Weird Turbo Core Problem

[Germinator]

Hello world

 

I've got a phenom 2 x6 in my am3+ board and can not use the turbo core feature. when it's turned on, the "turbo" cores clock down to a minimal multi (4x) but still get +0,125V.

To get that little extra speed i increased the baseclock (250mhz), which is causing trouble when that machine's uptime is about 10h.. BSOD

tried upping vcore and nbcore to 1,425V / 1,2V  - no effect

 

I would like to use a lower baseclock with turbo enabled to get a fast and stable system.

 

Temps are below 50°C on load (already added that extra 13°C for thubans)

Mobo is a gigabyte ga-970a-ud3p rev2 (BIOS up to date)

Cpu is a 1055t 125W

 

Does anyone know what to do?

 

please excuse my poor english.. my uptime is about 20h without bsod
