We see the VRM here is in an interesting configuration. The PWM controller, the Intersil ISL95712, is in 4+3 phase mode and features two integrated drivers for the main 4 phase rail and one on the 3 phase rail. Three Intersil ISL6625A drivers finish off the control segment of the VRM, and output to two low-side MOSFETs and one high-side MOSFET for the main CPU phases and one low-side and one high-side MOSFET for the SoC portion of the VRM.

However, GIGABYTE went and added a second inductor per each phase, so while the VRM looks like an 8+3 phase VRM; it is more like an enhanced 4+3 phase VRM. Doubling the inductor count increases current capability and decreases thermals of the VRM. MOSFETs are the ON Semiconductor NTMFS4C06N as the low-side MOSFET and NTMFS4C10N as the high-side MOSFET.

The memory VRM is a single phase VRM controlled by a Richtek RT8120D single-phase PWM controller with an integrated driver, and there are two low-side MOSFETs and one high-side MOSFET.
