if ur motherboard supports it yes, but if u only have a 32bit os u will only be able to read 3.3gbs so unless u have a 64bit os its a waste, get one 2gb stick and a 1 gb stick n u should be set if u have a normal 32bit os

frequently a 1GB DDR 4 hundred SODIMM sells for around USD30 (~ AUD30) in US. So i assume AUD39 sounds very very nearly top, interior the worst case $seventy 5~ $a hundred. yet I have not got any theory why they have listed some for as severe as $4 hundred, perchance they're bulk expenses (20 products and so on..) or some previous listings / blunders picked up via that seek engine. Don’t hassle approximately those, get the extra low priced ones. they're each and every of an analogous. Corsair, G.means , Kingston, Hynix, PNY are some conventional RAM manufacturers, get a sort of (instead of the different no-call/ unbranded stuff).

it depends. is it a 62 operating system or a 32? 32 bit only allows up to 3gb and 62 allows to 8gb. u can check in control panel, system maintenance, system and u will see it.
