Hard to say...what's the vcore reading at load? Your cpu is idle in that screenshot.

I know I can prime at a vcore reading of just less than 1.25v load at 4.5 ghz.
If you're completely locking up at 4.2 ghz and 1.20v before you can even run any programs, then that definitely isn't a good sign, since you usually need at least 0.05v higher if you freeze right after windows loads...

Can you prime at 4.1 ghz with a LOAD vcore of 1.17v? (no idea what you have to set it to in bios to do that at load).

Well since at default setting it showed a VID of 1.20 I manually set it to 1.20v in bios. Under load in CPUZ it dropps below that 1.20v, not sure if it was 1.189 or 1.198v.
Just ran at 4.5Ghz with a bios setting of 1.28v & that may can be lower, I just popped it there from what a friend said his ran 4.6 at just as a test with mine.
Sorry this is all very new to me so I'm abit lost on some of the setting.
Is it normal for the muti to drop, say from x45 to say x40 when putting it under a load? Is there a setting I'm missing or something?
When I use the presets in bios like 4.4 it doesn't do the muti drop under load. But it gives it way more vcore than it really needs to do that clock speed.
At x46 I'm getting a lockup at boot with a post code of A3 witch is hand off to IDE X45 passes no trouble.

Asrock P67 Extreme6 (B3) Edit: bios version 1.60v came out yesterday using now, board came with 1.50v but was a really bad bios. 1.60v is some what better at OCing.
G.Skill 1600 7-8-7-20 1.35v 2x2GB

Doesn't look good to me for this chip or the motherboard. One or the other is the culpit.
