Check below for some more posts on a Mobile XP2500+. I have two of them but have only tested them on NF2 motherboards. I do have a GA-7VAX I could test it on, and actually had planned on doing so soon. Your board is the same but with Raid. I can't make promises as to how soon I will test it. I am swamped right now. But maybe i'll grab that system and try it out for a breather some time this weekend.
