Tried lower clock, thanks the advice! Now its not crashing, just the ratio of rejected shares a bit more than expected. I should try other configuration.
Crashed again with CORE 1800, MEM 2100, PL80.
In the log:
Stratum thread exited.

Yes, you are right, I have much better power consumption with locked core and without PL settings.
But now I still have very bad efficiency ratio (around 93%). Accepted 56 and the rejected is 5.
Invalid or Rejected?
Rejected = problems like submitted share to slow or bad internet. (not on the best pool for your location? Poor WiFi or bad LAN Cable? A router/modem that is melting or just made of crap?)
Invalid = to much overclock.
%93 is not grate but it’s not insane so my guess is try a closer pool.
watch a Son_of_a_tech video about choosing the best pool
Also 60 shares is not a lot to build an average from
((sometimes on boot I get a bunch of bad shares, then it doesn’t miss a beat for days witch I think is because of my less than ideal network config or a time server issue))
Invalid!
Thanks your advise!
Finally I switched to other miner, I cant set the overclock setting fine.
Only worked with low MEM settings and with this cant produce more than others, or may be a bit worse.
On my 16/20 series nV cards with GDDR6 run anyware between 2133 & 2366
most of the slower ones are Samsung and the faster ones seem to be Micron.
“Low mem settings” are better than bad settings.
(if your over 29mh on a 1660ti then your not doing to bad)
33mh from a 1660ti is insanely fast, on my 3 msi 1660ti’s I get 30.8mh stable for months with Micron mem at 2366
My 3060ti with Hynix GDDR6 only does 1666 so count your self lucky.
tough one thing to take a look at if you feel the memory isn’t performing is memory Temps (I know, I know, we are hassling the nvidia support staff in the dev support forum about allowing temps in the linux driver there response so far is it isn’t even in the windows driver, we pointed out that it’s a bad idea to lie about code to a forum full of devs and sys admins but anyway)
Maybe your thermal pads are letting you down or maybe it’s poor cooler design.
Though I believe you probably just need to be more realistic and expect the performance that is normal for the device if you had 1660 Supers you might be getting 33mh but 1660ti’s are more like 30-31mh
in my experience
Thank you very much your advises, I really appreciate!
At the moment I try with different miner with different settings.
Its not fine tuned and run only about since a hour, but this configuration looks very hopeful.
An overclock can take a few days to dial in.
Get it stable for a few hours but don’t be surprised if you check back 2 days later and find 1 invalid share.
If that happens just drop it a little more and wait.
If this doesn’t happen you might even be able to go up a couple more mhz.
Eventually it’ll settle down and you’ll have found max stable clock for 24/7 OC.
