4GB DDR4 2133 ECC RDIMM Server Module

This 4GB registered DIMM runs at DDR4 2133 (PC4-17000) with CL15 latency and 1.20V operation. It uses 1Rx8 organisation and major-brand chips to deliver error-correcting memory for server and workstation workloads. The 288-pin form factor fits standard DDR4 RDIMM slots.

Check DDR4 RDIMM slot availability

Verify that your system accepts DDR4 registered ECC modules before ordering. The platform must support 1Rx8 registered DIMMs at the 2133 MT/s data rate. Mixing registered and unbuffered memory is not supported on the same channel.

Replaces Dell 370-ABUI, 370-ABUM, 370-ACIK.

This module directly substitutes the listed Dell part numbers in compatible servers and workstations. The upgrade is worthwhile when ECC capacity is exhausted or when replacing failed sticks with validated equivalents. It does not address needs for higher-density or faster-speed modules.
