128GB DDR5 ECC RDIMM for Supermicro SYS-222HA-TN

This 128GB DDR5 registered DIMM delivers error-correcting memory for the Supermicro SYS-222HA-TN server. It runs at 6400MHz with CL52 latency at 1.1V. The module uses a 2Rx4 organisation and major OEM DRAM chips. It is built for enterprise workloads that require data integrity and high capacity.

Server administrators needing registered ECC memory

This module suits administrators upgrading the Supermicro SYS-222HA-TN with validated ECC RDIMM memory. It is not for desktop PCs or laptops that require unbuffered non-ECC DIMMs. Builders needing lower capacities or different speeds should look at other system-specific kits. Workstations without registered memory support cannot use this module.

Tool-free DIMM slot installation

Installation follows the standard 288-pin DDR5 RDIMM procedure: power down, open the chassis, align the notch, and press until the ejectors latch. The registered buffer adds negligible physical effort. The usual mistake is mixing registered and unbuffered DIMMs in the same channel, which prevents the system from posting. Always populate slots per the motherboard manual.

Questions about this item

What motherboard slot is required for the 288-PIN DDR5 RDIMM to fit?

The module uses a 288-PIN DDR5 RDIMM form factor, so the motherboard must provide a matching 288-PIN DDR5 DIMM slot.

Can the 1.1V DDR5 6400MHz module run in a system that only supports 1.2V DDR5?

The module operates at 1.1V; if the platform only supplies 1.2V the memory may not initialise or could run out of spec.

How can I confirm the CL52 2Rx4 ECC RDIMM is recognised at 6400MHz after installation?

Check the BIOS memory information or OS tools such as dmidecode to verify the module reports 6400MHz, CL52, 2Rx4 organisation and ECC active.
