[SOLVED] That is better 2 dual rank dimm's or 4 single rank?

[HomidWay]

I want to add more RAM, what is better for FX8320 to have 4 single rank dimm, or 2 dual rank.

NB frequency is OC to 1600, memory clock is 1800 in both cases, 16 gb is that's important.
Currently i have stutters in most games and as far as I know it's RAM issue (fx works best at 1800 dual rank or 2400 single). So in case of ram performance that should I prefer?

Just to make it clear, i'm talking about ranks not channels.

2 dual...check the motherboard website and make sure what you buy is on the tested list.

What games are you running? The eight core FX CPUs rule, and were great gaming CPUs for a long time. Nowadays, they're going to have trouble with the most recent AAA stuff. 16GB of DDR3-1600 is not a limiting factor*, regardless of layout. Unless you have a non-gaming use case for more memory, I'd recommend leaving the memory configuration the way it is.

*unless you're running a very fast CPU for high frame rates in CPU-and-memory-heavy games.

Dual Rank, dual channel. #dimms depends on board topology (serial/parallel). For Vishera you want IMC at least 2xRAM speed if I recall. So for DDR-1600 (800MHz) you need 1600MHz NB, but you can probably push it to 3GHz or more and it will reduce latency even more. If I recall I could do DDR3-2000CL8 and 3000MHz NB on my FX-4100.
