BIOS and Overclocking
Although the BIOS on the AT3IONT-I Deluxe is limited Asus has made sure you still have quite a few options for performance and of course for overclocking. Dropping in to the BIOS on the Advanced [jumper free config] screen you can see that despite being an Atom CPU you can still kick things up a bit right from a single page. In fact Asus offers a very simple overclocking feature for the Atom 330 but having a few present overclock profiles available for you. In this shot you can see the 2GHz settings loaded.
The rest of the BIOS is very slimmed down and only provides basic controls for peripherals, the ION GPU [frame buffer etc.] and also the typical USB controls.
As usual Asus still has their Q-Fan controls although I am again at a little bit of a loss here; if this is meant to be fanless and silent, why the need for the Q-fan controls? Still they are nice if you are intent on overclocking the CPU and GPU on the board as that little extra bit of cooling can mean the difference between success and failure.
Overclocking the Asus AT3IONT-I Deluxe was very easy. As we told you above there are preset clock speeds set up in the BIOS. We picked out the fastest one [2.1GHz] and started playing around. Now as we were not using any type of active cooling on the heatsink our 2.1GHz efforts did not succeed, but dropping it by 100MHz did. We were able to run all of our tests at 2GHz with no active cooling and no issues. This is not bad at all for the tiny little Atom and the nVidia ION. We are fairly confident that with even a small fan on the heatsink you could get to the 2.1GHz mark and perhaps even more with a modded BIOS.
