16GB DDR4 2400 ECC RDIMM

This 16GB registered DDR4 module runs at 2400MHz with CL17 latency and 1.20V operation. It uses a 1Rx4 organisation and Micron chipset for server and workstation platforms. ECC and registered buffering protect data integrity in multi-module configurations.

Verify DDR4 RDIMM slot and chipset support

Confirm the motherboard accepts DDR4 registered DIMMs and the specific Micron part numbers listed before ordering. Mixed registered and unbuffered modules will not function together. The 288-pin form factor requires a compatible DDR4 RDIMM slot.

Fits 288-pin RDIMM slots in multi-module arrays

Registered signalling reduces electrical load on the memory controller, allowing larger total capacities across populated channels. ECC corrects single-bit errors without halting the system. The 1.20V standard voltage matches DDR4 server specifications.
