Unfortunately no, I am unable to improve that last processor but I am still working on things. No luck getting TurionPowerControl working either. Will update if I get anything different (positive or negative). If anyone reading has any ideas on how to get Turion installed on Ubuntu 18 please let me know

- I'd hate to have to downgrade these servers to 16, but if I have to I will to see if anything changes.
For testing without downgrading you can install Ubuntu 16.04 LTS desktop to a USB stick and boot from that stick for testing.
All of my Dell R815's are running off a USB stick.
For testing you can just attach it to the front or back.
For production I have it installed inside at the front left side where there is an internal USB port.

Just a FYI but not all USB sticks are fast or reliable.
I have found that the "SanDisk 16GB Cruzer GLIDE USB Flash Drive" is both fast and reliable.
I buy them new off eBay and just picked up another four of them for $17.50
