Server-grade DDR4 module

This 32 GB DDR4 3200 MHz RDIMM uses Micron chips and runs at 1.20 V with CL22 latency. It is a registered ECC module built for Supermicro platforms and carries the MEM-DR432LC-ER32 part number.

Registered ECC integration

The 288-pin RDIMM format requires a motherboard that supports registered ECC memory and DDR4 3200 speeds. The dual-rank 2Rx4 organisation increases density per slot so fewer modules are needed to reach large capacities.

Suited for Supermicro servers

Ideal for administrators expanding memory in qualified Supermicro systems that accept registered ECC DIMMs. Not suitable for desktop boards that only accept unbuffered non-ECC memory or for builds needing speeds beyond DDR4 3200.

Questions about this item

Will the CL22 latency hold up under sustained 3200 MHz throughput?

The module is rated CL22 at DDR4 3200 and uses Micron chips tested to Supermicro certification standards.

How much heat and power does a 32 GB registered DIMM add during all-day operation?

It runs at the standard DDR4 voltage of 1.20 V, so power draw and thermal output stay within normal registered DIMM limits.

What motherboard slot and CPU memory controller are required for this 2Rx4 ECC RDIMM?

It needs a 288-pin DDR4 RDIMM slot and a CPU or chipset that supports registered ECC memory.
