The P55A-UD6 is extremely similar to the P55A-UD4P. They are both branded with Gigabyte's Ultra Durable 3 trademark, plus they're both sexy and blue. This means the P55A-UD6 is equipped with USB 3.0, USB Power 3X, and SATA 3.0. The board also uses the 2-oz copper PCB, which I think is pretty cool. However, the boards are obviously not the same thing, so let's go and find the differences!
In terms of connectivity, the P55A-UD6 matches the P55A-UD4P. It has ten USB ports, two LAN ports, a PS/2 port, a FireWire port, a digital audio port, and the standard audio ports. Looking at the side containing the front panel connectors, we can see a few differences. However, we'll get to that a little bit later. We can again see more differences by looking at the side of the board with the 24-Pin power connector. The remaining side, is nice and empty!
For this next bit let's play a game of spot the difference. Can you see what's different about the P55A-UD6's DIMM slots? If you said there's six of them, then you're correct. I know that some of you are thinking, "Cool triple channel memory!" Sadly this is incorrect. Although the P55A-UD6 has six DIMM slots, it's still uses dual channel memory. When installing memory your first two DIMMs must go into the white slots, which are the 3rd and 5th DIMM slot. I find this a little bit strange, but it works perfectly fine. Below the DIMM slots is the 24-Pin power connector. The 8-Pin Auxiliary power connector is again located in a corner of the motherboard. Another nifty little feature is located near the DIMM slots. This is of course an onboard power switch. These are nothing new, but they're nice to have, especially when benching!
Gigabyte wouldn't give you a power switch without a reset switch. Instead of it being located next to the power switch, the reset switch is located next to the LED debugger. These are both located near the front panel connectors. In terms of PCI slots, the P55A-UD6 is fully loaded! You'll be able to use a total of three PCIe X 16 slots, however these slots run at x16, x8, and x4 respectively. You'll also be able to use two PCI slots, or two PCIe X 1 slots.
As far as front panel connectors, you'll find that the P55A-UD6 matches the P55A-UD4P. One of the few differences, is that it actually has a clear CMOS button, rather then the clear CMOS jumper. There is also two USB connectors, a COM connector, and an FDD connector. Like the P55A-UD4P, the P55A-UD6 uses a LOTES socket.
