OWC 64GB DDR4 3200MHz PC4-25600 CL22 4RX4 ECC LRDIMM 1.2V 288-pin Server RAM

SKU CH-39A6-G925S

64 GB DDR4 3200 MHz ECC load-reduced DIMM for servers, workstations and NAS systems with CL22 latency and 1.2 V operation

  • Capacity64GB
  • Type288-Pin DDR4 ECC LRDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22

Capacity 64GB

  • 64GB single module doubles server capacity instantly
  • ECC load-reduced design protects data integrity under load
  • DDR4 3200MHz CL22 speed accelerates throughput for virtualization

Single 64 GB DDR4 LRDIMM for servers

This 288-pin module delivers 64 GB of ECC load-reduced memory at DDR4 3200 with CL22 timing and 1.2 V operation. It targets administrators upgrading workstations, servers or NAS systems that require registered ECC DIMMs.

Limited to platforms that accept LRDIMMs

The module follows the JEDEC DDR4 3200 standard and is backward compatible with 2133, 2400, 2666 and 2933 MHz bus speeds. It will not function in consumer desktops or laptops that only support unbuffered non-ECC memory, and it cannot be mixed with unbuffered DIMMs in the same system.

Replaces lower-capacity or slower registered DIMMs

Installing this 4Rx4 stick increases total memory capacity in a single slot, which is useful when all DIMM sockets are populated or when moving from 2133, 2400, 2666 or 2933 MHz modules to the 3200 MHz speed grade. The jump is worthwhile when the platform supports load-reduced ECC and the workload benefits from the higher density and bandwidth.

Perguntas sobre este artigo

Should I pick the 64GB LRDIMM or a smaller registered DIMM for my server?

The 64GB LRDIMM reduces electrical load on the memory bus, letting you populate more slots per channel than standard registered DIMMs while keeping 3200MHz speed.

What does the PC4-25600 rating deliver in a live system?

It runs at 3200MHz with CL22 latency at 1.2V, and will down-clock automatically to 2933MHz, 2666MHz, 2400MHz or 2133MHz if the platform requires it.

How does the 288-pin LRDIMM interface limit my upgrade path?

The 288-pin DDR4 LRDIMM fits only server and workstation boards that support load-reduced ECC; it cannot be mixed with unbuffered or standard registered modules.
