I have 2gig of Mushkin ddr2 800 5-5-5-15 running in my system now; and I have 1gig of corsair ddr2 675 cas4 sitting in a package collecting dust. I was wondering if mixing these two on my computer would create stability issues in either XP, Vista or Ubuntu. My X2 3800 is OC'd to 2.4ghz, by the way, and I have this all running on an Asus M2N-E.
