Server ECC RDIMM kit

This OWC kit provides 32 GB of DDR4 ECC registered memory in two 16 GB modules. It is built for Cisco HX220c M4 and HX240c M4 servers that require registered DIMMs with error correction. The modules run at 2400 MT/s with CL17 latency at 1.2 V. Buyers needing standard desktop memory cannot use this product.

Verify registered DIMM support

Confirm that your server accepts 288-pin DDR4 ECC registered RDIMMs and does not require unbuffered or load-reduced modules. The system must support 1Rx4 rank organisation and 1.2 V operation. Mixing this kit with unbuffered or load-reduced memory will prevent the server from posting.

Ready-to-install matched pair

The two modules are factory-matched for multi-channel operation and replace Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG. No heat spreaders are fitted, so airflow in the chassis must be adequate. The kit arrives as a plug-in upgrade with no additional software or cables required.

Questions about this item

What comes in the box and is anything else needed to install it?

The kit contains two 16GB DDR4 2400 ECC registered DIMMs. No extra parts are required for installation in a compatible Cisco server.

Should I choose a different capacity or speed for my Cisco HX220c M4?

This 32GB kit (2 x 16GB) at DDR4 2400 CL17 matches the Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG for the HX220c M4 and HX240c M4.

What does the DDR4 2400 CL17 rating mean once the modules are running in the server?

The modules operate at 2400 MT/s with a CAS latency of 17 cycles at 1.2V, delivering PC4-19200 bandwidth with ECC error correction and registered buffering for stability.
