Board Layout and Pictures
Jumping right into the UD4H, starting in the top left corner behind the rear I/O panel you have an 8-pin power connection for the CPU. Next to it is one of three four pin fan headers around the CPU socket, the other two are below the CPU socket and the main fan header is white in color to help it stand out. Considering I have had issues in the past where I hooked up my CPU fan to the wrong header, color coding that one specifically was a nice touch.
Over on the top right corner, the first thing you are going to see is the bright red power button that is directly next to the four DIMM slots. Around that power button you also have a smaller blue reset button, two BIOS switches and a clear CMOS button. Next to all of the buttons are 16 pads where you can check the voltage on 8 different motherboard voltages with a multi-meter, this is important because onboard voltage readouts can be a little less accurate compared to a dedicated multi-meter. Down farther, but still next to the DIMM slots you have a 3 pin fan header as well as the 24 pin power header. In with those headers you have the LED diagnostic readout as well as a bright red USB 3.0 header for hooking up your front panel USB 3.0 connections. It’s a small detail but I would have liked to of seen the fan header here be a 4 pin as well, most of the competition is going to this now.
Down in the bottom right corner of the UD4H, next to the chipset cooler you have eight SATA connections. Six of those ports (the black ones) are SATA 3’s ran on the Intel controller while the other two (grey) are run on the Marvell 88SE9172 chipset. There is also an optional power connection here that uses a SATA power cable, something I rarely see but welcome. From its location I can’t tell if it provides additional power to the DIMM slots or the PCI slots or maybe both. Below the SATA ports you have another four pin fan header (our 3th 4-pin and 5th total). On the bottom corner you have a color coded front panel header for hooking up your LEDs, power, and reset buttons. Next to that you have a second internal USB 3.0 header, something I don’t see often as well as three USB 2.0 internal headers.
In the last corner, continuing from before on the right, we have the COM and TPM headers as well as our sixth fan header. The last header in the bottom left corner is the front panel audio connection, this is in a much better location that older Gigabyte motherboards, no have to run the cable over or under a video card this time around!
The rear I/O panel on the UD4H is completely packed full. You end up with four different display connections alone with its DVI, VGA, DisplayPort, and HDMI ports. To go with them you have an optical audio connection as well as the fairly standard 6 port audio connections. You get one 10/100/1000 Ethernet connection to keep yourself connected that runs on an Intel NIC. It’s great to see more companies using the Intel NICs. Beyond that you get two eSATA headers (in red) and six USB 3.0 ports (in blue). They also included a legacy PS/2 connection as well for those who want to run their older keyboard or mice.
To match the red trim on the cooling of the UD4H, Gigabyte also went completely flat black on the entire PCB. I think the only thing I might like better than a black PCB is a white one, or orange… ANYHOW including a black PCB shows that they are listing to what people want. Now for that white and orange model!
