Although targeted at the workstation/light server market, Iwill has offered some overclocking options for the enthusiast as well. The DVD266-R’s Phoenix BIOS comes equipped with Iwill’s Smart Setting menu, which includes FSB speed adjustments ranging from 66 to 200 MHz in 1 MHz increments, and Core voltage settings ranging from 1.60V to 2.05V in 0.05V increments. These are the two main ingredients necessary for successful overclocking. Unfortunately, both CPUs must use the same core voltage setting, as the board does not have independent voltages for each CPU, such as Abit’s BP6.

The board also features Winbond’s W83627HF hardware monitor, which supports monitoring of three temperatures, CPU 0, CPU 1, and System Temp, three fan speeds, two CPU fans and a system fan, as well as all the standard voltages. The CPU temperature readings are taken from the processor’s on-die thermal diode, which provides the most accurate measurements.

In general, the boards BIOS and hardware monitoring are adequate for moderate overclocking, although you’ll be somewhat limited in terms of heatsink options because of the lack of space around the CPU sockets. On the other hand, Pentium III CPUs run relatively cool, so massive heatsinks aren’t usually necessary.
