Hardware Upgrades Installing Additional Memory The computer comes with double data rate synchronous dynamic random access memory (DDR2-SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 8GB* of memory configured in a high-performing dual channel mode. DDR2-SDRAM DIMMs For proper system operation, if the computer supports DDR2 SDRAM DIMMs, the DIMMs must be: Industry-standard 240-pin Unbuffered 800 MHz-compliant DDR2 800 MHz DIMM 256Mbit, 512Mbit, and 1Gbit non-ECC memory technologies single-sided and double-sided DIMMS The system will not start if you install unsupported DIMMs. *8GB Memory is supported only with Windows Vista 64 bit or Freedos operating systems !!
