I've been rather disappointed with the matched 2 gig pair (2x1Gig) of this RAM - its standard 6400 stuff, TwinX, CAS5 version.
My setup is as follows, P5B-Deluxe, E6600 and the above RAM.
I've never known RAM NOT to like extra Vdimm before ... which seems to me an odd behaviour ...
At stock SPD speed 800 MHz, 5-5-5-15 - 1.9 VDimm is fine, Orthos stable for hours, but if I increase the Vdimm to 1.95V, won't last more than 3 minutes in Orthos, and above 1.95V, 2.0V, 2.05V, or 2.1V - won't last for more than 40 seconds ....
if I overclock slightly - up to 840MHz, 5-5-5-15 or even 18, 1.9V Vdimm is not enough, but 1.95V then suddenly becomes OK, but again, anything over that is stable for less than 3 minutes. Above 845 - at any voltage, completely unstable - but will boot.
I know I can't expect memory to overclock, but I've never known RAM not to like extra voltage, not enough one would of course expect it to be unstable.
Cooling is not a problem, case has 3 120mm fans, and case is large and uncluttered.
I've done some further tests - to see if I could work out what is going on.
If I set memory to 800 MHz, SPD settings, VDimm to 2.1V - then run Mem Test in dos - it doesn't get past test 5 without errors, test 5 gives 370 errors itself.
If I set memory to same settings, but VDimm to 1.9V - Mem Test passes fine.
I thought these modules were meant to take 2.1V without any problems ? Any idea to why it can't ?
thanks, Mark.
