OK no problem I just thought you might have been running like that 24/7.

Running a small overclock wont create much more heat, and with an 8600, you should be able to run a very low vcore (~1.2v maybe less). Why not run 8 x 450 FSB (3.6GHz) and run the lowest possible vcore for that speed, and run your ram ~1080? I have found that using the 333 strap and having Static read control and dram read training enabled, and using Ai Clock Twister on 'stronger' is more efficient clock for clock than the 266 strap without those optimizations. If you want to run SRC & DRT enabled and Ai CT on 'stronger' on the 266 strap it will take more vNB than on the 333 strap. If you run 450FSB on the 266 strap that will put your ram at 1125.
