Hello,
Sorry for the paragraphs but i'm beyond frustrated at this point. I have 2 RadeonHD AX7990 6GBD5-M4DH in my altcoin miner and I decided to flash a custom bios for overclocking past 1100mhz. Everything worked at first but I noticed my WU in cgminer had dropped by at least 20% and I started getting more reject shares than ever before. I switched the switch on my card back to my backup stock bios but i was still getting the same problems. I tried using gpu-z to save a copy of my stock bios to reflash the custom bios back to stock but it won't let me save the bios for some reason.
I did happen to find the master and slave bios for my card but when i flashed them over my custom bios, it bricked the card while in that bios. Now when I turn my computer on, I heard the post beep but there's no display, although i CAN work my way back into the DOS mode to blindly flash bios with atiflash (the directions are easy to memorize). Although when I try to flash the stock bios' i found online over the custom bios, it does nothing at all. Just a black screen.
I'm starting to lose hope and a lot of sleep here. I was wondering if anyone could possibly backup their master and slave bios from their malta 7990 and send me them and perhaps guide me on how to get out of this whole mess and get my display back. I appreciate any help I can get. I'm sorta desperate at this point -_-
tl;dr Need stock malta powercolor 7990 master and slave bios and help unbricking my cards. Post beep, no display. please help.
