Server ECC RDIMM for Supermicro EPYC

This 16 GB DDR4 3200 registered module is built for Supermicro H12SSW-iN motherboards running AMD EPYC processors. It delivers error-correcting code protection and registered signalling for stable operation in mission-critical server and workstation environments.

Low-voltage operation at 1.2 V

Running at 1.20 V with CL22 latency, the dual-rank 2Rx8 design draws minimal power while maintaining data integrity under sustained loads. The absence of a heat spreader keeps the profile slim for dense chassis airflow without adding acoustic noise.

Replaces non-ECC or slower DDR4 DIMMs

Upgrading from standard unbuffered memory or lower-speed registered kits adds hardware error correction and 3200 MT/s throughput for virtualization and database workloads. The jump is worthwhile when uptime and data accuracy outweigh raw capacity expansion.

Questions about this item

How is this 288-pin DDR4 RDIMM installed, and which step do people often get wrong?

Align the module notch with the slot key, press straight down until both retention clips click, and verify the board detects the full 16 GB at 3200 MT/s; the common mistake is stopping before the clips lock, leaving the module partially seated.

What maintenance or replacement will this ECC registered module need later?

No routine maintenance is required; if a correctable error count rises or the module fails stress testing, replace the single 16 GB stick — there are no user-serviceable parts on the board.

What limit appears first under sustained load on this CL22 1.2 V kit?

The CAS latency of 22 cycles at 3200 MT/s sets the timing floor; under continuous throughput the memory controller will hit that latency bound before voltage or thermal limits become a factor.
