Q6600 680i

So I upgraded from my E6600 which I had at 3.6ghz for months to a Q6600 G0. Everyone is talking about the G0s going so high on the 680i but I can't get past 3ghz. I tried every combination of fsb speeds and voltages with a max vcore up to 1.63 (set to 1.68 got 1.63). I had the fsb up to 1.5, spp up to 1.55, mcp up to 1.6 and the spp to mcp voltage up to 1.5---every combination between stock and up to these voltages has been tried. I also tried all of those on the p31,p30, and p28 bios. all of the cpu features have been disabled like they should when ocing. The highest clock I can boot into windows with is 3.1ghz. I read about the fsb hole issue so I tried 20mhz increments and found no sweet spot.

Whats strange is I can post at 4.1ghz (I didn't try any higher) and everything below but at best I can only get to a bsod on boot, most of the time its an instant reboot right when the os should start loading. I tried a bootable linux distro to see if maybe it was vista but linux crashes as well.

system specs:

EVGA 680i rev. A2
4 gigs ocz sli ram- I have tried various ratios linked and synced and unlinked and unsynced this is the same 4 gigs of ram that I had my E6600 up to 3.6ghz.
Q6600 G0 stepping- water cooled
water cooled northbridge

680i sucks for oc's i found out the hard way, I can only get 3.2ghz on mine, but with my p35 i could get 3.7+, im going back to my p35....but gl
 
WOW! that's really bad news to hear, especially considering I just put the dangerden water block on the nb. I'd really like to know how so many people are getting insane overclocks with the q6600s on this board:confused:
 
I also have a 680 board with liquid cooling on the CPU, NB, SB, and the 8800GTX card. The highest I was able to OC the Q6600 (stable) so far is 2.92 (it locks @ 3.0). And strangely, I've been able to POST up to 3.8, but can't find the sweet spot either.

It seems as if the 680 chipset doesn't OC very well, at least according to many experts on this forum, and from personal experience thus far. My hope is to get this Q6600 locked @ 3.4 or 3.6, but insofar, it seems like a futile exercise. I've been able to POST @ many speeds and various vcores. None boots. I actually did get ONE boot into Vista 64 @ 3.42, however, the VGA driver didn't come up, neither did the sound, each program @ startup would crash and/or Vista would report that it was trying to read an area of memory reserved for another function, id est, no success.

I'll keep trying, until it works or drives me insane, at which point I will be maxed out @ 2.92.
 
I think I'll end up getting an X38 board cuz I put a lot of money in to water cooling this rig between the case and other components, I won't be satisfied with a clock under 3.8ghz.
 
my Q6600 @ 3ghz wasn't hard to get at on a 680i. I haven't tried past that, but it wasn't to bad. I have seen a lot past 3ghz, so I'm not sure why your chip isn't getting there.

or wait 4 the X48 :rolleyes:
 
Are you running at least the p30 bios if not even the p31? If i recall correctly they fixed most of the problems with OCing quads with either p30/p31. Check out the forums. One of them had it. Then the next one was released (p31 i think) that actually broke it again. Read the p30/p31 threads on evga's community boards! :)
 
I am running a 680i, with P30 bios, and I am very happy with the results so I am not going to chance it and upgrade to P31.

vcore = 1.4000v, @ 3.3GHz.

I had it at 3.6GHz but with vcore=1.5V. Did a 3mark06, smiled and went back down to 1.4 until finding the highest FSB at 1.4v.

I find it amazing that so many people are having so many problems with the 680i. I guess I have to thank the mobo Gods cause this is my 1st build, and if I had those problems I would have been very discouraged.

Good luck.
 
Same. I'm still using p30 as i read soso things about the p31 as well. ;)
