I have a computer which has an ASUS P5B motherboard and an Intel Pentium D
Processor and runs Windows XP.
It has 4GB of DDR2 RAM (4 x 1GB). All RAM chips are of the same type and
manufucturer. In BIOS setup, when i go to "system information" it shows that
the pc has 3GB of RAM instead of 4 and In Windows XP, in "System properties"
window (right click on my computer -> properties) it shows 2,93 GB of RAM.
But in "System Information" (Start menu -> All programs -> Accessories ->
System tools -> System Information) It says
Total Physical Memory: 4,096.00 MB
Available Physical Memory: 2,44 GB
Why the computer only uses 3GB of RAM ?
Is there a maximum for the amount of RAM memory which can be
used in Windows XP ?
