Server-grade DDR5 ECC RDIMM kit

This 64GB kit contains four 16GB registered DDR5 modules built for the ASUS RS520A-E12-RS24U 2U server. It delivers error-correcting memory for mission-critical workloads in a single-socket platform. IT professionals select it when data integrity and validated compatibility are mandatory.

Registered DDR5 4800 with CL40 latency

Each module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.10V. The 1Rx8 organisation and registered buffer reduce electrical load on the memory controller. This exact speed, voltage and latency combination is the specification that determines whether the kit matches the server's qualified vendor list.

Tool-free DIMM installation with population rules

The 288-pin RDIMMs seat vertically in the server's memory slots without tools; the kit ships as a matched set of four. Installation fails when modules are mixed with unbuffered or non-ECC DIMMs, or when the population sequence in the service manual is ignored. Buyers who need unregistered memory or consumer DDR5 speeds cannot use this kit.

Questions about this item

What does the DDR5 4800 speed rating mean once the modules are installed in the ASUS RS520A-E12-RS24U server?

The modules will run at 4800 MT/s, delivering PC5-38400 bandwidth per module for registered ECC workloads on this specific platform.

How does the 288-pin RDIMM interface affect usable capacity and registration in this server?

The 288-pin DDR5 RDIMM interface provides registered buffering and on-die ECC, allowing the 64GB kit to operate as four 1Rx8 ranks per channel.

What physical slot requirements must the RS520A-E12-RS24U meet to accept this 4-module kit?

The server needs four available 288-pin DDR5 RDIMM slots to install the four 16GB modules included in this kit.
