Seeking help for vBios on RX470

[katapaltes]

Hi VuurVOS,
As it turns out, I was able to flash *either* 256kb or 512kb BIOS files onto the card successfully, with amdvbflash (v2.93) reporting that "80000H" (512kb) had been flashed in either case. I did not expect that would be the case. I thought *not* padding the file might have been OP's problem (but it was not). I thought one had to flash a BIOS file that was the *exact* same size as the chip, but I guess amdvbflash padded the file for me?

The card is now running using one of the three H5GC8H24AJR_PARTNER_SAPPHIRE BIOS files you posted above (thank you, btw), but it had a Code 43 in Windows' Device Manager. I didn't expect that I'd see a Code 43 using a good, unmodified BIOS, but it may be throwing a Code 43 because this former mining GPU has literally NO video outputs on it? atikmdag-patcher-1.4.15 fixes the Code 43 issue, but of course the card is only running at 1x. Now I must decide if I want to try and solder some tiny capacitors onto that PCB... :-o

Depends on board number as well. The bioses provided are ment for a E353 PCB. Not sure which PCB they used on your mining card.

It is an E353 PCB, so I did flash a correct BIOS after all. I didn't know that the PCB code was printed on a sticker on these cards, so thank you for prompting me to look for it.
