Clicking on Auto, or default settings should give you a system which boots, 
but may be suboptimal compared to the capabilities of your hardware.  I don't 
have the same hardware with you to compare notes, but the way I go about it is 
I increase the RAM frequency to the maximum the DRAM manufacturer recommends, 
dialing back the DRAM timings as necessary to ensure stability.  I also 
increase the CPU frequency, by adding to the CPU voltage offset but again 
within reason - the idea is to let it run at frequencies it was designed for, 
rather than cook the chip.  With minimal tweaking like that I get a high 
performing CPU/RAM combo, but always with stability, way below maximum 
voltages and frequencies.

The other thing I avoid is clicking on any auto-O/C 'performance' settings.  I 
have found they increase the voltage unnecessarily and often create an 
unstable system and a noisy cooling fan.  It goes without saying an 
aftermarket CPU cooler is a must before you start pushing your MoBo.

If you google and check youtube.com you'll see what people get up to with your 
hardware, but always use your judgment and err on the side of caution.  
Overclockers tend to boast how close to destruction they have pushed their 
hardware, until the next model is released - so their settings are typically 
an example of what you should avoid rather than emulate.
