GA-Z97x Gaming 3 - USB 3 Performance

[dz0rpw]

Hi All,

Been out and purchased an SD card that reports to R/W at 80MB/s but I can't get higher than 17MB/s. No devices are listed below my USB 3 entry in system profiler.

(Build Details)

GA-Z97x Gaming 3, Clover, Sierra, (using Rehabs FakePCUID_XHCIM and PCIID), BIOS set to Auto-Smart and X/H are both enabled).

All ports are working however all devices irrespective of port are listed under a USB 2 hub. USB 3 shows:
USB 3.0 Bus:

Host Controller Driver: AppleUSBXHCILPTHB
PCI Device ID: 0x8cb1
PCI Revision ID: 0x0000
PCI Vendor ID: 0x8086

Tried Multibeast 3rd Party and 7/8/9 and no change.

Any ideas?

This may work for your Mainboard, too.
