OWC 2R4D42R432GB 32GB DDR4 2400 CL17 2Rx4 288-pin 1.2V ECC Registered RDIMM for Cisco UCS C240 M4

SKU CH-QBZD-5D4NV

32 GB DDR4-2400 ECC registered RDIMM, CL17 at 1.2 V, built for the Cisco UCS C240 M4 server

  • Capacity32GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.2V
  • ECCYes

Capacity 32GB

  • ECC registered design protects data integrity in server workloads
  • 32 GB capacity expands memory headroom for virtualisation
  • DDR4 2400 speed matches Cisco UCS C240 M4 specifications
  • 2Rx4 dual-rank organisation optimises channel density
  • 2 V operation reduces power draw per module

Targeted Server Upgrade

This OWC module delivers 32GB of DDR4 ECC registered memory rated at 2400MHz with CL17 latency. It is built specifically for the Cisco UCS C240 M4 server platform and operates at 1.2V using a 2Rx4 rank configuration.

Replaces Cisco Parts

The DIMM replaces Cisco part numbers including HXMR1X322RVA and UCSMR1X322RVA. The upgrade is worthwhile when expanding capacity in supported Cisco UCS C240 M4 chassis or when a registered ECC module is required to maintain system stability.

Verify Registered ECC Requirement

Confirm the server requires registered ECC RDIMMs and cannot accept unbuffered or load-reduced variants. Ensure the memory slots accept 288-pin DDR4 modules and that the existing configuration supports 2Rx4 rank population rules.

Soalan tentang produk ini

Will this 288-pin DDR4 RDIMM fit the memory slots on a Cisco UCS C240 M4 server?

Yes, the module is a 288-pin DDR4 ECC Registered DIMM built specifically for the Cisco UCS C240 M4 platform.

What is the correct way to seat this registered ECC module, and what step do installers often miss?

Align the notch on the 288-pin edge connector with the slot key, press firmly until both side latches click, and verify the BIOS recognises the full 32 GB capacity.

When should this 32 GB DDR4 2400 CL17 RDIMM be replaced in a production server?

Replace the module if memory diagnostics report correctable or uncorrectable ECC errors, or if the server fails to POST with the DIMM installed.
