Server memory upgrade for Cisco HX220c M4

This OWC module adds 16GB of DDR4 ECC registered memory to compatible Cisco servers. It is built for workstation and server platforms that require registered DIMMs with error correction. The single 1Rx4 rank module installs in a standard 288-pin DDR4 slot and operates at 1.2V.

DDR4 2400 registered ECC limits

The PC4-19200 standard caps transfer rates at 2400 MT/s with CL17 latency. Registered buffering adds one clock cycle of delay versus unbuffered memory but allows higher total capacities per channel. Mixing this module with unbuffered or load-reduced ECC DIMMs is not supported and will prevent the system from booting.

Replaces Cisco UCSMR1X161RVA

This module directly substitutes the listed Cisco part numbers in HX220c M4 and HX240c M4 servers. The upgrade is worthwhile when expanding memory capacity for virtualization or database workloads that exceed the current installed amount. It is not suitable for standard desktop computers or any platform that requires unbuffered memory.

Questions sur cet article

Should I choose the 16 GB module or add multiple sticks for my Cisco HX220c M4?

Each module provides 16 GB of DDR4 2400 ECC Registered memory; add as many sticks as your server's DIMM slots and maximum capacity allow.

What does the DDR4 2400 CL17 rating mean once the module is installed in a Cisco HX240c M4?

The module runs at 2400 MT/s with a CAS latency of 17 cycles, delivering PC4-19200 bandwidth for server workloads.

Will the 288-pin ECC Registered RDIMM work with standard desktop motherboards?

No — this DDR4 2400 CL17 Registered DIMM is designed for Cisco HX220c M4 and HX240c M4 servers and is not compatible with unbuffered desktop platforms.
