Operating System: Windows 10 Pro 64-bit (10.0, Build 18362) (18362.19h1_release.190318-1202)
System Model: MacBookPro14,3
Processor: Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 CPUs), ~2.8GHz
Memory: 16384MB RAM
Vega 56 OC (with this OC you can 4k60 anything pretty much. don't think it's a vega 64 flashed bios):
Frequency +2.5%
Memory frequency: 950MHz max
Power limit: +50% (leave Razer Core X shell off for heat dissipation)
Texture filtering quality: Performance
Tessellation Mode: Override -> Off
Frame rate control: 62 (so it doesn't get carried away and overheat itself..)

eGPU hardware

Cable Matters 6.6 foot Thunderbolt cable https://www.amazon.com/gp/product/B01EGFFQN0

T5 SSD for game files (and Downloads folder, since I keep re-using when re-installing windows)

Razer Core X is best without the cover on, for heat dissipation purposes

Installation steps

Largely followed the community standard build page but with rEFInd spoof_osx_version enabled after updating AMD drivers

Exercise extreme caution when forcing power off. In my last update, I actually had a corrupt .dll so I had to reinstall windows again. I've noticed that I cannot install Intel iGPU drivers without first updating AMD drivers from 17.1.1 to 19.2.9 (19.2.10 after Vega eGPU). Screen would go blank during iGPU install, and I had to force power off / restore again. 

I tried to preserve the stock dGPU drivers, but gave up and used DDU, and leave PCIE 1901 disabled. Option boot works with 1901 disabled, and worst case, my windows update disabled, non directx updating self  usually has a system restore point to fall back on.

Sometimes (originally), I had to boot 3x to get into Windows: once with frozen login, once with infinite spinner, then once with "recovery  mode" --> continue to windows *magic*

  1. Install bootcamp, go through boot camp setup, restart
  2. Windows check for updates, restart (3x)
  3. Services -> stop and disable windows update -> create a system restore point "fresh install" I use ~2.5gb
  4. Safe mode DDU get rid of stock AMD drivers
  5. Option boot to windows, install bootcampdrivers.com 19.2.9 (later 19.2.10)
  6. Option boot to mac, re-install rEFInd (it should still have spoof_osx_version config uncommented)
  7. rEFInd boot to windows, download Intel driver. (I re-enabled windows update to install Intel driver, but apparently that one is a major version behind):
  8. shut down -> plug in eGPU -> option boot to windows -> device manager should show dGPU and eGPU, no iGPU
  9. run bootcampdrivers again to update Vega to 19.2.10 (so league of legends works..)
  10. (full restart -> option boot) -> device manager -> uninstall dGPU (not drivers)-> disable PCIE 1901 (View "by connections") *goodbye dGPU*
  11. rEFInd restart until that shit works (3x??) -> continue to windows 10 when it does the 'recovery' startup

Worth noting - I think my USB-C monitor may have an influence over the display drivers, even though I don't have that input active. The power sharing, thunderbolt handoff shit is probably messing with things, but my mouse is plugged into the monitor so I have no choice. I noticed that activating my monitor menu would start a windows chime during infinite spinner startups.

In any event, after 3x startup jank, the computer is a beast. I can get solid 60fps in PUBG 1440p with High/Very Low settings currently


Works great, extremely performant
PUBG 1440p 60 High/Very Low
Rocket League 4k 60
League of Legends 4k 60 (but I play 1440p)
Mordhau 1440p 60 (high)

These benchmarks are without overclocking the Vega 56 (stock Balanced mode + tessellation off and texture filter 'performance')



MAKE SURE TO CUT YOUR NAILS WHEN GAMING ON MACBOOK. Not only do space-gray macbooks get wrist-wear, but my work computer has chipped keys where my nails would be on CMD, A, and S keys 🙁
