64GB DDR4 2133 LRDIMM for servers

This SK hynix 64GB DDR4 2133 CL15 1.2V 4Rx4 LRDIMM is a load-reduced ECC module built for high-density server memory configurations. It uses a 288-pin form factor and operates at PC4 17000 speed with a CAS latency of 15.

Suited for qualified Supermicro platforms only

This module is validated and Supermicro certified, so it fits administrators upgrading or repairing qualified Supermicro systems that specifically support DDR4 2133 LRDIMMs. It is not for desktop motherboards, consumer laptops, or any platform that requires unbuffered UDIMMs or standard registered RDIMMs instead of load-reduced memory.

The deciding spec is 4Rx4 LRDIMM

The quad-rank 4Rx4 load-reduced organisation is the single specification that determines whether this part will work in a given server. Systems qualified only for single-rank or dual-rank RDIMMs cannot use this module, and mixing LRDIMMs with other DIMM types in the same channel is not supported.

Questions about this item

What comes in the box with the SK hynix 64GB DDR4 2133 LRDIMM and do I need to buy anything else?

The module is a single 64GB 288-Pin DDR4 LRDIMM with ECC and a CL15 latency rating. No extra components are included or required for installation.

How do I decide between the listed versions or capacities for this SK hynix DDR4 2133 server memory?

This SKU is a single 64GB 4Rx4 LRDIMM running at 2133 MT/s with 1.2V operation. Choose it when your platform needs one high-density registered ECC module of this exact specification.

What does the 2133 MT/s speed mean once the SK hynix LRDIMM is installed in a real server?

The module transfers data at 2133 MT/s (PC4-17000 bandwidth) with CL15 timing at 1.2V, delivering the rated throughput when the memory controller is configured for DDR4-2133 operation.
