Supermicro-Certified 8GB DDR4 ECC RDIMM

This module is a single 8GB DDR4 3200MHz registered DIMM built for Supermicro server platforms. It operates at 1.2V with CL22 latency and uses Micron chips in a 1Rx8 configuration. The 288-pin form factor fits standard DDR4 RDIMM slots.

Certified compatibility and tested reliability

Supermicro certification means the MEM-DR480LB-ER32 part number has been validated for supported Supermicro systems. ECC registered operation detects and corrects single-bit errors to protect data integrity. All modules undergo quality assurance testing before shipment.

Suited for qualified Supermicro servers needing

Buyers must confirm their system accepts DDR4 3200MHz RDIMM modules with this exact part number. Systems requiring unbuffered UDIMM, load-reduced LRDIMM, or different voltage and rank configurations cannot use this module.

Questions about this item

Will the 8GB DDR4 3200MHz ECC RDIMM need replacement after a certain number of write cycles?

DDR4 DRAM does not wear out from write cycles like flash storage; the module is tested for reliable long-term operation and covered by a lifetime warranty.

What limits sustained throughput first — the CL22 latency or the 3200MHz bus speed?

The 3200MHz bus sets the peak bandwidth ceiling at PC4-25600, while CL22 determines per-access latency; sustained throughput is capped by the bus frequency.

How much heat does the 1.2V registered DIMM produce when running continuously in a server chassis?

At standard 1.2V DDR4 voltage the module runs cool; registered buffering adds minimal power draw, so airflow from typical server fans is sufficient.
