A-Tech Supermicro Certified 32GB DDR3 1866MHz LRDIMM 4Rx4 ECC server RAM

Certified Supermicro LRDIMM for server workloads

This 32GB DDR3 1866MHz module carries the Supermicro Certified MEM-DR332L-SL02-LR18 designation and uses Samsung M386B4G70DM0-CMA chips. It is built for servers that require ECC Load Reduced memory in a 240-pin form factor. The quad-rank 4Rx4 organisation suits platforms qualified for this specific part number. Buyers who need a different rank structure or a non-LRDIMM module cannot use this unit.

Sustained operation at 1.50V with CL13 latency

The module runs at standard DDR3 voltage and maintains rated timings under continuous load thanks to the Load Reduced architecture that lowers electrical stress on the memory controller. ECC correction operates continuously to protect data integrity during long compute runs. Systems not validated for 4Rx4 LRDIMM populations will not support this configuration.

The stick uses Samsung silicon and follows the 240-pin LRDIMM pinout, so it fits only slots wired for that interface. Supermicro certification confirms the module passes the vendor’s qualification suite for compatible platforms. Builders whose motherboards lack explicit support for this part number must select a different module.
