Hi all, I am a bit confused about what GPU can be used in a Mac 1,1. Based on the sticky, looks like max wattage for the card is 225watt. However, I am seeing report of successful GTX980 in a Mac 1,1. I have a GTX 970 that I purchase and reading online that it uses 300 watt. Is it something that would work or should I get something like a GTX 770 instead?
Got a tip for us?

Hi all, new to me Mac Pro 4,1 flashed to 5,1. I have a EVGA GTX970 (4GB) installed by also have the original Nvidia GeForce GT120 (for installs).
Should I be running my two monitors both from the GTX970 for best performance, or one monitor for each card? They only run 1680x1050 and 1920x1080. I figure both on the GTX970 but I am new to this Mac Pro.
Thanks!

AFAIK, in general, connect both monitors to the 970 is a better choice. Unless your main workflow is to use the 970 to compute. Then let the 970 handle as less monitor as possible, let it only do the compute may be a better choice (depends on the software).
That would explain issues I was having with a 4K HDR monitor/TV with SwitchResX a few weeks ago. Disabling HDR on monitor fixed and worked fine. For current work wasn’t an issue.
If testing HDR video outputs, probably best to stick with an AJA or BLACKMAGIC style card.
Can anyone hlep me... After a four days, I'm unable to get my newly purchased Palit Nvidia 1050ti Kalm X working in my Mac Pro 3,1 2.88Ghz 2008. (this may be slightly overkill, but I bought it now for motion graphics work)
The Nvidia web drivers are installed and do recognise it by name, in the Nvidia Driver preferance pane of 10.13.3.
I installed 10.13.3 on it because pascal cards require 10.12.4 and above.
I am accesing the Mac pro via screenshare over a network cable from a laptop and giving it internet via firewire.
Other things:
I have the card in slot 2 (as i read slot 1 may cause problems?)
The OS is running from an SSD, there is a Usb 3.0+Sata card installed. (tried it with it removed)
Monitors are Apple Cinema Display 20" via DVI and HannsG Hi221 Display Via HDI or VGA)
Any ideas anyone?

That card looks like it was modified from reference design... did anyone report that this card was compatible?
Is your machine still ID'ed as a Mac Pro 3,1?
What OS build number are you using?
Too late to return the card and get a more widely macOS compatible one?
Thanks for the reply.
No it wasn't spoken about annywhere as working. I made a few assUmmmmmmptions.

Yes. I 'tricked' the os into installing by adapting the High Sierra instaler only.

Might be, it's a fannless card I was after though so I'd like to try a little more. But Yes, I'll find out if they will take it back.
To be clear, he said HDR is not supported. SDR 10-bit modes are supported and should be working, right?
Ahh okay, it wasn't clear that the original email was talking about 10-bit SDR. I'm surprised they claim it's not supported, as I've seen many reports of people suggesting it works fine (or that there was an RGB->BGR color swap bug, which was subsequently fixed).
ahh interesting. Does this mean I can also use a mini 6pin to 2x6pin cable to power the 970? or I am just asking for trouble here. If I can do that, then I might be able to also run my old AMD 1200X at the same time.
Depends on your card, it’s hard to tell if don’t know the exact model, or it’s power draw characteristic.
Hi!
So I got a newbie simple question;
If I install a non-flashed graphic card, I will not get a EFI screen! Ok I get that. But, is that just the display of the Startup Manager or...? So my question is: Can I still switch between system (osx and win 10 on different SSD)? I know - can I do it in the "dark" (absensce of the EFI screen, just waiting for let say 90 sec and do a left/right errow and enter)? Change the startup disk blind? I have a "blessed" windows SSD so when I reboot in Windows the OSX fires up automaticly.
Best regards

