I'm running 3.8GHz (BCLK=190 x20, vCore 1.32) on the i7 920 on Asus P6T. No sign of failure after 6h of 8xORTHOS.
But I have a hard time figuring out if my temperatures are OK. I have probably read about different forum threads this w-e, very hard to get a definitive answer.
How do people typically measure 'load' temperature ? I see in 75% of the posts to use Prime95.
If I load 1 instance of Prime95, it only gets to anywhere between 53% and 67% cpu utilisation, with temps as follow:
(using lapped TRUE120 with 2x 44CFM fans in push-pull)
Mobo: 45c, CPU: 47c, CPU0: 58c, CPU1: 58c, CPU2: 56c, CPU3: 56c
That seems to be in line with what the majority is getting (30-40c idle, 50-60c load).
But if I load 8 instances of ORTHOS, the story is very different. Then I get truly 100% utilization (on all 8 cores, i.e. 4 cores w/ HT)
Then the temps go much much higher:
Mobo: 46c, CPU: 78c, CPU0: 88c, CPU1: 88c, CPU2: 85c, CPU3: 85c
This is measures with Everest, CoreTemp and RealTemp. They are all within 1c of each other.
SpeedTemp reports much lower temps (same load w 8xORTHOS):
Mobo: 46c, CPU: 78c, CPU0: 72c, CPU1: 69c, CPU2: 68c, CPU3: 60c
1. What does the majority consider 'load' : 1 x Prime95 (53-67%cpu), or 8 x ORTHOS (100%cpu) ?
2. Am I correct to trust Everest+CoreTemp+RealTemp since they yield [pretty much] the same numbers ?
3. The normal/nominal operating temp for i7 is 67.5c -- is that for the CPU, or for each core (CPU0,1,2,3) ?
4. Is it a bad thing to get 88c on a full 100% load ? Such load in real life is very unlikely, but is it bad ?
