Hi,

I'm using 4 X 512MB DDR2 667 rams, should I try with 2 X 512MB to OC it or just stick with all 4 pcs. ? I've been getting 800MHz with stock voltage @ 4-4-4-12, when I hit 1000MHz, I can get a stable performance from 5-5-5-15 @ 1.9V, but can't seem to get stable performance for 4-4-4-12 eventhough I'm using 2.1V, any way to improve it ? should i try 2.2V ? Coz i'm not sure if its safe or not.

thanks in advance for all the advices.
