Now we move along to the board itself, which is where all your hard earned dollars are going. The board is based around the traditional dark blue full ATX PCB that GIGABYTE uses for all its latest boards. The layout follows the traditional GIGABYTE design.
The 24-pin ATX power connector is located behind the six DDR3 memory slots which are coloured light blue for the first triple channel bank and white for the second triple channel bank. The 4/8 pin EPS power connector is located behind the PS/2 towers on the upper left hand side of the board. This is the optimal layout for the power connectors as it keeps the bulky cables away from the CPU and other vital components.
On the lower right side of the board we have six blue SATA connectors and two white connectors. The blue SATA ports are connected to the ICH10R. Supporting RAID 0, 1, 10 and JBOD, you have what you need for the basic RAID/performance storage arrays. The two white SATA ports are controlled by the JMB368 PCIe x1 SATA/PATA controller chip which gives the board its IDE controller since Intel are no longer integrating IDE channels into their ICH's.
The board is equipped with a 2x6 phase voltage system working in parallel; these are cooled by the heatpipe that also cools the ICH10 and the X58 IOH.
The rear I/O ports on the UD4P are slightly different compared to the DQ series. One of the big misses on this board is that it has no eSATA ports on the rear I/O and with no break-out brackets like we see in the other GIGABYTE boards, this one misses out on eSATA altogether. On the plus side of things, the board has a Clear CMOS reset button which means if you do end up getting this board into an endless loop with a failed overclock (which happens with GIGABYTE boards), you can simply press this button and reset the BIOS to its defaults.
Lastly, we are down to expansion slots. GIGABYTE has done a fantastic job with keeping a variety of expansion options. There are a total of three PCIe x16 slots; two are blue and one is orange. The two blue slots are capable of full speed x16 allowing for Crossfire(X) and SLI. If you want to 3-way SLI you can put a graphics card capable of 3-way SLI into the orange slot which will remove 8 lanes from the second blue slot and divert them to the orange x16 slot, giving you the 16/8/8 setup.
At the very top of the expansion slots there is a white PCIe x1 slot and just below this is a orange universal x4 slot; this can be used to put an extra graphics card in if you want four GPU's or any other PCIe devices that you wish. It's perfect for a x4 or x8 SATA/SAS RAID controller, but remember that it is limited to x4 speeds and runs of the ICH10R, so it will be slower for graphics cards. Lastly, there are two white PCI slots for legacy expansion.
