Server memory upgrade

This OWC module delivers 64GB of DDR4 ECC registered memory at 3200MHz for Supermicro platforms. It matches the specifications of Supermicro part numbers MEM-DR464L-CL02-ER32, MEM-DR464L-CL03-ER32 and MEM-DR464L-HL02-ER32. The 288-pin RDIMM operates at 1.2V with CL22 latency and a 2Rx4 rank configuration. It is designed for workstation and server environments that require registered ECC memory.

Compatibility check

Verify that your motherboard supports DDR4 ECC registered RDIMMs before ordering. This memory will not function in standard desktop computers or systems requiring unbuffered modules. Registered and unbuffered memory types cannot be mixed in the same system. Confirm the platform accepts 2Rx4 rank modules and 1.2V operation for stable performance.

Upgrade impact

Adding this module increases total system memory capacity for virtualisation, database or compute workloads. ECC error correction protects data integrity in critical applications. JEDEC compliance and RoHS adherence ensure a warranty-safe upgrade path. The module extends the service life of existing infrastructure or reduces cost when configuring new server deployments.

Questions about this item

Does the 64GB DDR4 3200 module ship with any cables, brackets or software, or must those be purchased separately?

The module is a single 288‑pin RDIMM; no cables, brackets or software are included and none are required for installation.

How do I decide between the Supermicro part numbers MEM-DR464L-CL02-ER32, CL03-ER32 and HL02-ER32 that this OWC module replaces?

All three Supermicro part numbers share the same 64GB 2Rx4 DDR4 3200 CL22 1.2V specification, so this single OWC module covers every listed variant.

What does the PC4-25600 rating mean for actual throughput once the DIMM is installed in a server?

PC4-25600 indicates a peak transfer rate of 25,600 MB/s per module at the rated DDR4 3200 speed.
