Update to version 12.4 or 12.5
and the issue is probably the intensity level
either change to #-I 8 for auto default or change it to -I 3

I sent two options, you changed it to what? did you try both?
try these settings… if this fails check to make sure your windows defender or or antivirus software isn’t stopping it
-tt 75
-i 1

-asm 0

I started over and read each post you’ve sent again and noticed something that I missed, you have drivers 16.9.2…
per claymore’s recommendations For 4xx cards (Polaris) Crimson 16.12.2 is recommended.
Run DDU in safemode, then install 16.12.2 and test IF THAT still doesn’t solve the issue:
Take out ALL OF the gpu’s except 1
download and reinstall the mining software, leave it in your download folder DO NOT have it on the ROOT
make sure you put an exception in the antivirus software for that folder
setup the config file and then run it.
does it work with one GPU only? if yes, load the second one, does it work, if yes repeat
IF no
try a different card , still no
you may have a bad connector(s)

@Nikalay, you’re asking for assistance in a thread that has several possible solutions to solve your problem, and I can tell (thank you for posting it without having to ask) by your config file that you posted and the drivers that you have installed that you haven’t read any of it.
Please read the last three posts by me, in this thread, and it will more than likely resolve your issues
