REALLY bad Q6600 G0 overclock. Help?!

[MR.B]

Got my G0 today, and no matter what i do it will not go over 2.69GHz (299x9 / 1199 FSB) If i increase the FSB by 1MHz more, to 1200MHz, it will not boot windows Vista or XP. Sometimes the system posts ok, but as it goes to load windows it restarts.

I've tried:
Loads of diff FSB speeds from 1200 - 1610MHz. None of them will work, anything under 1200MHz works though.
CPU voltages all the way up to 1.5v
Increasing chipset voltages, RAM and FSB voltages.
Lowering RAM speed to just 650MHz with 5-5-5 timings.
Disabling C1E.
Lowering multiplier to 8x or 7x.

Nothing works! is there anything else i can try?

BUT i think it's my board, as it's a EVGA 680i SLI mobo, and i got it not too long after it came out, now i remember back then some 680i boards had crap capacitors or something so you could not go over 300x9 with Quads, but they fixed it later with newer board revisions. I'm guessing my board is one of these?? If it is, do ALL new 680i mobo's now have this problem fixed? 'cause i'll get a newer EVGA one if they have.

Will you be getting X38 boards in anytime soon Gibbo? I dont know when they come out... just know it's not too far away.
And whats the best P35 board for overclocking quads?

 

[MR.B]

have you tryed 410+ FSB? with low 6x multiplayer?

i heard there's a FSB hole with the earlier EVGA 680i boards

Just tried 420, and 440 FSB with 6x multi, will post but again wont load windows. It deff seems to be the mobo, it's completely stable at 299x9, but at 300x9 and anything over it just either wont post or load windows.

I was looking at the Asus Blitz Formula board (P35), is this one of the best for overclocking?

Just ordered one as not expecting my P5WDH to be up to much with new G0......will advise !

Cheers mate! dont forget

I used to have a P5WDH before this EVGA 680i, no way as good as the EVGA for OCing dual cores... shame my revision of the board sucks for Quads.
