P4P800 Deluxe users question..dual mem

Hey all. All of you guys who have the P4P800DL I wanted to know if I can match both slots of ram with matched ram? Or is only the blue slot for dual channel? Can I put in another matched pair of ram into the black ram slots and dual channel as well from that? I would like to get 4 sticks of 256 and try it out. Any thoughts?

Both slots are for dual-channel. You will get better performance, more stability, and probably improved ocing potential if you get 2x512 as opposed to 4x256.

Actually, 4x512mb will give you the best performance (4x double sided ram), then 4x 256mb (4x single sided ram), then 2x 512mb (2x double sided), then 2x 256mb (2x single sided).

You would have to put them in in pairs, same or like modules in black slots, ditto for the blues. That will give you dual channel memory. You can populate 3 slots but you lose dual channel.

But according to the P4P800 manual the mobo doesn't like certain memory in ALL 4 SLOTS. e.g. Corsair XMS. The bottomline is check the manual about your memory.

He's correct. My reference was to 1gb total memory. Using 4x? size sticks you will probably have trouble getting your timings as tight as you can w/ 2x? size.

Yeah, you'll lose some overclockablity (made that word up myself ) with 4 sticks over 2 but the bandwidth is better. There were a few articles with comparisons a few months ago about it and they showed Sandra charts proving their claims.
