HPE 16GB DDR4 2133MHz ECC LRDIMM

This HPE 774173-001 module provides 16GB of DDR4 memory for compatible servers and workstations. It operates at 2133MHz with a CAS latency of 15 and includes ECC for data integrity. The LRDIMM form factor suits systems requiring higher density per slot. Buyers who need non-ECC memory or a different form factor such as UDIMM or RDIMM should look elsewhere.

Installing the 288-pin module

Align the notch on the 288-pin edge connector with the slot key and press firmly until the retention clips engage. The module runs at 1.20V, so the platform must support DDR4 voltage levels. A common issue is mixing LRDIMMs with other DIMM types in the same channel, which prevents the system from posting. Verify the server memory population rules before adding this stick.

16GB single-rank capacity decision

This single module delivers 16GB in a 1 x 16GB configuration using LRDIMM technology. The capacity and rank structure determine how many modules the memory controller can address per channel. If the target system requires a different density per DIMM or a specific rank count not met by this part, it will not be compatible.

Questions about this item

How can I verify the 16GB DDR4 2133MHz ECC LRDIMM is recognised correctly after installation?

Check the system BIOS or management console to confirm the module appears as a single 16GB DIMM running at 2133MHz with ECC enabled and CL15 latency reported.

What is included with the 774173-001 module and what must be sourced separately?

The box contains one 288-pin LRDIMM; any additional DIMMs, compatible HPE server chassis or memory risers required for your configuration are not included.

Which capacity and speed version should I select for a slot that requires 1.20V DDR4 ECC LRDIMM?

Choose the 16GB 2133MHz CL15 variant (part 774173-001) to match the 1.20V DDR4 ECC LRDIMM specification for that slot.
