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:

clKernel is paramater that defines the type of OpenCL kernel:

Phoenix miner uses 1 - optimized - as default.
