I'd love have someone show me a 17-17-17 4000mhz in a 2 stick config on their GB Z390 board running stable.
Yep, that's the reason I switched to 4 sticks of B-die. My friend's ASRock Taichi Z390 fires right up in XMP at 4000 with 2 sticks with a G.skill 4000 CL18 2 stick kit, at 1.35v. I had the same kit and it was a nightmare even getting it to boot at all, at 4000. This was on a Z390 Pro board, the Master might be a little better in this regard.
