So, with your recommendations, I ran two proper Prime95's, the way it was recommended in the above link....
I was able to get it up to 2.8 @ 1.425v. It was still getting hot though, working at around 53 - 55C under load, and I stopped it after about 20 minutes to go to bed.
I'm very sure it will go more, my cooling doesn't seem to be cutting it though..
Good to know that you have had an improvement.
