Here are the specs from my BIOS

CPU
Ratio 19.0
BCLK 200
PCIE Freq 100
DRAM Freq 1603
UCLK Freq 3208
QPI Link 7218 MT/S

CPU Voltage 1.225
PPL 1.88
QPI/Dram 1.325
IOH Voltage 1.10
IOH PCIE 1.50
ICH Voltage 1.20
ICH PCIE 1.50
Dram Voltage 1.64

And here is a screen shot of the info running..

I would really like to get to the 4.0 mark but even with upping my core voltage to say 1.4 doesnt work because the processor temps get too high...

It's upward locked. You can adjust it between something like 12 and 20. The 940 can be adjusted from 12 to 22, and the 965 can be adjusted from 12 to 64, or something ridiculous like that.

Nice.

You said your results were "stable", but from what I could tell on your screenshot, you're only at idle. Is that right, or were you running the CPUs hard and got those temps? Not a challenge or anything, I'm just learning here as I'm new to overclocking.

The reason I ask is that I got up to 3.8 with a 190clk x 20mult, stable doing normal non-stress stuff. .... But was unstable when CPUs maxed out, only got about six minutes into prime95 before it died.

Currently I'm at 3.4 @ 170x20, but with prime95, temps stabilize very hot ~80. Hoping the temps won't be so high with real-world intense work like video encoding, but haven't tried yet.

I wouldn't worry about real-world apps even approaching prime95 temps. I peaked a bit over 80 on a 13 hour prime95 run (high ambient temps by the time it was done) and have NEVER seen my i7 go over 57ish on any core with acceptable ambient temps. The thing never even breaks a sweat with anything I throw at it. (long gaming sessions...crysis, L4D, WoW etc.)
