Hi guys,
Since this forum seems to be the most reliable in terms of overclocking and GPU in general, I wanted to know if you can help me.
Here's the thing, two weeks ago, I bought a new computer, it was in fact a kit that I built myself.
Everything went well, building, installing drivers etc. I played BF4 with ultra graphics settings.
And, one week ago, everything started to mess up. My GPU started to switch from 3D mode to 2D mode in a middle of a game. My GPU is an AMD Sapphire R7 260X 2Go.
So, I tried to figure out what was the problem : I re-installed several versions of the drivers and still the same issue. Then, my GPU stayed locked in 2D Mode (150Mhz(Core)/300Mhz(Memory) instead of 1150Mhz/1650Mhz).
Ever since, I tried so many things like modifying my AMD Overdrive setting, my Windows power options. Nothing solved the problem.
So I installed OC utilities such as RivaTuner and manage to get my GPU memory clock up to 1650Mhz. But the core clock stays at 300 with sometimes 750Mhz peaks (according to GPU-z).
I just tried to flash the bios of my GPU but couldn't modify the .rom extracted with RBE because it didn't recognize it as an AMD bios. I just tried to flash with the default bios found in TPU BIOS Collection, vainly.
I don't know what to do .. If you need any further information in order to help me, just let me know, i'll be as quick as possible.
Thank you in advance
PS: English isn't my native language, so let me know if you have trouble understanding my problem.
