We have tested the throughput with AMD hosts and achieved a throughput of 354 MBps. Does your PC show the same behavior for all USB 3 Devices (say a hard disk or a USB Camera that do not use FX3)? Please check. If so, it might be a machine specific issue.

It is true my PC only run up to 120MBps for other USB3.0 device.
This seems to be machine specific issue. Please try on any other system. If you are not seeing the same issue then it surely is problem with machine. If yes then please check with chipset vendor.
