In what cases would you recommend dual channel ram?

As above ty. (i'm currently on single channel btw)

(how to find out if programs can utilize dual channel ram?)

dual channel is a configuration supported by motherboards. Don;t confuse dual channel with DDR (double data rate). now most rams are DDR already. so how you install your rams in the motherboards determines if you shall get it run on dual or single channel.

in real world applications, won;t see musch difference lah. google it for answers

DC = 128bit membus, more latency.

SC = 64bit membus, less latency.

You choose.

Personally I'd never use single channel RAM if a motherboard works with DC or TC (LGA1366).

It's like driving a car on three sports rims and one spacesaver.

Thanks both for the reply. BTW i found out the answer already.

this link clearly shows the difference, so i have decided to stay with single channel ram.

DDR double data rate means reading of the data two time, once at the rise of the cycle and again at the fall. instead of SDram that reads the data once in a cycle.

to run dual channel (i.e to have two modules running parallel in DDR, you need a motherboard configured for it, and your placement patterns of the modules on the mobo.

Call4Ljw your link seems like only for 1 core type, sandy bridge - wonders how the oler or otehr core type perform with SD, DDR,DDDR2 and DDR3?

i know my link is only for sandy bridge, but since i'm using sandy bridge processor that is of course my main concern.
