24.7 mhash heavily overclocked to +1000 memory through MSI Afterburner program, power limit to 75% , temp limit 71 grade celsius, core clock +65 . That is the max I have reached from this card. It is not always stable and sometimes hash rate drop to 20.8 mhash for a few seconds than it goes back up to 24.5-24.7 mhash. It also depends on your hardware too, when I tried this in Windows 7 with LGA 1150 dual core processor it reached 22.9-23.2 mhash max. When I tried in Windows 10 with all the updates until now with LGA 1150 corei3 processor I managed to get the 24.5-24.7 mhash.
