    Taken directly from the Prema Mod site:
    • Power throttle disabled for good
    • Over-voltage slider enabled and adjusted (up to the maximum of 1.2v)
    • Activated and adjusted thermal slider (to keep it cooler if desired)
    • Core overclock slider raised
    • Fixed 3D voltage base-line in order to stabilize OCs (based on average ASIC)
    • Thermal protection @ 92c (once 91c are breached the system throttles volts and clocks in order to protect it)
    • Protection against Furmark and Kombustor GPU burnout (AVOID those software even with stock vBIOS)!
    These vBIOS use stock clocks and voltage and also keep the stock Turbo functionality intact (minus the throttle) unless, You decide to overclock/overvolt.

    Try running GPU-Z rendger test in the background without disabling the GPU in Device Manager. Then launch a second instance of GPU-Z and see if it works while the render test is running. It may be losing sight of the GPU due to interference from the Intel HD Graphics.

    Use an older driver for flashing...the newer ones may break nvflash on Optimus systems.

    @newlich - Try like 362.00. That will probably work OK.

    Installed driver 362.00. Run two GPU-Z, one with render test, another one without. Still failed to flash Prema vBios.
