i have my q6600 at 3.0 mhz and i am running volts at 1.23 the minimum .

question is it safe to run at that or do i run it at stock volts ?

mb is a x38 dq6

thanks for reading

Why dont you try running P95 stress test and stress all 4 cores using Small FFT's. If you can run it that way for 6hrs or more with no errors then your CPU is stable.

Just remember to Select SMALL FFT's test. Let it run over night.

never tryed that (yet) . and had it running like this for 4 weeks and been ok on crash

just want to no if undervolt is safe

Anytime you have your CPU overclocked its of the up most importance to stress test the CPU to make sure you are stable.

Just because you do not crash when surfing the net etc.... does not mean you have a stable overclock, you also risk the chance of corrupting your whole OS....do you really want that?

i have windows orthos thats the same i have run that . also been playing crisis and cod4 alot sytem was ok

Does it stress all 4 cores? im pretty sure it only stresses two.

The already mentioned link to Prime95 download and run it. To answer your original question there is no harm in under volting your processor if it will run error free when using the Prime95 at that voltage.

Well said ;)

The problem I see so often is that people think they have properly stress tested their overclocked CPU's when in fact the majority really dont know how to properly do it, a lot of people end up only stressing 2 of 4 cores, or they do not run the Specified SMALL FFT's test but instead run LARGE FFT's which is mean to stress test the ram. lol.

Use the Link that I posted for P95, it stresses all 4 cores but you must make sure to select SMALL FFT's for testing. Also let it run for 6 or more hrs error free. If you can do that you are good!

I ran small FFTs on this overclock overnight and the temps never went over 52 degrees on a single core according to coretemp, and 30 something according to speedfan. Im guessing coretemp is the more accurate based on that.

DO I RUN THE PRIME 95 ON DEFAULT or click the top one then run it?

Go to Options -> Torture test

Then make sure it looks like this

yea thanks got that and that will strees all cores?

Yup google "coretemp", which will show you the temperature difference, I'd consider leaving CPU-Z open as well to see if you get any voltage droop (Happens with some ABIT motherboards), and can be quite dangerous.

Press Ctrl+Alt+Delete to open your Task Manager and click on the 'Performance' tab to see if it's using all 4 cores.

Yes, it will stress all 4 cores to 100% load.

I have a Q6600 B3 that is undervolted by .5 from the CPU's base, even though it is OC'ed to 3.0GHz, I could go higher, but by undervolting, I am manging heat and noise with added perormance.

i used to do the same (have a b3 q6600), till gears of war and crysis came along.

both used to freeze randomly, with audio looping in the background. though event viewer showed nvidia driver errors, upping the voltage to Vid solved the problem.

I couldnt run OCCT 30 min test either, but everything else ran fine.

how mutch more did you up the volts? also i have had one crash in crisis . with the nvidia driver but since i went too 169.25 it has been ok . i may up the volts

Do not stress-test your CPU with games; use only Orthos or Prime95 and make sure that you're stressing all cores. Crysis is not even quad-core optimized. Most games aren't.

found this link and looks good thats the volts i am running my q6600 at says on link is most stable

tell me wot you think

So are you just gonna keep on ignoring the advice that I and some others have given you about running Prime 95 to check for stability or what?
