Hi guys, after seeing a Topic(that is closed) in this forum about Bios modding GTX 970/980, I tried contacting the creator of the thread to send me his bios mod(no success). After some days, I decided to tweak the bios by myself and learned almost everything on maxwell bios tweaker.
Stock GTX 970 clocks: 1126mhz/3505mhz(core/memory) 1266boost(core clock) [Galax OC edition] ---- 1.212mv
My Bios modded GTX 970 clocks: 2164mhz/4111mhz(core/memory) NoGpuBoost(disabled boost) ---- 1.125mv (yeah, I undervolted it and it is stable)
Tested on games and benchmarks, working great for daily usage, temps not going over 75ºC(Custom fan curve, air cooled)
FPS test on Rocket League menu(I have disabled 250 FPS limit):
BEFORE= ~200fps
AFTER= ~300fps
PS: Make sure you have a good PowerSupply(I have a 700w 80plus gold). Max PowerConsuption(W) I measured was around 170W(using GPU-Z).
with this bios mod I actually improved by 50% the performance of my gtx 970 and also decreased frametime a bit. If you guys wanna give my bios a try, I will leave the file uploaded here. Cheers
