use this one "update_1000.tar.gz"
you mean use only one file to update? "update_1000.tar.gz"
but bitmain gives two files, just ignore it and install the second file?
thanks
The first file is the software that should already run on your machine, the second will give the higher hashrate. You could as well use both, but the "update_1000.tar.gz" as last.
