E8400 & 780i OC Settings - Results

[3.0charlie]

1. Run OCCT for 2 hours minimum.
2. Your chip has stuck sensors - which means that even under load, the temps never reached 42C on Core 0, and 51C on Core 1. Once the chip passes those thresholds, the sensors will record accordingly.
3. Welcome to the Forums.

Should i have them replace it or will they eventually work?

Welcome aboard!

You've probably got stuck temp sensors. Try running the Linpack test in OCCT, it pushes the CPU a little harder, or try the Intel Burn Test.

If you do get movement on the temps, they should be within 3-4 degrees at load. If they aren't, a remount is recommended for your HSF.

Intel does not accept RMA's for stuck sensors. But they will work once you push the chip past those 2 temps. Like Sugar wrote, try Linpack or IBT for higher temps (but not necessarely stability...).

Ok thanks for the help I have remounted it like 4 times now and it hasn't changed yet. With my e6750 there was a degree difference at idle but it idled at 27 and 28. I wondered why the e8400 idled higher with less volts going through it. Thanks for the tips appreciate it very much.

will try lipack now and let you know the results. Thanks

[7oPd4wG]

Ran linpack for 30 minute test wasn't sure how long that need to run Core 0 52c Core1 51c never moved. I'm baffled. Wish i knew what my nb temp was I have done the fan mod everyone suggest so nb might be getting high.

[3.0charlie]

High NB temps using an E8400, 2 sticks and 425 FSB? Nah, no problem.

[7oPd4wG]

Ok well then 1 less thig to worry about then . What you think let it run for 2 hrs on large?

[3.0charlie]

2 hours will show stability.

[7oPd4wG]

ok will let it run later gonna eat let you know how i made out. Thanks for the input and help. I appreciate it.

[7oPd4wG]

Well 2hrs completed with large data set and still temps never went above 51 or 52. Finished with no errors.. Guess the next push is 4ghz.. gonna try it at 1.3 volts first on the core. Think I should link and sync my memory or leave it at 1066 manual. some say there is more stress with manually setting the memory. I have no clue to that rumor.

[3.0charlie]

Leave it sync'ed, 1:1. Better performance usually.

[7oPd4wG]

ok synced it is. gonna give it a go

[7oPd4wG]

BSOD at 4.05ghz voltage was set at 2.56 nb at 1.29. Should i go to 3v on core and leave nb where its at? I also changed it to linked and synced. Should i turn off sli memory as well?

forgot to add multiplier is set at 9 should i set it to 8 and go with 500?
