Server-Specific Memory Kit

This 128GB kit uses four 32GB DDR5 RDIMM modules built for the Supermicro SYS-222HA-TN platform. It targets administrators who need registered ECC memory to maintain data integrity in multi-socket server workloads. The modules run at 6400MHz with a CL52 latency profile.

Registered ECC Integration

Registered buffering reduces electrical load on the memory controller, allowing all four slots to be populated without signal degradation. ECC circuitry corrects single-bit errors transparently, protecting critical applications from silent data corruption. The 1.10V operating voltage matches the platform's DDR5 power specification.

Four-Module Population

The kit fills a complete memory channel set with matched 2Rx8 modules, enabling the board's maximum supported bandwidth for this configuration. No heat spreaders are included, so airflow across the bare DRAM must be provided by the server chassis fans. The 288-pin form factor ensures mechanical compatibility with the target system's DDR5 slots.

Questions about this item

Does the CL52 latency limit throughput during sustained server workloads?

CL52 is the rated CAS latency at 6400MHz; sustained throughput depends on the Supermicro SYS-222HA-TN memory controller and BIOS tuning.

How much heat does the 1.1V 2Rx8 kit generate when running all day in the SYS-222HA-TN?

The modules run at 1.10V without heat spreaders; actual thermals depend on chassis airflow and DIMM density in the Supermicro server.

Must the Supermicro SYS-222HA-TN already have a DDR5 RDIMM slot layout that accepts 288-pin 2Rx8 modules?

Yes, the kit is built for the SYS-222HA-TN and requires its native 288-pin DDR5 RDIMM slots supporting registered ECC memory.
