the Gigabyte board is the only one with four ram slots. i have one. handy because you can run >2 DIMMs in dual channel mode!!! i have the 7NNXP, the one with llllooooooooadsa features (more than any other nForce 2 board) but the SPP version. love the board so far, although ive never liked that patronising colour coding all the manufs. seem to be insisting on at the moment. i do have one little problem with the PATA raid, but i think its something ive done and not a common problem. haven't tried it with 4 slots populated, but running 2x Corsair 256Mb PC2700 CAS2 in 1 DIMM in each channel
