128GB DDR5 ECC RDIMM kit for ASUS servers

This 128GB kit contains four 32GB registered DDR5 modules built for ASUS server boards such as the S14NA-U12. It targets administrators who need validated, error-correcting memory for mission-critical workloads. Each module runs at 1.10V and carries a CL40 latency rating.

Registered ECC with 1Rx4 organisation

The modules are registered DDR5 RDIMMs with on-die ECC and a 1Rx4 rank structure. This combination provides the signal integrity and error detection required by multi-socket server platforms. The 288-pin form factor matches the DDR5 slots on the qualified ASUS motherboard.

128GB total capacity at DDR5-4800

The kit delivers 128GB of bandwidth at 4800 MT/s (PC5-38400), suitable for virtualisation, database caching and high-thread-count compute. Workloads that exceed 128GB or demand speeds beyond 4800 MT/s will require additional DIMM slots or faster-rated modules.

Highlights

Questions about this item

What does the 4800 MT/s speed mean once the kit is installed in an ASUS S14NA-U12 server?

The modules run at DDR5 4800 MT/s, delivering PC5 38400 bandwidth per module; the server's memory controller determines the final operating speed based on how many DIMM slots are populated.

How does the PC5 38400 rating limit real-world throughput?

PC5 38400 defines the module's maximum data rate at 4800 MT/s; sustained throughput is governed by the ASUS server's memory-channel configuration and the registered ECC protocol overhead.

What physical clearance does the 288-pin RDIMM kit need inside the chassis?

Each 32 GB stick is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so it fits any ASUS S14NA-U12 DIMM slot that accepts registered ECC modules.
