System-specific DDR5 ECC RDIMM kit

This 512 GB kit contains 16 registered DDR5 modules at 4800 MT/s with ECC and a CL40 latency. It is built for the ASUS RS720A-E12-RS24U 2U dual-processor server and runs at 1.10 V on a 288-pin interface.

Upgrade path for compatible ASUS servers

The kit replaces lower-capacity DDR5 RDIMM sets in the same platform when workloads demand the full 512 GB across 16 slots. The jump is worth it when virtualisation density, in-memory databases or large dataset processing exceed the current memory ceiling.

DDR5 RDIMM platform limits

Registered DDR5 at 4800 MT/s scales to the slot count and memory-controller limits of the RS720A-E12-RS24U motherboard. Bandwidth and capacity beyond this kit depend on the server's processor generation and chipset, which define the maximum supported memory per socket.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the ASUS RS720A-E12-RS24U 2U server chassis?

Yes, the 288-pin DDR5 RDIMM form factor matches the memory slots on the ASUS RS720A-E12-RS24U 2U dual-processor server.

What is the correct order to populate the 16 modules across both processors?

Follow the ASUS motherboard manual for the RS720A-E12-RS24U; populate slots per CPU in the sequence shown to enable all memory channels.

When should the registered ECC modules be replaced if correctable errors increase?

Monitor the IPMI or OS logs for rising correctable ECC counts; replace affected 32 GB modules before uncorrectable errors appear.
