As the years have passed, the IRQ management through the BIOS has become ever more limited - in this case we are down to influencing just two IRQ's.

The PC Health status is quite important, as it is the only place where we find out that the "default" DDR2 voltage is 1.8V.

Ah, we finally get to the Motherboard Intelligent Tweaker... this is were the action is for overclockers.

When overclocking, it is important to lock the PCIe frequency to 100MHz - you can try to up it a bit (up to 25MHz) once you found out the highest stable processor overclock.

I always turn off automatic overclocking features, and I override the SPD timings manually to what I know works best for the given module I use.

Unfortunately Gigabyte is still using a voltage offset for DDR2, MCH and FSB; personally I'd prefer it it allowed me to set it in terms of absolute voltage; or at least if it showed the default values here!

I REALLY like it that Gigabyte offers eight stored BIOS profiles; when experimenting to find the maximum overclock it is very helpful to save useful milestone settings so you can quickly go back to them.

I also like that these days major vendors are building in BIOS reflashing tools into the BIOS, and that these tools can read files from thumb drives. Finally, floppy drives can be resigned to the dust bins of history!
