Dual Channel DDR vs. Overclocking Dual Channel DDR

What is the difference between the two. I do plan on overclocking my new system so which one would be better to get.

btw I plan on getting DDR 3200 of which every one would be best for me.

 

A pair of rams is better than 2 sticks of rams, one of these kind with one others, they supports at the same CAS and You can OC and get faster than normal .
I remmber if it is not wrong mobo support dual ram it will be faster from 15-20% than unsupported mobo.
at amoment I OCed my pair of Gskill from PC4400@ PC5400.

 

So would you say that I need to get overclocking dual channel or just the normal dual channel? Here is the motherboard.

Thanks in advance.

 

Dual channel must be OCed you will ge more FSB for ram and CPU .
