Server memory kit

This NEMIX RAM kit provides 32 GB of DDR5 4800 ECC registered memory in a matched pair of 16 GB modules. It is built for the ASUS RS720-E11-RS24U 2U dual-socket server and runs at 1.1 V with CL40 latency.

Who this suits

IT teams upgrading compatible ASUS servers for virtualization, databases or ECC-dependent workloads will benefit from the registered design and validated compatibility. Builders needing unbuffered DIMMs, non-ECC memory or support for other platforms should look elsewhere.

Build integration

The 288-pin RDIMMs install directly into the server's DDR5 slots and draw 1.1 V, leaving headroom within the platform's power budget. No heat spreaders are fitted, so airflow across the modules must be maintained by the chassis fans.

Questions about this item

My ASUS RS720-E11-RS24U server has empty DDR5 RDIMM slots — will this 288-pin kit install directly?

Yes, the kit is built for that model. Each module is a 288-pin DDR5 RDIMM keyed for the server's registered memory slots.

Can I keep my existing 1Rx8 registered DDR5 modules in the other channels while adding this 32 GB kit?

The modules are 1Rx8 registered DDR5 at 4800 MT/s and 1.1 V. They will share the memory bus with identical-rank registered DDR5 DIMMs, though the system will run all channels at the slowest common speed and timing.

After seating both 16 GB sticks, what BIOS indication confirms they are running as a 32 GB registered ECC kit at 4800 MT/s?

POST memory count should show 32 GB total, the memory configuration screen must report ECC enabled and registered mode active, and the rated speed should read 4800 MT/s with CL40 timings.
