Overclocking SD Card speed

Post by McGyver » Thu Apr 20, 2017 2:22 pm

Sorry if this topic is already known...

Do you aware that a Ultra High Speed (UHS) mode on SD cards is not used by default on the raspberry PI?
The SD card access speed needs to be "overclocked". Take care: not all SD cards support this. In this case you can reduce the setting until it works...

I got Sandisk extreme pro running on 100MHz but Samsung EVO didn`t work on that speed even if it is listed as UHS-I.

Interesting, thanks for sharing! Have you seen any noticeable performance gains in things like boot-time, etc?

Honestly not a lot... I started booting both of my builds on the same time. One on 100MHz, the other on 83MHz. The 100 MHz Version was maybe 2-3 sec. faster in booting. My conclusion: don`t spent so much in high speed expensive SD cards if you aspect a huge increase in speed.
