Hi there all, I was wondering if some of you tech heads out there could possibly check my overclock set up... its stable at the moment but my idle temps are around the 50c mark and it got me thinking maybe I can still tweak to improve the temps:)
Can anyone note anything that maybe not quite right ?

Get QPI off Auto and set it manually, start at 1.3v, increase if unstable, decrease if stable and find the lowest point.

Its probably set quite high on Auto..

If unstable push one notch up on the qpi/vtt until you getting a stable!

Disabling speedstep could also lead to a high idle temp. During speedstep the CPU will go to lower speeds, resulting in less power used, meaning a lower temperature. When more CPU power is needed it will clock it self back up to your overclock.

re:

Everything appears to now be stable with VCore at 1.3 and QPI / VTT at 1.27

Can I try enabling the speed step? can I just enable it and all will be fine or do you have to change a few other settings from what I have got to get it to work etc????

For a 4GHz clock you shouldn't need to tweak the CPU/pci clock drives. You tried them at their default values?

Also, vcore could possibly be lowered. Try knocking it it down one notch at a time and do a quick LINX or IBT test for stability. As soon as unstable or BSOD turn it back up a notch and do a prime blend run for final confirmation of stability.

What are your current load temps btw?

testing idle means nothing at all, if u are overclocking u need to be testing loaded temps and if its stable or not.

I can have my cpu sitting at 4.7ghz+ being idle, but will fail in a sec underload.

So forgot idle temps the mean nothing, its load temps that matter, plus if its stable or not.

It's the load temps that matter, because of the potential damage done by overheating. ;) I suspect you will be fine however with that H-70. The chip needs to be kept ideally under 80, 85 max under load if you are feeling brave.

Leave the QPI as is unless you loosen the memory latencies or lower the frequency.

I'd be interested to hear how you get on with stress testing and temp monitoring. I'd like to see that H-70 in action!

re:

Managed to lower the Vcore to 1.28750 with te QPI /Vtt still at 1.295

I do not want to run a long test just at the moment and tried the Intelburn program someone suggested at the start of the this topic.
Its a short test where I run it on standard at first where it pass fine then I tried it on high and it passed fine.

Is this program any good to get a rough idea?

Or is it the long running benchmark programs thats only worth bothering with?

Cheers

What i do is, if a given overclock can pass 10 runs of IBT with max settings, its stable to me, i then go about doing my normal stuff, to me the normal stuff is my long testing phase, if at that point i have issues, i up the vcore a notch, and carry on.

Some people will say X amount of hours for this or that, but thats all well and good, but as iv posted on here before, iv been 24hr+ prime stable, and had errors when Folding/Encoding. So to me stress testing programs are ok to see if its kinda stable for that, but i would allways suggest doing the normal day to day stuff, and keep an eye on things.

Run IBT for 20 runs at maximum stress level for a 'quick' indicator. Should take 1-1 1/2 hr max.

This shoudl be followed up by an 8hr + prime test for complete stability as bulldog has already said.

What are your load temps under IBT?
