Just bought some Kingston 1600mhz cas11 ram, didn't check the cas latency when I purchased, would 1333mhz cas9 have been noticeably better? If so I can exchange them. If not ill just install these. Exchanging wouldn't be much trouble.

Thanks!

They'll be almost exactly the same in perf as the lattencies and data rates are about the same

no... they are the same speed (1600/11 = 1333/9)...

first i would change the bios ram settings to 1333 99927 to see if the 1600 ram works at that rate... it should. in general you can "slow down" memory but not speed it up... (overclocking issues aside)...

kingston ram tends to be rock-solid ... so it does not oc'd much... but you might try the 1600 Ram at 1333 88824 or 77721 nd see if it is stable...

if not return it and get 1600 88824... much more expensive (65-85) dollars for 8GB
 
VERY little difference outside of runing a benchmark.
Generally Speed trumps cas lattencies.
Just a side comment, You have a SB CPU. Running ram above 1333 voids the Intel CPU warranty - Only a problem if CPU dies. Many do run ram (including Myself) at 1600 for SB CPUs. Default for the Newer IV is DDR3-1600.
