Illegal Memory Access #78

Open AndrewReitz opened 3 years ago

AndrewReitz commented 3 years ago

After a few minutes of running the cuda mining stops after the error

thread #0 failed with error :59 "an illegal memory access was encountered"

Output from the console here. Let me know if there is any more information I can provide.

RandomX is useless on GPUs anyway (note it's only making one thread on such a powerful card)

Compile CPU-only version and separate CUDA version and run them separately but parallel, then they can do different algos (if on MoneroOcean or other multi-mining supported pool).

Or if you only want RandomX based algos, forget using the GPU it's a headache and also horrible hash-per-watt (as designed).
