fitlet comes with 5 year warranty that applies whatever temperature it is running in. It is next to impossible to damage the hardware by overheating.
To maintain full performance I suggest keeping CPU temperature below 90C.

I have the Mint Box Mini and found the same sort of issues with it on video etc.
Changed the TDP and Video Memory settings Video drivers etc etc...

Was feeling a little disappointed with the whole thing.
Tried some different OS including Windows 10, Zorin OS 10, Mint xfce 17.2, and others that i don't recall now.

I currently have Manjaro 8.13.1 xfce installed with Compiz and Cairo Dock running for some bling, the TDP is at 6500 and Video Memory at 512.

Can use the Mint Box just like a Desktop PC, Video playing Browser open plus tabs.
Even with the default BIOS values for TDP and Video it was ok.

I am very happy with it now!
Not sure if it is an issue with Mint or drivers but I could not get it working to my satisfaction and now it is, I was rather amazed at the difference.
Was a bit of a learning curve using a different OS but very happy now.

So if all else fails to deliver then what have you got to loose, try another version or different OS!

There were questions above about disabling cores to enable Turbo Core so I played around a bit.

I set TDP to 20000 and set number of cores to 2. Yep, both cores boost to 2.2 GHz

Code: Select all

$stress --cpu 2

#cpufreq-aperf -o -i 10
CPU	Average freq(KHz)	Time in C0	Time in Cx	C0 percentage
000	2196000			09 sec 981 ms	00 sec 018 ms	99
001	2196000			09 sec 981 ms	00 sec 018 ms	99
Enabled 3 cores. Adding a 3rd core drops them all down to 1.6 GHz, still better than 1.2. Back to 4 cores, and all 4 were at 1.6 GHz.

Code: Select all

stress --cpu 3

CPU	Average freq(KHz)	Time in C0	Time in Cx	C0 percentage
000	1596000			09 sec 981 ms	00 sec 018 ms	99
001	1596000			09 sec 981 ms	00 sec 018 ms	99
002	1596000			09 sec 981 ms	00 sec 018 ms	99
Now that would seem pretty clear, except, if I keep 4 cores enabled but just stress 2 cores, those cores will still boost to 2.2 GHz

Code: Select all

stress --cpu 2

000	2196000			09 sec 980 ms	00 sec 019 ms	99
001	1596000			00 sec 014 ms	09 sec 985 ms	00
002	1596000			00 sec 010 ms	09 sec 989 ms	00
003	2196000			09 sec 980 ms	00 sec 019 ms	99
and again, just stressing 3 drops them all down to 1.6 GHz

Code: Select all

stress --cpu 3

000	1596000			09 sec 981 ms	00 sec 018 ms	99
001	1596000			09 sec 981 ms	00 sec 018 ms	99
002	1596000			09 sec 981 ms	00 sec 018 ms	99
003	1596000			00 sec 028 ms	09 sec 971 ms	00

So anyway, it appears you do not need to disable cores for Turbo Core to work, just don't stress more than 2 cores at a time.

Oh, and a caution, the temperature of the APU rises rapidly with 2 cores pegged at 2.2 GHz, hitting 90C within a minute or so.

fmk - thanks a lot for this observation!
