The ASUS Prime Z270-A has 4 DDR4 288-pin DIMM slots and a 64GB maximum. It accepts non-ECC, unbuffered desktop DDR4 from 2133 MT/s through 3866 MT/s overclocked, with XMP support; the processor and BIOS decide whether a fast profile is stable. The smart upgrade is a matched 2x16GB kit for 32GB, installed in the recommended paired slots. Every pick below is desktop UDIMM RAM—none is laptop SO-DIMM memory—and the mix includes easy 3200 MT/s kits plus faster options for a K-series CPU and a tested XMP setup.

Buying tips
- Install a two-DIMM kit in A2 and B2, then enable XMP in UEFI before judging its speed.
- For 4 DIMMs, use one matched 4-stick kit or the ASUS memory QVL; do not combine two retail kits.
- A 6th-generation CPU can have less memory-clock headroom than a 7th-generation Kaby Lake CPU.
