GIGABYTE X150M-PRO ECC Xeon Motherboard Review

Circuit Analysis




The heat sinks don't cover up much, so the board looks the same without heat sinks.





While most Z170 motherboards have two larger voltage regulators for the core and iGPU sections, many Skylake Xeons don't have integrated GPUs, and in this case integrated graphics aren't supported and so the VRM for the integrated graphics isn't present. Instead, we have a three-phase VRM for the CPU's core voltage.




The Intersil ISL95858 is a 3+2 multiphase PWM regulator, but in this case, only the first three phases are being used. The first two of three phases have integrated drivers, while the last phase uses an external driver, the Intersil ISL6625A. Each phase is made up of an NTMFS4C06N for the low-side MOSFET and an NTMFS4C10N for the high-side MOSFET.




The memory VRM pictured above uses a Richtek RT8237C as the PWM controller with integrated driver and two NTMFS4C10N for the low-side and a single for the high-side.
