HP DC5800/DC7800 DDR2 Upgrade

This 2 GB DDR2 800 module is built for HP Business DC5800, DC5800 MT, DC5800 SFF and DC7800 SFF desktops. It delivers a direct memory increase for those specific chassis without requiring configuration changes.

240-Pin Unbuffered DIMM Fit

The stick uses the standard 240-pin DDR2 DIMM form factor and runs at 1.8 V with CL6 6-6-6 timing. It slots into an empty DIMM socket on the supported HP boards and operates as non-ECC unbuffered memory.

2 GB Single-Module Capacity

One module provides 2 GB of PC2-6400 bandwidth using sixteen low-density chips in a 2Rx8 layout. Systems needing more than 2 GB total or requiring ECC registered memory will need a different specification.

Questions about this item

Will the 2 GB DDR2 800 CL6 module throttle under sustained load without a heat spreader?

The stick has no heat spreader and runs at 1.8 V; in a DC5800 or DC7800 chassis it relies on case airflow, so prolonged heavy use may hit thermal limits faster than spreader-equipped DIMMs.

How much noise, heat or extra power does this 1.8 V DDR2 800 DIMM add when the workstation runs all day?

It draws standard DDR2 power at 1.8 V with no fan or LED, adding negligible noise and only modest heat that the existing system cooling handles.

What must the HP DC5800 or DC7800 already have for this 240-pin DDR2 800 CL6 stick to work?

An empty 240-pin DDR2 DIMM slot and BIOS support for PC2-6400 unbuffered non-ECC memory; the module is a single 2 GB 2Rx8 stick.
