Gigabyte EX58-UD5 X58 Motherboard


Intel’s latest chipset is fast becoming very popular despite its cost and in our latest review we get to sample Gigabyte’s mid range entry in the form of the EX58-UD5.

The UD5 is a little confusing as the PCB is actually part of the UD3 range having the same 2oz of copper integrated into the circuit board, just like its P45 counterpart. This, along with solid capacitors and Ferrite core chokes make up the 3rd incarnation of Gigabytes ‘Ultra Durable’ range. The double layered copper PCB claims to lower impedance as well as having the added benefit of dissipating heat which in turn, along with the lower impedance, could increase stability when overclocking.

Where the 5 bit comes in I am not sure but looking at the board’s specification it becomes clear that the UD’5′ is a higher specified board than both the UD3 and DS4 stable mates. In fact, it appears to be very much akin to the range topping Extreme model save for the extravagant cooling on the chipset, yet costs some £30 less than Gigabytes flagship model. This may well appeal to those who want the best possible performance yet don’t wish to have excessive trimmings, least of all pay for them. That said though, as this is an i7compatible motherboard, it has a price tag to match, weighing in at a little under £220, it isn’t the exactly the bargain basement we had hoped for but it is the cheapest of the trio we have on test today.

Quite a specification which, on paper at least, has both the Asus P6T deluxe and the MSI Platinum beat. Sporting 40 PCIe lanes as well as supporting SLI and Crossfire this board is certainly touting itself as the gamers board but the 10, thats right TEN SATA ports, should satisfy even the most ardent storage freak. Up to 12 USB ports and 3 Firewire ports make up the excellent connectivity available on the EX-58 UD5. On board switches should please the enthusiast. Support for up to 24GB of DDR3 and Dual LAN teaming round of a very complete and feature packed specification.
