Is M378A2G43AB3-CWE Compatible With My System?
Before ordering, verify that the motherboard and processor support 288-pin DDR4 non-ECC unbuffered UDIMM memory. The system must also support 16GB module capacities and a single-rank 1Rx8 organization.
This module is not interchangeable with DDR3 or DDR5 memory. It also cannot replace a laptop SODIMM, ECC UDIMM, registered RDIMM or load-reduced LRDIMM. When adding memory to an existing system, compare the complete part number, capacity, speed, voltage and rank organization with the installed modules.
The module may operate below 3200 MT/s when limited by the processor, motherboard, firmware or installed-memory configuration.
