Server memory for enterprise workloads

This OWC module provides 64GB of DDR4 ECC load-reduced memory rated at 2400MHz with CL17 latency. It is built for servers, workstations and NAS systems that require registered DIMMs. The single stick delivers high density without occupying multiple slots. It will not work in standard desktop computers.

JEDEC compliance and backward speed

The module meets JEDEC PC4-19200 specifications and is ROHS compliant. It operates at 1.2V and can also run at 2133MHz when installed in systems limited to that speed. No heat spreader is fitted, so airflow in the chassis must be sufficient for bare DRAM packages.

4Rx4 rank configuration decides fit

The 4Rx4 organisation determines whether the memory controller can address this module. Systems limited to dual-rank or single-rank DIMMs will not support it. Verify the platform’s qualified vendor list for 4Rx4 LRDIMM compatibility before purchase.

Soalan tentang produk ini

Will the 4Rx4 ECC LRDIMM need any firmware updates or component swaps over its service life?

The module is a sealed JEDEC-compliant DDR4 LRDIMM with no user-serviceable parts; no firmware updates or component swaps are required during normal operation.

What limits sustained throughput first on this 2400 MHz CL17 64 GB stick?

The DDR4-2400 bus and CL17 latency set the maximum sustained bandwidth; the memory controller cannot push data faster than the rated PC4-19200 speed.

How much heat and power does a single 1.2 V 288-pin LRDIMM produce when running 24/7?

At 1.2 V the module draws only the power needed for DDR4-2400 operation and runs without a heat spreader, so thermal output stays low in typical server airflow.
