ASUS P5W DH - Problems + Fixes Thread

[sesdave]

I must be really unlucky because my XMS2 6400c4 memory has microns as the sticker on my modules says it's rev 1.1 and I can't get it to boot with FSB at 400 and manual memory timings of 4-4-4-12. Even at stock FSB speed, it doesn't work with manual memory timings of 4-4-4-12, maybe because the board has problems with the 2:3 ratio (is that correct ?)

And yes I'm setting the memory voltage to be 2.1v

Try 2.2v -These sticks should do 1000MHz plus no problem with about 2.3v-2.4v Check this review out - http://www.xbitlabs.com/articles/mem...dr2-800_2.html
What BIOS are you running and whats the rest of your BIOS settings and system setup.
Check the forum for previous threads on 2:3 and 4:5 on the P5W. This one was an Analysis of P5W DH memory 4:5 and 2:3 dividers with an earlier BIOS version by eva2000

Another thought - have you removed NB/SB heatsinks and replaced paste with AS5. It all helps the overclock stability and keeps board cool. Your problem may not be the memory but the overall setting/volts you are using in the BIOS - please post them.
