With 64 bit Win7, you will still only see 3.xGB of memory because the O/S uses the rest for its internal 'housekeeping' including the O/S itself. With 8GB of memory, you will have use of all the 8GB of RAM minus the necessary housekeeping amount mentioned earlier.

Swpp, are you using the integrated video on the motherboard? The integrated video will use some of that 4 GB for its memory. Depending on your motherboard's BIOS settings, you may be able to control how much memory it uses.

Also, depending on which specific chipset your motherboard uses, you may be limited to only about 3.5 GB of RAM total, even if you are using 64-bit Windows.
