Hey OCS

This is my first post here but I am usually on Techsupportforum.:rolleyes:

But I feel this forum will know more about my issue I am having, My problem is I have had my computer built and working 100% stable for about 6 months now and I have managed to overclock my I7 960 to 4GHZ stable but I feel the v core and other such things may be a bit high. I essentially winged it to 4ghz and I think its producing too much heat and it may be a 'dirty' Overclock.

PC specs:

Motherboard: Asus Rampage Extreme III
CPU: Intel I7 960 @ 4GHZ (Liquid cooled)
RAM: 12GB Corsair Dominator GT @ 1926MHZ (1866 stock)
GPU: Two Nvidia geforce 480gtx in SLI (stock speeds but wouldnt mind OCing)
PSU: 1250W Enermax Revolution

As I said my old rig (q6600) was very easy to overclock but I have had no experience of I series overclocking so I am looking for some advice, check my settings make sure i am not doing anything wrong.

I would like to push it maybe a bit more to something like 4.5GHZ But my temps are:

Desktop:35 Degrees
Stress testing:67 Degrees

I hear I7's are good up to 80 degrees under load but that seems a tad to hot for me.

I saw a review of the big water kit and couldn't help but think surely that can't work. The rad looks tiny and there is nowhere for the heat to go.
I would wait for someone who knows about this stuff but I think you could get better temps with a diffrent cooling solution
 
its about right imo,seems a lot of cpu voltage though for 4ghz,your 12gb or ram wont help,much easier to oc with 6gb

80c and below is fine for those chips they run hot,max i get is 79c @4.2ghz with thermolab baram air cooler
 
vCore of 1.41V for 'only' 4GHz seems too much. Mine does 4Ghz on 1.28v and 4.2Ghz on 1.35v. Screenie in sig if interested.

Suggest you drop the vcore a notch at a time at 4GHz and stress test for stability. Once instability noted up voltage by one notch and hey presto, max o/c on min volts! ;)

PS I don't think you will be reaching 4.5Ghz on the nehalem chip unless you are very lucky...
