Error 1017: Cannot login to the Everquest server.

[Digitalmocking]

I've got a Ryzen 7 5800X3D, core ratio is set to 34 and locked, I don't think it's changeable on this CPU or motherboard (Gigabyte B450 Aorus M). I've disabled all the game boost and auto boost properties I could find for my motherboard and 19 times out of 20 that I try to launch P1999 I wind up with the error 1017 pop-up.

Any ideas on how to fix it on this CPU? It seems totally random, sometimes it'll work, but 95% of the time I get the error 1017 and it'll never work until I reboot. If p1999 launches on the first shot, it's fine, but I've never gotten it to work once I see that error.
