OK so I've tried this BIOS https://www.techpowerup.com/vgabios/192936/sapphire-rx470-8192-161220 along with the atikmdag-patcher and it's still showing 0/0 GPU and Memory clock. I'm not sure if the hardware itself could be causing the issue but the thing is the GPU fan runs normally, it's detectable and flashable as well so I thought it couldn't be a hardware problem.

Question:
- Do I need to DDU and reinstall drivers after each flash?
- Do I need to shutdown after each flash or restarting is enough?
- What could possibly cause the 0/0? And if there's a special BIOS for these "manufacturing defect" cards, the BIOS which runs 1150MHZ and lower should theoretically work correct? Assuming it has the same Micron memory.

Thanks for your help!

I received the card in the condition that none of the 4 BIOS are working. So I'm trying to fix it by applying the original BIOS. I'm not even looking to boost the hashrate but rather just get the card working normally first.


I have tried the above BIOS and it does not work. I tried flashing on 2 different PCs and they still just show 0/0 GPU and memory clock. What I need is the E388 BIOS which seems very rare since most cards are E387, E353 and E347. I read that E353 should be similar to E388 so I tried all of the E353 BIOS and none of them works.

I try to avoid flashing BIOS that lacks support for the Micron memory but none of them works.

I wrote to their tech support and they couldn't be much of help unless I can provide at least one of the original working BIOS.

Thanks for everyone's reply!

Thanks for your reply. I am actually trying to find the original BIOS, not a modded BIOS. I received the card with the BIOS already messed up (which cannot be used at all) so I am trying to return it to working mode. I know the hardware itself is working fine. The fan turns on, GPU detectable and BIOS flashable.

Problem not solved but I gave up.
