Well I got it today and the stepping is:

CABYE 0543 FPMW

I also, fixed my w/c loop so I am back up with my system in my sig. Problem is, I have finals and no time to test or even install my new opty for a week . But I want to know, is this a good stepping. I know CABYE 0540 are really good, so how are the 0543's?
