and I tried it at different times on different video cards for at least 5 years, initially I tried to overclock the monitor, but now in 1 week I have 2 cards changed 5500xt I sold it and now I wanted to flash rx480 with another BIOS and to disable signature verification the driver needs ati patcher and it did not help as the patch after the reboot the driver does not start. even atikmdag-patcher-bios.exe which patches a lot less does not start, and then I remember the story that this utility has never worked for me not on nvidia not on amd not on win 7 and win 10 want to understand why this is? what could be the problem ? I also disable HPET
I want to know what files the patcher replaces how it works, what to understand why it does not work for me ?

What exactly are you using the patcher for? The patcher is for specific limits, mainly DVI and HDMI 1.x pixel clock limits, and it also bypasses the BIOS signature check for Polaris GPUs. If your card doesn't boot with a modified BIOS after using the patcher, then the BIOS is not compatible with your card. The patcher only modifies atikmdag.sys/amdkmdag.sys, which is the main kernel-mode device driver.
