Going to be overclocking my Q9550 - Is this a good chip?

If you want the best resuts from a 45nm quad on p45, youre looking at GTL tweaking, particularly when you go above 450fsb .

I had to spend about 4 hours hand tweaking the GTLREF lanes (all 4 of them) on my nForce board just to get 3.825gig stable (450FSB) lol... could probably have just upped the vcore/vtt a couple of notches instead tho.
 
Rroff, 3.825 on an nforce board is extremley impressive with a quad, what was the cooling btw, i had very little issues with my p5q deluxe/q6600 combo, i then moved to a q9550 (bit of a silly upgrade) it was actually harder to get blend stable, involved more tweaking of nb, pll and vtt as opposed to the q6600.

Coolermaster V8, with modified fan.

It boots into windows no hassle at 4+gig - all the way upto 4.25gig (500fsb) - anything above 500FSB doesn't even POST with sensible voltages - but to actually be stable at those speeds would require a lot higher voltages than I'm happy with.

Have to admit I'm quite happy with the performance increase - even coming from a Q6600 @ 3.6gig which was by no means slow - only really upgraded so I could pass on the Q6600 to someone else.

Aye my q6600 was doing 3.8ghz on 1.512 v core on air, apparently they can run upto 1.6v with good cooling, the q9550 done 3.8ghz on 1.21250, (vid of 1.200) sold it to fund my i7 rig. Trying to get another gtx 280 for sli, ideally another xfx xt 640mhz core clocked card to match my current one, but any gtx 280 would suffice if i could get one.

Aside from the lack of VRAM at super high res I can't fault my 260 SLI - comes into its own at 2048x.

My Q6600 did 4gig no hassle on a P45 board ironically... but at the time the 295GTX was twice the price of a 750i and 2x 260 combined.
 
Bah... so close to 4gig I can practically taste it... I just know it needs one more turn of the voltage dial... but already at what instinctively is max safe voltage for 24x7 use...

Still 3.825 seems rock solid, can IBT as long as I like and it never goes over 67C and passes with flying colors.
 
settle for that, even for 24/7 use all your cores are not going to run at anywhere near 100%, its a good overclock considering your nvidia nforce chipset, i remember trying to overclock my old q6600 on the 650i nforce on the p5n-e sli, was one of the few to reach 3ghz. in the end i fubared the board because i got power hungry for more :D
