Implemented new "turbo" kernels (-clkernel 3) for AMD Polaris cards that can work with the current DAG sizes over 4 GB. Note that -clkernel 3 uses double the VRAM and will provide slightly faster hashrate with slightly higher power consumption. You can use the -rvram command-line parameter to specify how much VRAM to be left unused

Please let us know if you have any problems or questions related to PhoenixMiner 5.7b.

Tried the -clkernel 3 on my RX 480 8GB and got lower hashrates than -clkernel 2.
I'm on windows 10 20H2, Radeon Software version 21.6.1
I'm only using the -vmr 25 parameter and -gt 69 as per benchmark suggestion.
Everything else is default.

Your current gt value 69 is not the optimal for -clkernel 3. Put -gt 0 in your settings to find the new best gt value for -clkernel 3. After that you can put -gt NEW_BEST_GT_FOUND_VALUE in your settings.

Thank you very much. I will look into that.

Aaaand nothing changed.

If you have amd rx470/480/570/580 GPUs you will get +0.1mh/s per GPU with -clkernel 3. You will not get increase with Vega, Navi or Nvidia GPUs.

The option -clKernel 3 is ignored for all GPU, when i use -clKernel 3. nitro+ rx570 8g samsung, stock bios.

You are using very old drivers. Update the amd gpu driver.

which version bro? im using 20.4.2

Increase your VRAM to (NUMBER_OF_GPUS+1)*8 GB. If you print the beginning of your log file I will tell you why clkernel 3 is ignored.

Sorry, you can't run -clKernel 3. Your GPUs are some weird model that can't allocate more than 4GB per single memory block. Run clinfo from command prompt and you will find that your ' Max memory allocation:' is somewhere about 4GB. My RX570 has 'Max memory allocation: 8321499136'

maybe due to driver?, i find st in this topic https://github.com/ethereum-mining/ethminer/issues/1966
