PODP5V83 - where Pentium OverDrive Processor 5V 83MHz?)))

Oh! I always set the voltage to 3.3v, until then I increased to 4v......

I jump the wrong setting.......

Now, POD83 @83MHz running quake at 19.3 frames per second with fake cache.

Great!
As already mentioned, those quake values are not really useful, you have to repeat it with a PCI graphics card.

Yes, it is a upgrade CPU, so it works on 5 volts only mainboards.
On the other hand, the CPU supports also voltage detection, so when the mainboard provides the 3.5 volts, the voltage regulator on the cpu is not used.
Why it works now with 4 volts setting is not clear.... But not very important I think.

Thanks. Very exciting to get 83MHz back.

OK, I will do more test.

This means an average POD83 can run on normal voltage settings as AMD DX5.

I don't think that's true, you have to provide it 5V for correct operation

What would be then the purpose of the VOLDET pin on the CPU?

As far as I understood, VOLDET tells the mainboard, weather a 5V CPU is present or not. But can it tell the CPU weather the socket provides 5V or 3.45V??
