1 out of 5 eggsFunctions but SLOW

Pros: Installed and worked kind of

Cons: Installed on a quad core Dell XPS. It works, but the fastest speeds are around 36Mbs. I tried multiple USB3,0 devices, and they all worked the same

Other Thoughts: I am going to order a different card

Manufacturer Response:

Dear customer;

This is a true USB 3.0 controller card and should perform at USB 3.0 speed.

One of the possible reasons for the slow transfer speed might be the wrong driver that was installed. Please uninstall the driver and reinstall it manually. Do not let Windows automatically install the driver for you. Manually choose the driver provided on the driver CD bundled with the card or you may download the driver from our website.

Also make sure that the Molex power connector is connected to a power source.

We are more than willing to provide all of our customers with prompt exchanges whenever a product becomes defective.

We are truly sorry for any inconvenience caused to you. We stride in our customers' satisfaction.
