Hi I have the AMD FX 8120 and ASUS M5A97 AM3+ . I used the AI Suit2 that comes with the motherboard CD to overclock my pc. It overclock everything for me but the problem is, When i turn on my computer i get 3902MHz but when i restart my computer I then get 3842MHz. Why is my CPU MHz keeps changing? Why doesnt it keep at 3.9?

It could be "APM".

Some older BIOS versions don't even list the feature but newer BIOS versions list it and allow you to disable it.

I remember it as "Advanced power management" or something like that.

It's a power-saving feature that causes the CPU to downclock. Unlike other power saving features that cause the CPU to downclock under light load, (Which is good) APM causes the CPU to downclock anytime it looks like TDP is going to be surpassed--even undr full load. (This effectively negates any OC)

Go into your BIOS and look for a feature called APM. If you can't find it, you probably have a BIOS version that doesn't allow you to disable it.

If you find it, disable it.

Then you probably have an older BIOS version. I had to update from F5 to F7 on my son's friend's UD3 to access the feature and complete his overclock.
