[SOLVED] Bios update fail

[firecats2580]

Heyo, so I recently got a used Sapphire r9 280x from ebay. I plugged it into my computer, where it worked but the bios was old, so I tried to update them. I went on to atiflash and found the most recent bios update and installed it. After the installation my computer no longer would display from the card, even though the fans were spinning. It looked to me that my computer completely didn't recognize that a gpu was even plugged in, and could only be launched in safe mode through the on board graphics. I know the computer isnt broken because I put my old gtx 760 back in and it is working completely fine again . But that r9 280x doesnt work at all anymore. Does anyone know whats wrong? I have looked everywhere, but nothing seems to work, is the card just broken?

Looks like the memory timings on your new BIOS are off. You can probably flash it back to the one you had if you saved it.
In general, BIOS has the GPU Core model, memory timings and power options. You cannot just pick one with a similar name and use it.
Try to read the product ID from the sticker and find a good BIOS for it using this ID. I posted a guide on how to flash it with external tool.
