GIGABYTE’s GA-Z87X-UD5H offers an  ensemble of passive cooling and enhanced  power capabilities through its Ultra Durable  5 Plus technology. The resulting reliability  and stability made the GA-Z87X-UD5H an  ideal fit for our overclocking needs. Support  for up to 32GB of memory (at frequencies  up to DDR3-3000) and two GPUs in SLI or  CrossFire didn’t hurt, either.

GIGABYTE installed large heatsinks  that run along the PWM and PCH areas  to help keep the motherboard within  optimal thermals. The Ultra Durable 5 Plus  technology also includes Black Solid Caps  that are rated for 10,000 hours of operation at  105 degrees Celsius. The CPU socket receives  digitally-controlled power from International  Rectifier’s PowIRstage ICs. Even the BIOS  is protected with GIGABYTE’s DualBIOS  design, which provides both a main and  backup BIOS.
When it comes to overclocking our Intel  Core i7-4770K, we had plenty of available  information and control from the GAZ87X-UD5H. Voltage read points along  the top right of the motherboard let us use  a multimeter to get real-time readings for  core voltage, DIMM voltage, and more. For  troubleshooting, GIGABYTE provides a  debug display and onboard power, reset, and  clear CMOS buttons. The GA-Z87X-UD5H  also comes with GIGABYTE’s EasyTune  software, so we could adjust frequency and  voltage settings in Windows.
A good gaming rig requires a mobo with  support for multiple GPU configurations,  and the GA-Z87X-UD5H meets our needs  in this regard, as well. It provides full support  for two-way SLI and CrossFire, and includes  a SATA power connector along the right side of the motherboard to help deliver additional  power stability for multi-GPU setups. There’s  space for other add-on cards too, as you’ll find  another PCI-E x16 slot (doesn’t support triple  SLI or CrossFire), three PCI-E 2.0 x1 slots,  and a legacy PCI slot.
For internal storage, there are 10 6Gbps  SATA ports; the top six are the stock Z87  chipset ports and support RAID 0, 1, 5, and  10 configs. The bottom four are powered by  a Marvell 88SE9230 chip and support RAID  0, 1, and 10 configurations. The SE9230  controller also supports Marvell’s HyperDuo  Technology, which allows an SSD to act as a data cache for a connected HDD, giving you  an optimal blend of capacity and speed. There  are six USB 3.0 ports on the back panel and  four more are available via internal headers.
GIGABYTE made performance a priority  with the GA-Z87X-UD5H, but still manages  to provide top-shelf reliability and stability.
In short, we expect this motherboard to be a  mainstay in the system for years to come.
