    Hey guys,
    For those looking to overclock their gpu in a GE60/70 beyond the 135Mhz core limit, finding a clear solution online can be a bit difficult. There's mixed information all over, so I'm hoping this will help anyone who's struggling.

    All of this is based on an MSI GE60 2OD with GTX 760m. I assume given commonalities in manufacturing/motherboard, this would also apply to other 2Ox models such as the GE70 with GTX 765m. The misconception is that these models have their vbios embedded in the system bios. I have found this to be untrue. I used nvflash to create a backup successfully of my vbios. I played around with it using the Kepler vbios tweaker to increase clocks and tried to flash it via nvflash in windows. This messed things up for some reason and I'm not sure exactly what went wrong. I kept trying to use different versions of nvflash but kept getting the same message "NO Nvidia display adapters found". Device manager listed error code 43 beside the GTX 760m and esentially turned it off completely so I could not use it for 3D applications. I was sure I was doomed.

    Next step was - assuming the vbios was embedded in the system bios- to download and flash the latest system bios version. This did nothing. Getting more and more upset, I decided to use the pheonix bios extractor to take a look at the system bios and see what was going on. Low and behold, there's no vga bios in there!

    So, back to nvflash, I now tried booting the dos version and bingo! Using the command "nvlfash --list" it was able to find my GTX 760m. I then flashed it with my backup vbios and sure enough I was back in business. So for anyone looking to overclock the gpu in one of these machines, despite embedding the gpu on the motherboard, MSI has done us a solid and separated the vbios from the system bios. It works just like a machine with a seperate MXM card. Thus, based on my experience you must use nvflash in DOS mode and can use the Kepler vbios tweaker to modify your vbios. You can adjust clock speeds and even the core voltage too! Currently running 1032Mhz core at 1012mv. Max temp 71C under full load. MSI afterburner can then be used afterward for further overclocking if desired.
