32GB DDR4 2666 ECC RDIMM Server Module

This 32GB DDR4 2666MHz ECC registered DIMM is built for servers and workstations that require error-correcting memory. It runs at 1.20V with CL19 latency and a 2Rx4 organisation on a 288-pin form factor. The module targets administrators upgrading HP platforms listed in the compatibility data.

Replaces Slower or Smaller DDR4 Registered DIMMs

The module replaces lower-capacity or lower-speed registered ECC memory in compatible HP systems such as part numbers 815100-S21, 832798-B21 and 881900-B21. The upgrade is worth it when the platform supports 2666MHz operation and the workload benefits from the additional 32GB capacity per slot.

Straightforward DIMM Installation

Installation follows standard 288-pin DIMM seating in the correct memory channel order for the specific server model. What usually goes wrong is mixing registered and unbuffered modules or populating slots in an unsupported sequence, which prevents the system from posting.

Questions about this item

Does the 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the module uses the 288-pin DDR4 DIMM form factor and is a registered ECC RDIMM designed for server and workstation slots.

What is the correct way to seat the 32GB 2Rx4 module so the ECC register initialises?

Align the notch with the slot key, press firmly until both retention clips click, and ensure the 1.20V power rail is stable before boot.

When should the 32GB DDR4 2666MHz ECC RDIMM be replaced?

Replace the module if memory diagnostics report uncorrectable ECC errors, the system fails POST with this DIMM installed, or capacity no longer meets workload demands.
