128GB DDR4 2933MHz ECC RDIMM

This 128GB DDR4 2933MHz ECC Registered RDIMM is built for servers and workstations that require high-capacity, error-correcting memory. It uses a Samsung chipset and carries Supermicro certification for qualified platforms. The quad-rank 2S2Rx4 organisation suits dense memory configurations.

Installation notes

The module fits a standard 288-pin DDR4 RDIMM slot and runs at the standard 1.2V voltage. Registered DIMMs must be paired only with other registered modules; mixing with unbuffered UDIMMs will prevent the system from posting. Ensure the motherboard supports 4Rx4 quad-rank modules, as some platforms limit rank count per channel.

Compatibility checks

Verify that your system’s qualified vendor list includes the Supermicro MEM-DR412L-SL01-ER29 or Samsung M393AAG40M3B-CYF part numbers. Confirm the platform accepts DDR4 2933MHz registered ECC memory at CL21 latency. Check the maximum supported capacity per slot and total memory limit before ordering.
