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 both in dual channel.

 

 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? 

 

EDIT:   

I'm talking about RANK of memory not channels.

4 ram slots can still work in dual channel.

Just to add a bit to what @Samfisher there said: the number of DIMM-slots doesn't have anything to do with whether you're running dual-channel or not. The number of channels is about how many channels the memory-controller has and how many of them it can utilize in parallel, not how many DIMM-slots you have. Indeed, you can still be running dual-channel even with 4 sticks of RAM.

Are you sure whatever you have now doesn't work cuz of RAM? How high is your RAM usage? Dual channel should be better 4 sure...Your CPU supports it, and I am sure motherboard should too...

I know, i'm not talking about CHANNELS, i'm talking about RANKS.

I never owned that CPU family but on more modern systems, in general a given number of rank per channel seems to be have identically. It's not the rank of the individual module that matters, but the total rank per channel.

 

e.g. 1 dual rank module per channel performs the same as 2 single rank modules per channel, assuming all other parameters are the same.

 

In theory there could be a difference because the rank and 2DPC timings are separate and thus may differ, but in practice it seems to be the same.

Hope it's so, then i'll just add 2 dimms to current setup, and see how it will perform

if the cpu supports 4 channel...then go with 4 sticks...if it supports 2 channel...then do what ever is cheapest...make sense?
