I had my 600 duron running a 892, 1.65v...but it kept crashing in dues ex, so I decided to bump the voltage on my A7V to 1.70v. so I pop the top, change the jumpers and away we go. while windows is loading I get a page fault in explorer.exe....reboot....windows startup hangs...reboot....disk I/O error on A:...reboot....video bios then nothing....shutdown and stare at if for half a minute...boot....get bios, go to hardware monitoring, cpu temp72.5c,74c,75... look at cpu fan and notice it's not pluged in.
moral of the story: I'm an idiot.
