What does it mean when an old CPU (Phenom II X6 1090T) runs fine on three different boards, can run Prime95 all day with no problems, and never gets hot.
But... when running Intel Burn Test for only a few early passes on default settings, it freezes the machine on two boards and black-screens & freezes the machine on the other.
I suppose the obvious conclusion is that the CPU is defective. But why the near instant fail with IBT, while never failing with Prime95?
I have verified the memory in all 3 boards is stable. No OC involved. All machines running fresh installs of W10.
