mikelou26: I explained in your last post asking this question that the AGP speed will drop back down to 66MHz when you use the 133MHz FSB. The BIOS automatically makes the switch.
In any case, if you have managed to get your system up at 133, the AGP would be operating at 89MHz which the GeForce is perfectly capable of handling. If you managed to get it up to 140MHz, it would be only 92MHz.
Unless you managed to get your system running at 187.5MHz FSB along with 125MHz AGP (which I highly doubt.....your P3V133 doesn't even HAVE that setting), you wouldn't even be able to boot.
