I know i may be beating a dead horse here but I'll ask anyway. I have my CPU running at 3.8Ghz and temps dont go above 41C after running Prime for 7+ hours, is there any point to push it any further?
No. the 965 and 955 are made for extreme overclocking unless you have a surplus of them and are testing to see how high you can go. 3.8 is plenty for that CPU and is its known stable point. I have seen 4.0 on them before but unstable. 3.8=stable
At 3.8Ghz that's a good speed, and if your temps don;'t go above 41c that's actually excellent.
What type of cooler are you using?
IMO I wouldnt try going any higher...you might run into stability problems and/or diminishing returns.
