Is there anyone here with any experience with this motherboard and the b northwood chip. I currently use the 1.6a and would like to get to 3ghz or higher with most aggressive ram settings short of 1.5 cas which the ram can be set at with this mobo. Just wondering if anyone has this mobo with a b chip in it and running above 3ghz with ram above 400mhz. Please list the CPU RAM and GHZ,MHZ achieved with it. Thank you for all your help.
