BIOS
The BIOS is fairly regular for an ASUS motherboard and offers plenty of manipulation of various voltages.One feature that is missing is the ability to save the BIOS profiles. Entering, say, 30 parameters and then losing them should the CMOS require clearing would be the very definition of irksome.
Here you can control the parameters relating to the onboard graphics, including HDMI audio.
Maximum and minimum
We've photographed the minimum and maximum frequencies/voltages in pairs of two screenshots. Enlarge them for a clearer view.
The GPU engine clock ramps all the way up to 1,500MHz. Most users will be looking to push to 1,000MHz if overclocking from the default frequency of 500MHz.
The DDR2/3 memory-controller on the Phenom chips isn't as sensitive as Core i7's. Still, you wouldn't want to be pumping much more than 1.9V through it on a long-term basis.
