Those are pretty nice temps for high clocks. I use to use a V8 and when I overclocked my 950 to 4Ghz it would idle at 50 which is way too high. As for load temps, it went over 90 and I thought forget it, don't want to risk damaging my expensive 950 due to overheating issues.

Can you please fill out your System Specs Here so I can see what else is in your system.

The LinX information is good, but it shows you are only using the 32-bit version (64-bit version is more stressful, but 32-bit is still good) as well as the fact that you're not using much ram (~1.5gb). If you have 6gb of ram, then you need to be using all of it for testing (which makes LinX even more stressful).

If you are running a 32-bit OS and only using 3gb of ram, then I might move over to Prime95 Small FTTs or prime95 Blend. Make sure that under the Advanced tab Round Off Checking is checked. It stress tests differently than LinX and is better for less ram/32-bit operating systems.

However, you did pass at 4.0ghz which is a great sign for initial overclocking. What temps and voltages did you use to pass that?

i used the settings to start that you gave me

i slowly got up to:

Bclk freq. :173
Cpu volt. : 1.37500
Dram bus volt. :1.65
Qpi/Dram core volt. :1.28750

he never came above 77°C

173x25=4.325ghz

77C is a still good. I would keep pushing.

With only 4gb of ram, you can get a good feel for the stability with LinX, but remember to hit All Memory and try to free up as much as you can before running LinX by killing all unnecessary proccesses.

You can also run LinX for 1 run and stop it, then double click on All Memory and it should have freed up some more.

hmm. With turbo mode it puts on the x25 to achieve 3.33ghz turbo. I guess it can't make that permanently though. Interesting.

I would definitly keep pushing.

i950 is 23 multi, 24 is +1 turbo max with all cores, 25 is +2 turbo only available with 1 core active. The 960 has 25 perma-turbo multi.

The 23 multi is best on i950, since you cant stay on 25 with all cores and the 24 multi requires 5+ notches more vcore for same mhz on mine and several others (all hwbot records with 23 multi, 24 multi maxes out quickly), kind of like the 20 multi on some i920..still dont know why other than even multis suck...not an explanation, just an observation.

The settings/volts from chickeninferno is same ones I would start with, and I OC same way, just raise bclk as he said, and mainly just increase vcore about .03v up for every 100 mhz once you get near 4 (and know one stable point), and increasing vtt as you need. leave dram v 1.65 like he has you at...but use 23 multi, ie turn turbo off. With i960, where 25 is available, I would definitely use 25 multi.

Hmm.. Looks like you've just maxed out your Coolermaster.

I wouldn't run the stress test at 93C. You could try prime95. It might give you better temps, but I haven't noticed much of a difference temps wise between the two on the i7's
