I’m on a custom-built windows 11 PC (Ryzen 5 x570) and have recently been having an issue where the PC will become totally unresponsive; it’s still “on”, the fans and lighting still work, but it won’t output to the display and can’t be accessed remotely (Plex and TeamViewer both consider it to be offline). The only fix for this is a hard reset. I haven’t witnessed what happens to put it in this state.
This seems to have started after trying out the Curve Optimiser built into Ryzen Master in combination with PBO, as well as using the OC scan in ASUS GPU Tweak, which also affected voltage. The CPU OC has been reverted, so that seems to leave GPU, and I’ve dealt with weird PC behaviour related to cooling/OC with the GPU before (I haven’t been able to check because I’ve been out of town).
One strange bit about it is it’s seemingly random nature. It’s never entered this state under load; it only ever happens more or less at idle (my PC is on all the time because it doubles as my Plex server)
EDIT: I’ve removed the GPU OC from ASUS GPU Tweak, which had messed with voltage. So far the hard crash hasn’t happened again, but I’ll try to remember to update this again if it does occur, for the sake of future googlers
EDIT 2: It’s been about a month now and the issue still hasn’t occurred, so I’m pretty confident it was the GPU OC
Ah yeah I should disable XMP as well. When you say power saving, are you referring to the Windows power modes?
Not the Windows Power settings. The AMD software has power savings modes which automagically throttle the cpu either by parking cores or by reducing bus speed or by reducing core processor speeds. Some memory sticks will advertise an XMP profile but different bins will perform differently. The trick to getting an overclock or edging out performance is to maintain stability for as high as your hardware will let you go. Due to the problems you seem to be having and the stability you want, don’t pull your hair out over a few MHz of performance.
