DDR5 RAM is internal memory for computers, built after 2021. This internal memory is the successor to DDR4 RAM, which was released in 2014. The DDR5 RAM modules reach higher clock speeds with a lower voltage, so they work more efficiently. You're ready for the future with DDR5. The rules for choosing DDR5 RAM are the same as the last generation. Choose the speed that matches your motherboard, and always choose the right form factor. A DIMM module only fits in desktops, and a SODIMM only in laptops, for example.
