If i change the amount GPU ram inside the raspi-config, will it be persistent, so if i change to another SDHC memory with another OS it still will remember the settings or do i have to add this for every OS?
You have to configure everything for every OS and boot device. Nothing is persistent, as far as the OS goes. There are a few OTP (One Time Programmable) bits that can be set for certain things, like enabling USB boot mode on the older 3B model or changing the boot delay to wait longer for slow boot devices, and those are permanent (persistent) changes. But there is no non-volatile memory, like your typical Windows PC BIOS (all of that is on the SD card).
It is possibly to save some configuration files and use them on another card. For example, I have a copy of wpa_supplicant.conf with my wireless networks information, and I can just copy that to a new card to automatically connect to my WiFi when it boots. But that just simplifies the manual setup and is not the same as persistent, non-volatile memory (although it is possible to add those configuration files to a custom burn-n-boot image
to save even more time).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
