Server Memory Upgrade

This 64GB DDR5 module is built for the ASUS RS720-E11-RS12U 2U dual-socket server. It delivers registered ECC operation at 4800MHz with a CL40 latency profile. The single DIMM format suits administrators expanding capacity in mission-critical environments.

Registered ECC Stability

Registered signalling and on-die ECC protect data integrity across heavy workloads. The 2Rx4 organisation and 1.1V voltage align with the platform memory controller requirements. No heat spreader is fitted, relying on chassis airflow for thermal management.

288-Pin RDIMM Form Factor

The standard 288-pin DDR5 RDIMM keying ensures correct insertion in compatible server slots. Samsung, Micron or Hynix major-OEM chips provide supply-chain consistency. Buyers needing non-ECC unbuffered memory or desktop SO-DIMM modules should look elsewhere.

Questions about this item

Will the 2Rx4 DDR5 RDIMM need any firmware updates or component swaps during its service life?

The module is a standard JEDEC DDR5 4800 2Rx4 registered DIMM; no firmware updates or component replacements are required once it is installed in the ASUS RS720-E11-RS12U server.

What limit appears first when the 64 GB module runs at 4800 MT/s continuously in a 2U chassis?

The primary limit is thermal — the module has no heat spreader and operates at 1.10 V, so sustained full-speed loads are constrained by the server's airflow and DIMM-slot cooling capacity.

How much power does the 1.10 V 64 GB DDR5 RDIMM draw and how hot does it get under all-day load?

At 1.10 V the module draws roughly 8–10 W typical; without a heat spreader it relies on chassis airflow, so DIMM temperatures will track the server's inlet temperature plus the local airflow rise.
