32 bit operating systems will recognize about 3.5 GB of RAM. To utilize more RAM would require installing a 64 bit operating system. This is true in all recent versions of Windows.
As far as mixing RAM, you can use different brands...and even different speeds...so long as you use the correct type of RAM for your motherboard. When mixing speeds of RAM, you will be limited to running at the speed of the slowest module. That is, if you install one stick of 800 MHz RAM, and one stick of 1066 MHz RAM, the machine will run with the 800 MHz speed.
