Recommendations on RAM with A8-5500 and Asus A85XM-A

Going to be running Windows 7 Home 64-bit.  Mobo lists DDR3-1600 as top option, but CPU spec shows DDR3-1866.  Asus shows the CPU is compatible with this mobo.  Looking at systems on the market, they are using DDR3-1600.  Thoughts?

DDR3 1600 should be fine, the difference in speed is negligible, unless you are running on board graphics in which case the speed difference may become more of an issue.

if you're looking for speed... then find a 1600 module with the lowest CAS latency.

IMO CAS latency makes a bigger difference than a couple mhz in clockrate

Also, DDR3-12800 modules are going to be easier to find and thus get a better deal on.

7 CAS is going to be the shortest latency on that memory spec

Wasn't looking for recommendations on performance, but the fact of function vs fail.  More research looks like the CPU can communicate at the higher speeds, but not required.  I will soon find out.  Thanks to everyone for their input.
