You Vcore is already pretty low ( especially compared to the typos in my last post. It should have read 1.15v and 1.18v ), so I don't think you'll be able to squeeze much more out of it.

Yikes! My temps drop back to about 30C when not folding. I have to agree with Matt though (hardware expert that I am...) - does sound like your HS needs re-seated.

That's my next job when I can find the time.

You need an I7, they love the heat.
The cores on these things can sit on 85c with no long term problems. Im running 2x SMP clients on separate cores (with HT on) both cores are sitting at 43c atm. However for the higher core temps they do seem to have a low T-Case temp of 65c.
Im also currently OCed from 3.06ghz to 3.96ghz Vcore@ 1.33v

If you have the money get an I7-920 D0 stepping if your lucky.

Unfortunately I had to scrape the bottom of the barrel to get the E8400.

Karlos, where did you get that bit of info? At 85c you would be getting close to the thermal throttling trigger point and that's too high for daily use. The Tj Max on the I7 is 100c, same as the E8400. For daily running you should really maintain a delta to Tj Max of 30c which equates to a safe max core temp of 70c on the E8xxx and I7. However lower is obviously better and most hardware geeks will tell you to keep it under 60c. I agree as a blanket rule of thumb, but I believe "30c below Tj Max" to be a more finite rule with newer CPUs that have the DTS built in to the core.

I have the article link somewhere, they have successfully tested an I7-920 under full-load at 100c. Ran error free without throttling, however they recommend not running at 100c more at 80c. So you where right there 80c is max roughly but it depends on the quality of the wafer that the CPU is made on. There can be a +/- 10c-15c difference in max temp
with each CPU.

While that's an interesting article, I'm a bit skeptical of their test results. According to the chart posted in the article, they bench marked the CPU for 7 minutes at 100c. I don't think you could find one person on the Hardware team that would consider that a successful test. For good solid data, they would need to test multiple CPUs for hours/days at high temps, not minutes. He may be correct, but there is not enough data there to back up his statements.

Aus_Karlos

True but no one in their right mind would want to run a CPU at 100c. Over at extremeoverclocking[dot]com many I7 owners say 85c is the max anyone should run their i7's on a 24/7 basis. And i have to agree with them.

As a hardware team member, I could not in good conscious recommend anyone run any processor @ 85c on a daily basis....not even a Prescott. So I will stick to the delta of 30c to Tj Max. and we'll just have to agree to disagree on the matter.

(After this conversation, I may have to build an I7 system now just to see how much abuse it will handle before it dies,......once the prices come down a bit more:)
