**Official** Asrock Z68 Gen3 Extreme7 & Extreme4 thread

[bat4]

When I tested USB3 performance (when I did the Z68 review, so a much older driver was used compared to now) I didn't have any issues with the performance while transferring around 2GB of data consisting of small and large files to a pen drive. I'm also making sure I stay on top of any devices Etron break support with, which is why there is now the 1.105.394.1 beta driver.

Do you remember when I was complaining about my external HDD enclosure with JMicron chip not working properly with the Etron controller?
The funny thing is that this issue has been resolved exactly in the 0.104 drivers which broke support for other USB devices as yourself reported. (The changelog also mentions fixing the JMicron issues in driver version 0.104)
I'm quite sure that fixing the JMicron issues have created the problems.
Whatever I connect to my rear ports it is not recognized. Front USB 3.0 ports work correctly. Note that I use Windows 7 32 bit. In case of Windows 7 64 bit users it is exactly the opposite situation. The rear ports are working correctly and the front ports are having problems.

As far as 1.105.394.1 is concerned, Gigabyte has applied the same pressure on Etron as Asrock did to resolve the bugs. You can find exactly the same complaints on Gigabyte forums about the Etron controller.

The best driver remains the 0.101. I will revert to 0.101.

I have read somewhere that disabling HPET in UEFI resolves some issues with the Etron controller (file copy operation not being smooth, lag during file copy operation, disconnects). I can't verify this right now. Can someone confirm?
