OWC 64GB DDR4 ECC RDIMM Kit

This OWC kit delivers 64GB of DDR4 ECC registered memory in two 32GB modules. It runs at 2400MHz with CL17 latency at 1.2V. The 288-pin RDIMM format targets Cisco UCS B200 M4 and C220 M4 servers.

Server and Workstation Upgrade Only

The modules suit administrators expanding Cisco UCS B200 M4 or C220 M4 platforms. They will not work in standard desktop PCs or consumer motherboards. Builders needing unbuffered or load-reduced DIMMs must choose a different product.

Sustained Operation in Qualified Systems

Registered buffering and ECC correction maintain data integrity during continuous server workloads. The 1.2V operation supports stable performance under prolonged demand in compatible Cisco UCS chassis.

Questions about this item

What server models must I already own for this 64GB DDR4 2400 kit to work?

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

Can I add these CL17 2Rx4 modules alongside existing Cisco HXMR1X322RVA sticks?

Yes, they replace those part numbers directly and match the same registered ECC specification.

How do I confirm the 1.2V 288-pin RDIMMs are running at PC4-19200 after installation?

Check the BIOS memory information screen; it should report 2400 MT/s, CL17, registered ECC mode.
