@joevt Terminal was able to produce Thunderbolt but errored out on Graphics/Displays. A chain of 3 worked too. I placed the Radeon VII at the end of the chain and OpenCL performance saw little loss. Everything worked fine and stable. Here are some screen caps.

Nice findings. So I went a different route for my production GPU needs a long time ago, but I still have a 6,1 and a 2012 Mac Mini sitting on my desk.  I can snag a cheap Razer Core v1 (TI82) and the Purge Wrangler script will enable it now?  Time to check Craigslist.

Hello. I just hooked up my 2018 Mac Mini to a Razer Core X Chrome with a Radeon VII and I am having the "fans during sleep" problem. Do you know how to fix this issue?

@jltawil

what adrenalin software are you running? you should be running the direct download from AMD and not the bootcamp drivers.

This is in Mac OS X Mojave 10.14.6 I am not running windows on the machine other than a VMWARE W10 clone for menial tasks. After reading about everyone's woes with the R7 I've pretty much given up...

It’s an OS X thing. Someone explained that it sleeps (the machine) but forgets to tell the eGPU to sleep so the fans go all on.

@flint-ironstag Yes the Purge-Wrangler script handles both TI82 controller patching and eGPU on Thunderbolt 2. It's a very smooth and quick process thanks to the continuous improvements @mac_editor has done. It's down to choosing a GPU that fits the Razer Core V1 power envelope.

@jltawil The Radeon VII wasn't optimized by AMD for eGPU use. Its firmware is missing the ability to detect the enclosure USB-C controller power state. Without this functional communication the enclosure would go to sleep and cut off power to the slot but the Radeon VII has no idea then runs its fans full blast. There are some variations of sleep mode in different Thunderbolt 3 enclosures. To date I only found the NetStor HL23T-Plus to be the one with proper sleep mode for the Radeon VII.

Shutdown from Win10 doesn't have the issue... Shutdown and Sleep in Mac OS does still. I love my Radeon VII but I wish I had spent the extra cash to go to Nvidia's 2080 Ti... but that is for another day.

I ended up returning the Radeon VII back to the retailer. I already own the Razer Chroma X and I really did not want to deal with having to return that and get a different enclosure. I ended up ordering a PowerColor Radeon RX VEGA 64 to go with my Mac Mini.

So my next question is this - how do we output to the Ultrafine 4k Displays with the EGPU?

I am fairly new to using FCPX (early this year).  I recently bought Radeon 7 with Razer Core X Chroma to boost FCPX with my iMac i7-7700k 64GB.  I need more GPU horespower to smoothly use 4k editing with avg. of 6+ effects.  I am using latest Catalina and 10.4.7 FCPX.  I am not clear on what the issue Radeon 7 is with eGPUs you speak about.  Sounds like eGPU goes into sleep mode cutting power to Radeon 7 but somehow fans still blowing full power?

I looked at many of your posts regarding multiple eGPU use, Radeon 7 etc.  I am with the understanding that more than 1 eGPU will not work with FCPX but it appears using your Nestor eGPU you are able to get 4 eGPUs working.  Maybe I am wrong in my observation but if this is true I would love to know how I can do the same and get FCPX to use both internal and multiple eGPUs for more graphics power.

I am willing to to look at acquiring a 2013 Mac Pro or recent Mac Mini to accomplish this.  I am not an expert or have deep knowledge with eGPUs but if there is a way to get FCPX to use multiple graphics cards including multiple eGPUs I would love to know how to do it.

Is that possible?  If so, how does one go about doing it and what hardware etc. is needed to pull this off?

I cant say I have experienced the sleep issue with Radeon 7 eGPU mix yet, but I have only done one overnight render on a 200GB project and I will say something wasn't right with it.  It seemed it stopped rendering at some point overnight and only when I woke up the iMac display did it continue rendering.  Is this the issue you speak about or is it something else altogether?

Love to hear your input as I am very interested in your work with eGPUs and want to know if anything can be done to meet my needs/goals for FCPX and multiple eGPUs.

Thanks
