***The Official Q6600 Overclocking Thread ***

New mobo is definatly arriving tomorrow. So well shall see what that can do.

Im going to RMA the Abit and if this new mobo isnt as good im going to buy the Crayola board but ill hopefully get some more Ultras before I do so they can go in the motherboard thats coming tomorrow.

Should hopefully get some good comparisions tomorrow and friday though.
 
Random post from compared to you guys but I lurk here a lot ....

Best I have managed is 3.33ghz 5 hours tested under prime95 ver 25.4 top temp was 60C. Screenshot to follow.

Anything over that and I failed straight away although could boot into os.

Could be a memory vaoltage issue although was pretty happy with temps.

Oh ignore sig the q6600 was my upgrade :)
 
There's still life in the B3's yet

Water cooled running Seti@Home

Got mine 9 hours Prime stable now, 3393MHz @ ~1.45v, though with a max temp of 78c (on cores 0+1 - 1+2 are up to 6c less).

That was with the memory (Crucial Balistix) @ 452MHz/5-5-5-18. I've had the mem @ 500+ on a 2:3 divider with a lower cpu speed, but only had it priming for 30 minutes.

I've considered trying water in the past, but never got round to it - maybe it's getting time for a dabble. The PC is set up in the loft where it could easily get 5c warmer if summer ever comes back, so a bit more headroom might be usefull ;)
 
well i'm currently priming my B3 at 3.4ghz.

Its just fully passed a 12 hour stint of prime at 3ghz with just 3 uber quiet fans cooling my water setup so if all else fails i'll be well happy with that. I'd prefer silence than another 200/400mhz

A tip though for anyone a bit stuck.. dont know whether its just mine but the NB stock cooler on the gigabyte DSR3 is pap when you start clocking. Would only give me 2 minutes of prime at 3.4ghz and around 5 hours at 3ghz until i pointed a bit of air flow at it. And it is only a bit of airflow.. an old modded stealth fan. The thing is now cool to touch after a hour on prime. Without the airflow, its untouchable so there is a huge difference.

Now then, with my current prime session, the 3.4ghz is coming from an 8x427 fsb. This allows my memory, ballisix 8500, to run at 1068 or summit using one of the multipliers/dividers whatever they are in the bios. Is the the right route to take, or am I best going to the 9x multiplier with a lower FSB?

This intel malarky is a bit foriegn to my AMD blood :)

Oh yeah, and my voltage is at 1.376 at the moment according to CPU-z. Much higher in the bios though?

Cheers

I would say you have a much better chip than my old B3. I was pumping over 1.5v through mine to get to 3.4GHz (im on water) so I guess you have a little head room! ;)

Just keep an eye on the temps. Mine used to get into the high 70's but I had a carp chip. :p

Although im getting a GO tomorrow fingers crossed. :D
 
Swapped the motherboard from an Asus Blitz to P5K Premium. Lapped the Ultra Extreme, gained a few degrees (hardly worth the effort imo) for the same vcore after droop. The Blitz droops more and its NB is a bit hotter.
