how do I check if my 1gb is ddr2 ah?
and should I upgrade to 4gb? Because youyayu mentioned something
bout 'cannot read'..
Using xp professional sp2 btw
for windows professional sp2, 32bit systems, 2gb would be enough.
Yes, youyayu is right, when you have 4gb, you will only see 3gb
listed up in your bios ect. No, no one's cheated you but it's a
restriciton of 32bit systems. If it's 64bit, then yea. you can see
your 4gb
use this to test: http://www.softpedia.com/get/System/System-Info/CPU-Z.shtml (cpu
z) though most laptop rams are ddr2.
it doesnt matter about the mhz part. if yours can only support
up to let's say give a number like 200mhz type of ram, you can
still use a 667mhz ram, your laptop will just mark it
down to the max speed that it can support. but you
must make sure that the 667mhz ram is of the same ddr
