16 GB DDR4-2400 ECC registered RDIMM with CL15 latency and 1.2 V operation for HP-compatible servers
This 16GB DDR4-2400 ECC Registered RDIMM is built for servers and workstations that require error-correcting memory. It suits administrators expanding capacity in compatible HP platforms or similar 288-pin DDR4 systems. The module uses major-brand DRAM chips and meets OEM specifications for reliable operation in multi-DIMM configurations.
Verify that your motherboard accepts 288-pin DDR4 SDRAM with ECC and registered buffering. The platform must run at 1.2V and support PC4-19200 speed with CL15 timing. Confirm the maximum rank population per channel to ensure the 2Rx8 organisation is allowed. Systems limited to unbuffered UDIMMs or non-ECC memory cannot use this module.
The module installs directly into 288-pin DDR4 DIMM slots wired for registered ECC memory. It draws 1.2V and operates at DDR4-2400 without additional configuration in most compatible BIOS settings. Adding capacity reduces swapping and paging, freeing CPU cycles for virtual machines and demanding applications. The RDIMM design helps signal integrity when multiple modules populate each channel.

The listing is for one 16 GB DDR4-2400 RDIMM; additional modules must be purchased separately to reach your desired capacity.
The 2Rx8 registered ECC design matches HP part P00423-B21 and is built for servers that require registered memory; verify your platform supports 2Rx8 before ordering.
The module runs at DDR4-2400 with CL15 latency at 1.2 V, providing PC4-19200 bandwidth when the server's memory controller operates at that speed.
