HP dx2200 manual Installing Additional Memory, DDR2-SDRAM DIMMs

Hardware Upgrades

Installing Additional Memory

The computer comes with double data rate 2 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 two industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. The sockets are labeled DIMM1 and DIMM2. To achieve the maximum memory support, you can populate the system board with up to 2GB (2 x 1GB) of memory.

DDR2-SDRAM DIMMs

For proper system operation, the DDR2-SDRAM DIMMs must be:

■industry-standard 240-pin

■unbuffered PC2-5300 667 MHz-compliant

■1.9 volt DDR2-SDRAM DIMMs

The DDR2-SDRAM DIMMs must also:

■support CAS latency 4 (CL = 4) for PC2-5300 667 MHz

■contain the mandatory JEDEC SPD information

In addition, the computer supports:

■256Mbit, 512Mbit, and 1Gbit non-ECC memory technologies

■single-sided and double-sided DIMMS

■DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported

✎The system will not start if you install unsupported DIMMs.
