PC2700 will work fine, but you should get PC3200 RAM, PC2700 is only rated
to 166/333Mhz whereas PC3200 is rated at 200/400Mhz - which is what you want
for an XP3200+. You will not get PC2700 RAM to run stably at 200Mhz unless
you have top end Brands like Corsair XMS, OCZ, Mushkin etc.... So you may
well be OK.
I would question your reasons for upgrading, seeing that you already have a
Barton XP2500+ you can very easily overclock this chip to an XP3200+ by
simply raising the FSB and keeping the RAM in sync. To do this though, you
would need to have PC3200 ram installed. Before you bite the bullet why
don't you overclock your existing chip, if you do want some help/guidance do
this then just post back and I will help you out.
Sorry if this clouds the water for you..
