Ok, so an example, these are v1 but a different stepping. http://www.ebay.com/itm/SR0KX-INTEL-XEON-E5-2670-8-CORE-2-60GHz-20M-8GT-s-115W-PROCESSOR-CPU-/281889330127
Those should work fine with VT-d. I'll have to check which ones I have but, I'm using vt-d and passing through a GPU so I assume I'm on a working version.
