64 GB DDR5 ECC RDIMM kit for ASUS S14NA-U12

This NEMIX RAM kit delivers 64 GB of DDR5 4800 registered ECC memory in four 16 GB modules. It is built for the ASUS S14NA-U12 server board and runs at 1.1 V with CL40 latency. The 288-pin RDIMM form factor and 1Rx8 organisation suit enterprise workloads that require error correction and registered buffering.

Suited to administrators expanding the ASUS

The kit matches the board's qualified DDR5 4800 registered ECC specification, so it fits directly into the four available slots. Builders who need unbuffered UDIMM modules, non-ECC memory, or a different speed grade should look at other memory types because this product is registered ECC only.

Four matched modules simplify population

The package contains four identical 16 GB sticks, eliminating the need to mix capacities or ranks during installation. Pre-tested matching reduces the chance of timing mismatches and lets the server board initialise the full 64 GB array without manual configuration.

Questions about this item

What motherboard must I already have to install these four 16 GB DDR5 4800 CL40 ECC RDIMM modules?

They are validated for the ASUS S14NA-U12 server board; the board must support 288-pin DDR5 RDIMM slots and registered ECC memory at 1.1 V.

How do these 1.1 V registered DDR5 modules behave alongside older DDR5 DIMMs I keep in the same server?

All slots must run at the same voltage and speed; mixing different DDR5 speeds or ranks will force the system to the lowest common setting.

How can I confirm the kit is running at the rated 4800 MT/s and CL40 after installation?

Check the BIOS memory information or a tool such as CPU-Z to verify DDR5-4800 frequency and CAS latency 40 on all four modules.
