Many midrange GPUs from older generations don't end up power-limited even at stock because of how the voltage/frequency curve is set. The good news is that unlike newer NV GPUs, Maxwell doesn't have the voltage locked across the board however some individual GPU models allow upward adjustment and some don't. You seem to have thermal headroom so if overvolt away if Afterburner supports it on your card.Hi! Taco downloaded msi afterburner last night and just finished the test. My methology was this:
Test with everything default. Boost 1380
Test with everything default, fan 100%. Boost 1380, but temperatures a little lower. you cn see second part where fan ramped to 100%...

Thn I installed afterburner nd set full power limit to 115%. Nd same 100% fan. Boost 1380. Taco guess it's what this particular chip is binned for somehow? Nt sure...hmm.
