The best speed for you would be -b 64 -t 256 -p 2048. only the creator knows the intricacies of verification. But BitCrack no longer works fine, it does not show the correct digits for scanning.
Thanks, but I am trying to learn a little bit about how workloads are distributed to GPUs as well as optimizing my gpu...so could you explain how you decided on those values or was it trial and error with a similar gpu?
I did a test of finding 40 keys from the puzzle32. Did many times different parameters. Conclusion is the best speed. My card is similar to yours RX 570 Nitro+ 8GB. The big minus of BitСrack is that it does not show the correct calculations. and conservation does on incorrect calculations. after restart you will start from the saved file. Thus, the key can be skipped.
