Cisco HX240c M5 DDR4 ECC RDIMM

This 16 GB DDR4 2933 MHz module is built for the Cisco Hyperflex HX240c M5 server. It delivers registered ECC reliability for mission-critical workloads in enterprise environments.

Upgrade from lower-capacity or non-ECC memory

Replacing smaller RDIMMs or unbuffered modules adds 16 GB per slot with full error correction. The jump is worth it when uptime and data integrity outweigh raw speed gains.

16 GB single-rank headroom

One 1Rx4 module at 1.2 V fills a single 288-pin slot and supports typical virtualization densities. Capacity runs out when the platform requires more than the installed DIMM count allows.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the Cisco HX240c M5 memory slots?

Yes, the 288-pin DDR4 RDIMM form factor matches the Cisco HX240c M5 DIMM slots.

What is the correct orientation step when installing this registered ECC module?

Align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, and verify the module sits evenly.

When should the 1Rx4 16GB ECC RDIMM be replaced in a Cisco HX240c M5 server?

Replace the module if the server logs uncorrectable ECC errors, fails memory diagnostics, or shows persistent instability under load.
