## Usually wget files into a new directory to keep extracted files in one place, otherwise you will get logs/readme's filling up wherever you're currently in

mkdir mprime
cd mprime
wget http://www.mersenne.org/ftp_root/gimps/p95v298b3p95v303b6.linux64.tar.gz

## Assuming you're not already in the mprime directory you created if you're doing this all in one go from this article

cd mprime
./mprime

## If this is your first time extracting/using, it will ask if you want to join GIMPS- I usually hit 'n' since this is for troubleshooting only anyways

Your choice:


Number of torture test threads to run (4880):
Choose a type of torture test to run.
  1 = Smallest FFTs (tests L1/L2 caches, high power/heat/CPU stress).
  2 = Small FFTs (tests L1/L2/L3 caches, maximum power/heat/CPU stress).
  3 = Large FFTs (stresses memory controller and RAM).
  4 = Blend (tests all of the above).
Blend is the default.  NOTE: if you fail the blend test but pass the
smaller FFT tests then your problem is likely bad memory or bad memory
controller.
Type of torture test to run (4):

Usually run test 2 for CPU only, 3 for Memory only, and blend to perform both.
