Dual Channel Memory Question

[Brookie]

Gonna bump up my memory to 4 gigs from 2 (now that I've gotton around to seeing how cheap its gotton).

My Motherboard has two dual channel slots (two different colored sets of memory slots), a blue and a white slot. Currently my two sticks are (presumedly) dual channeled in the blue slot.

If I want to continue running dual channel, does it matter if the memory is different then the ones in the blue slot? I'm looking at buying a cas5 latency kit to add to my cas4 latency current setup. Will this disable dual channel or will it continue working since they are in different sets?

All the memory will run at the slowest speed, dual channel or no. Actually, you might want to confirm that it is doing so in your BIOS in case it's not picking up the stray (it helps sometimes to have the slow stick in the first slot). You can usually underclock RAM with no trouble, but overclocking doesn't always work.
