64GB DDR5 4800 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 4800 registered DIMMs built for the ASUS S14NA-U12 server board. Each module runs at 1.1V with CL40 latency and uses a 1Rx4 organisation. ECC and registered buffering provide the data-integrity features required in server environments.

Suited for ASUS S14NA-U12 memory upgrades

Administrators expanding an ASUS S14NA-U12 platform to 64GB with matched, tested modules will find this kit compatible. Builders needing non-ECC UDIMMs, different speeds, larger single-module capacities or support for other motherboards should look elsewhere.

Two matched 32GB modules in the package

The box delivers a paired 2x32GB kit so the system can run in dual-channel mode without manual matching. No heat spreaders, additional software or cables are included; the modules install directly into the 288-pin DDR5 slots.

Questions about this item

Does the ASUS S14NA-U12 motherboard need to support DDR5 4800 ECC RDIMM for this 64GB kit to work?

Yes, the board must accept DDR5 4800 PC5-38400 registered ECC modules; the kit is built specifically for that platform.

Can I run these 1.1V 1Rx4 modules alongside older DDR5 ECC RDIMMs that operate at a different voltage?

All modules in a server must share the same 1.1V supply; mixing voltages will prevent the system from posting.

How can I confirm the 64GB kit is recognised at 4800 MT/s with ECC active after installation?

Check the BIOS memory information or run a hardware inventory tool; it should show 64GB at 4800 MT/s with ECC enabled.
