Q4GB memory is not recognized by Windows correctly.
AThis is due to a limitation in 32bit operating systems that exists in notebook computers of other manufacturers. Although the address space of the 32bit operating system is 2³²= 4294967296 = 4,096MB = 4GB, all of it cannot be allocated
to memory, as some of it needs to be used for other purposes by the operating system. Because approximately 1GB of address space needs to be allocated to other system resources such as the BIOS, PCI Device, and VGA for a PC to operate normally. Therefore, even if 4GB of physical memory is installed, the address space allocated to memory is limited to approximately 3GB.
Although users can upgrade their memory to 3 or 4GB, only 3GB is recognized even when 4GB of memory is installed, and a memory upgrade to 4GB is not recommended.
