OWC 64GB DDR4 2400 PC4-19200 CL17 4Rx4 288-pin 1.2V ECC Load Reduced LRDIMM for Cisco UCS C240 M4

SKU CH-G7TP-1AAP2

A 64GB DDR4 2400 ECC load-reduced DIMM with CL17 latency and 1.2V operation, designed for Cisco UCS C240 M4 servers

  • Total capacity64 GB
  • Rated speedDDR4 2400 (PC4 19200)
  • CAS latencyCL17
  • Rated voltage1.2 V
  • Buffer typeLoad Reduced
  • Memory rank4Rx4

Capacity 64GB

  • 64 GB capacity maximises server memory density
  • ECC load-reduced design protects data integrity in critical workloads
  • DDR4 2400 PC4-19200 speed matches Cisco UCS C240 M4 specifications
  • Single 4Rx4 module simplifies upgrade without mixing ranks
  • 2 V operation reduces power draw compared to higher-voltage alternatives

Server Memory Upgrade

This 64GB DDR4 ECC Load Reduced DIMM is built for the Cisco UCS C240 M4 server. It delivers registered error-correcting memory for workloads that require data integrity and high capacity in a single module.

Compatibility Check

Verify your system is a Cisco UCS C240 M4 and that existing memory slots use Load Reduced ECC DIMMs. This module cannot be mixed with unbuffered or standard registered ECC memory and will not work in desktop computers.

Thermals and Power

The module operates at 1.2V without a heat spreader, relying on server chassis airflow for cooling. Power draw scales with the 2400MHz speed and 4Rx4 organisation, producing typical noise levels for passively cooled server memory.

Questions about this item

Does the OWC 64GB DDR4 2400 module ship alone or as part of a kit, and are any extra parts needed for installation?

The upgrade consists of a single 64GB LRDIMM; no additional components are required for installation in a compatible Cisco UCS C240 M4 server.

Should I choose the 2400MHz CL17 LRDIMM or a lower-speed alternative for my Cisco UCS C240 M4?

This 64GB DDR4 2400 PC4-19200 CL17 LRDIMM is the specified upgrade; it also runs at 2133MHz if the system requires that speed.

What real-world performance does the PC4-19200 2400MHz rating deliver once the module is installed in the Cisco UCS C240 M4?

The module operates at 2400MHz with CL17 latency and 1.2V, providing ECC load-reduced reliability for server workloads in the C240 M4.
