Looking at this guys results:

on a gigabyte extreme, he says he can't boot beyond 222bclk and had to set it higher in setfsb. So maybe that's what we need to start doing for beyond 221bclk. I'm guessing there is a 4ghz qpi limit as around 221-222bclk you are reaching the 4ghz qpi wall that everyone talks about. Maybe asus can address this in the next bios or tell us how to get around it. I haven't seen the dfi or evga having problems booting past that bclk, so maybe it's a bios fix.
