Memory ■ A 32-bit operating system can not address more than 4 GB of memory. If your configuration has two 2 GB memory modules, only approximately 3 GB will be reported. This is not a wrong display, but a technical limitation of chipset, CPU and BIOS. ■ The reason is that various system resources (like Flash, APIC, PCI devices, GPU) require their own address space within the available 4 GB limit. In case of 4 GB of physical memory the address space used by the system resources overlaps the physical memory. ■ The operating system has not the possibility to use the memory in the overlapped address range. This reduces the addressable memory space available to the operating system. Because Windows only displays the available memory instead of the computer's physical memory, you will only see approximately 3 GB. Slots Video RAM 1,024 MB, 2,048 MB or 4,096 MB memory modules can be installed in the two memory slots. Maximum system memory size and speed are depending on the model you purchased. The amount of Video RAM available is dependent on the computer's system memory. Start  Control Panel  Appearance and Personalization  Personalization  Display Settings. The amount of Video RAM can be verified by clicking the Advanced Settings... button in the Display Settings window. The amount of Total Available Graphics memory will vary be between 1 and 2 MB depending upon system configuration. User's Manual 1-3
