Memory; Dimms; Ddr2-Sdram Dimms - HP dx2810 - Microtower PC Service & Reference Manual

Memory

The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) dual inline memory modules (DIMMs).
CAUTION:

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.
DDR and DDR2 memory modules are not interchangeable.
