i have a asus gamers republic nforce 790i sli ultra motherboard, intel quad core 3.0ghz processor,and a 1.7gb nvidia 275gtx....the problem is the memory(CAS Latency).i dont get it,what is good
LOWER CAS latency OR HIGHER CAS
1. GSKILL 4gb DDR3 2000MHz and 1600MHz CAS 9-9-9-24-2N
2. OCZ 4gb DDR3 1800MHz CAS 8-8-8-27
3. CORSAIR DOMINATOR 4gb 2000MHz CAS 9-9-9-24
which would be a better buy?
HELP

here's a tip for you:
The total latency in seconds can be calculated as follows:
(1/frequency)X(sum of all latencies)
lower the latency better is the ram
eg.for ocz ddr3 1800mhz latency=(1/1800x10^6)(8+8+8+27)=28.33 ns
for crossair dominator latency=25.5 ns

so go for crossair dominator,its the best
