I was trying to overclock an AMD Phenom II x6 1075 on a M5A97 motherboard. I can't seem to raise the cpu ratio. It's forever stuck on 15. does the cpu have any overclocking capabilities?

The CPU multiplier is locked upward.

You can, however, disable Turbo, drop your memory speed one level, and raise the system clock.

The sweet spots in the system clock to return your RAMs to spec speed:
DDR3 1600 -- 240MHz
DDR3 1333 -- 250MHz

You should drop your HT link multiplier when combined with either of the above system clocks to keep the HT speed around 2000MHz.

Raising the IMC/NB speeds (it also has a multiplier) is a really good thing. For each 10% in speed the IMC/NB is raised above stock 2000MHz, memory bandwidth is increased 5-6% and latency is reduced 5-6% ... 2400MHz should be a slam dunk with the NB volts no higher than 1.2v

When you raise the system clock, lower the CPU multiplier and slowly...

When you raise the system clock, lower the CPU multiplier and slowly work your way back up ... test for stability and temps along the way.
