Closer Look:

The A75-UD4H is one of five FM1 motherboards offered by Gigabyte and is the top model. It is a standard ATX form factor measuring 30.5cm x 24.4cm. The UD4H supports the full array of AMD APUs (A8/A6/A4/E2). While the FM1 APUs and motherboards are geared more toward the user who has general computing needs, the UD4H is equipped with more advanced graphics capabilities. While all the boards support AMD Dual Graphics, which combines the on-chip graphics of the AMD APUs, the UD4H interestingly supports full CrossFire with dual x8 PCIE slots. How feasible is this? I took this capability to the extreme to find out, which I will get to later in the review.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I/O panel support is very good and includes, from left to right: one PS/2 for keyboard or mouse, two USB3.0/2.0, one D-Sub, one DVI, one S/PDIF, one HDMI, one DisplayPort, four USB 2.0/1.1, one IEEE 1394a, one e-SATA 6Gb/s, one RJ-45, and six audio jacks supporting up to 7.1 channels. As I mentioned earlier, the board supports full CrossFire mode, meaning it offers two full length PCIE slots running at x8/x8. I find this choice very interesting as far as the target market is concerned. It is really featured on this board in its advertising on Gigabyte's website, along with AMD's Dual Graphics option. The difference between Dual Graphics and CrossFire is that CrossFire is the use of two discreet graphics cards being used in tandem, while Dual Graphics is the use of a discreet graphics card being used in concert with the onboard graphics of the 'A' series APU.

 

 

 

Going around the horn here from left to right and bottom to top, you first come across the front panel audio connector in green. To the right, snuggled between the audio connector and the capacitor, is the S/PDIF connector. To the right of that is an IEEE 1394a header with the cap still on (make sure you don't plug a USB into this or very bad things can happen) and three USB 2.0/1.1 connectors. In the same picture you can see the VIA VT6308P 1394 controller, and to the right a pair of PCI slots.  In the next picture are a USB on/off charger, two USB 3.2/2.0 20-pin connections, and the front panel connections. Just above the front panel connection is a 2-pin Clear CMOS  jumper.

 

 

 

Moving up the board, in between the VRM heatsink is a pair of Etron USB controllers, and you can see that this board takes an 8-pin ATX 12v power connector. On the right ,you can see the inductors and capacitors for the UD4H's 8+2 power phase arrangement, as well as the new heatsink design Gigabyte employs on the new chipsets sitting atop the board's VRM mosfets.

 

 

 

Here is a look at the socket and DIMM area. The UD4H will support up to 32GB of 1.5v DDR3 in speeds of up to 1866MHz natively (2400MHz OC), and is obviously dual-channel architecture. To the right of the DIMMs is the ATX 12v connector, as well as the TPM and COM headers. Around the board you will find four fan headers — two of them are 4-pin and two are 3-pin.

 

 

 

The UD4H has five SATA3 6Gb/s internal headers and one e-SATA connection on the back panel. Four of the SATA headers are horizontally mounted and one is vertical.
