32GB DDR4-2666 ECC Registered RDIMM

This Brute Networks module delivers 32GB of DDR4 server memory at 2666 MT/s. It operates at 1.20V with ECC error correction and registered buffering. The 288-pin DIMM uses a 2Rx4 organisation and major-brand chips. It is built as a direct equivalent to HPE part number 840758-691.

Suited for HPE servers needing registered ECC DIMMs

This module fits systems that require DDR4-2666 registered ECC memory in a 32GB density. It is not for platforms that accept only unbuffered non-ECC UDIMMs. It is also not for boards limited to lower DDR4 speeds or different pin counts. Buyers needing other capacities or voltages should choose a different part.

2666 MT/s DDR4 speed rating

The single specification that decides fit is the DDR4-2666 (PC4-21300) speed grade. The memory controller must support this exact data rate for the module to run at its rated frequency. If the platform only qualifies slower or faster DDR4 grades, this DIMM will not operate as specified.

Questions about this item

What speed does the PC4-21300 DDR4-2666 interface actually run at in a server?

The module operates at 2666 MT/s, delivering the full PC4-21300 bandwidth when the platform supports that data rate.

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

Yes, the 288-pin RDIMM form factor matches standard DDR4 server slots used in HPE systems that accept registered memory.

How do I install this 2Rx4 ECC registered module correctly?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify the configuration in BIOS.
