The most impressive voltage offering on a 650i SLI motherboard - Up to 2.375v for CPU! This is some mad number indeed, Gigabyte is trying really hard to make a statement about their boards doing overclocking.


 

Even Frequency adjustments for the Graphics PCIE slot up to 150MHz!

Finally, a very familiar and common Memory Timing Adjustment page that we've seen on other 650i SLI motherboards.

 

One of the feature that this motherboard includes is the saving and loading of CMOS options, which is becoming common, but which not all 650i SLI boards offer.

This saves me a lot of time when playing around with overclocking settings.

 

Overall, the BIOS is very strong in terms of overclocking options, in many areas of voltage adjustments. This board has surpassed it's competitors, offering adjustments of voltages some boards have neglected, and higher options for the detrimental ones. Here's a summarized comparison table which may reveal a lot for the overclocking-oriented users:
