DDR3 selection for MSI 790FX-GD70

So I'm set on this motherboard for my build...

Heres my problem... Everything I read and watch says the board is amazing and they keep mentioning RAM overclocking to 2133mhz, but never mention using say 2000mhz, or actually 2133mhz ram, its all over clocking 1333mhz or maybe 1600mhz Im not quite sure. Is there a reason for this? I have noticed that the 2000mhz RAM has high Cas Latency like 9, while 1333mhz and 1600mhz go as low as 6. Im totally lost here

If you are overclocking, 1600MHz CAS8/CAS7 is better.

CAS is CAS Latency, lower is better. The higher speed can offset the higher latencies.

Officially, AMD and Intel only support 1333MHz RAM, but motherboard makers offer higher dividers, so all you would have to do is go into the BIOS and change the RAM multiplier so it runs at the rated speed.

You will also need to change the timings and voltage to what the sticks are rated for.

Now is it possible to get Ram thats 2000mhz, and change the Cas Latency in the Bios? Say get the 9 and change it to 8? Im guessing this is what overclocking memory is? But in return of changing 2000mhz cas latency 9 to latency 8 its going to drop the mhz of the memory anyway.. yes?

Yes, you can change the timings yourself but stability is not guaranteed... you might get bluescreens, errors, crashes, or the system might not even POST, in which case you'll need to clear the CMOS.
