2016 15" MacBook Pro (RP460) [6th,4C,H] + RX Vega 64 LC @ 32Gbps-TB3 (Mantiz Venus) + macOS 10.15 & Win10 1903 [itsage]
@itsage An actual modification to the power supply? I thought maybe they would just remove Power Delivery or did they leave the 87W PD alone?
My RX Vega 64 Liquid Cooled GPU is on life support. I noticed it's been running very inconsistently in the past week so I opened it up. There's green liquid pooling in several spots around the pump. If you look closely, a crack developed at the bottom of the plastic housing (right above PCIe pin split). I'm not really sure where to buy the replacement CoolerMaster unit. Please let me know if you have a lead.
how are you switching between the dGPU and eGPU in windows?
I have everything working (frankly better than expected) but the only way I can see to reenable the dGPU in windows is tedious.
Right now I boot into macOS to reattach the dGPU to the internal screen. Boot windows without goalque’s script. Reenable the 1901 memory space and restart.
Does that sound right? Is there a better way?
@magnesiumnitrate, I only used the Intel iGPU and eGPU with dGPU disabled. The process you described is what I would do to switch back and forth between dGPU and iGPU to power the internal display in Windows.
I found a new issue. Anytime I plug in an external monitor to the back of the eGPU the system locks up.
It’s been driving the internal display under load no problem. Only clue is that when it restarts occasionally I get error 12 in device manager.
I’m going to reattach the dGPU to the internal screen and try to run rp455/vega64 side by side with the Vega running the external monitor only. I’m super open to any thoughts you have though.
