I just got a new AMD Athlon 4600+ x2 and was hoping to get some pretty good numbers out of it. If I over clock by just 1MHz I get a screen at start up that says "please re-setting cpu" or something like that. It says press F1 to continue, delete to enter set up. If I hit F1 I can start windows with no problems but when I check the CPU it is running at 2411MHz. So my changes are not being applied. I have never had this problem before. How do I get around this or what do I need to change?
