Hello , i have Sapphire RX 580 Pulse 4GB Hynix memory and it looks like I am the only one that have them . i`m looking for modified bios or straps. 2:1750 to 2000 does nothing .
24.5mh stock which is nice , but  28-29 sound better .
Any help or advice please

Hi! I have 6 pcs from this card. Today I tried to mdoify bios and bricked one of the cards. I am with Hynix and I havn't 2:1750. My timings are very strange: 21645256, 3355496, 3361497 and etc (look these pictures).

Now it mining with 24.7 Mh/s ETH and 730 Mh/s SC.

Motherboard: Gygabite H81M-DS2
CPU: G1840
RAM: 4GB 1600 Kingston
SSD: Samsung EVO 840 120GB
PSU: Cooler Master GX650
DRV: 17.4.3 with copied WT6A_INF from 16.9.1
Stock clocks and -60mV

Do you know some way ti unbrick? Which is the best drivers at the moment for these cards? Why I change clocks performance is bad than stock?

Thank you!
I am using the latest drivers and so far all is good . try  installing the bricked gpu direct on the MB(no risers).

Hi guys! Thank you for help. I unbircked my card by 1+8 method. Exactly 1+5 because pins are 1 and 5, not 1 and 8 but anyway. It works. Now I am looking for working BIOS mod because 24.7 is too low I think.

Also I  can't understand why I change some clocks (no matters up or down) my hash rate goes down. Best clocks are stock.

Hello, I was going to buy 470s but I can't find any in stock.

Is it good idea to buy 570/580 instead? Is there still consistent problems with 6 cards at same time? I heard people were having hard time making it work but has it been fixed now? Would I risk spending a lot of time trying to make them all work or has it been easily fixed by now? Sorry for not reading whole thread.

Also, would 1200W PSU be enough for 6 470s?

Doing 30MH on the RX 570 Pulse with -200mv (775mv core voltage). Pulling 95 watts at the wall Cheesy

Probably something not right show some screens of gpu-z and hwi (memory errors) please

Sure thing...GPU3 is the 570 pulse card, been running like this for days had to restart the other day so thats why its "only" at 22 hours stable.

I use this tutorial: https://forum.ethereum.org/discussion/9443/bricked-your-rx-480-due-to-bad-flash
But I solder thin wire instead paper clip. My chip was 25Q40 which is 4Mbit SPI Flash.

Maximum that I reached is 26.5Mh/s ETH and 780Mh/s SC on dual -90mV; stock clocks; 140W consumption GPU-Z.

if you undervolt a bit and do not dual mine (or use powerlimit) , than 1200w should be ok

there is no much difference in 570 vs 470 but 470 is a lot faster on cryptonight  and bit slower on ether

@Junkey, stable settings depends on GPU model, BIOS mod, driver version, memory manufacture and ..luck. I have to make a tests.

RX580 Sapphire Nitro+ 8GB Hynix at 1150 Mhz Core and 2150 Memory and Voltage -75mv - Trixx
RX580 Sapphire Pulse 8GB Hynix at 1150 Mhz Core and 2150 Memory and Voltage -75mv - Trixx

Maybe not all cards can be undervolted -75mv OR maybe more then -75mv

Strap copied to 2:1750, 2:2000, 2:2250:

here is a blank, check you copy all without the blank (forum changes it?)

ETH: 30.1 - 30.3   -   100% Stable, 0 Errors, about 2 weeks



Long time i tried bios mods and many other memory straps, this one is the only working flawless with 30 MHs.
Other straps got me lower MH on memory overclock or blackscreens and artefacts

Hi, thanks for info, this strap and frequencies also worked for me (RX580 Sapphire Nitro+ 8GB Hynix).

I went little bit further and set Core Clock to 1204MHz and Memory Clock at 2200MHz, voltage -74mV.

Now getting 31.0 - 31.1

I'm not sure if 2200Mhz makes difference compare to 2100 for this performance timmings...
I would prefer lower it'll be more stable and also less heat...

thank you!

I have tried 3 brands 5xx cards, so far the best personally for me is sapphire.
I am now using Pulse 570 4GB, bought on really low price. Now hashing with 29,3 ETH + 670 DCR.

When I lower memory clock from 2200MHz to 2100MHz I am getting 29.6 Mh/s, so difference is 1.4 Mh/s, and temeperature went from 65°C to 63°C

When I do exactly this, I get "Invalid HEX String" from polaris bios editor.After that it crashes but saves the file (0 byte file). Is it the same with you guys too or is it just me ?

First copy strap into notepad and delete white space, there is one white space in HEX string. Maybe that is a problem.

Guys, on my bios higher frequency is 2000. I haven't 2050 or 2100. Is there a way to add it or it isn't necessary?
