You are mistaken. I have a single GPU -> 675m (wished I had SLI) I have tried lots and lots of drivers and all failed, giving me a black screen eventually. (I always mod the driver - by saying mod I am adding my SUBSYS_048F to make the driver recognize my GPU for an installation.) Most people on a conversation I read in the Alienware Club @ Dell Forums said they eventually after trying everything with Nvdia Inspector and other fixes they decided to buy a new card as GTX 675m proved to be a faulty GPU. One thing I can tell you since I am not a tech , as a single user my computer Never Gets a Black Screen while not plugged. I do own a 330watt official Dell Adapter. Thanks for your time. If you want to help these 2 links will prove so useful because I posted so much info there. (BSOD nvlddmkm.sys Bugcheck code: 0x116 - Windows 7 Help Forums) mostly this one since its the latest use nvidia as the second source of info.

Hello and sorry for posting this here. Since I cant open a new thread. I am not an advanced Pc Tech , I am just a simple user with a huge issue. Which means I cant provide any useful tips to help so I can never reach 5 posts with the current policy and my lack of knowledge. About my issue. I own an Alienware m18x R1 and I too want to upgrade to a GTX 780m. but first I want to ask everyone who knows and has the time to help to view these links, understand my issue and help me if its possible providing a solution. Black Screens , Insufficient Voltage Resets and all that stuff! | NotebookReview That link above has the 2 links that sum up my problem. Thanks for understanding and for your time.

BSOD nvlddmkm.sys Bugcheck code: 0x116 - Windows 7 Help Forums https://forums.geforce.com/default/topic/830653/pc-components/alienware-m18x-tdr_errors-/1/ These 2 links describe my issue. On Seven Forums you can find my PC Spec. I am looking for someone who can help after reading these conversations or suggest about an upgrade or anything useful. Thanks In Advance. The Issue with the black screens occurs till today.

I suggest you stay with what ever Windows version you have 7 or 8. Windows 10 are still in progress no wonder why they dont support your GPU. Dont be rash to update to 10.

Hello everyone, I am new here, I have been reffered to this site from Nvidia Geforce Forums. I own an Alienware m18x (R1) I use ( ) because it has been modded a lot and not from me so it hasnt any similarity to a true R1. The sad part is that after one year of mid-use my computer started black screens and stuff. We (me and my tech) believe that its a burned GPU / Problematic One. (I have currently Nvidia Geforce GTX 675m installed). I want everyone who knows and can help me to tell me which card can my machine support, for an upgrade. I am currently aware of that video so no I am not looking for that upgrade.I am currently looking forward to change my card to Nvidia Geforce 880m and I want to know if my system can support that upgrade. My Mobile PCI Express Module is MXM 3 I have a 330 watt power supply for my Laptop. My Processor is ARK | Intel® Core I also have 2x 4GB DDR3 Memory Sticks and 2x2 2GB DDR3 currently 12 GM RAM installed. Here are some photos of my card. http://imagizer.imageshack.us/a/img909/6463/gqpOAb.jpg http://imagizer.imageshack.us/a/img661/6049/EvRN04.jpg and motherboard. http://imagizer.imageshack.us/a/img537/5376/LFdJp9.jpg http://imagizer.imageshack.us/a/img540/6320/nPg4gB.jpg http://imagizer.imageshack.us/a/img538/1529/8x95fw.jpg I am expecting for answers that can have a huge posibility of success 95%, I dont want to burn my machine,niether buy a card that cant be used. I am willing to give more info about everything that is needed, BIOS version details about each part watt-volt usage etc. Suggestions are also welcome. Thanks for your time.
