Overclocking FX 8350 - auto underclocks during Prime95 Small FFT

post #1 of 3
Thread Starter 
I'm trying to overclock my FX 8350, and I'm currently following this guide (http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard), as well as I can.
Problem is just, I've changed my ratio and currently doing the 10min Prime95 test, but the CPU keeps decreasing the voltage and clock for about 5 seconds whenever the temperature gets around 50 degrees Celsius, which is every 30 seconds. It keeps this decreased clock until the temperature gets under 30 degrees. So I'm not sure if my stability test is even valid, since my CPU isn't running at max for more then 30 (or less) seconds at a time.
I've disabled every power saving feature in the bios that I can find, and I've also set my target CPU temperature to 55 degrees. Can someone help?

Specs:
FX 8350
Cooler Master Hyper 212 Evo (or plus, I can never remember)
AsRock 990FX Extreme3
Corsair GS700 2013 Edition
2*4GB DDR3 Corsair Vengeance

You need to disable Cool 'n' Quiet in the BIOS, this throttles your CPU to keep it under safe operating temperature.

I had disabled all of those features already.
But now I suddenly experience that 2-3 workers in Small FFT Prime95 have an error within the first 2 seconds of running. and I didn't change anything. (I'm trying to remember if I did, and the only thing that comes to mind is increasing the temperature threshold to 58 degrees)
