OWC 128GB DDR4 2400MHz CL17 4Rx4 ECC LRDIMM 1.2V 288-pin server RAM

SKU CH-9RHG-VYA37

A single 128 GB DDR4 2400 MHz CL17 ECC load-reduced DIMM for servers, workstations and NAS systems, backward compatible with 2133 MHz

  • Capacity128GB
  • Type288-Pin DDR4 ECC LRDIMM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.2V
  • ECCYes

Capacity 128GB

  • 128GB single module maximises server density
  • ECC load-reduced design protects data integrity in critical workloads
  • DDR4 2400MHz CL17 at 1.2V balances speed and power efficiency
  • 288-pin LRDIMM fits server, workstation and NAS platforms
  • JEDEC and RoHS compliant for warranty-safe upgrades

Server memory upgrade

This 128GB DDR4 LRDIMM module targets administrators expanding capacity in compatible servers, workstations and NAS systems. It delivers error-correcting, load-reduced operation at 2400MHz with a CL17 latency profile.

Build integration

The 288-pin registered design requires a platform that supports DDR4 ECC load-reduced memory and cannot be mixed with unbuffered modules. A single stick adds 128GB, freeing remaining slots for further expansion while operating at the standard 1.2V.

Upgrade context

It replaces lower-capacity DDR4 LRDIMMs or upgrades systems running at 2133MHz, with backward compatibility ensuring stable operation. The jump is worthwhile when maximum density per slot is needed and the platform validates 4Rx4 registered ECC modules.

Perguntas sobre este artigo

How does the 4Rx4 rank configuration affect maximum capacity per channel under sustained load?

The quad-rank 4Rx4 organisation lets a single 128 GB module populate one slot, so fewer DIMMs are needed to reach high densities per channel.

What is the typical power draw and thermal output of this 1.2 V LRDIMM during continuous operation?

At 1.2 V the module runs at standard DDR4 voltage; load-reduced buffering lowers electrical load on the memory bus, reducing heat compared to registered DIMMs of similar capacity.

Which server or workstation platforms already support 288-pin DDR4 ECC LRDIMMs at 2400 MHz?

Any system qualified for PC4-19200 288-pin ECC load-reduced DIMMs — including backward-compatible 2133 MHz platforms — will accept this module.
