Is M323R2GA3BB0-CQK Compatible With My System?
Before ordering, verify that your motherboard and processor support 288-pin DDR5-4800 non-ECC unbuffered UDIMM memory. Although this is a DDR5 module, it is not interchangeable with DDR5 ECC UDIMM, laptop SODIMM, registered RDIMM or load-reduced LRDIMM memory. It is also incompatible with DDR3 and DDR4 slots.
This product includes one 16GB module. Its single-rank x8 configuration describes the internal organization of that module and does not mean that multiple modules are included. When adding it to existing memory, try to match the existing module’s capacity, speed, voltage, ECC type and organization. The module may operate at a lower supported speed depending on the motherboard, processor and installed memory configuration.
