The Gigabyte Z77X-UD5H-WB comes on a black PCB with the blue coolers and black expansion slots. The layout itself has been well thought and there is for example plenty of space around the CPU socket to install even todays largest CPU coolers. There also are angled SATA connectors which let you install oversized graphics cards easily.

Gigabyte equipped the Gigabyte Z77X-UD5H-WB WiFi with a 15 (6x2 + 2 + 1) phase power design for the processor. In fact there are six times two phases for vcore, two phases for IGP (Integrated Graphic Processor) and finally one phase for IMC (Integrated Memory Controller)/VTT. As for the other components, the memory benefits power from two phases, the PCH - also known as southbridge - is powered by one single phase.

Totally you'll find four DIMM-slots on the Gigabyte Z77X-UD5H-WB WiFi. Officially supported are the following clock speeds: 2400 / 1600 / 1333 / 1066 MHz. There is also enough space between the DIMM-slots and the CPU socket which means that you won't encounter compatibility issues with tower coolers even when you choose to install RAM with big heatspreaders. Meanwhile with a double tower cooler you may find some incompatibility issues with high end memory that ships with huge heatspreaders.

On the Gigabyte Z77X-UD5H-WB WiFi southbridge as well as VRM are being cooled via passive cooling blocks that are connected to eachother via heatpipes. The coolers for the VRM are well positioned and also around the DIMM slots there is plenty of space. Therefore no cooler will collide with one of the onboard components.
