OWC 128GB DDR4 3200 CL22 4Rx4 288-pin ECC LRDIMM 1.2V memory upgrade

SKU CH-ZPCN-ZEMDR

128 GB DDR4 3200 ECC load-reduced LRDIMM for Gigabyte G292-Z44, G292-Z45, G292-Z46, G482-Z51 and G482-Z52 servers

  • Capacity128GB
  • Type288-Pin DDR4 ECC LRDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS Latency22
  • Voltage1.2V
  • ECCYes

Capacity 128GB

Struck-through versions exist but are not stocked here.

  • 128 GB capacity expands server memory headroom
  • ECC load-reduced design maintains data integrity under load
  • DDR4 3200 CL22 at 1.2 V balances speed and efficiency
  • Validated for Gigabyte G292 and G482 server platforms
  • Backward compatible with 2133, 2400, 2666 and 2933 MHz systems

Server-grade ECC LRDIMM upgrade

This 128GB DDR4 3200 module uses a 4Rx4 load-reduced design with ECC for Gigabyte G292 and G482 server platforms. It operates at 1.2V with CL22 latency and fits 288-pin DIMM slots. The part targets administrators expanding memory in compatible workstation and NAS systems.

Replaces slower DDR4 or smaller LRDIMMs

The module is backward compatible with 2133, 2400, 2666 and 2933MHz bus speeds, so it can upgrade existing configurations running at those rates. It cannot be mixed with unbuffered or registered ECC DIMMs, so a full replacement is required when changing memory types. The jump is worthwhile when the platform supports load-reduced topology and needs maximum per-slot density.

Handles large virtualisation and database workloads

A single 128GB stick provides substantial headroom for multi-tenant virtualisation, in-memory databases and high-thread-count compute tasks on supported Gigabyte servers. Capacity runs out when the application working set exceeds the total installed memory across all populated slots, or when the platform's maximum memory limit is reached.

Questions about this item

Does the 288-pin LRDIMM fit the DIMM slots on a Gigabyte G292-Z44?

Yes, the 288-pin DDR4 ECC Load Reduced DIMM matches the slot keying and form factor for the listed Gigabyte G292-Z44, G292-Z45, G292-Z46, G482-Z51 and G482-Z52 servers.

What is the correct installation step for the 4Rx4 128 GB module that people often miss?

Install only LRDIMM modules — do not mix with unbuffered or ECC registered DIMMs — and populate slots per the server manual to enable the 4Rx4 organisation at 1.2 V.

When will the 128 GB DDR4 3200 CL22 module need replacement?

The JEDEC-standard DDR4 LRDIMM is rated for continuous server operation; replace only if memory diagnostics report correctable ECC errors rising above threshold or a hard failure occurs.
