Q6600 oc.

We can't say, as it depends on the exact CPU you have. Some Q6600's can overclock to 4GHz+ with good cooling, while some may only be able to hit 3.6GHz for instance.
 
re.

i am more concerned about the Mobo
what things should i look for when upping the voltage
and what will pop first...
if i can get 3.5ghz i'll be more than happy concidering its a $1,200 build
 
well try for 3.2 at first, thats definitely reachable.

we cant really tell you just how far yours will go though, because none of us have your exact setup. i would just loosen the ram timings to something really conservative, and start bumping the fsb. when it gets a bit unstable turn up the v by .025V or something.
 
It depends on the individual CPU. Most Q6600 chips should do 3.2 GHz just fine. A smaller number are capable of 3.6 GHz. A few (VERY few) can hit the 4 GHz mark, but usually only with an extreme cooling solution.

I usually start with everything at default settings, and SLOWLY raise my FSB. I test stability with an hour or so of Orthos small ffts, and if it passes, I bump the FSB up another 5-10 MHz and test again. When Orthos fails, I bump the VCORE up ONE notch and try again.

Overclocking is an art, and it takes A LOT of patience. GOOD LUCK!
 
re.

thnx heaps guys...
your input has been helpfull....
i will post back in a week or so
regarding specs.. jus waiting on a few more parts.. when build is complete
lol i think this p4 is jellous.. its running quite smoothly.. i dont think it wants to be in the shed... lolz
 
i had a few sticks of ram before that wouldn't run a divider, limiting my overclock to 2.4ghz. i bought some larger sticks and pushed it to 2.7ghz. i left it at 2.66ghz even though it tested perfectly stable at 2.7ghz, just to make sure.

so.. in short, it could be any part of your computer that's limiting your overclock. right now for me, its my cpu's multiplier. my motherboard is rated at 1066mhz, and im currently running 1525mhz fsb. while that's a great overclock, my cpu could run faster with a higher multiplier.

It's the motherboard that sets the divider, not the RAM. All a divider does is determine the memory speed based on the FSB and the divider set.

BTW, my previous X38 supported bus speeds of up to 1333MHz, but I was able to push my Q6600 to 3.8GHz with a LOWER multiplier, which gave me a bus speed of around 2200MHz :)

From my experience, I've found that the limiting factor on a Q6600 is often FSB and temps.

Even with DDR2-1066 sticks my Q6600s struggle on a FSB of more than 450, probably because after I pass 3.2 GHz the required VCORE increases exponentially. For 3.2 GHz I run at 1.325v, but to push it up a mere 400 MHz I need to raise my voltage all the way up to 1.475v. Maybe I just need to invest in a DDR3 board and RAM?
