HP dc7700 tower 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 PC2-4300 533 MHz-compliant, PC2-5300 667 MHz-compliant, or PC2-6400 800 MHz- compliant

●1.8 volt DDR2-SDRAM DIMMs

The DDR2-SDRAM DIMMs must also:

●support CAS latency 4 (DDR2/533 MHz and DDR2/667 MHz) and CAS latency 5 (DDR2/667 MHz and DDR2/800 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

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