I'm a french and my english is bad ^^ Here I am addressing all the owners of the gtx 780m , I just buy me this card very recently in place of the original 770m I upgrade my laptop "GT70 - 20c 430fr" each restart my pc , I have a 20% loss on the GPU throttling problem ; forced reinstalled every time the driver, I tried with different drivers 331.65 , 331.82 and 331.91 beta to enjoy the power graphic card ... I have no idea what I could do each restart, reset with a loss of power gpu, it's not good for me to reinstall the drivers (any ) every time I restart the pc do 3 tests to be on : I noticed that reboot: voltage : see 0900 0925 max cpu throttling : 570mhz and resettlement pilot voltage : 1.000V 711mhz cpu throttling So big problem of voltage, how to fix it ? , and I have a big instability on the oc exceeding 50MHz on the GPU I have a 180w power supply , is what is missing ? NOS should not help me to boost my gpu ? Or is that flashing the vbios msi installation problem ? VGA Bios Collection: MSI GTX 780M 4096 MB | techPowerUp Help me please !!! thx
