1.5 TB DDR5 ECC RDIMM Kit

This 1.5 TB kit contains twelve 128 GB DDR5 4800 CL40 registered DIMMs built for the ASUS RS720A-E12-RS12 dual-processor server. ECC and registered buffering protect data integrity in mission-critical workloads. The modules run at 1.1 V and use 4Rx4 organisation for maximum density.

288-pin DDR5 server form factor

Each module fits a standard 288-pin DDR5 RDIMM slot and requires a platform that supports registered ECC memory at 4800 MT/s. The kit populates twelve slots, freeing the installer from mixing capacities or speeds. No heat spreader is fitted, so airflow in the chassis must be sufficient for dense population.

12 x 128 GB capacity headroom

The 1.5 TB total suits large-scale virtualisation, in-memory databases and heavy compute clusters. CL40 latency and 4800 MT/s throughput match the platform specification. Workloads needing higher frequencies, lower latencies or non-ECC operation will not be served by this registered kit.

Questions about this item

What happens when the 4Rx4 rank density hits the memory controller limit under sustained load?

The 4Rx4 organisation across twelve 128GB modules presents maximum rank density to the controller; sustained throughput is governed by the DDR5 4800 CL40 timing at 1.10V.

How much heat does the 1.5TB kit add when the server runs all day?

Twelve registered DDR5 modules at 1.10V without heat spreaders rely on chassis airflow; power draw scales with the 4800 MT/s data rate and 4Rx4 density.

Which ASUS 2U dual-processor server must already be in the rack for this kit to work?

The memory is validated for the ASUS RS720A-E12-RS12 platform; the motherboard must support 288-pin DDR5 RDIMM at 4800 MT/s with ECC.
