4x 6600 XT/ Hiveos

GPU1: Unable to prepare kernels: clCreateKernel (-46)

-clkernel 1 - auto select. work -clkernel 0, but stale shares 2-4%.

Ubuntu 20.4.3 ( no HiveOS)
AMDGPU-PRO-21.30 drivers amdgpu-pro-install -y --opencl=rocr --headless

I am not using -clKernel just PhoenixMiner decide as it will pick the right one, see releasenotes.

The only settings for RX 6600 XT are as follows:
-acm
-gt 14
-ttj 70
-hwm 2
-coin eth

MH/s 28.719 ASRock Challenger Pro 8GB RX 6600 XT

I you have any ideas for improving hashrate share your ideas.

are you sure?

-clKernel <n> Type of OpenCL kernel: 0 - generic, 1 - optimized, 2 - alternative, 3 - turbo (1 is the default)

Failure to specify the clkernel will default PM to use clKernel1 - see the command list in post 1 reproduced above for convenience.

To increase performance you might want to see if gpu tuning is working under your setup? -gt x ( i see you have -gt 14 which is more or less default setting which is 15)

Press z during mining to see if they will autotune to find best -gt setting and if so wait till finished and check the results by pressing s and apply it in config or command line.

I know it's the default but since 5.8b kernels have changed for the RX 6600 XT specifically. Did you actually read the ReleaseNotes.txt?
- Implemented optimized kernels for AMD RX6600XT cards

The -gt 14 came up after autotuning. Will fiddle with the -gt -cclock -mclock -cvddc settings to see if I can improve it. On Windows the same card gets more than 32 MH/s.
