Purpose-built server memory kit

This OWC kit provides 512GB of DDR4 ECC Load Reduced memory across four 128GB modules. It is designed for Cisco UCS B200 M6, C125 M5, C220 M6, C240 M6 and C245 M6 servers that require 288-pin LRDIMMs. The modules run at 3200MHz with CL22 latency and operate at 1.2V.

Suited for qualified Cisco UCS platforms

IT teams maintaining the listed Cisco UCS models can use this kit to maximise installed memory within the supported configuration. It will not work in standard desktop computers, consumer workstations or any system that accepts only unbuffered or registered ECC DIMMs. Mixing with those module types is not supported.

512GB capacity with backward speed compatibility

The four-module kit delivers 512GB total capacity for memory-intensive virtualisation, database or analytics workloads on the compatible Cisco servers. Modules also operate at 2133MHz, 2400MHz, 2666MHz and 2933MHz when the platform requires a lower speed. Systems needing higher density per slot or a different form factor cannot use this kit.

Questions about this item

Which Cisco UCS servers must I already own for this 512GB DDR4 3200 LRDIMM kit to be compatible?

This kit is validated for Cisco UCS B200 M6, C125 M5, C220 M6, C240 M6 and C245 M6 servers; it will not work in standard desktops or other platforms.

Can I keep my existing 2133MHz, 2400MHz, 2666MHz or 2933MHz DDR4 ECC LRDIMMs and add these 3200MHz modules alongside them?

Yes, the modules are backward compatible with those speeds, but all installed DIMMs must be ECC Load Reduced — mixing with unbuffered or registered ECC memory is not supported.

After installation, how can I confirm the 4Rx4 128GB modules are running at 3200MHz CL22 with ECC active?

Check the server BIOS or Cisco UCS Manager memory inventory; it should show each DIMM at 512GB total, 3200 MT/s, CL22, 1.2 V, ECC Load Reduced and 4Rx4 organisation.
