32 GB DDR4-3200 ECC RDIMM for Supermicro servers

This 32 GB registered DIMM runs at DDR4 3200 with CL22 latency and 1.20 V. It uses a 2Rx4 Samsung chipset and fits 288-pin server slots. The module is certified for Supermicro systems that require ECC registered memory.

Supermicro certification and Samsung components

Supermicro validation confirms the MEM-DR432LC-ER32 part number works in qualified platforms without additional qualification. The Samsung M393A4K40DB3-CWE chips provide the stated density and speed. A-Tech testing adds a further reliability check before shipment.

Registered ECC architecture decides fit

The RDIMM register and ECC circuitry mean this module only works in motherboards designed for registered ECC DDR4. Unbuffered or non-ECC boards will not accept it. Verify your platform supports registered ECC before ordering.

Questions about this item

Will the Samsung chips in this MEM-DR432LC-ER32 module need replacement under normal server workloads?

The module uses Samsung DDR4 chips rated for standard 1.20V operation and is validated through Supermicro certification testing; no periodic chip replacement is required.

What limits sustained throughput on this 32GB DDR4 3200 RDIMM during continuous operation?

The CL22 latency at 3200MHz and the registered buffer each add fixed cycles, so the memory controller's command scheduling becomes the first bottleneck under heavy sustained load.

How much heat and power does this 2Rx4 ECC RDIMM produce when running all day at 3200MHz?

At the specified 1.20V the module draws standard DDR4 power for a 32GB dual-rank stick; the registered design adds minimal overhead, and passive airflow in a server chassis is sufficient for cooling.
