Gigabyte has once again designed a great board packed with tons of features and hardware. This includes dual M.2 32Gbps slots, dual UEFI BIOS, dual Intel gigabit NICs, three SATA Express connectors, eight SATA 6Gbps ports, six from the Intel chipset plus two additional, Realtek ALC1150 audio chipset with the Gigabyte isolation LED trace path, which now includes the ability to switch from solid on to pulse to flash with activity, two USB 3.1 and three USB 3.0 ports built in, with additional headers for USB 3.0/2.0 slots, five 4-pin fan headers, onboard Power, Reset, clear CMOS and OC buttons. The PCB utilizes Gigabyte's 2X copper design and they've added additional shielding on the three 16X PCI-E slots to support heavy graphics cards.
I had zero issues with the Kingston HyperX Fury DDR4-2666 memory running at the rated XMP profile right out of the box, although some users have complained about memory compatibility. Gigabyte has released several beta BIOS for this board to address this issue so if you're experiencing problems, try flashing from the factory F3 or F4 to the latest beta BIOS.
I did run into an issue booting from a SATA drive when using RAID configuration mode, however again this was with the as-shipped F3 BIOS, and once flashing to the latest beta the issue was corrected. The only other complaint I've seen has to do with 4K resolution support at only 30Hz instead of 60Hz, due to either the onboard HDMI port being version 1.4 or the DisplayPort only supporting 1.1 standard. As I don't have a 4K capable display, nor use integrated graphics, this was a non-issue for me.
When it comes to price the Gigabyte Z170X-UD5 weighs in at a somewhat hefty $180-$190 range, which is a bit surprising given some of Gigabyte's other offerings such as the Z170X-UD3 or Z170X Gaming 3, which seem to include many of the same features with a significantly lower cost. The main difference seems to be in the power components used between the boards, and it appears only the Gaming G1 and SOC Force may exceed the UD5 power handling capability. And all of Gigabyte's Z170 chipset boards carry the Ultra Durable 3 Year Warranty.
If you're looking for a solid Z170 chipset motherboard with lots of features and great support, Gigabyte has nearly 20 different boards to offer.
OCIA.net awards the Gigabyte Z170X-UD5 our Gold Seal of Approval.
