64GB DDR5 ECC RDIMM for Supermicro Servers

This single 64GB registered DDR5 module operates at 6400MHz with CL52 latency and 1.1V power draw. It targets IT teams upgrading Supermicro X14SBW-F platforms that require ECC error correction and registered signal buffering for stability.

4Rx4 organisation and major OEM chips

The 4Rx4 rank layout uses Samsung, Micron or Hynix components to meet dense server workloads. ECC and registered operation together protect data integrity and reduce electrical load on the memory controller in multi-DIMM configurations.

Tool-free DIMM slot insertion

Alignment notches on the 288-pin edge connector prevent backwards insertion. Installers must verify the motherboard Qualified Vendor List and populate slots in the order the manual specifies; mismatched ranks or missing BIOS updates are the usual causes of POST failures.

Questions about this item

Will the registered 4Rx4 DDR5 module require any firmware updates or component swaps during its service life?

The module is a standard 288-pin DDR5 RDIMM with on-die ECC; no user-serviceable parts or firmware updates are needed after installation.

What electrical or thermal limit appears first when the 64 GB stick runs at 6400 MT/s continuously?

The JEDEC 1.10 V operating voltage and CL52 latency define the power envelope; sustained loads stay within the rated DDR5 specification.

How much additional heat does the bare 288-pin module contribute when the server runs around the clock?

Without a heat spreader the module relies on chassis airflow; at 1.1 V typical power draw is low enough for standard server cooling.
