nadenislamarre I not have an Raspberry Pi 3b+ , but an friend have and noted :
don't have the overclock options working ...for this hardware, you can apply in future releases the overclock, changing the values as :
0) Off (1400Mhz)
1) 1450 Mhz
2) 1500 Mhz
3) 1550Mhz
is a same logical of overclock on Raspberry Pi 3B , maybe, can work and the performance would better !
