OWC 64GB DDR4 2933MHz PC4-23400 CL21 4Rx4 ECC Load Reduced LRDIMM 1.2V 288-pin server RAM

SKU CH-97T0-6S09A

64GB DDR4 2933MHz ECC Load Reduced LRDIMM for servers, workstations and NAS, backward compatible with 2133, 2400 and 2666MHz

  • Capacity64GB
  • Type288-Pin DDR4 ECC LRDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 64GB

  • ECC error correction protects critical workloads
  • Load-reduced design supports high-capacity server configurations
  • 64GB single module maximises memory density per slot
  • 2933MHz DDR4 speed with backward compatibility to 2666MHz, 2400MHz, 2133MHz
  • JEDEC and RoHS compliant for warranty-safe upgrades

Server-grade ECC LRDIMM

This 64GB DDR4 module is built for servers, workstations and NAS systems that require error-correcting load-reduced memory. It operates at 2933MHz with CL21 latency and 1.2V voltage. The 288-pin 4Rx4 design is not compatible with standard desktop computers or unbuffered memory configurations.

64GB capacity with speed headroom

A single module delivers 64GB of registered ECC capacity for memory-intensive workloads. The PC4-23400 rating runs at 2933MHz while maintaining backward compatibility with 2133MHz, 2400MHz and 2666MHz bus speeds. Systems needing more than 64GB per slot or non-ECC memory will not be served by this module.

288-pin LRDIMM form factor

Installation requires a server or workstation motherboard with DDR4 LRDIMM slots and ECC support. The load-reduced design reduces electrical load on the memory controller, freeing headroom for higher-density configurations. Builds using unbuffered DIMMs, desktop chipsets or mixed rank populations cannot use this memory.

Perguntas sobre este artigo

Will this 64GB DDR4 2933MHz LRDIMM run alongside my existing 2133MHz or 2400MHz server modules?

Yes, the module is backward compatible with 2133MHz, 2400MHz and 2666MHz speeds, so it will operate at the speed of the slowest installed DIMM.

How can I confirm the ECC load-reduced module is detected and error-correcting after installation?

Check the server BIOS or OS memory report for 64GB capacity, 2933MHz speed, ECC enabled status and 4Rx4 organisation on the slot you populated.

Does the single 64GB 288-pin LRDIMM ship with any cables, brackets or software, or must I buy anything else?

Only the memory module is included; no cables, brackets or software are supplied, and no extra parts are required for installation.
