  • 1V operation reduces power draw in compatible Supermicro systems
  • 288-pin RDIMM form factor installs directly into SYS-222HA-TN servers

Server-grade DDR5 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 6400 CL52 ECC registered DIMMs built for the Supermicro SYS-222HA-TN. Each module runs at 1.1V with a 2Rx8 organisation and 288-pin layout. It targets administrators who need registered error-correcting memory for that specific platform.

Replaces slower or smaller DDR5 RDIMMs

The jump is worthwhile when the workload demands both higher bandwidth and the data-integrity protection of ECC registered modules. Systems already populated with lower-capacity or lower-speed DDR5 RDIMMs gain capacity headroom and throughput without changing memory topology.

Limited to platforms that accept DDR5 288-pin RDIMMs

The memory controller must support 6400 MT/s operation at CL52 timings and 1.1V registered signalling. Boards restricted to UDIMM, lower DDR5 speeds or different pin counts cannot use this kit. Always verify the system qualification list before purchase.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Supermicro SYS-222HA-TN memory slots?

Yes, the kit uses the standard 288-pin DDR5 RDIMM form factor that matches the SYS-222HA-TN DIMM sockets.

What is the correct sequence for seating both 32 GB modules in the server?

Power down, open the chassis, align each module notch with the slot key, press firmly until both side latches click, then close the chassis before powering on.

When should the ECC RDIMM kit be replaced if correctable error counts start rising?

Replace the kit when the platform logs show a sustained increase in correctable ECC errors, indicating chip degradation.
