Gigabyte X58A-UD9 and GTX480 Quad Sli Review
BIOS and Overclocking
Of the two BIOS available Gigabyte use the AWARD BIOS. The UD9 shows its overclocking leanings with the M.I.T (the overclock menu) is the first option available, rather than on the right hand side like it is with some variants of the AWARD. Whereas the AMI BIOS has most of the overclocking options setup on a single page, the M.I.T has them spread around a little within the submenu. It takes a little getting used to if you're more familiar with the AMI BIOS, but everything is neatly labelled and navigation is a breeze.
Before you get excited that Gigabyte have some secret trick to unlock your processor, we're running the 980x in this, hence the high multiplier.
Everything you could desire to get a good overclock out of your processor is available to tweak. As it is so easy to navigate hopefully we'll see a nice result.
As always with a good overclocking method the first thing is to see how far we can push the BCLK and so we know if this is a real lunatic overclocker, or something that will need a little massaging.
One thing to note before we get to the figure, is that if you have all four PCI-e slots populated then the ability of the UD9 to push the BCLK hard is greatly reduced. This is hugely surprising given its status as an extreme enthusiast board, but it's something to be aware of.
207MHz was the limit of the UD9. Initially this might seem a little disappointing, but the reality is that with most memory topping out just past 2GHz, and with the i7 Extreme's being happier using the multiplier to overclock rather than BCLK, it should be more than enough for our needs.
And so it proved. 4.648 GHz being a new record for this processor, beating the Rampage 3 Extreme by 38 MHz. This is entirely on air and, as you can see from the CPU-Z, without insane voltages. Not the kind of thing we'd want to run 24/7, but my word it's stunning.
