Patriot Viper Xtreme 5 6400 C32 Series 16GB DDR5 6400MHz CL32 Review
Shopping for the Patriot Viper Xtreme 5 6400 C32 Series in 16GB DDR5? This is Patriot's tighter-timing flagship module running at 6400MT/s CL32.
6400MT/s CL32 lands right at the top of the AM5 sweet spot, so this is a solid choice whether you're building on Ryzen or Intel and want headroom without going past the point where boards drop to a slower memory-controller ratio.
Performance
CL32 at 6400MT/s computes to a 10.0ns true latency, a genuinely tight timing for this speed bin and on par with well-regarded kits from other brands at the same rating.
Comparison to Alternatives
This is effectively a single-module counterpart to the Patriot Viper Xtreme 5 PVX532G64C32K 2x16GB kit already in our catalog, which shares the identical 6400MT/s CL32 spec — buy two of this module if a matched kit isn't available, or the kit directly if you want guaranteed-matched dies.
