Server-grade DDR5 for Supermicro SYS-222HA-TN

This 32 GB registered DIMM delivers error-correcting DDR5 memory at 6400 MHz with CL52 latency. It is built for the Supermicro Hyper SuperServer SYS-222HA-TN and operates at 1.1 V using 2Rx8 organisation. The module targets administrators who need reliable capacity expansion in a validated server platform.

Single-module kit with major-OEM DRAM

The package contains one 32 GB stick populated with Samsung, Micron or Hynix components. No heat spreader is included, so airflow in the chassis must handle thermal management. ECC and registered signalling protect data integrity in multi-DIMM configurations without adding extra software or cables.

Tool-less DIMM installation in minutes

The 288-pin RDIMM seats in the standard DDR5 server slots; the supplier notes that upgrades typically take a couple of minutes. Builders must still consult the system manual for slot population rules and maximum supported capacity. Systems requiring unbuffered UDIMMs or non-ECC memory cannot use this module.

Questions about this item

Will the ECC RDIMM modules need any firmware updates or scheduled replacement after installation?

No firmware updates are required for the DDR5 ECC RDIMM; the module is a solid-state component with no moving parts and no scheduled replacement interval.

What thermal or signal-integrity limit appears first when the 6400 MHz CL52 kit runs continuously at full load?

The registered DDR5 design operates at 1.1 V with CL52 latency, so the memory controller's timing margin and the module's thermal envelope are the first constraints under sustained throughput.

How much heat and power does the 32 GB 2Rx8 stick produce when the server runs all day?

At 1.1 V the module draws low power for DDR5 RDIMM class, and with no heat spreader it relies on chassis airflow to stay within normal operating temperature.
