GIGABYTE released a major revision of Aorus Z370 Ultra Gaming motherboard. This isn't just marked "Rev 2.0" in some obscure corner of the PCB, but is part of the model name - Z370 Ultra Gaming 2.0. It replaces the 7-phase CPU VRM of the original with a new 11-phase setup that uses stronger ferrite-core chokes that don't whine when stressed. The company is also including one M.2 SSD heatsink for the upper M.2-22110 slot, which the original lacks.Besides these, the Aorus Z370 Ultra Gaming 2.0 is identical to the original, including its RGB LED diffusers, multiple RGB headers governed by GIGABYTE RGB Fusion software, two reinforced PCI-Express 3.0 x16 slots (x8/x8 when both are populated) with NVIDIA SLI support, one gigabit Ethernet interface driven by an Intel i219-V controller, and a premium onboard audio solution with a headphones amplifier and 120 dBA SNR CODEC (Realtek ALC1220); and a price ranging between $150-$170.
