When we looked at the Gigabyte's GA-8TRS300M motherboard we noted that the Radeon 9100 IGP was not much of an overclocker... so the bar isn't raised particularly high for the Asus P4R400-V DLX. Starting at 200 MHz we slowly raised the FSB a few MHz at a time, and surprisingly we were able to go all the way up to 216 MHz FSB without changing the voltages!

Unfortunately we ran into a few problems getting past that barrier, raising the voltages even at stock speeds caused the board to not load Windows... I'm not sure what the problem is, but if you're into overclocking this certainly isn't the chipset to work with.

The Asus BIOS

The Asus BIOS is a bit different from what we're use to, but all the tweaks you expect are there. The P4R800-V DLX supports TV-Output capabilities so we can select different video modes as well. Pretty cool.

There are a lot of options in the Frequency/Voltage Control, enough for the everyday overclocker. FSB can be adjusted from 200-266 MHz in 1 MHz increments, there are the 1:1, 5:4, 3:2 memory dividers, CPU voltage goes as high as 2.05V, the Northbridge to 1.6V, DDR to 2.8V and AGP to 1.6V. There's also a performance mode selection but we were not able to run anything higher than 'auto.'
