HP DX7500 manual Installing Additional Memory, DDR2-SDRAM DIMMs

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 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 8-GB of memory configured in a high- performing dual channel mode.

DDR2-SDRAM DIMMs

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

●industry-standard 240-pin

●unbuffered PC2-6400 800 MHz-compliant

●1.8 volt DDR2-SDRAM DIMMs

The DDR2-SDRAM DIMMs must also:

●support CAS latency 5 DDR2 800 Mhz (5-5-5 timing) and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)

●contain the mandatory JEDEC SPD information

In addition, the computer supports:

●512Mbit, 1Gbit, and 2Gbit 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

NOTE: The system will not operate properly if you install unsupported DIMMs.
