The LGA1156 and LGA1366 are very different animals indeed. Here is my initial run and OC with the new proc and mobo. Any suggestions? I wanted to conquer linx with HT on and a good OC first, so that the rest would be a peice of cake and I will have developed some of the experience necessary. I have alot of research and tweaking to do....
4.4GHz is looking pretty good. I knew that chip would go faster with better cooling. Thou I'm surprised your having to shoot 1.44v to it. What mobo are you using?
Running at that speed, and possibly faster, you should consider getting some faster ram. A nice set of DDR3 2000 8-8-8 modules like these would run at 7-7-7 or lower at 4.4GHz and they may just help you get more out of the cpu
