Some of the same problems here.
Phenom II X6 1090T - Bios 0906
TurboCore, Cool'n'quiet, and CPU Overvoltage aren't working together, but rather against each other.
I "disabled" the CPB (core power boost) and CnQ. I manually overclocked the processor by raising the multiplier to x19. I then changed the CPU Overvoltage to 1.45v.
CPUz shows the VID as1.328v. Core Temp shows the VID as 1.2750v. CPUID HWmonitor shows the CPU VCORE with values from 1.31v up to 1.50v. CPUz also shows the Core Speed for the chip as fluctating from 800 mhz up to 3800 mhz.
I actually watched the Core speed fluctuate from between 800mhz, 1600mhz, 3200mhz, and 3800mhz during a Prime 95 blend test.??????
