AMDs prefer lower CAS. But go with the 1600. That will be able to do 1333 CAS 7.

^That. Buy the Crucial stuff. It works great. Why go CL9 when you get good CL8 stuff? And they look cool.

Of course if you are looking for 4G sticks it costs a bit more to find CL8.

My ram is 1600 cas 9-9-9-24.

And I run it at 1333 7-7-7-20, and overclocked the fsb so it stays the same ratio and runs at like 1450mhz cas 7 biggrin.gif

The ratio of the lower ram speeds in your motherboard is much better than the higher ram speeds in your motherboard.


1600mhz will run at 1333 7-7-7-20
