Q6600 at 3.3. Bit more help to push it further plz

Deyvy · 23 Jun 2008 at 16:22

I'm new to overclocking but have managed to get my clock stable a 3.3 (9x368) Just through changing the FSB. Anything above that I start to get errors. I'm got it running at 1.45v. Seems to idle at 30 degrees, and under load its steady at 50.

I'm only using the uguru software at the moment, mainly because its easy for me being a beginner.

I just need a bit of advice of how to get to 3.6, I would like 3.6 but even 3.4 would be happy at that..

To get any higher would I have to up the northbridge and southbridge voltages? And what would be the best way to do that, increase by a notch? then test?

Yeah it's mostly trial and error.

Raise one, test it and react to its result. If it makes things better then good. But there's no difference or if it makes things worse, then put it back and try something else.

Do you raise both north and south at the same time?

Cob · 23 Jun 2008 at 16:39

I wouldn't really worry about the SB voltage. The NB, FSB Term/VTT and PLL are the important ones along with the CPU voltage.

But always change only one setting at a time so that you know which one is making the difference.

And try to clock in the BIOS. It's so much better than clocking with software.

MCH = northbridge voltage.

Whats CPU VTT and ICH then?

Thanks for the help btw..

CPU VTT is FSB Termination, and ICH is the southbridge (providing that it starts at about 1.0v-1.1v). There may be another ICH voltage that starts at 1.5v and that will be the PCI-E voltage.

Managed to get it stable at 3.4 (9x380) Ran Prime95 all night no errors. Was a little worried it may blow up in the middle of the night or something..Running at 50-52 degrees.

Used to get errors as soon as I ran everest stability test on anything over 368. Upping the CPU VTT and Northbridge has stopped that.

Whats a high temp for the PWM Phase? Highest temp was on one of them at about 80 degrees, is that normal? Noticed that increased when I increased the NB and VTT volts.. Uguru has got the warning set for PWM at 110 degrees..

The PWM's are designed to run at well over 100c. They'll always be the hottest component by far.
