Has anyone successfully overclocked a AMD 486DX4 100 or 120MHz to 150MHz? I couldn't find any reliable proof of it on the net, only this thread: My 486 (150MHz and Voodoo!). I think that Speedsys is misreporting am5x86 CPU there (this CPU was mentioned in youtube video below).
I've tried to OC two am486DX4-100 CPUs, both did work @ 120MHz (3x40) and @ 100MHz (2x50), but @ 150MHz, system wouldn't POST, even when core voltage was raised to 5V. It seems that my plan of having a 150MHz DX4 CPU in a GA-486VM motherboard - failed.
