What settings are used in the UBCD version?
Is it Small FFT, Large FFT or Blend?
The Prime95 in UBCD is run with the default setting. That is, Blend.
If you want to configure Prime95 before you start, you can run this in your command line:
/opt/mprime/mprime27 -m -w/tmp/torture-test
The mprime wrapper script will create a temp directory every time you run a torture test. So you can use any working directory besides "/tmp/torture-test".
Cause it would be nice to be able to choose.
Good idea. I might add that feature in the future.
As running from DOS (or what it´s called) is much better than inside an OS, as the OS itself takes cycles and ram.
Your argument here doesn't make sense. First, Prime95 doesn't support DOS at all! Second, DOS is an OS, which takes cycles and ram too. You should refer to a self-bootable program instead, but unfortunately few people will develop stress-testing programs for self-booting.
