I've already posted this bit of information at notebookreview.com, but I'll also write it down here: my new CPU surely isn't defective because it has been tested earlier in an HP Pavilion DV5 and it didn't down-throttle at all, not even at 90 °C.
Having read this subforum's readme, I think I'll link in a BIOS of that model, hopefully that way my thread might get a response.
So I choose the HP DV5-1150EN, some of those were shipped with Turion Ultras:

And here's my BIOS, latest version (1.26):
download. Although I doubt that is a full BIOS image there.
I've also attached the output of dmidecode.
P.S.: I haven't checked, but I think the HP BIOS is for machines with an AMD M780G chipset that is also in my Acer.
OK, here's a better one:
HP tx2500z BIOS. These were shipped with ZM-86 CPUs and have the M780G chipset.
