Mr PC Pro takes a look at the Acorp 7KTA1 Motherboard which is based on the VIA KT133A chipset. it's a low-cost board that has some overclocking abilities that the site takes a look at. here's a snip:
"You can manipulate the "Clock by Slight Adjust" number to a number ranging from 133-166, and 100-132MHz if you are using a 100MHz FSB Athlon or Duron. The best I was able to do was 142MHz. I did hit 145Mhz, but 3DMark 2001 would crash in about a minute. So a 9MHz boost isn't what I call a super overclock, but you will still see some benefit."
