BIOS and tweaking software
The Mini-ITX form factor doesn't exactly scream overclocking, but Albatron has produced some decent enthusiast boards in the past, so we were curious to see how the KI51PV's BIOS stacked up.
Surprisingly, overclocking options are included. Users can drop the CPU multiplier and select HyperTransport clock speeds between 200 and 450MHz. There are also a number of memory speed options between 100 and 250MHz, along with bus multipliers for the HyperTransport links between the north bridge and south bridge chips and between the north bridge and the processor.
Voltage control is really the only thing missing from the BIOS's overclocking options. The ability to manipulate processor and memory voltages is essential for serious overclocking, but then, the KI51PV's limited heatsink compatibility and lack of a PCI Express x16 slot will probably keep it off the radar of serious overclockers.
The BIOS does provide a decent amount of control over memory timings. We couldn't get the board stable with a 1T command rate and Turion 64 processor, though.
Given the KI51PV's suitability for small form factor systems, I was really hoping the board would offer robust fan speed control in the BIOS. Unfortunately, intelligent temperature-based fan speed control is nowhere to be found.
For those who are a little uncomfortable poking around in the BIOS, the KI51PV offers limited support for Nvidia's nTune system utility.
nTune can be used to set a handful of memory timings, adjust HyperTransport clock speeds and bus multipliers, and even overclock the onboard graphics. However, the app's voltage control options are all greyed out.
nTune also offers a hardware monitoring utility that tracks temperatures, fan speeds, and other variables. The KI51PV doesn't report system voltages to the app, although it should be possible for Albatron to add more extensive nTune support with a future BIOS update.
