The VRM is in a 14+2 phase configuration, and it's a 7 phase VRM doubled to 14 phases through doubling components. ASUS says that this method offers quicker response to large transient loads, and that's why they opted to not use doublers. The PWM controller is most likely an IR35201 rebranded to an ASP for ASUS. The power stages are rated 60A and they are the IR3555. The two SoC VRM phases utilize the same 60A PowIRstages. The VRM is overkill, which is a nice thing.

The memory VRM uses an ASP1103 PWM controller with two phases made up of On Semiconductor small form factor PowerPAKs. The memory VRM is more than enough to satisfy memory overclocking requirements.
