Gigabyte Z87 Haswell Motherboard Round-Up

We’ve already seen what ASUS has to offer in the way of its Republic of Gamers Z87-based motherboards, and now we’re having a look at Gigabyte’s take on Intel’s latest chipset that supports 4th generation Core Series Haswell processors. Gigabyte sent us a sampling of three motherboards that offers a broad overview of the options in the company’s line: the solid and affordable Z87X-UD4H, their G1.Sniper5 gaming beast, and the Z87X-OC Force flagship overclocking board.

Gigabyte's Primary Z87 Features

The heart of Gigabyte’s Z87 platform is its Ultra Durable 5 Plus, which includes its heatsink design, CPU power design, and DualBIOS feature. The heatsinks on these Z87 boards vary somewhat from mainboard to mainboard, but as a line they offer passive, active, and water cooling setups around the CPU socket and chipset. For example, the Z87-UD4H has a passive heatsink, but both the G1.Sniper5 and Z87X-OC Force have fans and posts that are geared for liquid coolers.

The motherboards also feature an all-IR (International Rectifier) digital CPU power design, including PWM controllers and PowlRstage ICs that were built to work together to offer precision tuning and optimal cooling. 

Gigabyte’s DualBIOS design offers a main BIOS and a backup BIOS--literally, two separate chips--so that if something goes terribly wrong with the main BIOS, the backup is there to ensure that you can recover everything with no trouble.

The company is particularly proud of the quality of their board components. For example, these Z87 boards have black solid caps that are rated for 10,000 hours at 105 degrees C. The USB and LAN ports each have a dedicated protection filter for preventing damaging electrostatic discharges, and Gigabyte also used one fuse for every USB port instead of one fuse for multiple ports; the idea is that if a fuse blows, you only lose a single USB port instead of a whole bank. This is actually a rather attractive feature; USB ports are notorious for crapping out at times, so allowing one port to cough up a hairball while the rest remain healthy is a welcome build feature.

Further to the point of craftsmanship, the motherboards’ CPU sockets are gold-plated, which prevents corrosion and thus helps ensure a longer lifespan for the board itself; on some models, such as the Z87X-OC Force, the interior of the PCI and DIMM slots have gold, too. Finally, the PCBs have two layers of copper in the circuit board sandwich, which Gigabyte says enables larger power loads to flow from component to component and also wicks away heat better. 

Gigabyte has, as is typical, taken great care in the construction of these motherboards, employing small enhancements that add up. For example, the Z87 boards have a high-capacity front headphone amplifier designed to drive 600Ω loads, an Intel Gigabit LAN, and plenty of fan speed support. Each board has plenty of fan connectors (no fewer than 6), and Gigabyte put in OPT fan support, so users can implement a water pump that will run continuously at full speed (or just support a dual-fan cooler).

Gigabyte has also employed cFosSpeed traffic shaping and prioritization technology for better network performance and fast charging of mobile devices connected to USB (whether the computer is on or not) with On/Off Charge 2.
