Now i would try to get to 3.25 and see if its stable.
If it is then try higher still in 50mhz jumps. Once you come to a hiccup up the vcore one notch, see if it boots then... if it doesnt up the vcore again and if it didnt boot before it should now... not gaurenteeing anything though.
Also what are you temps like at this moment in time? Tell me this before proceeding with the above.
