Cisco Server Compatible 64GB DDR5 RDIMM

This NEMIX RAM module provides 64GB of DDR5 4800 registered ECC memory for Cisco servers. It operates at 1.1V with CL40 latency and uses a 2Rx4 rank configuration on a 288-pin form factor. The part is validated for Cisco UCSX-MRX64G2RE1 systems.

Suited for IT teams expanding Cisco server capacity

Administrators who need registered ECC modules for compatible Cisco platforms will find this module fits the qualified parts list. It is not intended for desktop motherboards, consumer laptops, or any system that requires unbuffered non-ECC memory.

Handles large virtualisation and database workloads

The 64GB density gives ample headroom for multi-VM hosts and in-memory databases running on supported Cisco hardware. Single-module upgrades beyond this capacity are not covered by this part number, so denser configurations require additional qualified modules.

Questions about this item

Does this 288-pin DDR5 RDIMM require a Cisco server motherboard that supports registered ECC memory?

Yes, this module is a registered ECC DDR5 RDIMM built for Cisco systems; the host motherboard must accept 288-pin DDR5 registered ECC DIMMs for it to function.

Can I mix this CL40 4800 module with slower DDR5 DIMMs already installed in the same server?

The server will run all populated channels at the speed of the slowest installed DIMM, so mixing with slower DDR5 modules will lower the overall memory frequency.

After installation, how can I confirm the module is recognised at its rated 4800 speed and CL40 timing?

Check the system BIOS or UEFI memory information screen; it should report a single 64 GB DDR5 4800 MT/s module with CAS latency 40 operating at 1.1 V.
