I am trying to overclock my 970m (yes it's properly cooled and repasted etc). I used to run the core at 135MHz + with no trouble. Lately I found my memory slider wasn't holding clocks so I asked SVET (MSI forums) to unlock my VBIOS and he gave it a mild gpu core overclock. But the overclock won't boost. The core clock stays the same stock 1038 limited by drivers.. The only way this works is when I install new drivers and don't reboot. after the reboot it will be hard capped again. does anyone have any clue?
