I upgraded my motherboards bios because my ram wouldn't run stable with the previous version. I get through to windows and everything seems to be stable. I stress test it with Prime95 and everything is good. But then I turned off my PC and my bios were back to the previous version. I also dont see my ram speed in task manager anymore which is strange. I have a gigabyte aourus pro wifi (rev 1.0). Whats wrong with my task manager and why do my bios reset everytime I turn off my PC?
