384GB DDR5 ECC RDIMM server kit

This NEMIX RAM kit delivers 384GB across six 64GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for ASUS server boards such as the S14NA-U12 that require 2Rx4 registered memory at 1.10V. The modules use major OEM chips from Samsung, Micron or Hynix and ship without heat spreaders.

Check board slots and CPU memory channels

Verify that your ASUS server motherboard has at least six DDR5 RDIMM slots and supports 4800 MT/s registered ECC memory at 1.10V. Confirm the CPU populated on the board provides enough memory channels for a six-module population. Consult the board manual for the exact slot-filling order required for 384GB capacity.

Replaces smaller RDIMM sets or mixed-capacity kits

This kit upgrades systems running lower-capacity registered DDR5 kits or mismatched modules that limit total memory and channel balance. The jump is worth it when workloads need the full 384GB at native 4800 speed with consistent 2Rx4 rank layout across all channels. It is not for boards limited to UDIMM or non-ECC memory.

Questions about this item

What does the package content include and is anything else required for installation?

The kit contains six 64 GB DDR5 4800 CL40 ECC registered DIMMs for a total of 384 GB; no additional parts are needed beyond a compatible ASUS server board with 288-pin DDR5 slots.

How do I decide between this 384 GB kit and a smaller capacity option?

Choose this 6 x 64 GB kit when the workload demands the maximum supported memory for the ASUS S14NA-U12; select a lower-capacity kit if the application fits in less memory and you want to leave slots free for future expansion.

What does the PC5-38400 rating mean for real-world performance in a server?

PC5-38400 is the JEDEC designation for DDR5 4800 memory, indicating the modules run at 4800 MT/s with CL40 latency and 1.10 V, delivering the standard bandwidth and error-correction required for registered server workloads.
