I would assume that as well. Yes it matters what steppings are mixed in terms of support but Intel DOES support a number of mixed steppings and OEMs like HP have shipped mixed stepping Proliant machines (I was on the fore-front of this issue with another platform so I know this to be fact). In fact there is some public documentation about this is you can stand Intel's search feature on their website.... :D! -aps
