Mystwalker,

I've been running the stage1's of a few 70-digit curves B1=2.9G, later I'll transfer the stage1 result to a barton. Was thinking about running B2 out to 1.5T, in slices of course.

Any suggestions for comand lines using 756MB and 1.5G of memory.

Yes I know doing it just for fun at the 70-digit level.
