AMD FX-8350 OC fails/unable to OC properly

[Aville]

Hello, so I've decided to overclock my cpu since it's pretty common with this one. But after my first try I already failed. I was trying to go for 4400mhz at first with 220mhz bus speed but I wasn't even able to get past login screen before blue screen. Then I looked at my voltages and saw that I was running pretty low @ 1.2 or something I guess. Then I changed it to 1.35v and 215mhz bus speed. No good after launching prime95, I got a blue screen. Third try, 210mhz bus speed. My 8th core stopped working after 4 minutes and the rest did fine after 30 minutes on prime95. Temps were at max 66 celsius. I really don't get it what's wrong and as I bought my hardware used the last owner told me that he got the clocks to 4,5ghz with the evo 212 which I'm using aswell.

Cpu-z and HWMonitor shows that my cpu core voltage atm is 1.328-1.336v Though it's set to 1.35 from the OC Tweaker.

Specs:

CPU: AMD FX-8350 @ 4,2ghz
MOBO: ASRock 990FX Extreme4

Ask me for more information I'll be checking this thread really often as I want to get this working ASAP.

Have a reading through there. Took me days of reading and tweaking to OC, so don't rush for ASAP. It's not urgent, your PC works and a couple hundred extra mhz is going to make or break your system that it has to be done ASAP or the world will end.
