System-Specific DDR5 RDIMM Kit

This 384 GB kit contains six 64 GB DDR5 ECC RDIMM modules built for the Supermicro SuperServer SYS-822GS-NB3RT. Registered buffering and on-die ECC protect data integrity in multi-socket server workloads. The kit runs at 6400 MHz with CL52 latency at 1.1 V.

Installation Notes

Modules use the standard 288-pin DDR5 RDIMM form factor and seat in the server’s DIMM slots without tools. Populate all six channels identically to maintain balanced memory interleaving. Mismatched ranks or mixed speeds will prevent the system from posting.

Suitability Guidance

Ideal for administrators expanding the SYS-822GS-NB3RT to its maximum supported capacity with validated registered ECC memory. Buyers needing non-ECC UDIMMs, lower-density modules, or memory for a different platform should look elsewhere.

Questions about this item

How can I confirm the 384GB kit is running at 6400MHz CL52 after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 6400MHz with timings showing CL52; the server POST screen will also list the total 384GB detected across all six slots.

What exactly ships in the box and do I need any extra parts for the Supermicro SYS-822GS-NB3RT?

The package contains six 64GB 288-pin DDR5 ECC RDIMM modules; no additional brackets, cables or cooling are required for this server model.

Which capacity version should I choose if I want the full 384GB supported by the SYS-822GS-NB3RT?

Select the 384GB (6×64GB) kit — it populates all six channels with 2Rx4 registered DIMMs at 1.1V for maximum supported capacity.
