Thanks for the kind words, fairglu!

7 out of 8 cores of an AMD FX8350 running at normal speed (4 GHz)
The process took around 1920 hours, from May 14th to August 2nd

(When I did 700 in January, I had a stroke of luck and found a solution in under three days!)

Now, if you had 1920 such systems and somehow forced the superblock difficulty to 2500, how many hours would it take to find one 752 digit 6-tuplet?
Just a thought...
