Targeted Upgrade for HP 6000 Pro

This 4GB kit contains two 2GB DDR3-1066 modules built specifically for the HP Business Desktop 6000 Pro in both Microtower and SFF chassis. It is designed for users restoring or maintaining these workstations within the original memory specification. Buyers needing capacities beyond 16GB or a different memory generation will not be served by this product.

Standard Voltage Unbuffered Operation

The modules run at the standard 1.5V DDR3 voltage with CL7 timings and no heat spreader attached. As unbuffered non-ECC DIMMs they draw typical low power for desktop memory and produce no additional fan noise beyond the system's own cooling curve. No overclocking headroom or special thermal requirements are implied by the specifications.

Dual-Channel Pair for Four-Slot Boards

The two sticks must be installed as a matched pair to activate dual-channel mode on the platform's four DIMM sockets. Each module uses a 240-pin edge connector and a 2Rx8 organisation. The system bus locks at 1066MHz even if faster DDR3-1333 modules are present, and a 64-bit operating system is required to address the full 4GB capacity.

Questions about this item

How do I install the two 240-pin DDR3 modules into the HP Business Desktop 6000 Pro and what step is often missed?

Insert each module into matching-colour slots so the pair runs in dual-channel mode; the step often missed is populating the second channel instead of filling a single channel first.

Will the 2Rx8 unbuffered DDR3 sticks need any firmware updates or battery replacements later?

No firmware or battery is involved; the modules are passive DRAM and only require reseating if contact oxidation appears after several years.

At what speed ceiling does the memory bus lock when all four slots are populated under sustained load?

The system documentation states the memory bus runs at 1066 MHz regardless of module rating, so that is the sustained ceiling.
