EDIT: when i first got 3.82 stable i had the fsb at 1.45v and spp at 1.5v. after messing with the gtlref lanes i was able to lower the fsb to 1.35v but i still run the spp at 1.5v. nvidia chipset boards need lots of juice to stabalize high clocks.
Do you really think i need that much juice when im only trying 3.2Ghz? Could it be that there is a uber-fsb hole and i should try 3.6 (i only tried as high as 3.4 and that was before i was messing with voltages). Did you get stable at a lower speed with any lower settings?

Also, i would really like to avoid reinstalling windows so i was wondering what are the chances this is my problem?

EDIT: just tried 1.45v fsb and spp at 1.5v with the vcore giving me 1.30 (acutally set to 1.325 or something close to that). It booted into windows just like usual and then froze like usual. I then went and set the voltages to a lower setting (vcore 1.2625v fsb 1.25v and spp at 1.4v), it lasted just as long as it did with the voltages being higher. I dont want to give up on OCing this since it will be a while before i get my i7 build and i would like the performance gains but i have tried everything and not a damn thing has helped...

I've got my q9550 stable at 3.4ghz with these setting: vcore: 1.235 vtt: 1.20 spp: 1.45 nf200: 1.20 and the gtlvrefs at +65mv my memory is set at 800 4-4-4-12 2t @ 1.9v. If you're only trying for a 3.4 OC you shouldn't need more than a vcore of 1.25.

I'm not completely convinced you are giving it enough vcore. While in theory, you should not have to run that much to the chip, every chip is different. As long as your temps are staying reasonable, crank the vcore up.

Heh, it's prbly want me much differnece. I played a little with 3 cores and I don't even know if I could get 3.7 stable. Did a few boots try to push 4.0 with only 2 cores. Posts with 1.54v. I could get it to load windows, but crashed 3 secs into IBT. Might be able to squeeze 3.8ghz out of 2 cores, but it's just not worth it.

Temps are holding me back. Once this thing hits 70C stability is ify. I really need another 240 rad so I can get this thing on water.

I use to have the same processor and motherboard, but I sold my q9400 and got a q9550 and the difference is unbelievable. Like you, I couldn't get past 3.2ghz on the q9400. I'm now stable at 3.9ghz on my new q9550. I would seriously consider upgrading your cpu, that is most likely that cause of your bad oc. Make sure to get E0 stepping if you get the 9550.

Alright, here's the juice on my OC:
Q9550 @ 4.03GHz vcore-1.27 load fsb-1.35v spp-1.4 nf200-1.2v All 4 lanes were left in Manual @ 0mV (I'll tweak later to lower fsb v's). Temps as follows Highest core @33C idle/ 52C load NB @41 to 44C. I used a modded Antec spot cooler instead of the stock (Original TIM , I forgot when installing...lol). I unscrewed the fan from the support flex stick & zip-tied it on the top of the NB cooler to PULL (high speed, not loud) thru air (pull>push). I also cut off the blue LEDs from the fan. I only wanted UVs. To help anyone else out the leds are on the exhaust side of the fan.

Great OC but amazing temps!...

What's your ambient?

22C or about 70F
