optimal RAM settings?

Recommended Posts

Hello. My PC, using the Gigabyte GA-P35-DS3L mobo, has 8GB of Corsair RAM (two twin2x4096 packs) running @ 2.1v, 4-4-4-12, 800MHz speed.


Running MemSet 3.5, my other RAM settings are:

tRFC is at 42

Performance Level 9

Write to Precharge Delayed 13

tWTR 10

tRRD 3

tRD_WR 8

tRTP 5

tREF 3117


I was told these settings ought to be optimized, and SiSoft Sandra shows a high latency as well.


How can I best modify these settings to reduce latency?


Thanks much!!

I can do 4-4-3-9 @ 800MHz fine (1:1 ratio), but keeping the CPU @ 400MHz and upping the FSB to 1000 (at 5-5-5-15, same voltage), the system crashes within 5 minutes.


Could this be because I am using a 400MHz bus; and 1:1 being better for stable overclocking of the CPU anyway?
