The 440BX was legendary for being an good chipset to overclock on. Though it officially only supported front side bus speeds up to 100 MHz, it was rock stable at 133, and, with extra cooling, often went to 150. This is one of the very few chipsets that was ever sold overclocked right out of the box. Both the Abit BX-133 RAID and the Asus CUBX series advertised on the package that they supported 133 MHz FSB. The BX was one of the few chipsets that could be counted on to overclock to 133, rather like a Celeron 300 could be counted on to do 450 MHz, or, back in the early days, how a '486-25 could be counted on to do 33 MHz.
The BX was also the last Intel chipset to natively support ISA, which, despite being slow, is to this day fast enough to keep up with things like a 56k modem.
