Regarding the PCI-E speed, you can set it to 103Mhz (anything more and there is no POST) at bios which results in 102.4Mhz.
In windows you can bump that to 103.4mhz (anything more and it will freeze) using setFSB, the Clock Generator chip for Bloodrage is: ICS9LPRS139AKLF.

The only way to go above afaik is using the hard mod of moving resistor 128 to 125.
I am going to try it tonight and see if it helps, because I kind of like this board, it will be too bad if 229Mhz bclk will be my max.
