Hello. I have AMD FX-8350 Eight-Core (Vishera) cpu, my motherboard is asus m5a99x evo r2.0. Both Aida64 and CoreTemp show that only #0,2,4,6 cores are loaded while #1,3,5,7's load are from 0% to 4% or so. FPS in games(BF4, withcer 3) suffers a lot from this. It happens not only in games but always. 4 cores are loaded up to 99% and the other 4s keep resting. I've tried resetting bios to the default settings but that didn't work. No over-clocking had been done.
OS: Windows 7 Ultimate 64-bit.
RAM: G Skill RipjawsX F3-17000CL9-4GBXM x4.
GPU: AMD HD-7950
