Targeted DDR2 upgrade for HP dc7900

This 4 GB DDR2-800 module is built for HP Compaq Business Desktop dc7900 SFF CMT and MT systems. It uses a 240-pin unbuffered non-ECC DIMM running at 1.8 V with CL6 timing. The single stick installs directly into one of the four available slots.

Suited for dc7900 owners adding memory

Buyers who need to increase memory on a compatible dc7900 desktop will find this module matches the required specification. It is not for systems that require ECC or registered DIMMs. It is not for platforms that use a different DDR generation or a different pin count.

4 GB DDR2-800 CL6 240-pin specification

The decisive specification is the 4 GB DDR2-800 CL6 unbuffered non-ECC 240-pin DIMM at 1.8 V. Only systems that accept this exact combination will operate correctly with this module.

Preguntas sobre este artículo

Will the 240-pin DDR2 DIMM fit the four slots in my HP dc7900 SFF, CMT or MT?

Yes, the module matches the 240-pin DDR2 layout used by all three dc7900 chassis variants and the board provides four DIMM sockets.

What is the correct way to seat this 240-pin DDR2 stick so it locks in place?

Align the notch with the slot key, press straight down until both side clips snap shut, then verify the stick does not rock.

When should I replace this 4 GB DDR2 module?

Replace it if the system fails to POST with only this stick installed or if memory diagnostics report uncorrectable errors.
