OK, thanks for that.
One thing to note, is that you will not reach a "good" overclock with that system. The board is not designed to be overclocking friendly as it's a basic board, and your stock cooling will not handle the higher heat load from even moderate overclocking. This should at least point you in the right direction, though I would strongly recommend not changing ANY setting until you know EXACTLY what it does - research is the key, and ASK if you are unsure. With that said ...
First thing to do is to reset the auto overclocking back to the standard settings, then set up your RAM properly according to the manufacturer's specifications - speed, voltage and timings.
Next, set up the rest of your voltages manually - CPU Vcore, northbridge, and so on. Set them to the standard voltage for now, and raise them later if necessary - "Auto" will normally overvolt massively when it's not needed.
Start upping your FSB by about 20MHz at a time. Test for stability using Prime95 or OCCT - the way I like to do it is to run OCCT's Linpack test for 20 minutes each time I up the FSB, then reboot and up it again. Wuen it becomes unstable, add a little more voltage. I'd keep the voltage below around 1.375V for that chip, so stop when you reach there or when you add more voltage and it doesn't stabilise your system.
You will most likely need to adjust your RAM speed to keep it at or below the rated speed as you increase the FSB, as they are linked.
