Go up one level in this thread


Possibly, though I ran them the same way. I disabled all of my startup
applications, rebooted, and then ran Hiarcs/Fritz/18.16/19.03 in succession. I
even rebooted 2 more times with HT On and reran the tests and came up with the
same results.

I guess we need someone else with a P4 system with HT to run these same tests.
