32GB DDR4 3200 ECC Registered module

This 32GB DDR4 3200 module provides error-correcting registered memory for Supermicro UP and DP server platforms. It operates at 1.20V with a CAS latency of CL22 and uses a 2Rx8 rank configuration. The 288-pin RDIMM form factor fits compatible Supermicro SSG-520P, SSG-540P, SSG-620P and SSG-640P systems.

Build integration with Supermicro servers

The registered design places a buffer between the memory controller and the DRAM chips, reducing electrical load on the CPU memory interface. ECC functionality detects and corrects single-bit errors to maintain data integrity in continuous operation. Compatibility is limited to the listed Supermicro UP and DP server models; other platforms are not supported by this module.

Sustained operation in server workloads

Registered buffering and ECC correction work continuously during extended compute tasks, preventing error accumulation that can crash long-running jobs. The 1.20V operating voltage and DDR4 3200 speed rating are maintained under constant load within the validated Supermicro server configurations. Modules not installed in the listed SSG series systems have no verified behaviour.

Questions about this item

Does the CL22 latency limit throughput when the server runs sustained workloads?

The module operates at DDR4 3200 with CL22 latency, which is the rated timing for continuous operation at 1.20V.

How much heat and power does a 32 GB registered DIMM add when the system runs all day?

Each 2Rx8 RDIMM draws 1.20V at DDR4 3200; registered buffering and ECC add minimal overhead versus unbuffered modules.

Which Supermicro server models must I already own for this MEM-DR432L-CL07-ER32 kit to work?

Compatible platforms include UP servers SSG-520P-ACTR12H, SSG-520P-ACTR12L, SSG-540P-E1CTR36H, SSG-540P-E1CTR36L and DP servers SSG-620P-ACR12H, SSG-620P-ACR12L, SSG-640P-E1CR24H, SSG-640P-E1CR24L, SSG-640P-E1CR36H, SSG-640P-E1CR36L.
