I've recently installed a new PSU in my computer in the event that I want to add another GPU in the future. However, for the time being, i've used the extra watts to try and overclock my computer. I've successfully enabled XMP and enhanced turbo in the bios, however, when using the MSI OC scanner tool in afterburner, my games become unstable (overwatch looks like its suffering low FPS even though the counter is at a consistent 155) and crash. My GPU also gets a tad hot (it peaked at 89°C). The PC is situated in a room with a cool ambient temperature, and airflow is fine (there's a case fan at the top-back of the pc which blows out hot air, and the bottom of the case has cool air intake.
