One thing you should be aware of if you want to use the SoundStorm audio on an nForce board is that it can only be used with digital speakers. If you use the analog speaker ports you only get audio from whatever cheap onboard audio system the motherboard manufacturer included which are worse than the SB Live! card. This is something that I never see mentioned when talking about SoundStorm audio, even on nVidia's site.
I've been using OCZ RAM with my Abit NF7-S nForce2 motherboard and haven't any troubles with it. It doesn't appear to be on the official nForce compatiblity list, but it was tested by Abit.
