I have what I believe to be an older 550vw and I wanted to know if it
is possible to upgrade its currtent single 733 to dual 1gig xeons. I
can't seem to find any clear info on this online and the manual is only

showing that and upgrade to dual 933's. I remeber reading somewhere
that some 550 mobo's cannot support dual 1gig xeons. Can anyone tell me

if this is true. thanks.
