When I woke up this morning, my laptop was going super slow, in both Windows and Linux... like it was running at 16MHz (if I had to guess). I still ran it for a few hours, trying to surf the net and chat on it while watching anime on TV. After a reboot, unplugging the power cord and plugging it back in, everything was fine, but I managed to some tests in FreeDos first.
Here is what this Core2Duo SP9600 CPU normally runs at:
During my supermegaslow 16MHz thing this morning, this is what the programs told me instead:
It certainly was not running at 800MHz, maybe it was running at 134MHz? Or 13.4MHz? haha. Has anyone ever had this happen to them, or understand what is happening here internally with this CPU? I remember seeing a post once by VirtualLarry about his MeeGo Computer stick going down to 200MHz or something like that when it was too hot, though I never experienced anything under the bottom speedstep value (600MHz) myself until today on this laptop because I've been using Pentium M laptops, which don't seem to have this "feature"... whatever it is.

Voltage is only at 17, multiplier is at 134x. I wonder what each step is at that rate? 1MHz? hahahSpeedstep 1.1 by Falcosoft
