Server Memory Kit

This NEMIX RAM kit provides 256GB of DDR5 registered ECC memory across four 64GB modules. It is designed for the SuperMicro Hyper SuperServer SYS-222HA-TN and other compatible Supermicro platforms that require registered DIMMs. The modules operate at 6400MHz with a CAS latency of 52 at 1.1V.

Registered ECC Upgrade

The kit replaces non-ECC or unbuffered memory in servers that demand error correction and signal buffering for stability. The jump is worth it when workloads require maximum capacity and data integrity across all populated slots. Each module uses a 2Rx4 organisation with major OEM chips from Samsung, Micron or Hynix.

Installation Notes

Installation follows standard 288-pin DDR5 RDIMM procedures and typically takes minutes per the manufacturer. Ensure the server BIOS is current and that the platform supports registered ECC memory at this speed and capacity. Mixing with unbuffered or non-ECC modules will prevent the system from posting.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots on a SuperMicro Hyper SuperServer SYS-222HA-TN?

Yes, the kit is built for that exact server model and uses the standard 288-pin DDR5 RDIMM form factor required by its memory slots.

What is the correct order for populating the four 64GB modules during installation?

Follow the motherboard manual's channel population guide; typically you fill the same-coloured slots first to enable quad-channel operation with the 2Rx4 registered DIMMs.

How can I tell if one of the 64GB ECC RDIMMs needs replacing later?

The server's BIOS or OS logs will flag correctable ECC errors; a rising count on a specific module indicates that DIMM should be swapped out.
