Victor, I retract my preivious statement LOL You might also want to do the MCH mod so you have give your north bridge some volts. With this conroe setups in order to hit certain high fsb's you will need to pump some volts into your northbridge... The mod is in one of the pics in my last post.
Also, with the badaxe you can choose different fsb straps. I would stick with the 1066 strap with a higher fsb... The reason, is the chipsets internal timings will stay tighter while using the 1066 strap than they will when using the 1333.. They automatically loosen to adjust for a higher fsb while using the 1333 strap. So most people are booting with the 1066 strap and using clockgen to get the clocks up. You will notice faster superpi times among other stuff. I hope this helps:) If you want to read up on the difference between the 1066 strap and the 1333
here is a great thread from Tony.... His thread is based on the i965 chiipset but it pertains to the i975 as well...
