HP s dx5150 manual Installing Additional Memory, DDR-SDRAM DIMMs

Hardware Upgrades

Installing Additional Memory

The computer comes with double data rate synchronous dynamic random access memory (DDR-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 (1-Gbit Technology) of memory configured in a high-performing dual channel mode.

✎The memory available may be limited by the operating system.

DDR-SDRAM DIMMs

For proper system operation, if the computer supports DDR-SDRAM

DIMMs, the DIMMs must be:

■industry-standard 184-pin

■unbuffered PC3200 400 MHz-compliant

■2.5 volt DDR-SDRAM DIMMs.

The DDR-SDRAM DIMMs must also:

■support CAS latency 3 (CL = 3)

■contain the mandatory JEDEC SPD information In addition, the computer supports:

■128Mbit, 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.
