256GB DDR5 ECC RDIMM kit

This 256GB kit contains sixteen 16GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It operates at 1.1V and uses a 288-pin form factor designed for server motherboards. The modules are validated for the ASUS RS720-E11-RS24U 2U dual-socket server.

Compatibility and use-case limits

The kit targets administrators upgrading the named ASUS 2U platform or matching its exact memory specification. It is not for desktop PCs, workstations using unbuffered memory, or systems that require a different speed, voltage, pin count or rank configuration.

Registered ECC with 1Rx8 organisation

Each module is a single-rank 1Rx8 registered ECC RDIMM, a requirement for the target server's memory controller. Buyers must confirm their platform accepts registered ECC RDIMMs with this rank structure before purchasing.

Questions about this item

What does the 4800 MHz speed mean once the kit is installed in the ASUS RS720-E11-RS24U server?

The modules run at DDR5 4800 MT/s, delivering PC5-38400 bandwidth for the server's memory subsystem.

How does the 288-pin DDR5 RDIMM interface limit performance in this 2U dual-socket platform?

The registered DDR5 RDIMM interface operates at 1.10 V with CL40 latency, capping throughput to the DDR5 4800 standard supported by the platform.

What physical space and slot arrangement does the 16-module kit require inside the chassis?

The kit contains sixteen 288-pin DDR5 RDIMMs that must populate the server's DIMM slots according to the motherboard's population rules.
