AMD - Dual Channel DDR3 Or Single Channel DDR3. What should I do?

Hello there! I'm in quite the pickle and thought I would come to this great resource to get some advice.

I have an AMD processor (AMD Phenom II X2 555... unlocked to 4 processors) and I'm thinking about getting a new AMD motherboard that supports DDR3 1600 (which then would of course support DDR3 1333).

I can either buy DDR3 1600 running at CAS 8 - Single Channel (it comes in 3, 2GB sticks).

OR

I can buy DDR3 1333 running at CAS 9 - Dual Channel (comes in 2, 4GB sticks).


As far as I know there aren't any AMD boards that support triple channel, but of course I could be wrong.

What would you suggest I do? The pickle that I'm in is that I can go with 6GB ram which is faster than the 8GB ram but since it will run in single channel, I'm not sure if it will be faster.

Memory basics 101: the ram speed is determined by the board chipset. Get a matched pair for amd boards; it doesn't have to be dual channel; get whatever speed you can afford. I use both 1333 and 1600; most 1333 will run at 1600 with manual ram settings in the bios. All newer Amd boards take the memory in pairs, not threes.

I get you (sort of). What I'm saying is that the ram that I'm getting is going to dictate whether I run in single channel or dual channel (and from Memory basics 101 as far as I could remember, dual channel has a higher bandwidth than single channel :)  ). I can run both of these different modules in the motherboard I want to get. But I was wondering if running in single channel is worth it because the RAM that I want to get is faster (cas 8 timing) than the other ram that I could also buy that would run in dual channel (the cas 9). If I'm understanding you correctly, are stating that I could OC the 1333 ram to 1600 but I'm sure that with the CAS 9 timing it wouldn't be worth it? idk, I'm more of one to just get a nice PC to work and not have to overclock.

I hope that is easy to understand. :bounce: 

EDIT: I ended up getting the 8GBs. I just can't wait for good advice. :lol:
