Q6600 Best Possible Overclock

I happen to be thinking of overclocking my q6600 after all these years and have same P35 mobo and artic freezer 7 pro, so will post how it goes.

I'd also like some advice on temps.

With an artic cooling freezer 7 pro:
At the moment 2.4GHz no o/c it idles between 35-45degC.
Full stress test it goes up to 60degC.

Does that sound right as 60 seems little high to me.
It was first time I used a non-stock cooler so not entirely sure how good a job I did seating it, amount of thermal paste etc. Could be rubbish job tbh :)

Assuming I can get o/c running, what is max temperature under toture test I should allow?

OK bumped to 2.6 for first test - voltage kept at 1.25 - and is hitting 62 on stress test already. (although it was hitting 60 at stock so...)

not sure why temps so high (especially as is rev G0)
:(

62C is nothing to worry about. Got my q6700 at 3.75ghz on about 1.45V and it idles at about 40-45C and gets to abot 70C on CPU intensive gaming or a little more on Prime95. Ramped up to more like 80C on Linpack so I just stopped messing about with Linpack. Never had a problem since first getting the OC stable.

what stress test are you using? have you got some airflow through your case?

edit- to answer about max temps- some people would say about 90C if its not 24/7, personally I'm happy to let mine run at 70C for heavy work or 80C for testing but would not go above that for too long. The answer really though depends on how happy you are running it hot- they are tough CPU's and if you're overclocking it to get a bit more from it before upgrading some time soon I'd be happier with a higher temp than if you need to keep it for another couple of years.

stress test I am using prime95 with the max temp option.

is antec p182 case so airflow is good although I haven't put fans up to full power yet as wife complains about the noise :)

for temps, 24/7 most of the time will be low-load. Gaming maybe a couple hours at a time. It's had a long life already (5yrs) so will be upgraded mid-future. So as long as it isn't cooked into complete death reduced lifespan not really a problem.

latest status is running 2.8 @1.25v fine.
3GHz it won't boot and resets to stock.
Could be voltage obviously but could be RAM as I have slow-ass ram.
667mhz IIRC and the P35 mobo only has 1:1 option no unlink.
So if I understand all this correct at 3GHz ram is already at max at 1:1.

I guess lowering multiplier would only make ram problem worse rather than better?
 
lowering the multiplier would need and increase in FSB for the same OC, so yes it would push the RAM higher at the same time.

Q6600 = 266FSB @ stock
@ 3ghz = 333FSB, so yeh the stock Max of DDR2 667mhz

You could check the recommended RAM voltage- it might be that the RAM can take a higher voltage enabling it work a bit faster than stock. Also, if you can manually change the RAM timings you could increase the timings (higher timing number, not higher speed and lower number) a notch to see if it is happier. Either of these options will probably only help a little though. A quick google finds people discussing the Asus P5KC's RAM divider options so I'd check again.

If you can get past the RAM issues I'd not worry about CPU voltage of 1.4v and 75C if I were in your situation. If you can't it probably wouldn't be worth upgrading the RAM now unless you can pick up some cheap second hand. I'm not sure which mobo you have now as there are a few disucssed in this thread, if it's the Asus P5KC you might be able to get some DDR3 RAM that would be suitable still for when you upgrade next but check this first.

My old q6600 would do 3.6ghz. I could get it up to 3.8ghz and into windows but not stable on temps/voltage I was happy with. That was on a Gigabyte P35 DS3R.
