i just set the PCIE to 107 and cpu fsb to 240. Everything is going fine but hw do i know if its safe and stable now?
You can use Prime 95 to stress test your system. Blend tests test the whole system for stability and small fft tests just stress the CPU. I do not know what RAM you have but if you can run small fft tests fine and not blend tests then it is your RAM holding you back.
Just keep your RAM at or below rated speeds while overclocking the CPU.
