Hardware:
Gigabyte RX Vega 64 was unstable in Akitio Node with original PSU. It appeared the PSU would shutdown spuriously during gaming, maybe due to over current.
Swapping PSU to Corsair SF600 solved stability issue. 

 

OSX10.13.x
Update 10-31-17: Generally works 

 

Windows 10 1709 (Fall Creators Update): - Updated 2017/10/23

Win10 install procedure
- Deleted Bootcamp and recreated under OSX 10.13.1.
   - Required disabling timemachine and deleting localsnapshots to allow bootcamp to partition disk
- Installed Win10 with eGPU disconnected
- Hot plug eGPU, drivers install with Code 12
- Reboot with eGPU connected - hopefully now eGPU comes up and iGPU is disabled

- Windows Boots with eGPU attached - works great
   - Boots from OSX select bootdisk or Cold boot
   - iGPU appears to be disabled.

OSX 10.13 beta6:
Desktop mode work OK.
3D games have sever driver issues:

  • Xplane11 has severe issue with textures not mapping correctly - large solid rectangles of colors
  • Heaven graphics corruption issues
  • Luxmark crash on beta6 (used to work)
  • Steam games: Tomb Raider, Hitman, Verdun; General crash issues

 

Windows 10 1607 (Anniversary Edition):
No boot menu with eGPU plugged in.
Code 12 in Win10 when hot plugging eGPU on Windows logo

Code 12 solved by following the guide by MacFreekDotKext
https://egpu.io/forums/builds/mac-mini-1-4ghz-late-2014-with-sapphire-nitro-rx-480-8gb-windows-16193-10-12-4/
This involved using creating a Win2Go install on external USB-SSD using Wintousb and Nando’s eGPU Setup 1.35 to fix code 12

Vega 64 Peak current Max reached to 650W.

Vega 64 peak max measured power draw at full load is 362W:

https://www.techpowerup.com/reviews/AMD/Radeon_RX_Vega_64/29.html

As the card has 2x8P PCIe power connectors it just peaks below the max 375W spec of those power connectors: 75W + 150W + 150W.

650W includes CPU and MB?

Tomshardware has peak power at 476W (<50ms) and sustained 402W for GPU

@nando4 

So technically the 400W PSU that came with the node should have worked.

@rolfl, I've linked a review measuring Vega64 power draw of 362W for the Vega 64, you've linked TomsHW that measuring 476W. Are some reviewers getting golden samples? You'd want at least max power draw + 10% to maintain stability and PSU longevity. Based on the Node's 400W PSU cutting out we can say either it has a poor quality PSU or your Vega64 card was drawing beyond the max the PSU allowed before overcurrent protection circuitry cut in to save the PSU.

@nando4, The two reviews seem to agree roughly on the average power measurements.

I think the peak power measurement may depend a lot on their measurement equipment.
My thinking is that the node PSU is probably meeting average ratings, but maybe lacking on handling the peak or transient power.

I may have particularly power hungry board. However, I did try it at the 2nd bios lower power bios setting, Turbo, Balanced, PwrSave, all with the same behavior, pointing to transient power issue.

Had you noise being emitted from you psu as soon as your card reaches max power ? I got my liquid cooled vega64 having some hiss and buzz sounds being emitted from my psu as soon as it goes full throttle....

600 silverstone supply had it quite loud and got quite warm fast, replaced it with an Lian Li 750W unit which still has a bit off this noice at a different rate (about twice as often within a given time frame) bout way more quiet then the old one...

Soon I will add my system & eGPU details or a build link to this my signature to give context to my posts

I tried Vega 64 + Node with internal power supply + MBP 15" 2017 (RP560)= crashes on both win and Mac OS 10.13

then got attached node to 750W power supply, now it works good under windows but not on Mac OS, it can't even play youtube videos. Am I missing something , Can you help

Thanks.
