Machine Check


STOP: 0x0000009C (0x00000004, 0x00000000, 0xb2000000, 0x00020151) …. Once I turned off automatic reboot, this is the error I got on the DFI GME855-MGF.
What it means in short is that the Pentium processor threw a specific exception (Machine Check Exception) meaning that it detected there was an internal CPU-specific error.
The most frequent reason is overclocking (yup, I’m overclocked from 1.8GHz to 2.15GHz), bad or over stressed power supply (so voltages fluctuate), fan failure or bad memory.
Net, net, I turned down the overclocking from a 18x multiplier to 17x against a 200MHz data bus and things seem very stable.
Interesting that this machine check then causes a continuous failure to boot with a different exception in the nVidia driver.
Any way, you are warned, if you get this, on a Pentium M 735, then turn down the overclocking.