I have the EVGA GTX 970 SC. A quick google seems to indicate that I am asking for trouble.
https://www.techpowerup.com/reviews/EVGA/GTX_970_SC_ACX_Cooler/23.html
power draw of 188w
Generally, the cards that are closest to “reference” design are the most compatible and cause the least drama. My 980 is an EVGA but is reference-clocked, although I did go with a dual fan model instead of the single blower. It has been rock solid, quiet, and cool since 2016.
99% won’t work, assuming this card has same power draw characteristics as the Gigabyte 970
http://www.tomshardware.co.uk/nvidia-geforce-gtx-980-970-maxwell,review-33038-12.html
Then it will draw >130W from the aux power connectors. If you want to power it by just a single mini 6pin, extremely high chance that your Mac will shut itself down when the GPU is under stress.
Interesting...I have been having the same glitches, suspected it was a driver issue. However, I am running 387.10.10.10.25.261, the latest driver, and am still experiencing the problem.
It only happen in the last 2 web drivers (both are for 10.13.3). And I found that enable “reduce transparency” can avoid it.
Is it possible that changing (flashing) the ID of my MacPro 3,1 (i havn't flashed the card) to 4,1 or 5,1 will help getting a Nvidia Palit 1050ti Kalm X?
OS: 10.13.3 (17D47)
Webdriver: 387.10.10.10.25.156
Or are there other routes I can look at for diagnosis or understanding what "cahnged from the referance design" means that
bsbeamer mentioned?
Thanks for reading.
The latest macOS and latest NVIDIA web driver will have the most compatibility with newer 10XX cards.
With an authentic 3,1 machine I would not have suggested that particular card you purchased. The heatsink alone shows they likely modified it from the reference design. Who knows what else they did that COULD possibly create an issue with the NVIDIA Mac drivers. You likely would have better luck with a card directly sold by NVIDIA. Would suggest finding what GPUs other 3,1 users have that work with your OS. I have never seen that particular 1050ti referenced on these forums.
If you're stuck with Palit, take a look at these first:

http://www.palit.com/palit/vgapro.php?id=2597&lang=en&pn=NE51070015P2-PG411F&tab=sp
This may be the cheapest 10XX card that NVIDIA is currently making and selling:

Like this one?
For anyone that have this issue with the 387 driver.
It's actually OK to downgrade the driver back to 378 to get rid of this bug.
I reported this to Nvidia, but they failed to fix this issue in the latest 387...161 driver.
Rather than wait, I've tested a few methods. Eventually, 2 working options.
1) Safer way. Enable "Reduce transparency" in System preferences -> Accessibility -> Display. I tested this for a few days. Didn't see a single colour bug.
2) Risky way. Disable SIP (I can confirm it's OK to disable SIP with the latest 161 driver installed in 17D102), then run
Code:
bash <(curl -s https://raw.githubusercontent.com/Benjamin-Dobell/nvidia-update/master/nvidia-update.sh)This is risky, because there is no guarantee that any web driver other than the V161 can work in 17D102. However, there are plenty of Hackintosh guys tried it already (because they have lots of issues with the 387 driver, so lots are forced to downgrade to the 378 driver). I also gave it a go, and tested this script and driver. I can confirm that this script and the 378...106 driver both can work on my 5,1 (GTX 1080 Ti, spec as per my signature). I ran few quick tests, no bug / glitches so far. And I disabled reduce transparency, tried lots of Windows movement, scrolling, etc. No colour bug yet.
Apart from that, I also ran few benchmarks, tried some simple video editing / rendering, also no issue. Just like running the 378...104 driver when I was with the 17C205 build.
Despite the info on GitHub says SIP can remain enable. It's not entirely true. You can keep SIP enable to run this script. It can still install the "best" web driver for you, and patch it accordingly. However, the patch will void the NVDAStartupWeb.kext signature. Which means, OS won't load it if SIP is enabled. It's not just theory, but I actually tested it by myself.
I tried to run this script with SIP enable, the cMP will restart into black screen only.
I then update the web driver back to 161, disable SIP, and run the script again. This time the 378 driver can load properly on first restart.
For anyone that require the Mac for working, but face this annoying colour bug, I recommend you simply enable "Reduce Transparency". But if it's just your personal computer, and you know how to recover your computer if the web driver screw up your Mac. You may try this scrip to downgrade the web driver.
At this moment, not sure if this driver downgrade can also fix the possible memory leak in High Sierra (in my case, mainly from Safari and Messages). I will monitor that in the next few days. Hopefully this is a good solution to fix the abnormalities that only exist after upgrade to 10.13.3.
Update 1:
After 2 days of testing, no colour / performance bug. Safari, Messages memory usage back to normal (it seems the memory leak was really web driver's fault, not Apple's fault). However, I realise when the monitor is in standby mode (computer normal idle, not sleeping), if I want to wake up the screen, this force installed 378 driver may need extra 10-15 seconds (never see this with any "correct" web driver). It only happen twice out of more than 10 "wake up" in these 2 days, not too bad, and no other abnormalities after wake up.

Hi hi looking for some clarification. I am currently running El Capitan and understand I need at least 10.12 for the web driver to support my pascal titan x. I was very pleased with the stability of el cap and that I was also able to get the hdmi audio working.
Is there any way to mod a newer version of the web driver to run on this OS?
If not, can anyone comment on the viability of HDMI audio on pascal cards in 10.12+?
Thanks!
