I'm using 2 sticks of Crucial PC6400 at 800MHz. Here's the setup:
Q6600 - settings 333x9
2.0G Corsair RAM DDR-2 PC6400
(2) 500G Western Digital drives (sata)
Sony DVD/CDRW (sata)
(5) 80mm case cooling fans
CPU Temps always in the 40's
First, the ABIT board has it's lowest setting on the last number, of 15. But when I set the RAM at 4-4-4-15, she won't boot. The RAM is marked right on it, 2.1V and 4,4,4,12
Is this a limitation of my board's settings? This board is brand new as of today, I RMA'd the one that was losing video and crashing all the time. Also upgraded to the GE Force 8800GT 512, over the 8600 256 that I had in the original MB that I returned.
I am running the RAM at 2.15V and the CPU at 1.3 FWIW.
Isn't that a huge overclock for a Q6600? Maybe it's not your ram. try it 5-5-5-15 or change to 667mhz for 1 to 1 ratio, or change multiplier to 8, fsb voltage?........prime95 for a few hours..................was this ever stable at 3.0 ghz?
What happens to your timings with no overclock?
You could also try one stick at a time...........one bad apple spoils the barrel.
Whichever- ram crucial 2,2v or corsair 2.1v you are 1/2 a 10th away from specs.
Hello, I have 2GB of Crucial ballistix 800mhz and they run 4 4 4 12 @ 2.2v fine, These timings and voltages have to be put in manually in bios, But be advised though because i had to RMA two sets of Crucial ballistix before i had a good pair so test one stick at a time. Whatever you do please leave the setting at 2T and not 1T.
I can run 6400 crrucial 2x1 gig kit at 1069mhz-5,5,5,15, 1.86vdimm OR 800mhz-4,4,4,12 at 1.86vdimm. 2t and all other memory settings at "auto" on ASUS P5-E. Memtest one stick at a time at a lower voltage and work up to but not over default voltage.
