Gigabyte GA-Z77-D3H Review

A budget Z77 board that brings all the basics.

Good: Competitive performance, decent number of features, low entry level price to get Z77 chipset.
Bad: Only one PCIe slot with x16 lanes.
Price: AED 500

Starting from the top we see the CPU socket which is surrounded by the Power VRMs and MOSFETS, and on the left side a simple strip of heatsink. This layout suggests that the GA-Z77-D3H isn’t geared for heavy overclocking. However, we did manage to overclock our Core i7-2600K to 4.7GHz @ 1.45v without any trouble.

Moving to the left we see the rear I/O panel, housing the P/S2 port, 4x USB 2.0 and 4x USB 3.0 ports. Then there are the aforementioned three display ports: VGA, DVI and HDMI. Lastly we have the Atheros controlled GB LAN port and the VIA VT2021 controlled 7-channel sound ports, with S/PDIF Out.

Moving below, we see the bottom half where we see the PCIe 3.0 x16 port. Note that PCIe 3.0 only works with an Ivy Bridge processor, with Sandy Bridge processor PCIe 2.0 is in effect. The secondary PCIe slot only gets x4 lanes. This, more than anything else, shows the budget status of the GA-Z77-D3H. The large heatsink for the Z77 chipset is the same one used on the GA-Z77-UD5H.

Moving to the bottom right we see the two SATA III (6GBps) ports (in white) and four SATA II (2GBps) ports. The last of the SATA II ports becomes disabled if you use the mSATA port, so at any one time you can have a maximum of six SATA drives connected to the GA-Z77-D3H.


The BIOS is the same UEFI version seen in some of Gigabyte’s most recent motherboards, and presents most of the information nicely. Still, I prefer the ‘old school’ Advance menu where things are borken down by categories. Have look at the images below to see how easy it is to navigate and go through the GA-Z77-D3H’s UEFI BIOS.

From auditing to editing, I now test and analyze the latest gadgets and games instead of the latest financial statements. Both jobs are equally intense and rewarding. When I'm not burning up hardware in the name of science, you'll find me nuking in DOTA 2 or engineering in TF2.

    Oh and all compatible memory sticks will boot up with 1600MHz, not forced down 1333MHz like with Sandy Bridge CPUs.
