ABIT is a very well known company among overclockers. And why shouldn't they? The were the first ones to come out with cool stuff like jumperless motherboards...
Overclocking this baby is a no brainer. Just plug it in, go into your BIOS and tweak with the settings. I used a Celeron Slot-1 300A and a Pentium III 450 MHz for my overclocking experiments. I'm happy to report that this motherboard allowed for the same and sometimes higher level of overclocking. Check out the charts below.

Stability was determined by running the WinBench 99 Suite a minimum of three times without any crashes that could be determined was caused by the hardware.
As you can see from the above charts, the BE6 is an exceptional overclockers motherboard. As a matter of fact when compared to the BH6 or the BX6 2.0, it's a bit more stable. While the BH6 and BX6 2.0 didn't allow me to go over 112 MHz bus speed on my Celeron 300A, the BE6 allowed me to make to 115 MHz bus speed. Of course, there's isn't that much difference between the two bus speeds, but every little bit helps. An important point to make here is the fact that, the only factor that limited me from bringing the Celeron to 540 MHz with the BE6 was my hard drive. I tried adjusting the PIO mode of the hard drive, but to no success.
The Pentium III 450 MHz overclocked to 558 MHz with absolutely no problems. As a matter of fact I adjusted the core voltage to 2.1 volts just for good measure. I didn't try to go any higher than 558 MHz on the Pentium III.
