I've run into a strange issue recently. I've noticed that my MSI GTX 1070 Gaming X has stopped going to boost clock, and just sitting at default clock (1607 default). When, I reboot my computer, the issue goes away, and the card will boost to 2015mhz again. However, after leaving my computer on for 24hrs+, the issue comes back and the card will again refuse to boost. Any ideas why this is happening? Running 368.39, optimal power in power management mode. I've also tried prefer maximum performance, but then my card just idles at 1607 instead of downclocking to 253 when idle.
