Any OC profiles you have saved in your bios will be still there if you use the auto OC, do check before what the max voltage is for your cpu though, I tried the aisuite auto oc a couple weeks ago and it did give me a high oc but my core voltage was at 1.54 v the max for my 6700k is 1.45v (think 1.35 max is what intel say)
This much over voltage would have caused damage to my pc if I had not noticed and carried ou using it for a period of time
