Testing / comparing : Intel D975XBX2 / Asus P5B DX ***56K WARNING***

[Speederlander]

Well, after getting the new (replacement) board and overclocking it for the last few weeks, ended up with the following:

QX6700 @ 3.3 GHz, 330 (x10) FSB with 1.3625 vCore set in BIOS on air cooling.
FSB voltage is lowest possible setting in BIOS (1.2v I think).
MCH voltage is lowest possible setting in BIOS (1.5v I think).

Prime95 with all four cores running small fft gets to about 70C after 24 hours of stressing it in typical indoor temps. So far have stressed it for 24 hours of small fft and 24 hours of blend with no errors.

Memory is 4 gig Mushkin 8500.
running 4:5, 825 with timings 4/4/4/12 and vDIMM of 2v.

I suspect I can get more out of the memory if I want to push it but I don't see much need atm.

Not bad for a 24/7 air set-up.

Can't get it to high FSB and stable no matter what I do. Interestingly I booted into 401 FSB on my P5WDG2 WS Pro by mistake with the QX6700 and it posted no problem, though I am sure Windows would have been impossible.
