hi,

i just bought some of this ram -

corsair xms2 (2x2gb) pc8500. it has an advertised speed of 1066mhz and timings of 5-6-6-18.

problem is when i configure it to those settings in bios my pc wont even boot up. when i reduced the speed to 1030mhz it boots up but i get blue screens of death.
ive now reduced the speed to 900mhz and the problems seem to have disappeared.

to the matter of my pc not booting up, is this because the ram voltage isnt high enough? and why do i get crashes at the speed i mentioned above?

ive already had the ram replaced so it defo cant be faulty ram. if i keep the ram at a stable speed of 900mhz am i losin out on much performance as opposed to 1066mhz? im just a bit annoyed that it wont boot up with the advertised speed.
 
i cant see in bios what my ram voltage is as i have it set to auto. my cpu is at its default 1.31250v.

could that be whats causing the instability at higher speed? should i even bother tryin to get it runnin at 1066mhz or am i just as well leaving it at 900mhz?
 
ive installed cpu0z and i cant see any dram voltage value. am i gonna see much of a performance improvement in gaming with the ram runnin at 1066mhz as opposed to 900mhz?
