Gigabyte GA-EP45-UD3P Ultra Durable 3 Motherboard

Home PCs have reached a new plateau recently with the much heralded release of the Core i7 processor from Intel, which goes hand-in-hand with the X58 Express chipset and the motherboards built upon it. Although the Core i7 does borrow technology from earlier CPUs, there are some major changes including placing all four cores on a single die, adding the memory controller directly to the die thereby foregoing the Northbridge, and having said memory controller able to support triple-channel DDR3. Early adopters will be pleased with their performance, as we pointed out in our release piece just a few short weeks ago, but as all major updates go, this requires not only a good deal of money up front, but some patience as well, as kinks get ironed out with the new technologies.



Take a step back from the Core i7 to look at one of the motherboards from Gigabyte's new Ultra Durable 3 line, the EP45-UD3P. As its name suggests, this board is based on the current mainstream chipset offering from Intel, the P45 Express. Although we've covered this ground before, most recently with our look at two recent offerings from MSI, it's helpful to remember that the P45 is closely related to the X48 Express with support for Core 2 Duo and Quad processors as well as DDR2 or DDR3 RAM. What that means for most people is that the EP45-UD3P, as well as other P45 boards, makes for a great upgrade without breaking the bank. We'll get into the UD3P part of the name, and its ramifications a bit later, but for now here's a look at the specifications and bundle.
