Server memory kit

This NEMIX RAM kit provides 256GB of DDR5 4800 ECC registered memory across eight 32GB modules. It is built for the ASUS RS720-E11-RS24U 2U dual-socket server and runs at 1.10V with CL40 latency.

Ideal for IT teams expanding capacity

The kit suits administrators who need validated, high-density registered DIMMs for this specific ASUS platform. It is not for builders using consumer motherboards, non-ECC memory or systems that require unbuffered modules.

Check your server configuration

Confirm the RS720-E11-RS24U has eight free DDR5 RDIMM slots and that the BIOS supports 1Rx4 registered modules at 4800 MT/s. Verify the memory population rules for dual-socket operation before installation.

Questions about this item

What server must I already own to use this 8×32GB 288‑pin DDR5 4800 CL40 ECC RDIMM kit?

The kit is validated for the ASUS RS720‑E11‑RS24U 2U dual‑socket server; install all eight modules into that chassis to reach the full 256GB capacity.

Can I keep older DDR5 ECC RDIMMs installed alongside these 1Rx4 CL40 modules in the same ASUS RS720‑E11‑RS24U?

Mixing ranks or speeds is not recommended; for stable operation populate all eight slots with identical 32GB 1Rx4 4800MT/s modules.

How do I verify the kit runs at 4800MT/s CL40 1.10V after installation?

Enter the BIOS on the ASUS RS720‑E11‑RS24U and confirm the memory frequency shows 4800MT/s, CAS latency 40 and voltage 1.10V.
