Hi all,
Just set up my new PC - AsRock Z97 Extreme 4 with an i5 4690K, running Windows 8.1 x64
I'm having an issue with all the USB 3.0 ports (additional 2x Asrock ports included), where all ports are only transferring at a maximum of 9mb/s. I have tested with a brand new Kingston usb 3.0 8GB flash drive and also my Edimax wireless stick EW7822UAC which is also 3.0. I have tried all ports - front and back and none are any different. If i plug the flash drive in to the USB2 port it achieves the exact same speed
Tried changing the USB settings in BIOS (disabling legacy etc.), updated firmware to 1.3, tried uninstalling and reinstalling chipset and the AsRock USB 3 drivers and I'm now out of ideas.
AIDA64 says the front ports are running in USB 2.0 mode, but if i plug it in to the AsRock ports it reports it at USB 3.0 speed.
Just checked transfer speed going the other way (eg. flash drive copying to hard drive) and it is working correctly (100mb/s+), so it seems to be the write speeds that are letting it down?
Hopefully someone here can help!
