hey yall
first things first http://valid.canardpc.com/show_oc.php?id=599048 , i have got to 4.5ghz on my cpu for our hwbot team but i cannot get any higher as the cpu voltage option maxes out at 1.5v on my mobo (asus p5q se/r). are there any moded bios's i can download to change this or any hardmods.
cheers
phil

oh look i here that most dreadfull of words "BUMP"

I don't think u'll get much higher than that, it's already hell lot of OC for this CPU

.

There might be some modded BIOS if you search around but I guess the other option (if you really need it ) will be to change for new mobo, from my experience, the DFI mobos had quite higher possible volts on em ( 1.1-1.6 and then even 1.8 jump for extreme OC if i remember well ) but you will have to check on that.

Anyways, nice OC.

Fix your RAM timings tho, 6-6-6-18 for just 900mhz is bad

. My old geils could pull 890mhz with 4-4-4-12.

ive tried but my ram just doesnt seem to like tighter timings than that when its oc'ed

Oh ye you got the PC6400 corsairs, I didn't have very good experience with them either.
Did you try lowering them bit by bit ? Like move from 6-6-6-18 to 6-6-6-17 > boots? > 6-6-6-16 > 5-6-6-16 etc?

Also you can try doing it the other way and squeezing the max MHZ on the timings that you have, if you can increase the RAM multiplier in example and some extra Mhz on the timings you got, like 950-1000 with 6-6-6-18, that would always give few % boost and everything counts in benchies
