I've run the system pretty much same volts at 205BLCK but I was never sure on its stability.

Wouldn't it be possible to smash the heck out of this record with a really low memory freq. and QPI? Will keep the temps down and the stability up.

Just curious, if the thermal specification for a 920 is 67.9°C then why do people let the temps get into the 80s and 90s?

In my experience mem. freq and QPI affect temps much less than CPU freq and voltage. I'd say its a 90/10 ratio if that. I have a very similar batch - 3849B028 but mine needs 1.35 V for a stable 4.2 GHz at 200 BCLK.

That's pretty much what I did. My ram was only running at 1263mhz for 210base clock. A lower QPI/DRAM voltage didn't really seem to affect temperatures much at all.

Thermal Specification is actually the temperature at the center of the IHS and not the cores. The cores generally run 10C lower than the center of the IHS so you would have to be at 77.9C on the cores before you would reach the thermal specification. Even then Intel doesn't say that you will ruin your chip there. They say you could ruin the chip basically when you disable thermal management and allow the chip to go past its saftey features (PROCHOT# and THERMTRIP#) which are close to 100C.

Fairly sure once the Cores hit 100 each, then the CPU temp will be around 70. What brings me to believe that are a few things.

1. When I was benching the system, as you saw the Core Temps were around 72-78 on load. Looking at the ASUS LCD Poster, the CPU temp readout never rose above 60.

2. This:



Roughly 30C on the CPU but 42.5 on the cores.
42.5 / 30 = 1.467
1.467 x 70 (Approx Max Thermal Spec) = 99.167C per Core.

Therefore anything under 100 per core should be safe.

I have a lot of voltage to give.

However, I will say that just adding to voltages, seems to be even less appropriate, than for the previous generation of cpus and boards, from what I read.

I7 is still a wilderness, as far as I am concerned.

Lately I have been getting LinX errors 5-6 hours into it. So frustrating trying to figure out the problem when it takes 6 hours each try and LinX makes your computer unusable while it's working.
