Thank you johnnie.black, that was very helpful.
Here are my results with boost on:
real 0m46.527s
user 0m46.517s
sys 0m0.000s
and here with boost off:
real 0m55.429s
user 0m55.396s
sys 0m0.017s
Looks like boost is working! Thanks for your help.
I am having the same problem. I have the same CPU as OP on a Super Micro X8SIL MB and when I watch the CPU frequency in SSH it varies from 1200 Hz to 2668 Hz but never turbos to 3200Hz. Turbo boost is enabled in the bios just like OP's photos show.
Is UnRaid unable to take advantage of turbo boost speeds on all hardware?
