No idea why your RAM speed is misreported.
How are the 6 sticks shown in System Information?

If you restored from a "real" MacPro 5,1 backup, what is the RAM speed on the "real" Mac?

I restored from a real mac 5.1 and on it it was 1333 Mhz. But restore wouldnt have anything to do with this i think.
