Clevo P750ZM: GTX 980M Overclocking Investigated

We posted our full review of the Eurocom P5 Pro (Clevo P750ZM) last week and mentioned that we were investigating overclocking potential. Armed with an updated VBIOS and running NVIDIA’s older 344.75 drivers (as the current NVIDIA drivers lock out overclocking), just how far can you push the GTX 980M? We’ve run some additional tests to find out how much headroom exists and what happens to thermals in the process.
