MP 7,1 Mac Pro with a Nvidia RTX 2080 Ti

[nikster0029]

I've installed two RTX2080Tis. Unfortunately these gpus inside a standard pc case run cooler, about 10° Celsius less. The Mac Pro 7.1 cooling system is not designed for axial or blower fans. Also on Bootcamp the 3 Mac fans on the front aren't accessible, we can't tweak the speed. I have to use Msi Afterburner to adjust the RTX fans speed but it's not enough, there isn't enough air to push into the blowers.

Whats your best recommendation so far with a setup like this? Stick with one 2080 TI? Or maybe a triple blower system like an EVGA?

AMD or Nvidia gpus with double or triple axial fans push the air inside the enclosure, it stays there, the three Mac Pro fans aren't capable to push the hot air outside the case because they are designed for passive MPX modules. For example on Windows + Bootcamp there is no way to adjust the Mac Pro fans speed, they don't work well if you add not official supported gpus, for example the middle fan doesn't work well because the first one is dedicated to the cpu, the third to the MPX module. I suggest to use only gpus with blower fans and tweak their speed with MSI Afterburner utility. Also on MacOS the AMD gpus with active axial fans need more air volume.

I just got my EVGA ftw3 2080 ti today and did a few tests and its the same thing, I don't get any panics on shutdown or at sleep. The Mac largely ignores it and on the PCIe configurator just shows it as unknown.

This is the ftw3 card that I have https://www.evga.com/products/product.aspx?pn=11G-P4-2487-KR

I just had the chance to try exactly this card in my Mac Pro 7.1. Unfortunately with kernel panic after wake-up from sleep in macOS. Looks like @TrevorR90 had more luck with it.

First post. Not sure if this helps, or is the solution, just thinking out loud...

Sunday 26 April. I installed a 2080ti in Slot 3 of my Mac Pro (7,1) Everything went in fine, Windows drivers are great. No wrong slot alerts in MacOS. Only pain is the lack of Displayport cables at my house, but USB-C works a charm for one monitor. AMD for the second.

Since I'm working from home, computer is in my guest room. Also, I snore, so I sleep n the guest room a lot.

Two nights ago, the Mac woke me up four times (that I remember) with random reboots. Kinda kicking myself for reactivating the Boot Chime. The next morning, I checked the logs, nothing. Stumped. During the day if I walked away from the computer the computer going to sleep meant shutdown. More stumped.

Yesterday after a couple sleep/shut-downs, I went in the Energy settings. Checked "Prevent computer from sleeping..." Since then, no shut-downs and no middle of the night random reboots.

Serenity, for now.

the best option is to install Pro Render or make the Windows 10 partition and use internal or external Nvidia gpus.

AMD Radeon™ ProRender

AMD Radeon™ ProRender is a powerful rendering engine that enables creative professionals to produce stunningly photorealistic images.

ProRender is unfortunately a horrible useless mess and not a production ready replacement for gpu rendering. At least, in C4D. I've yet to see any report of ProRender having benefits over Redshift or Octane on any system.

Has anyone installed a 2080ti in slot 5 with two MPX modules below in slot 1 & 3? Is there enough room to keep the card cool enough?

That sounds expensive.

That sounds expensive.

Trying to turn the Mac Pro 7.1 into a viable gaming machine is quite expensive.

Does anyone get random shut downs using Premiere Pro? I've installed a 2080 TI and while everything runs great 99% of the time, I get kernel panics in Premiere Pro 2020 at random times. It seems to be when PP wants all 32-threads to itself and is loading in proxies/sequences — as that's the only time I've experienced it — but I can't be certain.

I've had the VII in prior — with the 580X initially — and never experienced anything like that.

My current setup is:

16-Core
96GB RAM
2080 TI (Slot 5)
Radeon VII (Slot 3)
W5700X MPX (Slot 1)

That is one full tower! You might have some cooling issues there. Have you tried taking out the other GPUs to see if that helps?

I haven't had the time yet, but intend to do some QAing later today. What confuses me is that I can stress test this setup in other ways and run into no issues.

For instance I can export 250-images from Lightroom that are 100MP large — no sweat. I can export a 5-minute 5.5K clip from FCPX (with grading) and the system chugs along.

By all accounts it's just Premiere Pro that is giving me an issue. I've moved a ton of my work off of the program, so it's not a massive heartbreak, but for the few projects I still have to touch it's a bit annoying.
