SUCCESSFUL Yosemite Install with ASUS GTX 750 Ti - but with HDMI not working on NVIDIA Web Drivers 3

[fbc]

What I can't seem to work are the DVI ports. VGA port is always taken as primary no matter what I do. If anyone knows how to tell the card to take the DVI as primary, let me know. Thanks.

I just want to thank you squidlr for this CUDA tip. I have an ASUS flashed with Palit and all I could get to work was the DVI port. Now I am rocking three monitors because of your tip.

Good man there, good man.

I had a go with my dual fan 750ti and installing only the Cuda drivers. It worked outputting HDMI but it seems that it was running under super low quality with bad resolution and glitchy animations and no transparency. I took a look into the CUDA panel in settings, it appeared that it wasn't detecting the card.

For some reason I am forced to use NVIDIA web drivers unless my card is not detected.

I am currently running on VGA only with full resolution and transparency by using CUDA drivers and Web Drivers.

I had a go using both drivers and disabling the injection but it doesn't seem to display.

If anyone is still having problems after attempting to flash the palit rom or is unable to find/flash the rom here is a bios that worked for me BEAUTIFULLY for DVI. I only have 1 monitor so i have not been able to test with more than that. Here is everything that I used to flash the bios called (750ti.rom), including a backup of the Asus bios called (old.rom) incase there are problems. If you have more than 1 monitor I can not guarantee anything but I hope it works for you. Check up in another forum how to flash the Rom using nvflash. Have fun hackintoshing.

Hi, do you know where i can find unibeast for elcapitan 10.11.6

 

[mohammedamr]

DVI. I only have 1 monitor

Hello,but do you get a startup screen when booting up.

I flashed Palit GTX 750 Ti

Hi,how did you flashed and did you get the booting screen after flashing.

I confirm that My asus gtx750 oc (not the Ti edition ) has now the hdmi port working in el capitan after the palit firmware flash founded At www.techpowerup.com (palit gtx750 )

Yes!
Work! No problem, no lag!
OS X El Capitan 10.11.1 (Build 15B42) & MS Windows 10 Home x64 HDMI port
Thanks everybody!

I also confirm this. ASUS GeForce GTX 750 (GTX750-PHOC-1GD5). OS X El Capitan 10.11.2

Hi,

I have the same card GTX750-PHOC-2GD5 (NOT the Ti) https://www.techpowerup.com/vgabios/161156/asus-gtx750-2048-140402 and the video that I was getting on Sierra 10.12.5 with latest NVIDIA Web Drivers, SMBIOS 17.1 was distorted and totally unusable.

I flashed the palit rom as you wrote on the thread from this site https://www.techpowerup.com/vgabios/154549/palit-gtx750-1024-140103 as you did.

And I had success, hdmi now works with full acceleration without any problems, but DVI does not! I want to connect two monitors on my machine.

Has anyone connected successfully two monitors with the Palit firmware. I do not get any signal out from the DVI (not even in the BIOS and during the boot-up sequence).

Thanks!

Hi.

I've just built a PC (well, yesterday) with an ASUS gtx 750 ti oc, exactly this one, https://www.asus.com/es/Graphics_Cards/GTX750TIOC2GD5/ and installed yosemite on it.
The only way to get graphics working was flashing another bios, sorry guys, I tried everything but in the end, only flashing worked for me.

I will try to explain the process and make it clear for everyone so you can do it too.

First of all, we need to make a bootable usb drive, with rufus, for example.
https://rufus.akeo.ie/?locale=en_US

This program makes a bootable usb pendrive that boots into pure msdos, so you can use nvflash without problems (I couldn't make it work in windows, so this way is safer and problem free).

Once you have created the bootable usb, download nvflash from here:
http://www.guru3d.com/files-get/nvflash-download,2.html

Uncompress it and copy all the files located inside nvflash folder (not nvwinflash, that one is for windows) to the root of the usb you just created.

Then, download this bios file, the only one that worked for me, I tried another palit version, but this one is the good one.
http://www.insanelymac.com/forum/topic/302628-gtx-750-ti/?p=2099737
Credit goes to ultralaser for the file.
Uncompress the rar file and copy the file gm107.rom to the root of the usb drive.

Reboot and select the usb drive to boot from it.
Select the keyboard mapping that suits your needs.

And here goes the flashing thing.
These are the commands.

nvflash --protectoff
nvflash -4 -5 -6 gm107.rom

The program will ask for confirmations, this is your last chance to abort mission, if you go ahead like I did, it will flash your card bios.
The process will take like a minute or so, you will see the progress as dots on the bottom of the screen.

After flashing has ended, you can boot into mac os using both dvi ports, didn't try hdmi or vga yet, but I can use my two fullhd monitors with acceleration, without problems.

You will need the nvidia web drivers installed on your system and booting with nvda_drv=1 of course.

Hi I followed the information in this post in the previous thread.

I Flashed my GTX750TIOC2GD5 with a gigabyte rom, now when booting up it says "please power down and connect the PCIe power cables for this graphics card"

Will I be able to re flash with a PC that has two PCIe slots? or will that PC not boot either?

EDIT:

I was able to set my BIOS to boot from the on-board Intel Graphics, From there I booted to the DOS flash drive and was able to re-flash the GPU to stock.

Might be useful if someone flash their cards with the wrong rom like I did.

Also I came across this VID that allow you to use your on-board Intel graphics alongside your PCI GPU for dual monitor support without flashing. (I will write the procedure here over the weekend when i have time)

I just plug my HDMI cable back into my 750ti when gaming in windows.

Cheers!
