OWC 64GB DDR5 4800 ECC RDIMM CL40 2Rx4 1.1V Gigabyte Server Memory Upgrade

SKU CH-W40A-KHZ6A

A single 64 GB DDR5 4800 ECC registered RDIMM at 1.1 V for Gigabyte G293-Z42, G293-Z43, G363-ZR0, G493-ZB0 and G493-ZB1 servers

  • Capacity64GB
  • Type288-Pin DDR5 ECC RDIMM
  • SpeedDDR5 4800 (PC5 38400)

  • Voltage1.1V
  • ECCYes

Capacity 64GB

  • 64 GB single module doubles server capacity
  • DDR5 4800 PC5-38400 CL40 meets JEDEC standard
  • ECC registered 2Rx4 protects data integrity in critical workloads
  • 1 V operation reduces power draw per module
  • Validated for Gigabyte G293-Z42 G293-Z43 G363-ZR0 G493-ZB0 G493-ZB1

Targeted Server Upgrade

This 64GB DDR5 ECC Registered DIMM is built for Gigabyte G293-Z42, G293-Z43, G363-ZR0, G493-ZB0 and G493-ZB1 platforms. It serves administrators who need to expand memory capacity in compatible workstations, NAS systems or network switches.

JEDEC-Compliant Registered Design

The module operates at 4800MHz with CL40 latency and 1.1V voltage in a 288-pin form factor. Its 2Rx4 registered architecture provides signal integrity for multi-DIMM configurations, while ECC corrects single-bit errors to protect data integrity in continuous-operation environments.

Capacity Step for Existing Infrastructure

Adding this single 64GB stick increases total system memory without replacing populated slots, extending the service life of deployed servers. The jump is worthwhile when workloads exceed current RAM limits and the platform supports registered ECC DDR5; it will not function in standard desktop boards or alongside unbuffered or load-reduced modules.

Perguntas sobre este artigo

Does the DDR5 4800 PC5-38400 interface cap at CL40 latency?

Yes, this module runs at DDR5 4800 with a CAS latency of CL40 as specified by JEDEC PC5-38400.

What slot and form factor does the 288-pin RDIMM need?

It requires a standard 288-pin DDR5 RDIMM slot on a Gigabyte G293-Z42, G293-Z43, G363-ZR0, G493-ZB0 or G493-ZB1 server board.

How is the ECC Registered DIMM installed and what step is often missed?

Align the notch, press firmly until the retention clips click, then verify the BIOS recognises the 64GB 2Rx4 module at 1.1V.
