I have a MSI Z77A GD65 mobo, and in Windows 7 USB 3 is running very well with up to 120kb/sec on my USB 3 hdd.

Same hdd, same USB 3 port, but in windows 8 only 40-65kb/sec. I have tried to install the Intel USB 3 driver from MSI, but I get a warning, that the Win7 x64 driver has some compatibel-problems, and there is no solution yet.

Anybody know of a beta USB 3 driver for Windows 8? Right now I am using this version 6.2.9200.16420.

Allso my USB 3 HUB is only running USB2 speed in Windows 8, so something is not right.

You must have meant mb/sec, not in/sec...as kb/sec would be terrible.

Click to expand...

yes, you're right. mb/sec. But still it is slower than windows 7, and for some reason, it is not possible to use windows 7 driver for this?
