The X399 Aorus Xtreme shows us what it's got under the hood when we remove the heat sinks and shields.
The VRM for the core VRM is a 10 phase VRM which is five PWM phases doubled to 10 using doublers. The IR35201 is used in 5 phase mode, and controls ten IR3578. The IR3578 are 50A power stages, but they are much more easily cooled due to their metal tops. However, they are also significantly more pricey than their IR3556 counterparts.
We find five IR3599 doublers on the rear of the motherboard. The SoC VRm is made up of three IR3578 and is controlled by an IR3570.
Each of the two memory VRMs offer two phases for the main DDR made up or IR3553, and then another IR3553 for the VPP. The memory VRMs are controlled by an IR3570 in 2+1 phase mode. That's overkill.
