I have a tbred-b amd 2100 and the a7n8x and when i try and change my fsb to 140 from 133, im getting no posting of the bios, I read about people getting significant jumps with the same hardware, you think it would be my memory. I have a radeon 8500dv aiw. The multiplyer is set to 14, and vcore is at 1,6. What should I do?
