64GB DDR4-2133 LRDIMM for servers

This 64GB module uses 288-pin DDR4 technology at 2133 MT/s with CL15 timing. It operates at 1.2V and carries ECC plus load-reduced buffering. The 4Rx4 organisation suits high-density slots in compatible HP platforms.

Installation notes for LRDIMM modules

Align the notch with the 288-pin slot and press firmly until the latches click. Load-reduced DIMMs require motherboard support for LRDIMM technology; standard RDIMM-only boards will not recognise them. Populate slots per the server manual to keep 4Rx4 ranks within the controller limit.

Suits HP upgrades needing 64GB density

This module matches HP part 726724-S21 and is built with major-brand chips. It fits administrators expanding memory in qualified HP servers. Builders needing non-ECC UDIMMs, lower capacities, or faster speeds should look at other product lines.

Questions about this item

How can I confirm the 64GB DDR4-2133 ECC LRDIMM is running at PC4-17000 speed and CL15 latency after installation?

Check the BIOS memory information screen or run a tool such as CPU-Z; it should report 2133 MT/s, 1.20 V, CL15 and ECC active for each 288-pin module.

What is included with the 726724-S21-BN module and what must I source separately?

The box contains the single 64GB 4Rx4 Load Reduced DIMM; no extra cables, brackets or software are supplied — compatible HP server slots are required.

Which capacity and rank version should I choose for a server that needs 64GB per slot with 4Rx4 organisation?

Select this 64GB 4Rx4 DDR4-2133 ECC LRDIMM; it matches HP part 726724-S21 and fills one 288-pin slot with the full 64GB capacity.
