Server-grade DDR5 ECC kit

This 512GB kit contains sixteen 32GB DDR5 4800 registered DIMMs built for the ASUS RS720-E11-RS24U 2U dual-socket server. Each module runs at 1.1V with CL40 latency and provides error-correcting code protection for mission-critical workloads. The 1Rx4 organisation and 288-pin form factor match the platform's memory subsystem exactly.

Registered ECC with 1Rx4 organisation

The single specification that decides fit is the registered ECC RDIMM design combined with a 1Rx4 rank structure at DDR5 4800 speed. Only modules presenting this exact electrical and logical profile will initialise correctly in the target server's memory controllers. Any deviation in rank, buffering or ECC capability prevents the system from posting.

Sixteen matched modules simplify deployment

The bundle delivers a full 512GB population in one package, eliminating the need to source and validate individual sticks from multiple lots. Matched kits reduce the risk of timing mismatches that can cause intermittent errors under sustained load. No additional software or accessories are included; installation follows the server manufacturer's documented memory-configuration rules.

Questions about this item

How does the 4800 MT/s speed translate once the kit is installed in the ASUS RS720-E11-RS24U server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated throughput when the server's memory controller is set to that speed.

What does the registered ECC RDIMM interface mean for the memory controller in this system?

The 288-pin DDR5 RDIMM presents a registered, ECC-enabled load to the controller, allowing the full 512 GB capacity across 16 modules while maintaining signal integrity.

What physical slot and power requirements must the chassis meet for these 16 modules?

Each 32 GB module uses a standard 288-pin DDR5 RDIMM form factor at 1.10 V and has no heat spreader, so it fits any compatible DIMM slot with adequate airflow.
