Server Memory Kit

This OWC upgrade kit supplies 64GB of DDR4 ECC Registered memory in two 32GB modules. It is built for the Cisco UCS C240 M4 server and operates at 2400MHz with CL17 latency and 1.2V power draw.

Registered ECC Design

The modules use a 2Rx4 registered architecture with on-board error correction. This configuration prevents data corruption in multi-socket workloads but cannot be mixed with unbuffered or load-reduced DIMMs in the same system.

Compatibility Check

Verify that your Cisco UCS C240 M4 currently supports registered ECC RDIMMs and has two free 288-pin slots. This kit will not work in standard desktop motherboards or in systems that require unbuffered or load-reduced memory.

Questions sur cet article

Will the registered ECC DIMMs need any firmware or heat-spreader maintenance later?

No firmware updates are required; the modules have no heat spreader and run at the standard 1.2 V, so they need no special maintenance beyond normal server cleaning.

What limits sustained throughput on the Cisco UCS C240 M4 with these 2400 MHz CL17 modules?

The memory controller caps bandwidth at the rated 2400 MT/s PC4-19200 speed; latency is fixed at CL17, so sustained loads cannot exceed that ceiling.

How much heat and power do the two 32 GB 2Rx4 sticks add when the server runs all day?

Each 1.2 V DDR4 RDIMM draws only a few watts under load, producing minimal extra heat that the C240 M4's standard airflow handles without additional cooling.
