GPU1: clSetKernelArg (-48) Fatal error detected. Restarting.

Sometimes PhoenixMiner will exit with the following error:

GPU1: clSetKernelArg (-48)
Fatal error detected. Restarting.

In such cases we suggest to use -clKernel 0 parameter in your advanced configuration of Phoenix miner. Click on [Advanced] tab or pencil icon to edit the simple config. New config will look something like this:

-worker (WORKER)⁣⁣ -pool (POOL:ETH)⁣ -wal (WALLET:ETH)⁣.(WORKER) -pass x -eres 0 -proto (AUTO)⁣​ -clKernel 0

clKernel is paramater that defines the type of OpenCL kernel:

  • 0 - generic
  • 1 - optimized
  • 2 - alternative
  • 3 - turbo

Phoenix miner uses 1 - optimized - as default.
