Hardware Upgrades Installing Additional Memory The computer comes with double data rate synchronous dynamic random access memory (DDR1-SDRAM) dual inline memory modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to two industry-standard DIMMs. These memory module slots are populated with at least one preinstalled memory module. To achieve the maximum memory support, you can populate the system board with up to 2 GB of memory. DDR1-SDRAM DIMMs For proper system operation, if the computer supports unregistered non-ECC DDR1-SDRAM DIMMs, the DIMMs must be: ■ industry-standard 184-pin ■ 2.5 volt DDR1-SDRAM DIMMs ■ unbuffered PC2100 266 MHz-, PC2700 333 MHz-, or PC3200 400 MHz-compliant ✎ Though a PC3200 400 MHz DIMM can be installed, a memory frequency of 400MHz is not supported; therefore, the PC3200 DIMM functions at 266MHz or 333MHz, depending on the frequency of the processor front side bus. The DDR1-SDRAM DIMMs must also: ■ support CAS latency 2 or 2.5 (CL = 2 or CL = 2.5) ■ contain the mandatory JEDEC SPD information In addition, the computer supports: ■ 64 Mbit, 128 Mbit, 256 Mbit, and 512 Mbit non-ECC memory technology ■ single-sided or double-sided DIMMS (does not support double-sided X16 DDR1 DIMMS) 2-4 www.hp.com Hardware Reference Guide
