Many a chair was wet when overclockers first discovered Abit's innovative uGuru BIOS controller. It added an unprecedented amount of control and monitoring over fans and voltages all across the board. uGuru has been tweaked since then; let's have a look:

The front page is where you'll find all your CPU and Voltage settings. A quick rundown on the options available:

CPU bus speed can be set from 200-410 MHz.
Multiplier can be set from 4x to 25x in 0.5x increments. Yes, there are 50 different multipliers to choose from.
PCI-E clock can be locked at 100 MHz, or increased up to 145 MHz.

CPU voltage can be set from 1.5 to 1.85V, in 0.25V increments.
Memory voltage can be set up to 3.55V, with varying increments. For some reason, the list of available voltages is out of sequence in this version of the BIOS.
The Chipset can be set to as high as 1.8V, in 0.05V increments.
The HT voltage can be set from 1.2 to 1.35V, in 0.05V increments.

As usual, this Abit board is absolutely loaded with voltage and clock settings. None of this matters if you can't keep an eye on how the hardware is affecting temperatures and fan speeds though, and this is where uGuru truly shines:

All three temperature sensors can be monitored, with the ability to set individual shutdown and warning beep thresholds. This is exactly what I look for in a motherboard BIOS. I usually appreciate if a board has one or the other, but to have both is a huge benefit to overclockers and silent pc afficianados alike.

Just like temperature levels, voltages can be monitored to a highly precise level as well. Again, you can set individual thresholds for each component, and monitor only the ones you want.

And finally, fan speeds are monitored just the same as the rest. Interestingly, the AN8 SLI we're reviewing lists several fans the board doesn't even have. Just an early BIOS, I guess. This just shows how similar this board is to the Fatal1ty version which costs $100 more.

And here you have my favourite feature of uGuru; FanEQ. From this page, you can set voltages to absolutely every fan header on the board. You can relate the voltages to temperature levels, allowing full control over fan speeds and thus noise.

The only page left in the regular BIOS with tweaking options is the memory setting page. Thankfully, Abit kept up with uGuru here, offering an insane amount of settings to tweak.

And finally, all of these settings can be saves to various profiles. Though not nearly as robust as DFI's implementation, it is enough to quickly access five individual profiles quickly from within the BIOS.
