AMD Radeon Pro W5700X & AMD Radeon Pro Vega II in 2019 Mac Pro

Hello,

I have a AMD Radeon Pro W5700X installed in my 2019 Mac Pro and just installed a AMD Radeon Pro Vega II with it. I've don't a benchmark and not seeing any real difference in performance. I also noticed that the "About this Mac" only shows the W5700X.

Does it matter which module is in slot one?

I have 3 monitors connected, should I spread them out between the two modules? Nothing special about the monitors.

Thank you for the replies in advance.

Dear CaliPvp,

Check out this article that Apple made regarding PCI cards.

https://support.apple.com/en-us/HT210104

Make sure to follow the installation instructions or check out this video from Apple Support on how to install a GPU:

Maybe take out your GPU (by following the steps Apple provides) and reinstall it?

Hope it helps :)

Dear Calipvp,

You stated that if you go to About this Mac > PCI cards, your GPU didn’t show. That was why my advise was to reinstall it physically just in case.

I would otherwise have no clue why the GPU shouldn’t show up in there.

Apple Support (download the Apple Support app from the App Store) might be able to help you out beter on this one since they could look at your Mac remotely and find out why it is not showing up in the About this Mac section.

Hope this one helps :)

"I also noticed that the "About this Mac" only shows the W5700X" is what I said.

If I goto the "PCI Cards" I can see both cards, but that is not what I was asking.

I was asking the following. Not sure why that part doesn't show up for you in my original comment.

Does it matter which module is in slot one?

I have 3 monitors connected, should I spread them out between the two modules? Nothing special about the monitors.

Hello ABoksan,

Thank you for replying to my post. That was not helpful. I don't have a problem installing the module.
