CMS 2 GB DDR2-800 DIMM for HP Business

This 2 GB DDR2-800 module is built for HP Business DC7900 CMT, MT, SFF and DX2310 systems. It uses a 240-pin unbuffered non-ECC design running at 1.8 V with CL6 timing. The single stick lets you add memory to a supported desktop without replacing existing modules.

Suits owners of the listed HP models needing a 2

Builders working on any other platform cannot use this DDR2 DIMM because the pin layout, voltage and timing are specific to the named HP systems. Buyers who need ECC, registered memory or capacities above 2 GB per module should look elsewhere.

DDR2-800 (PC2-6400) speed rating

The module operates at 800 MHz with 6-6-6 latency at 1.8 V. This speed and voltage combination is the deciding factor for compatibility with the target HP desktops. If your system requires a different DDR2 speed or voltage, this stick will not work.

Questions about this item

Should I pick the 2 GB stick or look for a 4 GB version?

This module is a single 2 GB stick; the listed systems accept up to 4 GB per slot, so adding a second identical stick will give you 4 GB total.

What does PC2 6400 mean for my DC7900 or DX2310?

PC2 6400 is the industry label for DDR2 800 MHz memory, so the stick will run at the native bus speed of those systems.

Will the 240-pin DDR2 DIMM fit the motherboard slots in a DC7900 CMT, MT, SFF or DX2310?

Yes, all four models use standard 240-pin DDR2 DIMM sockets, and this unbuffered non-ECC stick matches the required pin-out and voltage.
