LOW VCORE

Matlough · 18 Dec 2007 at 16:07

I've managed to OC my Q6600 to 2.8 quite happily (59/60C stressed using ORTHOS for over an hour)

I set a fairly low vcore of 1.256 (default on MBO was 1.55) to reduce the temps, is this too low and also will there be a problem using low vcore if everything is stable?

if you load up coretemp and look at the VID thats the stock voltage for the chip.. you should beable to get to about 3Ghz on that voltage or just a touch up

That would explain, I guess, why my temps were so high before (stock 2.4G) using the default 1.55!

Would it be a problem running vcore lower?

Not if the computer is stable at a lower vcore.

Thats what I thought, I guess the lower the better (as long as its stable)?

BTW. How long do you guys leave ORTHOS running?

Yes lower vcore = lower temps

For a Quad Core I would run Prime95, length of time is up to you... If its going to fail then it will normally within the first 30 mins or so.. but I have had Prime95 fail after 7 hours... really if it can run Prime95 for a couple of hours its going to be 99% stable for everyday use

What HSF are you using to get those speeds?

I have a Lapped CPU and Ultra 120, and a set of very loud deltas when Prime testing

Managed to get up to 3.0 Ghz now (still 55/61c stressed) and still with a vcore of 1.256!!!

May go higher, but TBH I'm quite happy with it at 3

very nice

3.2/3.4 should be possible there for you
