OT, that Twinmoss3200 is bollox BB, it's very cheap but the stuff I have has VERY tight timings on it, it won't do cas2 @ 200mhz (it 'SPD's to cas3 but was rated 2.5 when I brought it)...
If I was you I'd look at the Twinmoss 3700, still cheap by far!, but rated 2.5 like any other 3700 rated mem I've seen so far...
Hmm, that Asus is lost to the rev2 NF7S as well!
