ASUS P5B-E Sound problem

[udontnome]

Am ready to do a new build w/C2D overclocking hard. I've been reading in personal reviews and comments that there are quite a few problems with the onboard sound on this board and am not sure from some of the comments if disabling the onboard in BIOS and using a SB Audigy fixes the problem or if you still have to disable the 'execute disable bit' which results in XP reporting only 3gig in a 4 gig setup. Anyone?

There's the rub, some of the reviews of Newegg's buyers imply that disabling the onboard sound doesn't fix the problem. They don't say it specificaly though. The memory reporting will be very important to me as I plan on installing Vista as soon as it's built.
