First Look

The H67A is the third Gigabyte board I've reviewed but the first full-size ATX offering; the other two were both Micro ATX units. Regardless of size, all of the boards feature a uniform layout and color scheme with a blue PCB and light blue / white accessories.

At the top of the board we find a 4-pin CPU fan header, an 8-pin CPU power connector, two large passive heatsinks and four memory slots supporting up to 32GB of DDR3 1333 / 1066 / 800 MHz memory. It's worth mentioning that the heatsinks aren't terribly secure. They won't fall off or anything, but just barely bumping them on either side causes them to rock. This happens because of the mounting method of the heatinks: two push-pins, one on each end. If the two heatsinks were connected with a heatpipe, it would likely increase rigidity across both sinks.

Like some of the other P67 boards we have seen, this H67 offering from Gigabyte uses the innermost memory slot in dual channel mode which can limit the size of the CPU cooler you can use. I'll be using a Corsair water cooling kit with this build but something a bit larger like the Noctua NH-D14 Cooler might be a tough fit with large modules like the OCZ Flex EX kit.

Gigabyte is using an 8 phase power VRM design with this board which is plenty for an H67 chipset considering you can't overclock the CPU like you can on a P67 offering. We've seen up to 12 phase systems on some higher end P67 board but that would be overkill here.

Other new features include Driver MOSFET which combine the driver and MOSFETs together to reduce space and achieve higher power transfer and increased efficiency at higher switching frequencies. Gigabyte is also using Dual CPU Power Technology which they claim allows the VRM power phases to split evenly into two sets of power engines that operate in tandem. If you want to learn more about this, please visit Gigabyte's product page.

Just to the right of the memory slots is a bank of Phase LEDs. These indicate the number of power phases that the board is currently using and will increase as the CPU load increases. You must first enable Dynamic Energy Saver 2 to enable these. Below the Phase LEDs is the 24-pin ATX connector.

More just ahead.
