DDR3-1866@CL9 or DDR3-1600@CL8?

I am thinking about getting this motherboard:

With this CPU:

My question is about RAM. Would I be better off with 8GB of DDR3-1866 with a CL of 9

OR 8GB of DDR3-1600 with a CL of 8:


I am upgrading from an Athlon X2 5600 w/ 6GB of DDR2-800. I want a very snappy computer that can recode videos much faster. Occasional light gaming.

I have a 96GB SSD boot drive, and have recently upgraded to windows 7 pro -64, in case any of that info helps. Mainly I want to startup quick, load programs quick, encode video quick.

Which set of ram is better at stock speeds and which would be better if I choose to OC? Thanks for your time! Any other comments on my upgrade path are also welcome.

    More specifically 1600 8-8-8-24 vs 1866 9-10-9-28 ; IMO 1600 8-8-8-24 + less issues. AMD is 'funky' in that kits that 'should' work often don't so you need to be very cautions. I know ASUS updated the QVL lists recently so IMO git it a look. And yes I'll spare you the LGA 1155 opinion.

    Alternative 1600 7-8-7-24-2N @ 1.60v F3-12800CL7D-8GBXH

    Your AMD 6-core can run DDR3 2000. My experience is the Higher Frequency BUT loose CAS isn't faster then High Frequency AND tight CAS. Therefore, F3-12800CL8D-8GBXM would be my choice for INTEL.

    Neither kit is designed for AMD 9XX chipsets; so no guarantees.

    AMD Kits:
    1600 9-9-9-24-2N F3-12800CL9D-8GBRL
    1600 9-9-9-24-2N CMP8GX3M2A1600C9

    1866 9-10-9-27-2N CMZ8GX3M2A1866C9
