Is M378A4G43MB1-CTD Compatible With My System?

Before ordering, verify that your motherboard and processor support a 32GB-per-slot capacity and 288-pin DDR4-2666 non-ECC unbuffered UDIMM memory. Although this is a DDR4 module, it is not interchangeable with DDR4 laptop SODIMM, ECC UDIMM, registered RDIMM or load-reduced LRDIMM memory. It is also incompatible with DDR3 and DDR5 slots.

This module uses a dual-rank 2Rx8 configuration. When adding it to existing memory, confirm that the system supports 32GB dual-rank modules and try to match the existing module’s capacity, speed, voltage and organization. The module may operate at a lower supported speed depending on the motherboard, processor and installed memory configuration.
