Server memory module

This 8 GB DDR4 registered DIMM runs at 2933 MHz with CL21 latency and 1.20 V operation. It uses a 1Rx8 layout and major-brand chips to deliver ECC-protected capacity for compatible HP server and workstation platforms. The 288-pin form factor fits standard DDR4 RDIMM slots.

Replacement part numbers

The module is specified as a direct equivalent for HP part numbers P00918-H21, P00918-K21, P00918-S21 and P06186-001. Buyers can match these codes against their system documentation to confirm fitment without cross-referencing other vendor lists.

Registered ECC requirement

This stick only works in systems that accept registered ECC DDR4 RDIMMs; it will not function in desktop boards or laptops that require unbuffered non-ECC memory. Verify the platform supports registered DIMMs before ordering.

Questions about this item

Will the registered ECC module need any firmware updates or battery replacements over its service life?

No firmware or battery maintenance is required; the module is a passive DDR4 component validated at CL21 and 1.20 V.

What electrical limit appears first when the DIMM runs continuously at 2933 MHz?

The 1.20 V operating voltage and CL21 timing define the thermal and signal-integrity ceiling under sustained load.

How much power does the 1Rx8 registered DIMM draw and how warm does it get during all-day operation?

At the standard 1.20 V the 8 GB module typically draws only a few watts, producing minimal heat in a server chassis.
