24/7 stable at 3 ghz vCore 1.350 in bios, 1.32 actual in Windows. Memory 667 (1:1) 4 4 4 12. Using Lawrywild's 2004 bios. Coretemp 38 38 43 43 idle 60 60 65 65 load (Prime 95) In bios all set on auto except vcore and memory timings. Eist, C1 and Speedstep enabled.

Higher speed was either unstable, doesn't mater of bios settings, or to hot for my taste, so I find above setting the most stable and reliable for everyday use. Since I use my rig mostly for video encoding it is almost 100% (for x264) faster than my old E6600 at 3.3 ghz.
