Server memory kit

This OWC kit supplies 512GB of DDR4 2400 ECC load-reduced memory in eight 64GB modules for Cisco UCS B200 M4 and C220 M4 servers. It runs at PC4-19200 with CL17 latency and 1.2V operation. The 288-pin LRDIMMs use 4Rx4 organisation to maximise capacity per slot.

Suits Cisco UCS upgrades

IT teams refreshing B200 M4 or C220 M4 blades can install this kit to reach the platforms' higher memory ceilings. The modules are not compatible with standard desktops or unbuffered and registered ECC memory types. Buyers needing non-ECC or consumer DIMMs should look elsewhere.

Eight matched modules

The package contains eight identical 64GB LRDIMMs tested together for multi-channel stability. No heat spreaders are fitted, relying on server airflow. Backward compatibility with 2133MHz systems allows deployment in mixed-speed configurations without additional parts.

Questions about this item

What Cisco UCS server models must I already own for this 512GB LRDIMM kit to work?

This kit is validated for Cisco UCS B200 M4 and C220 M4 servers only.

How will these 2400MHz CL17 modules behave if I keep 2133MHz DIMMs in the same server?

The modules support backward compatibility with 2133MHz speeds, but LRDIMM memory cannot be mixed with unbuffered or registered ECC DIMMs.

How can I confirm the 8x64GB kit is running at the correct 2400MHz CL17 speed after installation?

Check the server BIOS or management console to verify DDR4-2400 operation and CL17 timings on all eight slots.
