G.Skill Trident Z5 F5-8400J4052G24G 24GB DDR5-8400 CL40 (No RGB, Silver Top) Review
This single 24GB G.Skill Trident Z5 module runs an extreme DDR5-8400 CL40 without RGB lighting
one of the fastest-rated non-RGB modules in this catalog, aimed at Intel high-end builds that want bandwidth without paying for a light bar.
Performance
CL40 at 8400MT/s computes to 9.5ns true latency, beating AM5's 6000MT/s sweet spot on paper while running well past what most AM5 boards can hold at a 1:1 ratio; this is squarely an Intel-tier speed.
Compatibility
8400MT/s demands a proven high-end Intel board and CPU memory controller; check the board's QVL closely before buying, and expect this to fall back to a slower ratio on any AM5 system.
