Ive got a Giga-byte 7xe board that only allows me to change the FSB. I purchased it with a duron 750. I've got it overclocked at 825 stable right now (110 FSB) when I change the FSB to 133 the machine sounds like its booting but I get no video. I thought the problem was with having pc100 ram, so i bought pc133 ram. But still I get the same problem, My video card is an ASUS geforce 2 mx (agp ) If you have any suggestions on why it's not working please let me know, I really dont want to make any changes to the chip its self.
