I have read many guides and pretty much understand what I need to know.I have been balancing performance overclocks with temps to ensure my pc performs at top efficiency for the long haul without damaging components. I have done stress testing with various programs for stability and performance. I am quite happy with the results, but I am always looking for various hints, techniques, and suggestions to perfect my knowledge. Hopefully as my experience matures, I can help others by being correct in my suggestions and assumptions in furthering others knowledge base.
I'm running at the same FSB but going with 200x18. I'm curious what VTT and Vcore you're using now? At 3.6ghz my CPU idles in low 30s. What cooler do you have? I should think it could idle lower than 46C as I'm only hitting as high as 52C under max load in Prime95. My Vcore is currently 1.178V and VTT is... 1.7V? Damn I can't remember exactly, it might be lower. I've read that for ~4ghz it needs to be around 1.8/1.9V. I didn't touch PLL voltage.
