System-Specific Upgrade

This NEMIX RAM kit delivers 128GB of DDR5 ECC registered memory in a matched pair of 64GB modules. It is built for the Supermicro Hyper SuperServer SYS-222HA-TN and targets administrators expanding capacity on that platform. The modules operate at 6400MHz with a CAS latency of 52 and run at 1.1V. Registered signalling and on-die ECC provide the data integrity required in server workloads.

Suitability Guidance

This kit suits IT teams adding registered ECC memory to the named Supermicro system. It is not for desktop PCs, workstations or laptops that accept only unbuffered UDIMM modules. Buyers who need non-ECC memory, lower voltages or different form factors should look elsewhere. The 2Rx4 organisation and 288-pin RDIMM interface limit use to compatible registered DDR5 channels.

Deciding Specification

The registered ECC RDIMM interface combined with DDR5 6400MHz speed determines whether this kit fits the target server. Only systems qualified for 288-pin DDR5 RDIMM modules at PC5-51200 with CL52 timing and 1.1V operation can use this memory. Verify the platform memory-qualified vendor list before purchase.

Questions about this item

How much power does the 1.1V DDR5 6400MHz kit draw when the SYS-222HA-TN runs continuously?

Each module operates at 1.10V, the standard DDR5 voltage, so power scales with the 128GB capacity and 6400MHz data rate under sustained server workloads.

What motherboard slot and firmware support are required to run this 288-pin ECC RDIMM kit?

The SYS-222HA-TN must provide DDR5 288-pin RDIMM slots with ECC and registered DIMM support in the BIOS for the 2Rx4 modules to initialise correctly.

Will the 2Rx4 organisation of these 64GB modules work with older single-rank RDIMMs already populating other channels?

Mixed-rank populations are governed by the Supermicro memory reference guide; the 2Rx4 modules can share a channel only with matching rank and speed configurations.
