32 GB DDR4 3200 ECC registered DIMM

This 32 GB DDR4 3200 module delivers error-correcting, registered memory for Supermicro UP and DP server platforms. It targets administrators who need data-integrity protection on supported SSG-520P, SSG-540P, SSG-620P and SSG-640P systems. The 2Rx8 organisation and CL22 latency suit standard server workloads.

288-pin RDIMM installation notes

The module uses the standard 288-pin DDR4 RDIMM form factor and operates at 1.20 V, so it fits any compatible slot without extra force. Registered signalling requires the platform memory controller to support registered DIMMs; unbuffered-only boards will not post. Mixing ranks or speeds can prevent the system from training at 3200 MT/s.

Sustained-load behaviour

ECC correction runs continuously during extended compute jobs, detecting and correcting single-bit errors without halting the system. Registered buffering reduces electrical load on the memory bus, helping stability when all channels are populated at 3200 MT/s. The CL22 timing remains consistent under prolonged throughput.

Questions about this item

How can I confirm the 32GB DDR4 3200 module is running at CL22 and 1.20V after installation?

Enter the server BIOS or use a tool like dmidecode to verify the detected speed shows 3200 MT/s, CAS latency reads CL22, and voltage reports 1.20V; the ECC registered status should also appear as active.

What is included with the MEM-DR432L-SL05-ER32 and what must be sourced separately?

The box contains the single 32GB 288-pin DDR4 RDIMM; any additional modules, CPU coolers, motherboards, or mounting hardware are separate purchases.

Which capacity or version of this Supermicro DDR4 3200 ECC registered memory should I choose for an SSG-640P-E1CR36H?

This specific 32GB 2Rx8 CL22 module (part M393A4K40EB3-CWE) is the listed compatible version for the SSG-640P-E1CR36H; select the same capacity and rank to match the qualified configuration.
