Gigabyte have given their Ultra Durable series a bit of a revamp for Z97 offering their boards up in Black Edition flavours. Whilst the implications of the Black Edition are fairly obviously, it is an overwhelmingly black-coloured motherboard, it also implies a new standard of durability. Gigabyte test all Black Edition series motherboards for an impressive 168 hours using server grade durability tests to ensure high reliability and stability. As if that wasn't enough Gigabyte also go to town on offering a hefty 5 year warranty and use some of the highest quality components including their ?DuraBlack? solid capacitors and their dual layer copper PCB. However, the Gigabyte Z97X-UD5H-BK isn't just about reliability, this motherboard has bucket loads of features too. Among them this motherboard has dual Gigabit LAN, one provided by Intel and the other by Killer, it has extra SATA III ports, extra USB 3.0 ports, SATA Express and M.2, support for 3-Way CrossFire, a dual UEFI BIOS, high quality ALC1150 Realtek audio, voltage measurement points, onboard buttons and a hefty 12 phase CPU VRM. On paper the Gigabyte Z97X-UD5H-BK is a fantastic high-end board so let's get on with our review and see how it shapes up in testing.
