I'm posting for a friend.

Is it possible for a CPU to reach 100c? And if it is, what would happen? I recently overclocked a Phenom II 940BE to 3.3ghz and had a temp of 57c at full load(All 4 cores at 100%). Then, I edge up to 3.4, and run a stability test using AMD Overdrive. Right when the test started, speedfan displayed "100c" for all of my components, so I quickly hit "Stop". Afterwards, I had graphical glitches on almost all programs I'd open. Was it really at 100C? That's almost double the temperature from when I had it set to just 3.3ghz.

EDIT: Tried again. This time I went to 3.4Ghz with 1.4v(Can't go any lower), and speedfan didn't show any odd temperatures, but AMD Overdrive crashed, then I had graphical errors on my screen so I quickly restarted my PC to resume stock speeds to avoid damage. What could the problem be?

Do you only get those glitches when you attempt to OC?
You should easily get a stable OC of about 3.6GHz for that CPU with a voltage of about 1.475v +/- 0.01v. It's all about cooling, what are you using to cool your bad boy?
