In this tutorial Im using oem configuration compaq 500b mt with foxconn 2a8ch,this mobo can't be overclocked in bios so we are going to use OC software...
1. download SetFsb http://www13.plala.or.jp/setfsb/download/ver22/setfsb_2_2_134_98.zip
2.install it and reboot your pc.
3.Run it and select pll: cv183apag (if u have different mobo your pll is probably different).
4.multiplier is x13.5 so u should start off with 220 fsb and slowly add few more.... this proc goes up to 3.2Ghz on stock cooler but I wouldn't recommend going above 3Ghz...
5.enjoy your overclocked cpu
there is a nice program for monitoring your cpu temperature AIDA64 you can download it here: http://www.aida64.com/downloads
ps. if u want SetFsb to automatically OC when u boot up folow this tutorial: http://www.ehow.com/how_12032951_keep-setfsb-settings-after-reboot.html
