    Hello, I thought it was the problem of the AMD drivers that most of my games crashes and it turns out, it was the boost clock of my msi 5500xt oc 4gb. When I underclock it to 1750, everything works fine now. No more issues at all.

    Please, if anyone can modify this bios below, any help would be greatly appreciated. Just lowering the Boost Clock from 1845 MHz to 1750, or anyone can please point me to the right person. Thanks!

    RBE doesn't support 5500XT for now :(

    Did you try opening up the voltage limits?

    Nope, don't want to do that since I want to be more conservative on electricity

    Try opening the power limit up to 20% and test stock settings again.

    Are you using some multirail PSU?

    According to your PSU spec, it has 18A per rail, offering 216W per rail. The GPU card you have uses 130W, but will have higher transient moments where it uses more. What is probably happening is that your underclocks are helping for your PSU not to max out on the one rail.

    Make sure the GPU is not sharing a rail with anything else. If it is, you are losing power capacity to the GPU.

    (Also remember that CPU, RAM, and other devices are also tapping the rails, which is why you should endeavor to try and isolate the GPU on it's own rail)

    In the future, buy a single rail PSU. They avoid this issue.
