overclocking corsair pc4000

[mpegripper]

hey guys,

i have the setup below and i can get my cpu to 2.5GHz, but i can't seem to get my ram to 250MHz x2=500, which is what the ram is rated at!!!!!!

i've loosend the timings a bit and brought the voltage from stock(2.75) to 2.9 without success. i seem to top out around 230x2=460.

I am testing with prime95 and when i run the memory intensive test i get errors at about 1 minute.

Any ideas?

TIA

Drop your multiplier on the cpu, then max out your memory with a clock speed you know your cpu can handle....also use the bios default memory timings to see if it hits 250mhz
