefit me anyway? Thanks
Hi miner comrad. (:
I bought this card too, and i have already moded it.
Do the same steps how talking in video but copy timing from 1:1500 to 1:1650 - 1:2000. After reboot patch your driver, and reboot again, and you will see a nice result. (:
Original bios - 22.3Mhs, after - 25.4Mhs
Sorry for my English
sorry I'm a bit confused about the 570 versions from Sapphire.. which one is best? I can't find the 470 anymore so I was wondering if I should get the 570 Pulse for $299 (AUD) or a 580 Pulse for $339 (both 4gb) or the 580 Nitro for $369 4gb as well? what do you recommend? Thanks in advance. Great videos BTW.
I have not bought any 4G cards, but from watching a russian video I saw that it was the same as a 480 4G card. might depend on memory... 4G cards with samsung are generally faster out of the box... like I have one 470 4g with samsung and it does 24.5 on eth out of the box
Thx for correct polarisbioseditor. Tips, command line atiwinflash is alot more reliable, and can do more than 3 cards. Also, edit voltage in the Claymore batch file, it is a lot easier (if you have more than 1 card especially), and doesn't reset on crash.
yes you can overclock or downclock in PBE so it sets it in bios... you just adjust the clock settings in the clock column.. but you need to adjust the lower clock values also (dont neeeed to, but you should).. so try to make a linear decrease after you set your max clock
i'll try and report back..another question, can I overclock and undervolt the bios mod via polaris editor or is it just for the timing so I need to use trixx for the clocking park?? as my card has not yet arrived I am just curios
sory i've question, how abot elpida memory,
I have purchased Sapphire RX 580 Pulse 4GB with Elpida Memory, I am looking for a tutorial, but did not found for this GPU series/elpida memory. (sory for bad english :D)
I have 2 470 4g with elpida, but they are kind of new, from an RMA so i have not modified them yet... I have a long list of things to do over the next few days so I will try to do an actual how to video on elpida over the next week sometime
