The Revodrive X2 that I have in the bottom PCIe 4x slot is only running at half speed (400MB read in ATTO) vs the advertised (740MB Read). Will not be back in town until Friday SO I will have to wait to start overclocking this beast until then, but was hoping someone might have some ideas why it is only running at half speed...I have been trying to think what the cause might be:

1.) PCIe Lanes are maxed??
2.) Bios issue with bandwidth in the 4x slot..
I looked into the same issue in my UD7 VS MIVE review here:
