And if it kills your WiFi connection:

Name: sdhost
Info: Selects the bcm2835-sdhost SD/MMC driver, optionally with overclock.
N.B. This overlay is designed for situations where the mmc driver is
the default, so it disables the other (mmc) interface - this will kill
WiFi on a Pi3. If this isn’t what you want, either use the sdtweak
overlay or the new sd_* dtparams of the base DTBs

firmware/boot/overlays/README at master · raspberrypi/firmware · GitHub

you should try out the new " sdtweak-overlay.dtb " like:

dtoverlay=sdtweak,overclock_50=100

K-plan you legend . Have you tried this, running stable? If so, i’ll look at adding it to dietpi-config.
