Server Memory for Workstations and Servers

This OWC 64GB DDR4 module is built for workstations and servers that require ECC registered memory. It operates at 3200MHz with a CL22 latency and 1.2V voltage. The 2Rx4 rank configuration and 288-pin RDIMM form factor target enterprise infrastructure upgrades.

Registered ECC Compatibility Requirement

The single specification that decides fit is the registered ECC design. This memory will not work in standard desktop computers and cannot be mixed with unbuffered modules. Buyers must verify their platform specifically supports DDR4 registered ECC RDIMMs before purchase.

JEDEC Compliance and OEM Match

The module meets JEDEC standard specifications and matches Supermicro part numbers MEM-DR464L-HL03-ER32, MEM-DR464L-SL01-ER32 and MEM-DR464L-SL02-ER32. This compliance ensures a warranty-safe upgrade for compatible OEM systems without requiring additional configuration.

Questions about this item

What does the 64GB capacity mean for a server workload?

A single module adds 64GB of ECC Registered DDR4 memory, letting the server address larger datasets and run more virtual machines simultaneously.

How does the DDR4 3200 PC4-25600 interface limit real-world throughput?

The module runs at 3200 MT/s with a peak bandwidth of PC4-25600; actual throughput is capped by the memory controller and the number of populated channels.

What physical slot and clearance does the 288-pin RDIMM need?

It fits a standard 288-pin DDR4 RDIMM socket and has no heat spreader, so it clears most CPU coolers and dense server chassis.
