GIGABYTE Z170X-UD3 Ultra Motherboard Review

Circuit Analysis




The Z170X-UD3 Ultra has a nice looking PCB.





The VRM on the Z170X-UD3 Ultra is very simple. Four phases are dedicated to the CPU Core and three phases are dedicated to the iGPU. The Intersil ISL95856 4+2 phase PWM controller. It has two separate PWM rails, the rail with four phases has two integrated drivers and the rail with three phases has a single integrated driver.


GIGABYTE has added two ISL6625 drivers for the four phase rail and two for the three phase rail so that all PWM phases on both rails can be utilized. Each phase uses a Vishay SiRA12 and SiRA18 for the low-side and high-side MOSFETs. The VRM on this motherboard should be enough to get things done, but it probably isn't the best for crazy overclocks.




The memory VRM uses a single phase PWM with an integrated driver, the Richtek RT8120D, and three Vishay SiRA12 (two low and one high). Minor rails like VCCIO and VCCSA are powered by linear regulators located south of the CPU socket area.
