This bug can prevent you from attaining your max OC cause often a board will hang in the boot process, whereas once in windows, it is stable enough to get a validation. And there's no work around cause setfsb doesn't recognize any x58 giga board.

Come on man, you're so sure of that?

ICS9LPRS18BKL with setfsb works perfectly.
