Question: I recently purchased a Raspberry Pi 3, which I understand to have the BCM2837 chip. When I purchased a codec from raspberrypi.com, I was asked to run:

cat /proc/cpuinfo

I was surprised to see the following output at the bottom:

Hardware : BCM2835
Revision : a22082
Serial : 

Why should I see this output from a new Raspberry Pi 3, instead of the BCM2837 chip?

Answer: 
I did some more digging and found [this.](https://github.com/raspberrypi/documentation/blob/master/hardware/raspberrypi/revision-codes/README.md)
Basically, the 'revision code' is the only useful bit of information. Look it up in this table to confirm what you really have. In your case, it's a Pi3B manufactured by Embest.

You shouldn't. That's the chip for the original Raspberry Pi.

1. Make sure you have a Raspberry Pi 3. Compare yours to the picture below. Check the markings on the chip and the PCB.

2. The output from `cat /proc/cpuinfo` will also tell you how many cores you have. RPi3 has 4 cores.
3. You could have an outdated OS that doesn't have the proper drivers for the CPU, causing it to not getting recognised properly. Which version of which OS are you running? Where did you get the installer from?
