High-density server module

This SK hynix 64GB DDR4 2133 module is a 288-pin LRDIMM with ECC and a 4Rx4 rank structure. It operates at 1.20V with a CAS latency of CL15 and carries Supermicro certification for validated compatibility. The load-reduced design allows higher per-slot capacity in supported platforms.

Suited for memory-bound workloads

Administrators expanding Supermicro-qualified servers or Cisco UCS B-Series B260 M4 v4 systems can use this module to increase total memory without adding slots. It is not for consumer desktops or workstations that require unbuffered non-ECC UDIMMs. Buyers needing registered RDIMM instead of load-reduced LRDIMM should verify their platform requirements before ordering.

64GB 4Rx4 LRDIMM at DDR4 2133

The single specification that determines fit is the 4Rx4 load-reduced organisation combined with DDR4 2133 speed and ECC. Only platforms qualified for this rank structure and voltage will recognise the full 64GB capacity per module.

Questions about this item

Does the 288-pin DDR4 2133 LRDIMM fit the B260 M4 v4 memory slots?

The module uses the standard 288-pin DDR4 form factor at 2133 MT/s and is Supermicro certified for the B260 M4 v4, so it installs directly into the server's DIMM slots without adapters.

What is the correct way to seat this 4Rx4 64GB ECC module during installation?

Align the notch on the 288-pin edge connector with the slot key, press straight down until both retention clips click, and verify the system recognises the full 64GB at DDR4 2133 CL15 in BIOS.

Will the 1.20V LRDIMM require any firmware or thermal maintenance over its service life?

The module runs at 1.20V with no heat spreader and no moving parts; ensure the server's airflow remains unobstructed and apply any B260 M4 v4 BIOS updates from Supermicro for continued compatibility.
