Hi, I had to replace the memory in my acer 5520 laptop its now working much faster but theirs still and issue , I took out the 4gb ram and replaced with new 4gb ram but the system is only saying theirs 2.75 gb ram installed so I ram memory diagnostic which said no issue found so I took both sticks out and put in indervidually and it ready one stick at 1.75 gb so I tried the ofher and that also reads as 1.75gb when on their own, so I next tried them in my other laptop that reads then as full 4gb so I then put them back in the other lsptop but when they in together they read as only 2.75gb can anyone advise what this could be thanks

It sounds like you are using a 32-bit version of Windows. You need the 64-bit version to reference more than 3Gb of memory. I assume the other missing quarter gig is used for graphics, so not available to Windows.

Note: you must have a 64-bit processor to use the 64-bit versions of Windows.
