AMD RX580 8GB Error 43
AMD RX580 8GB Error 43
I recently purchased an RX580 8GB at a very low price, it was a decent offer even though it isn’t functioning properly. Before selling it, I’m curious if I can repair the card using my limited experience. Here’s how things went:
1. I bought it for $10 and initially connected it to my motherboard, which caused the PC to restart repeatedly.
2. I tried a shorting method on the BIOS IC pins 1 and 8, and the PC started up, but the card wasn’t detected even after using AMDVBFLASH.
3. I used a programmer to flash a BIOS that wasn’t specifically for this card, but it worked with error 43 (no display).
4. I struggled to locate the exact BIOS for this card; I found an AXRX 580 8GD5 OC V2 from PowerColor with SKHynix H5GC8H24AJR VRAM.
5. After flashing the BIOS with timings (also for a PowerColor GPU), GPU-Z reported 8192MB of VRAM, which seems correct based on my basic knowledge. Still, error 43 persists and there’s no display.
6. I discovered a capacitor behind the GPU core that might be shorted in the VRM, and I accidentally removed it (my mistake). Now it’s missing one capacitor.
But given my limited understanding, I believe the VRM is set up in parallel, so removing one capacitor shouldn’t cause issues.
Any assistance would be greatly appreciated. I’m still searching for the precise BIOS for this model.
Welcome to the forums, newcomer! Check GPU-Z to identify fields with zero(0) or N/A values. Combined with error code 43, this suggests your GPU is dead.
Old GPUs from that time were heavily used for mining and were rarely bought unless you knew the owner personally and understood how they were used. You might have a paperweight.
You might attempt to replace the capacitor and ensure traces aren't damaged, but I doubt you'll be able to get this card up and running, given its price of $10.
