dual channel ram ???

It should run in dual channel. Memory companies sell matched DC pairs that are tested in DC mode, but you should be fine.
 
It would be recommended that both sticks be of the same vendor, specs and size. Dual Channel kits are just 2 sticks that have been tested together at their specific timings and speed.

get same cas and size
 
Someone please explain dual channel operation to me. Is it through dual channel operation that the 400 MHz DDR400 can run at 800 MHz?

If so, do you sacrifice memory size for speed in order to achieve 800 MHz dual channel operation?

In other words, if you have two matched 512 MB sticks and you want to configure them for dual channel operation, is all data transfer then being split in two (half routed to one stick, half to the other), effectively giving you only 512 MB at twice the speed as two single channel sticks, or are there two data channels on each stick that are activated by dual channel system configuration?

Pardon my ignorance on all this, but I really appreciate the help you guys give!

It's like having 2 data channels. Basically you can read twice as much data at once without sacreficing any quantity of memory. Like having 2 straws to drink twice as fast and not losing any liquid.

I have an a no longer produced stick of 512mb 2.5cas pc2700 samsung ram, i cant buy the same model anymore but if i just get different brand of ram but with 2.5cas 512mb and pc2700 will it be able to run in dc well?
 
I have used completely different brands and even different sizes and never had a problem with dual channel. I think alot of it is just a company trying to get a few more bucks by slapping the dual channel sticker on it. But I have seen some people have problems running certain memory in dual channel. But I do think it is pretty rare to have any problems crop up.

The motherboard usually determines dual channel operation based on what slots you put the memory in.

gigabyte 8IG1000 pro

According to the manual for that board, you need to put one dimm in slot 1 and the other in slot 3 to acheieve dual-channel performance (or slots 2 and 4). Just don't have them right next to each other. It should automatically detect that it is dual-channel. When the computer boots up, watch the screen to see if it says so anywhere.
