CPU speed

Often people choose to overclock their processors which is really only achievable from the bios or UEFI, or in Windows.

It has taken a long time to find the answer but when overclocking the true clock speed has never been shown in nix.

Often the command used which shows the various stepping speeds a processor will go through is:

cat /proc/cpuinfo

To strip the output down to just the speed use:

cat /proc/cpuinfo | grep -i mh

This is great but recently on a I5 4670K series CPU the clock speed was changed from 3.4GHZ to 4.0GHZ.

Windows showed the difference using CPUZ but Vinux did not.

The dmi decode command after quite a lot of searching shows the correct clock speed as well as other handy information like FSB.

sudo dmidecode --type Processor

Now the correct speed shows after overclocking.

Good luck
