System-Specific DDR5 Server Memory Kit

This NEMIX RAM kit delivers 256GB across eight 32GB DDR5 ECC RDIMM modules rated at 6400MHz with CL52 latency. Registered buffering and on-die ECC protect data integrity in Supermicro Hyper SuperServer SYS-222HA-TN systems. The 1.1V operating voltage matches the platform's standard DDR5 power envelope. Modules use major OEM Samsung, Micron or Hynix DRAM components.

Compatibility Check Before Ordering

Verify that your Supermicro SYS-222HA-TN motherboard has eight available 288-pin DDR5 RDIMM slots and supports 2Rx8 registered modules at PC5-51200 speed. Confirm the BIOS revision accepts 256GB total capacity and that the memory population rules for this server allow all eight slots to be filled simultaneously. Ensure the chassis airflow can cool bare modules without heat spreaders.

What the Kit Configuration Changes

Supplying eight matched 32GB sticks in a single kit removes the risk of mixing revision codes or rank configurations that can prevent multi-channel operation. The factory-tested set enables full eight-channel bandwidth on supported Supermicro platforms without manual bin sorting. Registered buffering reduces electrical load on the memory controller, allowing the full 256GB population at rated speed.

Questions about this item

Does the 256GB kit arrive as eight 32GB modules or do I need to buy extra sticks?

The package contains eight 32GB DDR5 RDIMMs giving 256GB total; no additional modules are required.

Should I choose the CL52 6400MHz version or a different latency for the Supermicro SYS-222HA-TN?

CL52 at 6400MHz is the specified speed and latency for this kit and matches the Supermicro SYS-222HA-TN memory profile.

What does the 6400MHz PC5-51200 rating mean for actual throughput in the server?

It provides a peak transfer rate of 51200 MB/s per module when the motherboard runs the memory at 6400MHz.
