-===== CPU speed ===== 
-  
-Often people choose to overclock their processors which is really only achievable from the bios or UEFI, or in Windows. 
-  
-It has been 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: 
-  
-<​code>​ 
-cat /​proc/​cpuinfo 
-</​code>​ 
-  
-To strip the output down to just the speed use: 
-<​code>​ 
-cat /​proc/​cpuinfo | grep -i mh 
-</​code>​ 
-  
-This is great but recently on a [[http://​ark.intel.com/​products/​75048/​Intel-Core-i5-4670K-Processor-6M-Cache-up-to-3_80-GHz|I5 4670K]] series CPU the clock speed was changed from 3.4GHZ to 4.0GHZ. 
-  
- ​[[http://​www.microsoft.com/​|Windows]] showed the difference using [[http://​www.cpuid.com/​softwares/​cpu-z.html|CPUZ]] but Vinux did not. 
-  
-The [[http://​www.fogproject.org/​wiki/​index.php/​Dmidecode|dmi decode]] command after quite a lot of searching shows the correct clock speed as well as other handy information like [[http://​en.wikipedia.org/​wiki/​Front-side_bus|FSB]]. 
-  
-<​code>​ 
-sudo dmidecode --type Processor 
-</​code>​ 
-  
-Now the correct speed shows after overclocking. 
-  
-Good luck
