    whip out your manual for your machine, then once youve determined which 2 slots are for each ram channel you can put the ultra sticks in 1 channel and the other hp sticks in the other channel

    i would advise not to mix the two simply for compatibilitys sake

    Most manufacturers now have a hardware manual for their MoBos in pdf format on their web sites. That manual should answer your questions.

    It is in the BIOS you select the memory access mode. Also, I don't think it matters which sticks of memory go in which slots but I'm not certain. Memory is memory so long as they are of the matching type.

    Black & Blue, My Memory is Bruised.......

    Industry practice is that each memory channel has 2 different color sockets. Intel uses blue for 0, the one that must be populated first, then black is the other socket (#1) for the SAME channel. If I had 2 sticks of RAM I would install one in each blue channel FIRST. Then I would expand the memory by installing the second 2 DIMMs in the black sockets.
    One caveat: read the damned instructions anyway, and look forward to only having the system recognize about 3 GIGs of the installed RAM (unless the board BIOS is 64 bit enabled). This has been covered many times on this site, so do yourself a favor and poke around until you find these relevant threads.
    Here is Tedsters guide to adding RAM, always a good read:
