Hi everyone I have a Clevo P170EM with a GTX680M. I have flashed the 80.33.0.10 vbios with stock voltage. I use MSI afterburner to overclock the card but I am not sure what are the admissible values for an onverclock for core and mem. I set them to +250 and +500 (~1005/2400), are these ok? When I use these values after a while gaming I hit 90ºC temp and the card down clocks to 324 MHz and it doesn't recover unless I reboot is this normal? This down clocking also happens if I set values like +250 and +400 core and mem. Onec again is it normal? Can anyone tell me a decent value set that is stable and maximizes the performance I can get? Thank you so much in advance.
