Server memory kit for Supermicro SYS-122HA-TN-LCC

This 256 GB kit contains four 64 GB DDR5 ECC RDIMM modules rated at 6400 MHz with CL52 latency. Registered buffering and on-die ECC protect data integrity in the Supermicro Hyper SuperServer SYS-122HA-TN-LCC. The modules run at 1.1 V and use a 288-pin form factor with 2Rx4 organisation.

Suited for administrators expanding that specific

Buyers who need memory for a different platform, a non-ECC desktop board, or a lower-capacity upgrade should look elsewhere. The kit is built for registered DDR5 slots and will not function in unbuffered consumer sockets or in systems that do not support 64 GB RDIMMs.

Four matched modules simplify installation

The package delivers a complete 256 GB population in one kit, so all slots receive identical timings and voltage. No extra cables, software licences or heat spreaders are included; the modules are ready to install once the server firmware supports the stated speed and capacity.

Questions about this item

Does the Supermicro SYS-122HA-TN-LCC require DDR5 ECC RDIMM modules to accept this 256GB kit?

Yes, the SYS-122HA-TN-LCC is a DDR5 platform that only accepts 288-pin ECC RDIMM modules, which this kit provides.

Can I mix these 6400MHz CL52 2Rx4 modules with slower DDR5 RDIMMs already installed in the same server?

The server will run all channels at the speed and timing of the slowest installed module, so mixing is possible but reduces total bandwidth.

How do I verify the full 256GB is recognised and ECC is active after installing the four modules?

Check the BIOS memory summary for 256GB total and ECC enabled, then confirm in the OS with dmidecode or lsmem showing 4 x 64GB DDR5 6400 RDIMM with ECC.
