just pulled a couple of S3s out of the garage to test them lol - what sort of share size should i be looing at getting to solve a block... its been a while since i mined anything - had a few S1s running pencil mods a few years back on here!
A few CKCOLO blocks back, someone hit it with average of 500gh...
Likely from an S3, probably the luckiest block I have seen in a long while.
Good luck and happy mining!
