getting the most out of my memory

[GTI125]

I have a gig of OCZ PC4000 and am interested in getting the most out of this memory, I know how to over clock the cpu i have gotten my P4 3.2 up to a stable 3.5, just need some help with the memory

raise the vdimm voltage as high as it will go on your motherboard and then lower each of the timings as low as you can get them with the computer remaining stable.

OCZ PC4000 doesnt like low timings, if your motherboard supports memory ratios greater than 1:1, id get your memory clocks as close to 250mhz as possible, with the stock timings.

it is possible to get 2.5-3-3-6 out of ocz 4000. 2.5-4-3-6 is almost guaranteed up to about 270mhz fsb.

This is from the OCZ web page "speeds of up to 500MHZ at CL 2.5-4-4-8. " Now i moved my ratio from 1:1 to 3:2 and CPU-Z is saying that my latency is 2.5-3-3-5 at 148.8MHZ, is this good?

how do i get close to the 500 MHZ that OCZ says that i can acheive?

no that is not good. You want to leave your memory at 1:1 and then manually set your latencies as low as you can get them. The ras to cas is the hardest to get low. I would shoot for 2.5-3-3-6 with your memory 1:1. but your ras to cas may not like going below 4 1:1, but then again it just may.

edit.

your not going to get to the 250/500mhz that the memory is rated at with a 3.2ghz processor. If you have one of the newer MO stepping cpus you might get it up to 240/490mhz though.
