    Hey guys what's happening? It's been a while since I was last hanging around these parts. Recently I got a deal on a GTX 780M so I took the plunge and got it. I've been trying to get it to work and come into some issues. I came from a stock 7970M so the heatsink is made for that card.

    Maybe you guys can help me out?

    This is the thermal paste layout I'm using based on the reference picture by Eurocom. Note that for the two blocks up top I have to stack 2 1mm pads together, it doesnt seem to make contact otherwise.

    Here you can see the amount of paste I put in and the make shift pad for the stack of RAM underneath since I don't have that specific nvidia x-bracket for it.

    Right now I'm running in Optimus mode and through GPU-Z I can see that the 780M chip is idling at 56*c. If I attempt to run a game or switch to dedicated mode the screen will start to show artifact and then freeze.

    So yeah right now I'm quite lost on what to do. The fan doesn't seem to kick in. Should I try to unlocked vBIOS or M17x R4's unlocked BIOS? Do I have to disable onboard sound like on M17x R3? Any help at all is really appreciated!

    thanks for the quick reply j95! I removed the extra layers of pad according to your layout and then instead stack it up for the vertical line of ram on the back of the card. I can boot into windows and tried Max Payne 3 now. My card is idling around 53-54 and 58-61 while under load.

    Is that normal? Should I do anything to check if the ram chips are not getting too hot?

    Say with most thing normal now do I still need to try the unlocked BIOS? It is better to use the unlocked vBIOS by Slv7 right?

    i flashed svl7's vBIOS. However I'm still having trouble keeping the temperature down. The core seems to be stable anywhere from 54 to 58*C but mostly 55-56*C and get up to 66*C while running games but the multimedia buttons on the right of the power button is very warm. It's like the fan won't run until it get very hot or something.

    I'm using HWinfo fan control custom auto settings for now to help with the fan while figuring the rest out.

    It probably would not hurt to obtain the correct NVIDIA 100W heat sink and support plate. The parts for 680M should work perfectly. That should not affect your fan. Those temps are fine.

    Thanks brother Fox, I hear you loud and clear. Unfortunately right now I am not in the States and therefore it would be quite troublesome to get the backplate. But yeah sooner or later I will have to get one.

    Thanks, I copied the settings there from your image and its stable now at 53*C. Right now the GPU chip seems to be fine while the RAM chips or the grey blocks get hot and overwhelm the rest. I used to have a bunch of extra pads, paste and the cleaning alcohol but not anymore :(

    so I managed to get a few some more thermal pads and proceed to put them in. Now if I run in dedicated mode (FN+F7) it will take about 15 seconds before the alienware logo show up (fastboot) and launching a game will lead to artifact and freeze within seconds. Did I just break the card?

    Oh, you are running Secure Boot? If so, that may explain a lot. You might be encountering issues with a vBIOS that does not work for Secure Boot/Fast Boot. Disable those and switch to Legacy mode in the BIOS and it may resolve your issues. Additionally, having Secure Boot enabled may also be interfering with your modded driver installation.
