For instance, I just turned off my all core OC and went with stock MSI game boost, which is a much less aggressive OC @ 4.2ghz all core and it hit 81c running Cinibench R20. With my settings it hit 77c (these are updated from last time as I was only running at 4.33) max after hammering it for 45 min. I ran it twice with MSIs settings and hit 82c.
