5 years pass quickly :-D LOL
i have 40Mkeys per gpu(Is there any way to improve?)


Good speed increase if you only want to target the #61 puzzle address.

  • Only -c
  • Only one target: 1AVJKwzs9AskraJLGHAZPiaZcrpDr1U6AB
  • Make sure to use latest BitCrack version from github. There have been good speed improvements to the OpenCL version recently
  • Check your settings. For Cuda I have better performance with more threads (~512) instead of high processes

GL HF
One target or 45000 target won't change much.

Try this


bc.exe -c -u -d 1 --keyspace 1000000000000000:1FFFFFFFFFFFFFFF -i addrdata.txt -o ohmygodimrich.txt -b 72 -t 256 -p 2048

I get over 80MKey/s  on one Rx480 with 2,749,473 targets

As a general rule

-b is twice your computing unit       (Rx480 have usually 36)
-t 256   (I believe it is the max)
-p (depends on you GPU ram)   1024 for 4Gb and 2048 for 8Gb
