I've got an Ryzen 1700X paired with the Gigabyte GA-AX370-Gaming K7 (new F10 EFI, happened with F7a too), CPU is overclocked to stable 3,9Ghz (but it happens with stock frequency too), C-States turned on. Everything works fine, no problems with hardware or system except one little but annoying thing. Whenever I wake my computer from a longer standby, I can hear that fans are much faster than usual. I can also see CPU temperatures going up every few seconds a bit more. CPU wakes with normal temperature, then goes 10 degrees or so up, goes a bit down, afterwards another another 10 degrees or so up, then down again. This goes on until the CPU reaches very high temperatures. The computer eventually just turns off (directly off, no shutdown or anything), probably hardware overheat protection. While observing this, there is no visible CPU load, and from what CPU-Z tells, no higher than usual core voltage either. Still, this happens every time I wake my computer from a standby that lasts longer than a few minutes. If I wake it from short standby, it doesn't happen. If I restart the computer before it turns itself of, everything goes back to normal. Does anyone know this or have a solution for it? Maybe some EFI setting that is the culprit? I'll gladly give more information if that helps. I didn't really touch any setting I know of that could be responsible. Right now, standby is kind of unusable, and that's a shame, because I used or could use it quite often.
