I got to say that I did enjoy using the board but I eventually killed it while trying to sort vdroop issues using the known vdroop mod!

Anyway, every cloud has a silver lineing and Im now using a Asus Maximus and its much better with my qx9650. Votage is stable with almost no vdroop. C1e works, half mutlipliers work, and Im now running at 4.2Ghz @ 1.49v - my IP35pro would not even boot vista at that speed even when I put the actual voltage up to 1.55 (prob cos it vdrooped so much)

So from my experience - I would recommend the maximus anyone with a qx9650. Other chips appear ok with the ip35, the biggest pain is that vdroop.
