Asus p5ad2-e and corsair xms2 issue ?

[skipio]

Xassius, you may be right on that although i am not sure how low one can push the latencies even at 400. The lowest i've seen is 3-3-3-8-3 at 400 and the corsair should do 4-4-4-12-4 at 600 and 667. Sure the latencies are lower at 400, but they memory speed is also faster. Will have to read around do some tests on that.

However apart from the performane issue there is the validation issue, i.e. Asus sais p5ad2-e does 600 (3:2) with corsair xms2 5400c4, corsair sais the memory is good enough for 667 so why is my system not capable of doing this? Might there be something wrong with the memory (although i tested it at 533 (3:4) with memtest86) or maybe there is something wrong with the board? or?

Wierd, there is noone around with orsair or any other memory that can simply switch his p5ad2-e memory divider to 600 (3:2), confirm with cpuz the memory setting and let me know if it works?!

Did you set vDimm to 1.9Volts? (I give them 2.1V 24/7, they don't run hot...
If not, do that and try again...
No problem whatsoever with the non-pro version of your sticks...
@DDR533 latency settings: 3-3-2-8-4
(on P5AD2 Premium)
@DDR600 latency settings: 4-4-3-11-4

I have set the memory to 1.9V, i also tried 1.95. I am using 4-4-4-12-4 which is the memory timings the 5400C PRO modules should work fine at 667 and have also tried 'by SPD'. But whenver the 600 (3:2) option is used cpuz reports 400 (1:1) and in the SPD section it always reports 4-5-5-15. The wierd think is that according ot the asus QVL for memory on the p5ad2-e, the 5400C Pro is validated at 600 while the non Pro is not mentioned. OneyedK could you please let me know what does cpuz report for the non pro sticks in the SPD section and what is the memory revision?
