64GB DDR4-2666 ECC LRDIMM for servers

This 64GB DDR4-2666 ECC LRDIMM targets administrators who need to maximise memory capacity in compatible HP server platforms. The module delivers 64GB at 2666MHz with a 4Rx4 organisation and registered buffering. It operates at 1.20V and carries a CL15 latency rating.

HP 832800-B21 equivalent with major-brand chips

The module matches HP part number 832800-B21 and uses Samsung, SK Hynix or Micron components. It is guaranteed compatible with systems requiring this specification and is designed to maintain existing service contracts. No additional software or accessories are bundled with the memory stick.

288-pin installation with rank and voltage checks

Installation follows standard 288-pin DDR4 DIMM seating; the key notch prevents misalignment. The most common issues arise when mixing 4Rx4 LRDIMMs with different rank configurations or when the platform does not support load-reduced modules at this capacity. Verify the server qualification list before fitting.

Questions about this item

Will the 4Rx4 LRDIMM organisation require any special BIOS setting or future firmware update to stay compatible?

The module follows the standard DDR4 2666 CL15 1.20 V JEDEC profile, so no extra BIOS configuration is needed and no firmware update is expected for the memory itself.

What thermal or power ceiling appears first when the DIMM runs at full 2666 MT/s continuously?

At 1.20 V the 64 GB LRDIMM stays within the normal DDR4 power envelope; the platform memory-controller thermal limit will be reached before the module itself overheats.

How loud and hot does the 64 GB LRDIMM get during all-day operation?

The stick has no moving parts and draws 1.20 V, so it adds negligible noise and only modest heat that the server’s existing airflow handles without extra cooling.
