Not a problem.
If you're doing the overclock now - let peeps know that you only want a modest clock - maximum 4.3Ghz - stability is key for you, no need to push it.
You may find that it runs 4.3 on auto - just by upping the multiplier - (had a quick look at 'AI Tweaker' in your BIOS - it really is simple process compared to my p67).
You will also need to set your memory - easiest to use the XMP. But when clocking, if using manual, in the 'Ai Tweaker - you can choose the frequency easily enough - but timings will require more of a search (someone will explain - but I doubt your memory is running at full speed).
Keep your energy saving settings (speedstep etc if possible - shouldn't be an issue with a moderate clock) - and whatever you do don't be talked into using an auto overclock tool (you wouldn't on these forums without a fight breaking out between members).
Should be relatively straight forward - got to go now - best of luck.
