PIII processor serial # output

[Jerboy]

The makeshift computer I'm using right now has an Intellite Pentootium III and I realized it supports processor serial number access through software. Ok I'm sure we all know it exist, but has there been any useful purpose to this ever?

Nope.

It's fine as a unique machine identifier, but it's exactly the same as an NIC having a unique serial number.

To my knowledge, no software makes use of it, except perhaps Intel's CPUID programs to tell you what speed your processor is.

the PSN doesnt say how fast your comp runs (PSN is a unique number in all computers). All it does is identify your machine as you - it's just a serial number built into the hardware. It was supposed to be used to identify your machine as you on the internet (as no 2 PSN's are the same) for online purchases, etc but then Intel later figured out that it was a good tool for hackers to identify you with.

So Jerboy, you're 17 years old, well isnt that interesting (your sig).

Little introduction doesn't hurt 😉

Anyways I can't justify the reasoning behind processor serial # read out. Sounds to me it is done in favor of marketing and profiling company.

The CPUID program makes a calculation based on the PSN. The Intel program can tell what speed your processor is supposed to be and if it has been overclocked.

I don't think so. The CPUID program tells me the supposed frequency even when I have processor ID function disabled through BIOS.
