4 stick dual channel help

[Sunborder]

I am putting together a P4 system on the I685PE chipset(dfi lanparty).

Now I have two Kingston 512 valueram sticks that I want to put in dual channel. My question is this: if I succeed in getting them to run in dual channel(bought together, so should be ok), can I later buy 2 more and still have it run in dual channel mode?

If so, do all four have to be identical, or can I have kingston valueram x2 and kingston something-else x2?

I don't want to shell out for two 1gb modules when Doom3 is released.

Yes, you can run 4 sticks in dual channel.

The two sticks of memory in the second channel don't have to be the same brand as in the first channel, though it is better to avoid memory conflicts and to have all the RAM at the same speed and timings and such.
