I understand you would like to know if the Intel® Xeon® Processor E5-1603 v3 supports Windows 7*.
Let me apologize for any inconvenience this issue may be causing to you.
There is no actual driver we can provide for Windows 7*. If the motherboard you are going to use with that CPU supports Windows 7* then there should not be any problem. Please check with motherboard manufacturer if the specific motherboard you are going to use supports or not Windows 7*.
