Hey guy This weekend my dad got new motherboard and i took one of his 1gb DDR2 ram sticks out and put it in my computer which also is for DDR2 i have it in there now but when i put it in i noticed the ram i put in out of dads computer was bigger then the one that its next to....... I didnt need to force this new ram stick or anything and its working my computer is now saying i have 3gb of ram but just wondering if it can be damaging to my computer becuase it looks totally different to the 2gb one that came with my computer.
