DDR4 and DDR5 modules cannot stand in for one another — even the notch in the contacts differs — so the first thing to look at is what the board needs, and for laptops the shorter SO-DIMM form as well. Next comes the choice of frequency (3200 MT/s for DDR4, 5600–6400 MT/s for DDR5) and CL latency. A kit of two modules usually works faster than a single one of the same capacity, because dual-channel mode kicks in. Kingston FURY Beast, Goodram IRDM and HyperX turn up most often.
