A couple of weeks ago, I bought a used Sapphire Nitro+ RX 570 8GB off ebay (I know, I know, probably an old miner card but the seller has 100% with thousands of reviews). Since it came, and it worked (stress tested it with furmark for a few hours, it never went over 65C), I've mostly just been enjoying the upgrade, which was a big step up from my old R7 260x 2gb.

However, the last couple days, I've been poking around under the hood, looking at the clocks and temperatures in game (was only watching FPS in game), playing with small overclocks (no voltage adjustments) and checking out if the other bios performed differently.

Everything seemed normal until I noticed that the card never came close to reaching it's stock core speed with either bios even when overclocking, which is supposed to be 1340mhz/1750mhz core/vram. I got ATIFlash to see what bios is on there, and there are two different ones.

I've found them both on techpowerup, and they're labeled as unverified. I assume the bios is underclocked for mining purposes, and that's also maybe why my max temperature was ever only ~65C. So I've downloaded both the available verified bios from techpowerup, and just wanted a second opinion before I start flashing.

I know I'd have to mess up pretty bad to brick my card, but just want to make sure my information is correct and procedure sound before I proceed, only thing I've ever done with a bios is update a motherboard.
  • Step 1: Boot with bios 2
  • Step 2: Flash bios 1
  • Step 3: Boot into bios 1
  • Step 4: Flash bios 2
This might be altered slightly if I'm on bios 2 and I flash bios 1, and it flashes over Bios 2. Then I'd just boot bios 1 and flash bios 2.

Do not flash the bios you referenced to, it will brick your card. I will help you track multiple down

Give me time please

Ok, thanks for your help.

Just out of curiosity, how did you determine the stock biosi I linked would brick my card? They're the only 2 available for my specific card in the database.

2 for sure will brick it due to memory tables being for micron or samsung only, when you need hynix.

Experience of restoring cards to working status.

Here's the tool.


These files will work, all E366, Hynix memory.

This is overclocked to 1360/2200

The rest are 1340/1750










This has a foreign description about code 28/34 Do not install unless instructed

If you wanted we could experiment with a rx580 nitro/+ bios even...

Been reading through your post history, I don't doubt your knowledge here, was just curious so I could figure it out myself next time. I'd be interested in playing with the OC or 580 bios, once I get the stock clock one working. The second stock bios for this card was a quiet mode or something, I don't need that. Anyway, thanks for the links. Should I just flash using the tool, because I was reading the guide here that said to make a usb boot drive and do it from command prompt not Windows. It was also pretty old though, so I didn't prep the USB yet because I wanted to ask if all the software links in that guide are still relevant. Thanks.

Yes just use the tool within windows. DOS can't detect the card, command prompt can

I'll give it a shot, thanks again. Will update tonight.

Besides raising the stock clock speeds, is there much benefit to flashing the 580 bios? It can't unlock any TMUs or SPs or anything for extra performance, right?

Higher power limits and more legroom for overclocking

Sometimes shade processors are unlocked

Successfully flashed the first stock clock bios on your list to bios 1 (switch to the right.) I got an error message "VBIOS image not found" when trying to flash the OC bios to bios 2 (switch to the left.) I'd be up for trying a different OC one, or a 580 one you recommend.

Only flash the side you were trying and failed to earlier, leave the working side alone.

Rx580 E366 8GB
1366/2000

1350/2100

1380/2100.

Try them and get a temperature reading (if they work) these are slight clock bumps but if you feel the card can push more beyond 1380/2100 then we will try 1411 and that is most I would try.

Yeah, I figured only flash the failed side. So here's where I'm at. Tried the third first, and the first second, they both hard froze Windows halfway through the flash. Rebooted fine with the old bios each time. Did the second one last, and it actually successfully flashed:


As you can see, there's a few issues. I'm missing sensors, drivers, etc, and didn't gain any shaders (wasn't really expecting I would). I tried a few different driver versions, but the installers wouldn't even run. I put the original bios back on 2, and I'm just going to OC the stock bios on 1 you found. I've done a modest stable OC of 1400/1950.
