is PCI express x16 MOBO interface compatible with PCI Express 2.0 x4 RAID Controller card?
I am installing server 2012 software on an old machine- existing RAID card is not recognized and no drivers available, also will not recognize the 3TB drives.

The question should be addressed to the RAID controller manufacturer. You want to know if it's compatible with your motherboard and if it supports drives larger than 2TB. It should be compatible with the PCI Express slot, but it probably is not supported by the motherboard.

Ask the manufacturer. Most PCI express 2.0 cards work on 1.0 interfaces but they go at half the speed. Still, I think this would require extra hardware on the raid card so check with the manufacturer.
