I´ve bought from a friend an old Alienware laptop, that he bought in USA when was travelling , the Alienware 18, that came with GTX 765m SLI and i7 4700mq. It is working great, but with the GTX 765m sli... Discovered that the Aw18 could receive upgrade of the gpu to the GTX 9xxm, series with native drivers from Nvidia, without having to moddified the drivers, only needing to update the Laptop Bios. (wich I have done already, to the A12, and then flashed the A12 unlocked too.I live in Brazil, and here we don´t have access to the MXM gpus. Very rare here.To play some newer games, decided to find a single GTX 980m mxm, beacuse sli is dead, and in newer games, only one of my 765m works, and it gives me very low fps.Only place I could find one was in Aliexpress. Bought the Gtx 980m 8gb. Along with the 100w heatsink too.Received the gpu, Uinstalled my old ones and installed the gtx 980m. I´m in UEFI mode. In, bios, it shows the nvidia card, no problem.First boot with windows 10, windows install his drivers, one from March, 2018. Asks to reboot, then my problems started...It gives me pink strippes all over the screen.Only way to bot in windows 10 normally, its to boot in safe mode, and then, remove any driver with DDU.2 or 3 times, I could boot normally in windows 10. Updated the drivers for the last ones, december 2020. Gone to Gpuz to make things are ok, runned the pci express bus test. some times it works, some the screen freezed..Tried a lot of different drivers, 2018, 2019 and 2020 drivers.Same problem.One time, I could run Starcraft 2 and Bf4, when the laptop didn't hanged, but now I cant even do that. Made a fresh install of windows 10, but same thing happens...I have the laptop video settings in SG mode now, but did everything from the fresh install of windows 10 with laptop ins PGE (discrete).When the laptop worked for some minutes, I could see that in SG mode, the GPU and Memory clock of the 980m were stuck in 405mhz. When changed to PGE in Bios, then the clock raised up. But, now, I can`t make any driver work...Am I missing something here?Can anybody give me some advice on that?
About 15 days trying to figure that out....
Maybe different Vbios for it, could resolve this problem..
