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. My temps didnt go above 73 c which I thought was pretty good. I still need to optimize the vcore. The 4.2 has got my interest and I think it is possible but will run like this for a while and see how it goes. Ran your tune flight senario and can more or less maintain 30 fps with Very Dense autogen and max scenery detail and 6% cars and 59 AI (ultimate traffic) with low ground vehicles at airport. Very very very happy with that! Came from a Pentium D 805 so hense my excitement. Do you see anything I can try to help go higher or am I maxed out.

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

opppsss LOL

I have 4 i7 coversations on my screen right now.. you are # 2

sorry

OK.. same deal, leave it.. you still need special cooling to go any further but it is possible, much easier than a 920 but it is pushing things.

QPI/DRAM limits are the same though and yes, the higher the clock the higher QPI/DRAM must go

Congrats on 4Ghz!

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

Agreed! One main thing I have noticed with this system is that when I make a setting change in FSX I can really see the benefit or the neg side of the change real easy. On my old system it was so taxed that I couldnt tell if the changes really made a diff. I get the best smoothness with it locked at 30 and it has never fallen below 18 even at KLAX! I also found that my VC wants a lower bufferpool even though I have 896 mb of ram on it. When I had it set to 70000000 I got bad spikes on the screen and bad performance. Changed it to 30000000 and all is well and havent seen the spikes since. Maybe it has something to do with the fact that I have the Superclocked version of the 260. I read on EVGA site that some people are actually downclocking them to fix it but the lower bufferpool fixed it for me. Thanks for all your help, I used alot of your suggestions if not all of them and it has paid off 10 fold! See you in the skys ... Europe soon?

we are hoping within 90 days on Europe

And yes, bufferpools is tricky.. you must work the value. Sometimes it is best to just completely remove it from the config, others you can see the difference flying over large amounts of autogen trees and building

Have fun.. I am glad you went this route.. you have a lot of time now with that system and the ability to upgrade again too

What about this

Intel burn test

http://www.xtremesystems.org/forums/showthread.php?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....

its one hour and if it passes its stable enough

LP is for geeks that want bleeding edge IMHO

there is such a thing as overkill for normal system use
