Dual vs single channel ram

[dayto11]

Hi, I was wondering if it would be better to have 1 stick of vengeance running at 1600 (single channel) or 2 sticks at 1066 runing dual channel which is better thanks dayto

In dual channel mode your memory bandwidth doubles and you will get better performance. While one module reads the other one writes.

You will not see a performance increase in gaming with 1600 vs 1066 even if you get the 1600 the motherboard will just clock it down to 1066 or 1333 or to whatever memory speeds your motherboard supports. I'll stick to the 2 1066 modules in dual channel or get 2 sticks of those 1600's but you will probably have to manually change the memory timings in the bios (for the 1600's), the only benefit you will get with the 1600's is if you are overclocking.

i tweaked the the 1600s but its still a bit slower than what i would like i am getting another vengence so i am fine thanks

Wow! This is a false statement. Dual-channel works like a raid setup: a few bytes on first ram module, a few bytes on the other. The system reads or writes from both at the same time but it doesn't reads on one while it writes on the other...

now i am confused please explain the dual / single channel memory

This is not complicated: dual-channel works twice as fast as single-channel since it divides read/write operations evenly between memory sticks.
