Hi peeps, merry xmas to you all ;p I just installed 2 strips of DDR2, the exact make my Asus MB requires as the old ram that was in it was different speeds. Originally it had 1.5gig so i repleced the 2 strips for 2x1gig strips of matcjing everything. So switched PC on and now windows tells me i onlyhave 1 gig installed ! Cpuz tells me both are there and tells me the exact info that is required but windows only tells me i have 1 gig now when it said i had 1.5gig with miass matched ram ?? Puter seems smoother so my question is, :- Is W7 32bit using 2gig or is it not ? Why cant thing just work lol lol lol also on the ram it states it is PC2-4200 DDR2 Memory RAM DDR2-533 533MHz but if you check the cpuz file it states different . Dont know what to do now. is the ram faulty ? miss labeld ? or what ? Thanks for any ideas. Here is the cpuz file.
