Memory is simple to buy once you know three things: the generation your motherboard uses, how much you need, and the speed that suits your platform.
DDR4 and DDR5 are not interchangeable. AM5 and LGA1851 boards take DDR5; LGA1700 boards take one or the other, so check the board first.
Check RAM compatibility in the PC Builder →16 GB is the minimum for gaming today; 32 GB is the comfortable choice for gaming plus streaming or multitasking; 64 GB is for heavy editing or virtual machines.
Two sticks (for example 2×16 GB) run in dual channel and are noticeably faster than a single stick of the same total size.
DDR5-6000 is the sweet spot for AM5. Turn on EXPO (AMD) or XMP (Intel) in the BIOS, otherwise the memory runs at its slower base speed.
