USB 3.0 speeds working as 2.0?

post #1 of 7
Thread Starter 
I have a sabertooth p67 mobo and for some reason the USB 3.0 ports all work at 2.0 speeds. I updated bios, installed the drivers and tried different 3.0 devices and still no dice :/ Any ideas?

How are you measuring the speed?

Transferring a file unless there's another way to do it?

Check all the content on this site to see if there is anything you've missed.

If everything checks out, try going to the BIOS and enable XHCI if you have the option. And, disable EHCI is you have the option. (Not to be confused with storage controller type AHCI).
Please ensure you have the USB 3.0 Controller driver installed. Drivers can be found on MB manufacturer website.

There are three points of issue,

1.) Your system

2.) Wire

3.) Device


2 and 3 are significantly more common. Check your cable, check your device make sure it meets the hardware specifications to use USB 3.0.

Try reinstalling your USB 3.0 drivers for your motherboard.

This happened to me. Even though I had installed the motherboard USB 3.0 drivers the ports only ran at USB 2.0 speeds. After I reinstalled the motherboard USB 3.0 drivers I started getting USB 3.0 speeds.
