On a Sapphire Nitro ITX RX570 4G I get instant Blue screen whenever I try to run optimize or Benchmark in Ethash and I get red 0% on Eth/Pascal. All stock bios/speeds Adrenaline drivers, Windows 10 latest updates. And unless I clear the files at /users/"user"/Appdata/Roaming/GatelessGateSharp, whenever I try to reopen the miner, it remembers the last state before the blue screen, starts, optimizing and crashes windows, in an endless loop.
Any idea what's happening?
This probably means that GGS does not have a proper device profile for your graphics card's memory module.
What do you see under "Memory" on the dashboard? There should be the name of the memory vendor.
