MS-GT780/783(17''): .30H MSI GT783 Unlocked.zip MS-1761(17''): 3.06 MSI MS-1761 Unlocked.zip The above two BIOS should be the same right? Also, I have GT780DX. After I flash the ".30H MSI GT783 Unlocked.zip", I still cannot change turbo core ratio. I change TDP limit as well as different core ratio under BIOS save and restart. It will boot into windows without problem, but I see no change for any turbo ratio. PS: I have i7-2920XM, so it should be able to let me increase the clock ratio. Anyone have some thought or advise? I have also tried ThrottleStop with the same core ration setting, no success as well, and I found out that ThrottleStop won't allow me to change the Power limit in its option.
