AM5 Ryzen chips run best with DDR5-6000 and an AMD EXPO profile. Every pick is DDR5 with EXPO support, ordered from the lowest price.

Our comparison rests on published figures for CAS latency, rated speed and capacity; where a maker leaves out CAS latency, we say so, and no figure here comes from our own testing.

Our Picks

Lowest Price Here1 of 5

G.SKILL Flare X5 16GB (2x8GB) DDR5-5600 CL36

Flare X5 16GB offers 5600MT/s at CL36 and 1.20V with EXPO, in a low-profile design.

Best for

Keeping the cost under $500.

Skip if

Skip it if rated speed matters most to you; the Crucial Pro 6400 White offers 6400MT/s.
G.SKILL Flare X5 16GB (2x8GB) DDR5-5600 CL36

Why we like it

On CAS latency it sits mid-pack at CL36: the Viper Elite 5 RGB offers CL30, and the Delta RGB White comes in at CL38. On rated speed it trails the group at 5600MT/s, while the Crucial Pro 6400 White offers 6400MT/s. It matches the Vengeance RGB RS 16GB on capacity (16GB (2 sticks)).

No other pick in this guide offers EXPO profiles; compare the Viper Elite 5 RGB, which has EXPO and XMP profiles. It also comes with a 1.20V rating and timings of 36-36-36-89. Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed.

It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots. It undercut the Vengeance RGB RS 16GB and every other pick on price at the time of writing.
