I just built a friend a computer and went with a A7V133, Ordered the board and a 1 GHz 266 processor, Set the board up in jumper free mode and it booted up on his old harddrive as a 750 MHz, Tried to change it to 7.5X133 and it locked the computer, The highest you can get it to go with a SK6 is 855 MHz, Could it be newegg sent me a 750 for a 1 GHz processor
