32 GB DDR5-4800 ECC RDIMM kit

This NEMIX RAM kit delivers 32 GB across two 16 GB DDR5 modules rated at 4800 MT/s with CL40 latency. Registered ECC design provides error correction and signal buffering required by the ASUS S14NA-U12 server board. Modules operate at 1.1 V and use a 288-pin RDIMM form factor.

Suited for ASUS S14NA-U12 upgrades

The kit matches the validated specification for the ASUS S14NA-U12 motherboard, making it a direct fit for administrators expanding memory in that platform. Builders targeting other server boards or workstations should verify their qualified-vendor lists before purchasing. Systems requiring unbuffered memory or non-ECC modules cannot use this registered ECC kit.

Registered ECC with CL40 timing

Registered ECC RDIMM architecture is the single specification that determines compatibility with the ASUS S14NA-U12. The board's memory controller expects registered modules with on-die ECC; unbuffered or non-ECC alternatives will not function. Confirm the platform demands registered ECC before ordering.

Questions about this item

Will the 1.10V DDR5 modules add noticeable heat or power draw when the server runs continuously?

Each module operates at the standard DDR5 voltage of 1.10V, and the registered design reduces electrical load on the memory controller, so sustained operation stays within normal server thermal limits.

Does the ASUS S14NA-U12 board require any specific BIOS setting or firmware revision before these ECC RDIMMs will initialise?

The kit is validated for the ASUS S14NA-U12 server board; follow the board manual to enable ECC in BIOS and apply the latest firmware for full compatibility.

Can the two 1Rx8 registered DIMMs populate the same channel as existing 2Rx8 modules on this platform?

Each DIMM is a single-rank 1Rx8 registered module; the S14NA-U12 memory population rules allow mixing ranks per channel only when the board's qualified-vendor list is followed.
