How Easy is it to Flash Bios?

[dpeel]

Good morning!

I bought a MSI Radeon RX 580 on eBay from a crypto currency miner. He said that he had flashed the bios with a mod for crypto mining. He said he would flash it back.

When I get it, is there a way to check it and if it doesn't have the latest bios, is it easy to flash it? I have never done this before.

Close all applications using the GPU, MSI afterburner, etc.
Open AtiWinFlash as administrator.
Save a backup of the bios.
Create a copy of that bios, and open Polaris bios editor as administrator. .
Here you can change voltages, memory clocks, core clocks and timings. You can adjust those with MSI afterburner after, except for the memory timings. Take the “straps” of 1500 and copy paste them to all the above straps (up to 2000 inclusively) – or even better – use the one step timings button on the latest PolarisBiosEditor. Save bios.
With AtiWinFlash, open the new bios and install it. This can take a minute. It is preferable to use the command line interface, the GUI works also – its just a bit more risky to use.
Reboot.
If you run into a driver problem, you may need to reinstall your video drivers (this may always be a good idea). Run DDU in safe mode, this is the best way to reinstall drivers.

Some experienced miners have uploaded their own bios for everyone to use.
Make sure you have the exact model the bios is made for, with the same memory type: hynix, elpida or samsung.
If your card is unstable, try copying only the straps for 1625 and over, or 1750 and over (especially if you have samsung memory. Start with the 1750. Don’t forget to set memory at 2000 for example in MSI afterburner, then reboot the rig. You should see good results after. Check your HW errors/incorrect shares – if you have some – reduce memory clock

Sorry, I didn't realize I'd posted twice. The one response I got is way above my understanding.

Is there a bios file name for the original? Is there someplace to just download the original or current bios file?

I assume this is the right program to access the video card bios. I assume you would use this to flash the video card bios.

I assume GPU-Z is a way to see the bios file and setting?

I like to use Speccy for system info. You can use it to double check your results.

I'd also run a game while using MSI Afterburner to observe GPU clockspeeds and temps and general performance. You should be able to see right away if anything looks off.
