I've just upgraded my rig from a single nvidia gtx 660 to twin sapphire R9 290 vapor... I had cracked a set of three unix SHA512 hashes with the nvidia card and managed to get all three accomplished in approximately 4 hrs with oclhashcat setup to use the nivida gpu. I've since rerun the process with the R9s (linked) and I can only get two of the three. I've got it using a wordlist attack with the same wordlist used with the nvidia card. I know the password is in there. If i reduce the wordlist used to the three known passwords it ignores one of the passwords. Is it possible to get a false solution? and if not why would it miss the known password?
