For sudden reboot issues, could be some power protections tripping? For me that showed up as shutdowns (that require turning the PSU off for a minute), but maybe depending on various components and could result in reboots as well? PBO seems to result in some wild power spikes that don't ever happen with manual static OC. Try raising various overcurrent limits, that worked for me.
