Re: T420s USB 3 port operating at USB 2 speed

2011-09-06, 17:24 PM

In additon, I 've read some other post from the internet regarding a similar issue, the solution was to not set the DRAM frequency to 1066 ( which i think T420s does it defaultly). Does anyone know how to reset the DRAM frequency?

Just want you folks to know that my new USB 3.0 stick wasn't working with the Lenovo drivers.  I found updated drivers below:

It has also seemed to speed up transfers with USB 2.0 devices attached to the 3.0 port.
