Hi.
AMD Athlon XP 2500+ Barton Core @166FSB
MSI K7N2G-L motherboard (3 ports for DDR up to 3GB total and dual channel)
Kingmax 2x256MB DDR 400 (PC3200) RAM Dual channel @200 (400)

Having problems installing new 2x512MB DDR400 (PC3200) on this motherboard when running it in dual channel @ 200. Runs fine when in 1:1 with fsb of cpu @166, but any higher and it does not boot.

Why is it that I can run 2x256MB DDR 400 at 200 (400), but when I take that out and insert 2x512MB DDR 400 in the same slots it only runs at 166 (333)? Does this make any difference? Any help would be much appreciated. (if need any more info let me know).
