16GB DDR4 3200 ECC RDIMM for Supermicro EPYC

This registered DIMM provides 16GB of DDR4 3200 memory with ECC error correction. It is built for the Supermicro H12DST-B motherboard and AMD EPYC server platforms. The module uses a 2Rx8 organisation and operates at 1.2V.

Registered DDR4 3200 speed and CL22 latency

The PC4-25600 standard sets the maximum data rate at 3200 MT/s with a CAS latency of 22 cycles. Registered buffering adds one clock cycle of address delay, which limits the highest frequencies reachable compared to unbuffered modules. ECC parity bits reduce usable bandwidth slightly versus non-ECC equivalents.

Simple DIMM slot installation with population rules

The 288-pin RDIMM inserts vertically into the motherboard DDR4 slots and locks with the side latches. Supermicro H12DST-B requires specific slot population order per CPU socket; installing modules in the wrong sequence will prevent the system from posting. No heat spreader is fitted, so airflow across the PCB must be maintained by the chassis fans.

Questions sur cet article

Is this 16 GB module the right capacity for my Supermicro H12DST-B, or should I choose a different size?

This module provides 16 GB in a single 2Rx8 DDR4 RDIMM. The H12DST-B supports multiple capacities per slot; match the total memory you need and keep rank counts consistent across channels.

What does the 3200 speed rating actually deliver once installed in an EPYC system?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2 V. Real-world throughput depends on the CPU memory controller, channel population and BIOS settings.

How does the 288-pin RDIMM interface and ECC registration affect compatibility and limits?

The 288-pin DDR4 RDIMM form factor with registered ECC is required by the H12DST-B. Registered buffering allows higher capacities per channel, while ECC corrects single-bit errors for server reliability.
