Hi guys,
I have a problem with my Gigabyte R9 280x (GV-R928XOC-3GD-GA). I bought it over ebay a month ago and had some overheating problems with it. Tried putting more fans in my pc and lowering the core/memory speed. Nothing worked. I think that today I found out what the problem is. The BIOS on the card is a GV-R928XOC-3GD.F60 which is, as I found out a bitcoin mining optimized one. That means that the ebay ********* sold me a card with a flashed bios! And now I can't play hardly any games without the card reaching >90°C
I would like to flash the original BIOS on the card .... but how? The gigabyte website (http://www.gigabyte.de/products/product-page.aspx?pid=4847#ov) offers 2 versions of which I cannot use anyone. The official tool won't work. I need help
My question is: which bios to choose and how to flash it on the card.
I would appreciate an answer,
Thank you very much!!!!
Here are some pictures of the GPU-Z and the BIOS Tool.
