Server memory upgrade for workstations

The OWC 64GB DDR4 3200 ECC Registered RDIMM is built for servers and workstations that require registered error-correcting memory. It matches the specifications of Kingston KSM32RD4/64HCR and KSM32RD4/64MFR modules. This 288-pin DIMM operates at 1.2V with a CAS latency of CL22. It is not compatible with standard desktop computers.

Check platform and memory configuration

Verify that your motherboard supports DDR4 3200 registered ECC RDIMMs before ordering. This module uses a 2Rx4 rank organisation and cannot be mixed with unbuffered memory. All installed DIMMs should share the same capacity, speed and manufacturer for optimal performance. Confirm the system accepts 64GB per slot and 288-pin registered modules.

Build quality and daily handling

The module follows JEDEC-standard specifications and is RoHS compliant. No heat spreader is fitted, so airflow across the PCB is required in dense server chassis. Gold-edge contacts on the 288-pin interface ensure reliable seating in registered DIMM slots. OWC tests every module in-house to meet or exceed OEM specifications for long-term service.

Questions sur cet article

Does the 288-pin DDR4 ECC RDIMM arrive as a single 64 GB module or do I need to order multiple sticks to reach that capacity?

The listing describes one 64 GB DDR4 3200 CL22 1.2 V registered 2Rx4 module, so the full capacity is delivered in a single stick.

When should I choose this 64 GB 2Rx4 registered ECC module instead of a lower-capacity or unbuffered alternative?

Select this module when your server or workstation requires registered ECC DDR4 3200 memory and you want the maximum 64 GB per slot in a 2Rx4 configuration.

What does the PC4-25600 rating mean for actual throughput once the module is installed in a compatible system?

PC4-25600 indicates a peak transfer rate of 25 600 MB/s at the rated DDR4 3200 speed with CL22 latency.
