It literally took me less than a minute. I searched the name of the board and clicked 3 times (at the intel site) to reach that same PDF.
I don't trust that if one model CPU works than chances are that line will work. Its all microcode dependent. Some features may not work, etc. Its worrysome to me to say that, though being fairly educated on these subjects, I understand what it can mean. Others may not.
I don't know what he wanted and jumped the gun in my posting perhaps in my curmudgeonly ways. You also thought some dude was faking his CPUz screenshots with absolutely no reason to believe he would do that, so, can't say I have the utmost faith (but some) that we know the underlying ways/meaning.
Again, not really about Xeon's so.. trying to digress here.
