I am getting ready to play around with OC my new i7 940 and see alot of people use OCCT to test the OC. I downloaded and ran it to see what it was all about and noticed that only 3 of the 4 cores show in the GUI. Real Temp 2.90 shows all 4 and all 4 a chugging along viewing them in the task manager. Am I doing something wrong or is it not 100% compatible for i7 yet?

Its still not i7 ready

They are working on a new version for i7

Use prime for the time being and I will see what the status is on other stress test software

That is the maker of OCCT and he has a temp beta out that deals with the issue... that should work for you

be sure to uninstall 2.0.1

Yep, that works! what test should I run and for how long?

the CPU OCCT 1 hour automatic test is fine

do not mess with any other test in the list.,.. its a beta program and those are new.. just the first option CPU: OCCT

In the OPTIONS click the yellow settings icon and see if the temp is set to 80c.. if it is you are ready

Click the ON button... a 1 minute pause will occur then the stress test will begin

It will crash and halt the test if there is

A: Instability

B. You hit 80c

you have to check the GRAPHS (should be in the OCCT folder in your Documents) if you crash and not sitting right there to see what the temp was when it crashed.. if it was not 80c then it was instability that caused the crash.. that would indicate Vcore most likely

If it hits 80c but was stable you either have Vcore too high or your cooling is not sufficient for the speed/vcore you are trying to run, one of the two

If cooling is not sufficient, lowering vcore is the only thing you can do and if that is unstable then you must drop BCLOCK/ or CPU speed till its stable with a lower Vcore

understand?

Well after many many tries to get to 4ghz on my 940 I finally found the missing key. I could get to 3.8 very very easy leaving everything at auto except for the vcore voltage. Then I went for the gusto and was able to get to 4.2 to post and boot into windows. Ran occt and it overheated in 2 min of testing. Then I decided to try for an evn 4ghz also with no luck untill I made the following changes.

VCORE - 1.35
CPU Mult - 21
BCLK - 193
and this one was the one I feel that made the difference QPI voltage changed to 1.31

Cant hit 4ghz with a 22x mult but 21 worked great.

OK so you are at 193 x21 = 4053MHz and under 80c tested?

Leave it

You want higher you need better cooling

You are actually lucky to get the 920 stable and under 80c @ 4GHz

QPI/DRAM .. do not exceed 1.38v unless you talk to me first

1.35-.137 is fine

940 Nick

opppsss

The only thing you could try doing to go higher with the current heatsink is lap both the processor and the heatsink to a flat shine finish down to the copper... its not an easy job if you have never done it before but it usually nets another 5-10c on temps

It voids the warranty on the processor and HS of course and there are risks


I think you should take 4GHz and enjoy it

What about this

Intel burn test

http://www.xtremesystems.org/forums/sho ... p?t=197835

it gets my Q6600 a full 6 degrees hotter than an hour of OCCT, and that's only after 3 minutes of use.

EDIT:

crashed about 10 minutes, on an OCCT auto 'stable' system.

what would be the purpose?

MSFS and other apps will never, ever heat up a system hotter than OCCT

Instead of running an hours worth of OCCT, run 10 minutes of Linpack? Might save people some time....
