HP-compatible 16 GB DDR4-2133 registered DIMM

This module is a 16 GB DDR4-2133 registered RDIMM built to match HP part number 753221-B21. It runs at 1.20 V with CL15 latency and uses a 2Rx4 organisation on a 288-pin PCB. The stick carries ECC and is assembled with major-brand DRAM chips.

Suits HP servers that require PC4-17000 registered

IT teams maintaining HP infrastructure can use this module to expand or replace memory without voiding the factory warranty. Systems that need unbuffered UDIMMs, a different speed grade, or non-ECC memory cannot use this part.

Registered ECC with 2Rx4 organisation decides fit

The registered buffer and 2Rx4 rank layout are required by the target HP platforms; a UDIMM or a different rank configuration will not post. Verify the server’s qualified vendor list for this exact specification before ordering.

Questions about this item

How do I install the 288-pin DDR4 RDIMM and which step is often missed?

Power down the server, open the chassis, align the module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all 16 GB are recognised at 2133 MT/s.

What maintenance or replacement will the 16 GB registered module need later?

No scheduled maintenance is required; the module carries a lifetime warranty, so a replacement would only be needed if a memory error appears during sustained operation.

What limit appears first on this CL15 1.20 V kit under sustained load?

The DDR4-2133 speed ceiling and CL15 latency set the bandwidth and response-time boundaries before thermal or voltage limits become a factor.
