Nvidia Geforce 650m driver problem for windows 8.1 on macbook pro

I installed the drivers from System requirements to install Windows on your Mac via Boot Camp - Apple Support this link. Now I got access to my wireless internet (so thank you!!!). I finally see Nvidia GeForce GT 650M in the Display Manager (thank you AGAIN!!!) and in "Other Devices" is only something named SMS.

I am oh so very grateful. I don't know if my Sims will work, though, but since I can find my Nvidia I Think it should. Do you Think I should download and run the Nvidia-drivers from their website though? Or I don't have to do that now?

Thank you again!!! You too, DemetriAA! 🙂

Ps. My text are still very small on Explorer and sometimes in apps etc, but I could adjust that in the Control Panel, right?

You can change Font and DPI in the Display and Resolutions. I would not recommend nVidia drivers yet. Please test with the BC drivers that you currently have. If you run into any issues, then you should try the Game Ready drivers for the 650M. Apple mostly uses the M(obility) drivers in most of their Macs. The new MacPro (and older MPs) and some iMacs may use different GPUs.

Please test your audio.

Okay, thanks! I will wait with the Nvidia-drivers then.
I tried the game and it's still dark and lagging ALOT, but I'm working on it. Some guys from the Sims-forum is trying to help me make the game recognize the graphic card.
You have been very helpful and I am most grateful. I have struggled for 3 days with getting internet to Windows and I have been scared that something is seriously wrong when I couldn't find the graphic card in Display Adapter. But now I do 🙂
Thanks and have a great weekend!

Thanks for your infor, may be I will have to use method 1 to check the Headset sound.

Installing nVidia 306.37 from Bootcamp 5.0.5033 package partially worked. After doing it, I could finally see the interface (no blank display), nVidia settings show opens and looks ok, but there's some very ugly color banding going on. I can see it on the windows 8.1 start screen, the gradient backgrounds are not smooth. I can see the same on 3DS Max viewport. The background should be a very smooth grey to black gradient, but shows these steps, also known as banding.

I'm still in search for the right driver. The one in bootcamp 5.1.5621 doesn't really work. Blank screen, always.

This a mid 2012 15" Macbook Pro, non-retina, with a 650m.

Any suggestion?

Thanks

Do you want to consider trying these?

Still having banding issues, which I don't have on OSX. I think it may be related to the actual display (screen) drive (not the graphics card driver). When I try to install AppleDisplayInstaller64, it gives me a "this program might not have installed correctly" message. Regardless of what I try, Device Manager always shows a Generic PNP Monitor. Any Idea about this?

Regarding the blank screen issue, these are the ones that worked forme:

306.37 (from Bootcamp 5.0.5033)

306.97 (from nvidia site, windows vista 64 bit page)

310.90 (from nvidia site, windows vista 64 bit page)

The following gave me a blank screen:

307.83, 344.48, 347.09, 347.25, 347.52, 350.12 and the one that comes with BootCamp 5.1.5621.

I stopped testing driver versions.

Had the exact same issue on my mid-2012 pro retina model.

If I installed it on a MBR disk instead of a GPT+EFI disk, it did work though because only the nVidia GPU is exposed then by the "BIOS".

Even with the latest nvidia drivers ... no problem

I used wintousb to install win8.1 on an external USB3 SSD. Works smooth!

So just to clear things up, guys:

Currently there is NO way a 2012 nvidia 650m macbook pro will work 100% FINE with windows 8.1 via UEFI, correct? Only MBR?

Yes, that is correct. If you are adventurous, you can try editing the PCI registers, to make the EFI expose it correctly.

It maybe an issue with the discrete GPU. I had the same issues with bootcamp and eventually gave up. After 10.10.3, I started seeing GPU panics running Chrome and Lightroom. I used a tool called gfxCardStatus (http://gfx.io), which notifies you when you the GPU switches. Basically, whenever it switched to the discrete GPU, it curtained about 2 minutes afterwards. The good news for me was that this is a hardware issue and Apple will fix it free of charge:

The repaid would have cost $540 normally, but it's being covered. My MBPr is beyond AppleCare and the repair was still free. I'd highly recommend bring it in to have it looked at. So far, no more GPU Panics.

So even after the hardware fix, I still had issues with Bootcamp. I have been trying to avoid the EFI method since most everything doesn't work after you install the Bootcamp Drivers. When using Bootcamp and using the BIOS emulation mode (i.e. Windows as opposed to EFI Boot), I'd always end up with a blank screen or the ever so helpful "no bootable devices" message. Selecting EFI Boot would get the installer to work, but everything goes south once the Bootcamp drivers are installed. You have a working GUI, and then the screen goes blank and there's no way to get it back.

After some digging, I found this StackExchange post describing a method using VirtualBox to install Windows:

http://apple.stackexchange.com/questions/179486/boot-camp-install-of-windows-7-i ssue-no-bootable-devices/180263#180263

The short version, everything now works. My hardware is a MacBook Pro Retina, Mid 2012 (MacBookPro10,1) and I've had the logic board replaced as part the video recall (http://www.apple.com/support/macbookpro-videoissues/). I am running Windows 8.1 with Bootcamp Driver version 5.1.5621 and everything is working great. I have sound, a working video drivers, bluetooth, etc. and I didn't have to do anything to disable one of the two video cards. If you go this route, make sure you do the MBR stuff as described in step 6. This works and seems less complicated than doing something like rEFIt or something.

Ryan-

A Windows install via UEFI on a mid-2012 MacBook Pro isn't going to work. I have tried multiple times and it always ended up with a blank screen. Even if you could get it work, you'd have no sound. The legacy BIOS method is the way to go. See my last message in this thread with the VirtualBox install method. Slightly convoluted, but it works.

Hate so much this problem 😟

Wanted to play a old game I used to (Warcraft 3) and can't get it working. Same black screen when installing nVidia drivers.

A 2010 Mac is a preUEFI Mac. Can you run msinfo32 and check the BIOS mode value? What is the current version of the nVidia driver?
