What this module does and who needs it

This 16 GB DDR4 ECC RDIMM is a registered server memory upgrade built to replace HP part L58117-001. It targets administrators who need to add capacity to compatible HP server or workstation platforms that require registered ECC modules. Buyers who need unbuffered UDIMM memory or non-ECC modules for consumer desktop boards cannot use this part.

The specification that decides fit

The module runs at DDR4 2933 MHz (PC4-23400) with CL21 latency at 1.20 V and uses a 1Rx4 rank organisation on a 288-pin DIMM. Your system must support registered ECC DDR4 at this speed and voltage; if the platform requires a different rank configuration, voltage or pin count the module will not function.

Installation notes and common issues

Installation is a standard DIMM insertion into the server memory slots, but the 288-pin registered form factor will not fit consumer 262-pin SODIMM sockets. The most frequent problem is purchasing without confirming the exact HP part number and supported memory list, which leads to returns when the system refuses to post.

Questions about this item

How does the 2933MHz speed translate once the module is installed in a server?

The module runs at DDR4 2933MHz (PC4-23400) with CL21 latency, delivering that data rate when the platform's memory controller is configured for 2933 MT/s.

What does the ECC RDIMM registered interface mean for system compatibility?

The module is an ECC Registered DIMM (1Rx4) that presents a registered clock-driver load to the memory controller and requires a platform that supports registered ECC DDR4 DIMMs.

Will the 288-pin DIMM fit my server's memory slots?

The module uses the standard DDR4 288-pin DIMM form factor (noted as 262-pin in some documentation), so it fits servers designed for DDR4 RDIMM slots.
