GPU mining with W6800X Duo and W6900X + XMRig on macOS Big Sur

Post by macminergod »

Our first Crypto mining tests with the Apple's new AMD GPU's in the 2019 Mac Pro. We used XMRig and OpenCL to mine with the AMD Radeon PRO W6800X Duo 64GB and AMD Radeon PRO W6900X 32GB simultaneously under macOS Big Sur 11.5.2. See our new guide on how to crypto mine using your Mac's GPU with XMRig here.

XMRig and OpenCL only recognized 3095 GB of ram per card for some reason. Thus, hash rates were very low as the maximum GPU was not being taken advantage of (if someone knows how to fix this, please post below). In order for XMRig to simultaneously mine all 3 GPU's, we had to edit our XMRig's configuration with additional indexes, see below. Obviously, full mining potential was nowhere near achieved for both these cards and we'll be brining more tests from Boot Camp and other miners soon.
