To add on to my research. When resuming from Prime95, you cannot do -resume -save. Otherwise you won't find any subsequent factors.

What you can do is search in steps. [b1] 100000 [b2] 1000000-2000000

Onece you find a factor and wish to continue with that same B1. You can manually add it to the input file. And as you did the first time you need to change the checksum of the input file that looks like that.

METHOD=P-1; B1=xxxxx; N=(2^yyyy-1); X=0x...(the inputed X0 from Prime95).........; CHECKSUM=.............; PROGRAM+GMP-ECM .....
