I worked out the following:
With Turbo set to Auto BIOS shows CPU running at turbo frequency of 3.6 GHz (live) but after Snakeoil is started, all tests show it at "normal CPU freq of 2.9GHz
With Turbo disabled (regardless of settings for Speedstep, Speedswitch, C-states) both BIOS and Snakeoil show 0.8GHz and it definitely doesn't increase from there even under very heavy load.
Tried monitoring CPU freq with commands like;
nano /proc/cpuinfo
watch -n1 "cat /proc/cpuinfo | grep \"^[c]pu MHz\""
...not sure they are live but they match dashboard and I am confident the reading of 0.8GHz (no Turbo) are correct because upsampling in Roon to 2xDSD took CPU usage to 100% compared to 30% with Turbo enabled; where they all showed 2.9GHz
So strange that I can't achieve the CPU specs of 2.9GHz unless Turbo is enabled and strange that Turbo does is real job (3.6GHz) in BIOS, which should be low load, but not in Snakeoil under high load.
