ASUS M4A79T Deluxe mobo
AMD Phenom II X4 945 3.0ghz
4Gb (2x2gb) Corsair XM3 1333mhz
Sapphire ATI HD 4870 1gb
For the last 2 and a half years, this computer was running top notch. I had it running at 3.2Ghz and everything was good. In the recent month that my computer is running MUCH slower than usual and my games lagged like hell. So I did a fresh install of Win7 64 and that didn't help. Then I saw that the windows experience index set my processor score at 3.7 where it use to be over 7.0. I look more into it and found out that my CPU is actually running at 800mhz instead of the 3.0GHz it use to run at. It turns out that the multiplier is stuck at 4x (200 x4) instead of 15x. I went to bios and made sure the Quiet N Cool is disabled but it didnt help. Also, I ran Prime95 and that didnt get the speed up to where it should be. I tried ASUS overdrive and set the multiplier to 15X but it reset back to 4x after I hit apply. I also changed the setting in BIOS to 200 x15 but that also doesnt help. The processor is supported in that version of BIOS im using because... first of all, it worked for 2 and a half years. The BIOS sees and recongnizes the processor and clock however its all messed up in windows. I also tried updating the BIOS but that actually gave more trouble than what its worth. The new BIOS caused it not to POST unless i clear the CMOS everytime I restart the computer. I had to downgrade the BIOS back to about the same BIOS I had it for it to POST correctly. And for the record, the new BIOS didnt help the clock either. I see alot of people had this problem with this processor when it was introduced back in 09 but a BIOS update fixed it for them.
Is there anything I can do to fixed this? Was there a windows update that screwed with my CPU clock? Or is my CPU screwed? I already formated the HD twice now and I am about to do it a third time because I am thinking maybe its a windows update. I am goingto run CPU-Z after a fresh install to see the clock speed without updates. I was hoping to squeeze another 2 years out of this computer before I have to build a new one.
