If not I can check I only ran it on the old TITAN. It was -dev=5 at the time. Now it's -dev=7. The new TITAN X was -dev=4, and now is -dev=6. I ran two other script revisions on it (also for Argon2d only), as I described in here. I'm afraid you might be confusing the different GPUs with all those device number changes. Please always look at the reported GPU name strings: "TITAN" is the old one, "TITAN X" is the new one. Alexander
