While i would love to see you get into changing more settings with that nice cpu you have, the truth of the matter is, it will do no harm to leave those settings on auto. I would check just to make sure they do not overvolt themselves (in the pc health section of bios) but i doubt they will even raise the voltage above stock.
Thank you for your help overshocked, i decided to leave it at 3740 mhz, seeing as i do not gain anything really after that point, it will mostly be up to my gpu now (gtx 260), but i managed to get it stable at 1.096 vcore
So i'm going to leave it at that. temps 58/58/60/59 max, 28/28/32/30 C idle
