I got amd xp 2800+ over a year now...and i was always running on 166mhz fsb and now i tryed to change to 200 and it didnt work so i had to reset the mothermoard and now its running at 1.25 intead of 2.1 and when i change my fsb in bios from 100 to 166 and then go in windows it shows that it hasnt been chnaged...it shows that its 100 I tryed setting it up to 200 again and my comp still loaded so its somthing wrong with bios...does any1 know how to fix this or know any good program to do it in windows (fsb+cpu speed/overcloack)
