i bought 2gb corsair ram 800mhz from
elive.nz i forgot that 32bit systems have 4gb limit
i have amd64 3.2ghz twin dual core processors does that mean i can switch to a 64bit operating system because we have windows xp pro 64bit cd at home as well as 64bit enterprise and ultimate so would i just be able to install over my 32bit system?
because if i want more ram in the future it would be good because 64bit os have 128gb limit which is massive!
which one should i install xp or vista?
