I know this thread is extremely old, and vicoorr is probably long gone by now, but I have almost the same problem.
I cant get over 3ghz, cant get over 200 FSB, tried increasing vcore up to 1.55v (max) to no avail.
Memory is 2-3-2-5 HTT@800.
Only way I can get to 3ghz is running multiplier @ 15x and running a 200fsb.
Anyone see anything obvious, I am new so specs arnt in sig but a quick copy and paste from another forum:
