You should be able to hit 4.0 easy with that chip. I suggest uppping your voltage to your cpu to 1.3 and try running a 350 FSB. Keep the mem timings at 2:8 unless your ram isn't very flexible then drop the ratio to allow for a higher FSB. You may also need to loosen your timings at higher DRAM frequencies.
Oh and
TPU caputre is much better than editing your pics in paint.
You can simply press ALT+PrintScreen to capture the currently popped up screen. Also you can run more than one instance of CPU-Z and simply Mark Area to outline what you want in the picture.
