32GB DDR4 ECC Registered Module

This 32GB DDR4 3200MHz ECC Registered RDIMM is built for servers and workstations that require error-correcting memory. It suits administrators upgrading Supermicro platforms or similar 288-pin registered memory systems. The dual-rank 2Rx4 organisation helps populate high-capacity configurations efficiently.

Supermicro Certified 288-Pin Build

The module carries Supermicro certification under part numbers MEM-DR432L-HL01-ER32 and MEM-DR432LC-ER32. Its 288-pin RDIMM form factor fits only registered DIMM slots; it will not work in unbuffered desktop boards. Hynix chips are used throughout and every unit undergoes quality assurance testing before shipment.

Standard Voltage Thermals

Operating at 1.2V DDR4 standard voltage, the module runs within normal server thermal envelopes without additional cooling requirements. Registered buffering reduces electrical load on the memory controller, contributing to stable operation under sustained workloads. CL22 latency at 3200MHz delivers predictable bandwidth for typical enterprise applications.

Questions about this item

Does the DDR4 3200 PC4-25600 interface cap at 3200 MT/s in practice?

Yes, the module runs at DDR4 3200 (PC4-25600) with CL22 latency and 1.20 V, so the data rate tops out at 3200 MT/s on a compatible server platform.

What slot and pin count does this 288-pin RDIMM need to fit?

It requires a standard DDR4 288-pin RDIMM slot on a server motherboard that supports registered ECC memory.

How is the module installed and what step do people often miss?

Align the notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the system recognises the full 32 GB at 3200 MT/s with ECC active.
