Re: p5b + e6400 + 2gb corsair never been clocked :(
XDanger, the NB runs pretty cool but I did add a 40x40mm fan on the NB & SB. From what I have read if your OC the ram 1:1 stay out of the 360 to 400 range because of the strap it runs the NB up pretty hard and generates a lot of heat. Once you get above the 400 range the timings are relaxed on the NB thus bringing down the heat some. I hope I made since.
stevemedes posted a great link that will help explain it a lot better.
