Hi! i need some help with my GPU, about 7 months ago i buy a used ASUS RX 580 8GB, when i bought it i had some temperature problems, so i decided to send it for maintenance in a store here in my town, after a month of that, i started to have failures with the gpu, as soon as it has a little load the pc crashes, it gets a solid color crash (whatever is the majority at that time on the screen) and the pc restarts, with the simple fact of putting shaders to minecraft or doing the FPS test of CS2,is enough to crash my pc, and I started having crashes in valorant now too, a couple weeks ago I could play the game fine but now its just crash with driver timeout.
Looking at GPU-Z I see that the version of my gpu and the type of memory is different from what it should have according to techpowerup, according to gpu z my memories are Micron, but the version of bios that has flashed my gpu says that its memories are suppose to be samsung, even the sticker in my gpu cooler match with this GPU version (ROG-STRIX-RX580-O8G-GAMING), I see in the BIOS database this version of GPU: ROG-STRIX-RX580-T8G-GAMING, that it's almost the same of mine physically, and in his BIOS the memory type is the same as what I get from GPUZ (Micron), should I flash this BIOS version? I see that both have different versions of Polaris 20, the O8G version (which is supposed to be mine) is Polaris 20 XTX, and the T8G version (the one whose bios says it has Micron memory) is Polaris 20 XTR.
Or do think it's basically not a BIOS problem and my gpu is just dying on its own.

Cards have multiple revisions. One moment a manufacture puts Samsung K4G80325FB on their cards and another moment they put Samsung K4G80325FC on it.
To find the correct memory support, you need to remove the cooler and find out what is physically on the card since software reading is not always 100% reliable.

Likely your bios has been uploaded in the bios collection but as unverified upload:

The problems you have is not bios related. Your card is dying. Could be VRM or faulty memory (controller).
