at the site which im getting my pc, those 2 different ddr's are labled as dual channel, are they really?

They are if you stick two sticks in a dual channel board.

If the RAM works, then it will most likely work in a dual channel motherboard.

Memory DIMMS aren't dual channel, just the platform they plug into.

What the site claims is that they have tested the memory on various platforms to make sure the pairs work. There are a number of gotchas that might cause instability or reduced performance in dual channel mode that may or may not be the fault of the motherboard, memory, processor, or all of the above.

For example, the DIMM specs show it to be double-sided, which cause reduced memory clock speeds if you try to populate all the memory slots on most models of Athlon 64.

Whether you should worry depends on exactly what platform you are looking at, as well as how many sticks you want to use.
