    Re: Overclocking Q6600

    Q6600 is warranted up to 1.5v I'm pretty sure, Intel spec finder says that the VID can range from 0.85v - 1.5v indicating that a chip could be supplied with its stock voltage as high as 1.5v

    Oh also set your memory timings to 5-5-5-15 to begin with while overclocking this will keep the stability higher you can lower them once your CPU overclock is stable, remember you want to test one thing at a time rather than changing 5 things then trying to work out what has happened!

    Finally from Matty's photos the FSB is called "External Clock"

    1.5v?! . surely not..

    that's a good point. you could even rule the RAM completely out of your problems and set them as high as 6-6-6-18 or something like that.

    so that means that the Q6600 is perfectly safe at up-to 1.5v? it won't damage it?
    unless you have insufficient cooling, of course..

    Well yeah.. as long as you don't let the temperatures go outside of the limits too. People run their Q6600's at the usual 3.6GHz on 1.45-1.35v or if they're lucky even lower. 1.5v and over is the danger limit for 65nm.

    Re: Overclocking Q6600

    Yep thats right the 45nm quads are fine up to 1.3625v though so be aware that for the big overclocks you almost certainly move outside the "safe" voltage range.

    Unless you're lucky
    Didn't get lucky on a Q6600 but did on the Q9550

    Re: Overclocking Q6600

    Well heres my plan...

    Set my timings to 5-5-5 15 (?)
    Then make a small jump on the FSB from 266 - 300

    then reboot and test using the Intel Burn Thing

    Yep don't forget to set the memory divider to 1:1 as well!

    Try 1.25v, also do a prime after IBT. When I was overclocking mine I tried IBT for 6 hours while I slept and woke up to find it passed! Awesome, now when I tried Prime95 it would fail on the last core at 12 minutes each time, I just raised the voltage one small notch and all was fine after that. But if you don't think of Prime as a superior or decent tool to test then use IBT.

    1.25v was stable at 3GHz for me. Whats the normal VID for these CPU's?

    Well ill try above, without messing with the 1.25 increase...then see what its like

    Re: Overclocking Q6600

    I've been running my Q6600 at 1.43v for over a year and it's on a lot and occasionally runs for days on end but it is water cooled. It even ran for over 6 months with a poorly fitted waterblock (I didn't realize at the time). The large variance in code temperatures and the high readings (65C under load) probably should've tipped me off but it never crashed so didn't care. The Q6600's are by no means indestructible but are pretty hardy unless you do really stupid things to them. BTW, after re-seating the waterblock properly it barely creeps over 50C on load and core temperatures are within a few degrees of each other . Under 30C on idle (Coretemp 0.99 readings).

    To get a more accurate temperature readout you should use coretemp. On my abit x38 quad the uGuru software is usually a good 20c out!

    Re: Overclocking Q6600

    Well I've got to format today, PC problems, plus its not been done in a very long time so it needs it.

    When I am back up and running, I will probably give it a go, just a little jump from 266 FSB to 300FSB

    With CIE off and RAM to 1.1.

    Thanks

    Re: Overclocking Q6600

    Hi. Newbie member here.

    Ive just got a new G0 Q6600 but overclocking is really bad. I cant even get it running stable at 3Ghz (9x333) with |Vcore at 1.45V.

    Motherboard is asus p5b-e but I know thats ok as my previous E6550 clocked effortlessly at very low vcores. Also know my Ram OCZ platinum is good for it.

    Basically as soon as the clock approcahes 333 everything goes a bit feet up. Even tried lower multipliers but no good.

    Some research leads me to believe a may have been unlucky in getting a Q6600 with bad VID ( 1.325v)so the Vcore is high to start with.

    Not happy reading about people with 3.6Ghz overlcocks. Wish I'd kept my E6550 as was faster at 3.2Ghz and that also gave my a nice 1:1 RAm timing.

    Anyone else out there struggling?

    Probably your VID..
    I'll check my VID on mine, I could do 3.6 with 1.425v iirc.

    1.2875v VID
