@itsage, So what should I do in your opinion? I've got these egpu's but I can't use both of them to at the same time. Should I buy a different computer or buy a motherboard with tb3 that I could plug them into and make a rig that supports egpu's? If so what should I look for? Also am I SOL in regards to trying to get 2 egpu running on my mac then?

@jdouxby, macOS can handle 4 supported AMD eGPUs. Boot Camp has always been a challenge so you would have to experiment with different workarounds. It's not straight-forward to set up multiple Thunderbolt eGPUs in Windows in general, so I'd recommend using desktop if you need multi-GPU for mining.

@itsage, so should I use a different os on a desktop or would windows work well with egpu's on a desktop rather than mac bootcamp? Sorry I'm a noob just trying to comprehend this stuff. Also would I need to like buy a tb3 motherboard or prebuild or could I like use an adapter to connect my egpus to the motherboard?

@itsage I wasn’t really using my Mac with iPhone to begin with. You add music, movies, etc to your phone pretty easily without iTunes (RIP on MacOS, lol), that is, if you’re not using Spotify or pandora. Apps like Adobe acrobat and the Aloha browser can handle most file types and transfers from a PC (using the windows version of iTunes) or the internet. iCloud.com on any browser on any device can be used to locate your phone, assuming you enable that feature. I basically use my phone as an entirely separate computing device, since there’s a an app for just about everything. Smile

@jdouxby @itsage I finally found a reasonably priced 2018 i3 Mac Mini to play around with. I'm able to connect my 3090 and 2070 to the Mac Mini, but my Radon VII (in the Core X) doesn't want to seem to work because of error 12. I tried using a different TB3 port (hopefully on it's own TB3 bus/controller), but no success.  I tried disabling the PCIe access to a bunch of things (ethernet, sound, etc), but to no avail.  I wonder if another nvidia GPU might work, but I don't have another eGPU enclosure to test that out.

@dregpu, I've personally have not been able to get more than 2 Thunderbolt eGPUs working in Boot Camp. You may want to try Linux or HiveOS on an external drive to see if that would work better.

I left it running for 24 hours to stress test the setup. Earning average was $28.14 per day with an accepted speed of 302.1454 MH/s through Nicehash. Power consumption was 22.31 KWH through Kill A Watt meter. Energy cost in my area is $0.1146 per KWH so the setup costed $2.56 per day.

Wow, that's a pretty cool setup! I have a few questions about my new build and you seem like the perfect person to ask! 

It's taken me a few years to save for this and would hate for things to not work so any advice would be greatly appreciated!i

Im currently looking at getting a Zotac 3090 and Gigabyte GA-Z590 Vision motherboard which has 2x Thunderbolt 4 connectors. Do you think I would be able to plug and play 2x Aorus 3090 eGPU purely for mining? I'm not very literate with computer parts so I'm really hoping I could just plug and play lol

 

Cheers,

@alex_pan, Getting more than one eGPU to work on a host system with dGPU/s is typically not plug-and-play. I have a few Gigabyte Vision D motherboards (Z490, B550, and Z590i). There are some workarounds but it's not the same on all systems. For my Z490 motherboard, I could only get  one eGPU to work (3x dGPU). For the B550, I had to enable [Above 4G Decoding] and increase [Prefetch Memory Allocation per port] to 512MB in order to resolve error 12 on AMD eGPU. You will have to experiment with your own setup unfortunately.

@itsage, So would it be correct to assume using just one eGPU with 2 dGPU would be plug and play?
