Interpro Microsystems took my order for Rev2.0 board today. I kept reminding that I need the Rev 2.0 until the point they told me to not to ask again because they got it. I paid them already. I am pretty sure it is the right one because the sales rep got back to me confirming the details with SM. SM also updated their specs on H11SSL-i which I ordered supporting 3200 DIMMs on rev 2.0 board. Still the PCIE is 3.0 but that will not bother me considering the cost.
