@Lost_N_BIOS - Setting the value to 0.01 for "IA AC Load Line" and "IA DC Load Line" seems to have solved the problem and now everything is ok. When I run the Aida stress test the CPU is at 4Ghz, the temperature is up to 60 degrees which is 10 degrees less than before and VCore voltage is ok. Everything is the same when I start the Cinebench. Both LAN ports are working and the MAC addresses are set properly. I think that everything is set up properly now and that there will be no problems with the work.
I did not expect anyone to take this much time and knowledge to help me and solve the problem with my BIOS. Thank you very much for everything and if I can help you with anything, feel free to contact me.
