| AMD software is often utter trash. I am a diehard fanboy of their GPUs, and have been since they were still ATI but I had to finally purchase an nvidia GPU because of how bad AMDs software quality is. My powerful 5700XT spent two years basically broken, because the default, driver provided fan curve locked the fan at 27%. For two years, I couldn't figure out why my GPU constantly crashed, because it was overheating, because the default fan curve prevented the GPU from keeping itself cool and it would eventually just give up. That diagnoses was complicated by the fact that AMD GPUs just resetting is very common. There's a watchdog timer in Windows that resets parts of the GPU stack because Microsoft is traumatized by 60% of Windows Vista BSODs being caused by bad nvidia drivers. Apparently sometimes if you increase this watchdog timer, the GPU eventually finishes whatever was giving it trouble. But I still love AMD, and the ryzen line is a great value in the mid range. So I bought another AMD CPU and am very happy with it. But it somehow included software and this specific auto updater utility. Which I don't need, since I don't want to update the drivers for a GPU that I shouldn't be using (maybe except some video encoding lift, but my GPU can do that too). But I could not figure out a way to kill or prevent this stupid little autoupdater utility which always steals focus, for no reason at all. It shouldn't even be popping up a CLI! Windows task scheduling is incredible and would do this without a problem, and give you all the infrastructure to notice this was happening! |
I still need to figure out why the internal curve is not working, but have not gotten around to it because I like my controller so much. The novel bit is that as I was writing it I had an epiphany "Why a curve? What we really want is to close the loop. Set an ideal temperature and figure out the fan speed to maintain it" So my controller has a cute little PID loop to do just that. realistically it never works as I imagined. At idle the temp is lower then the set point at the slowest fan speed and at load the full speed fan keeps it ~ 10C higher than the set point(perhaps this means my set point should be higher?). but sometimes I get that goldilocks midrange load and it works great.
