I am on the version 1 tinkerboard (i.e. has V1 stamped on pcb, think there is a v2 version)
I have 5 volt direct to gpio with a fan. can someone who says its working try doing lscpu on their machine and show the results?

Hi Z80,

Can you make sure md5sum of /boot/rk3288-miniarm.dtb ?
My cmd replaces only this file.

Code:
linaro@tinkerboard:~$ md5sum /boot/rk3288-miniarm.dtb

yes dtb file had been replaced, i tried lscpu before your mode and got 1.5  after i get 1.6. 
i might try another psu to my tinjer and see if that makes a differnece. i also unplugged everything from the usb sockets to reduce power bit still get 1.6.
my tinker board is a v1.2 on pcb, i think there is a v2 pcb
