Like I said I have the same motherboard and the same manual. It didn't
even allow for the PII 450 I originally had in it. Using Crucial
Memory's finder showed the 256 MB memory modules and they worked fine.
They weren't available when the manual was printed. I had the board
running 768 MB of memory under XP with no problems.
The finder on Crucial Memory also shows ECC memory in the same sizes,
for a considerable cost increase.
