hi all, i have aquired a asus P5N72-T premium board and am trying to run 1066 ram. ive got the corsair pc8500C5DF ram wich is in corsairs QVL for the board, the bios is not picking up the 1066 rating, an will only allow the ram to run at 800 mhz. ive tryed to set the timings manually which still posts but doesnt get it at 1066, when i got to set the ram fsb rating manually at linked the thing wont post. when i run the cpuid in windows it picks up the epp for the ram but is running at 800 mhz
i have 2x2 gig ram, os vista 64 bit, bios v 6.02
im stumped any help would be appreciated, thanks

the epp is set to 800mhz by default so its always going to be set at 800mhz..

try unlinking and setting it to 1066.

also, i know the striker uses the final value in the bios settings. and since the p5n72 is the same board, i assume it would be the same. something to keep in mind.

hi, i tryed it unlinked also with no luck, i can manually set the timings and voltage to 1066 and the settings work and will boot to windows at the 800mhz tho, but still doesnt detect the 1066 and set to, in the bios with out hanging after exiting the bios

am setting the timings to 5-5-5-15-2T at 2.1v will boot no probs, but if i set to 1066 no luck.
have also tryed linked with fsb/memory ratio, if i set the sli ready in bios it will auto detect 1066, but will hang evry time i touch the sli ready settings and exit the bios

JIPPED
asus replyed to me stating i read the qvl in the mobo book, that states 4 ram sticks none of which are 2gig stick and there is only one 2x1gig sticks that are compatible to run in 1066,the other 3 are one gig sticks, how the bloody hell they can state this mobo is 1200/1066 compatible is a lie.
silly me went to the corsair qvl which states support for the ram i have for this mobo

take my advice stay away from this mobo peoples

Staying away from silly over-priced, don't-make-a-shit-of-difference enthusiast RAM is better advice. :)

Because, really, you'd have been better off with 2x2gb of whatever old DDR2-800 you could lay your hands on for < $100.

Remember that for next time. You could try running that RAM at 800Mhz with 4-4-4-12 instead of 5-5-5-15 timings. That might work for you, and is better than nothing, but still won't make any difference you're going to notice outside of comparing benchmark scores.

ur probly right if money is a factor, but i got the p5n72-t premium because of it competative pricing, and i got the 2x2 gig sticks of 1066 for $150 bucks, i eventually got it going no thanks to asus, i overclocked the fsb to 1500(1333 standard), unlinked the ram manualy set to 1066 set ram voltage to 2.1v and left everything else on auto, the timings are a bit looser but is running stabily now @ 1066
