16GB DDR4 ECC RDIMM for HP Servers

This 16GB registered DIMM uses DDR4 2666MHz PC4-21300 technology with ECC error correction. It targets administrators upgrading compatible HP ProLiant or workstation platforms that require registered memory. The single-module design suits slot-limited configurations where maximum capacity per slot matters. Systems needing unbuffered UDIMMs or non-ECC memory cannot use this module.

Capacity and registered headroom

The 16GB capacity handles virtualisation hosts, database buffers and multi-user workloads with room for simultaneous VMs. Registered buffering reduces electrical load on the memory controller, allowing larger total system memory than unbuffered alternatives. Workloads exceeding 16GB per module or requiring higher frequencies than 2666MHz will need additional modules or faster-rated memory.

Major-brand chips and lifetime backing

Modules are built with major-brand chipsets and tested to CL19 latency at 1.20V standard voltage. The 288-pin DDR4 DIMM form factor fits registered DIMM slots in qualified HP systems matching part numbers 838089-B21 and P06184-001. US-based technical support assists with compatibility verification before installation.

Questions sur cet article

Will this 16GB DDR4 2666MHz ECC RDIMM run reliably alongside my existing registered DDR4 modules?

Yes — this module is a registered DDR4 2666MHz ECC RDIMM at 1.20V with CL19 timing and 2Rx8 organisation, so it will operate at the speed of the slowest module installed.

How can I confirm the 288-pin module is detected and running with ECC active after installation?

Enter the system BIOS or UEFI and verify the memory shows 16GB at 2666MHz with ECC enabled; the POST memory count should also report the full capacity without errors.

What comes in the box and do I need any extra parts to install this 1x16GB RDIMM?

The package contains one 16GB DDR4 2666MHz 288-pin ECC RDIMM; no additional components are required for a standard server DIMM slot.
