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?
