The A75M-D2H is a micro-ATX form factor, measuring 24.5cm x 22.5cm. It has support for the entire A-series APU lineup (A8/A6/A4/E2) and is part of the Ultra Durable series.
From left to right, we see the VIA VT6308P 1394 controller chip sitting above the HD audio connector. Next we have the trusted platform header, the COM header for serial port, and a single 20-pin USB 3.0 header. Above these headers, we see the dual-PCIE x16 slots (the top slot runs at x8 and the bottom at x4 mode). In between the PCIE slots are a PCIE x1, and a legacy PCI slot. In the adjacent photo, we see the new ceramic-coated heatsinks that Gigabyte has designed for the newest generations of its motherboards. Sitting in the bottom corner we have six SATA3 6Gb/s ports that, unlike the UD4H, are all vertically mounted and can interfere with a large graphics card being used in the bottom x4 PCIE slot. Directly above the top SATA header, you can see the dual BIOS chips. A great feature should one BIOS become corrupt due to a bad BIOS flash, the board will immediatly switch over to the backup BIOS and you can flash a stored version of the BIOS to the original.
Here is a good look at the FM1 Socket. This socket type is only compatible with the FM1 APU type proccessors and uses the familiar lever-type, pin-tensioning plate that AMD has employed for many years. In the next photo, you can see that the D2H has only two memory DIMMs. In theory, the board does allow for up to 32GB of system memory. At the top, we can also see the location of the ATX 24-pin power connector and the color-coded front panel connector next to it.
Back panel I/O connectivity has been pared down from the top model. From left to right, there are two USB 2.0/1.1 ports above a legacy PS/2 port for keyboard or mouse, one D-Sub port, one DVI-D port., one HDMI port, one Optical S/PDIF out connector, two USB 3.0/2.0 ports, one RJ-45 LAN port, two more USB 3.0/2.0 ports, and three audio jacks. Part of the "Super 4" feature set is a one-fuse-per-port architecture, where if one of the USB ports fail, it does not take out all the ports on the array.
Below are a couple shots of the VRM area of the board where you can see the 4+1 phase power and naked mosfets. Gigabyte apparently decided that this board did not need a heatsink here. If you look closely, you can see that there is an outline for where it would be, as well as the push pin holes for it. You can also see that this board only requires a 4-pin ATX power connection. Gigabyte makes use of high quality Japanese capacitors that are rated for 50,000 hours of life and rated at 85 ÂºC.
The A75M-D2H has two fan headers located close to the upper right portion of the board — one is a 4-pin and the other a 3-pin.
