No amount of OC is guaranteed.
I run at 1535 using fan and heatsinkmoccor wrote: ↑Wed Mar 21, 2018 2:57 pmYeah I had zero experience with Raspberry Pi's until yesterday and most Pi 3 overclocks end at 1400. Mine seems to stay cool very well with the setup (heatsinks + Grizzly kryonaut + Super glue + fan). Was jw if someone had a 1400+ for their Pi 3 B+ and the settings - since text based OC is much different than BIOS/GUI
Try running this:-
Code: Select all
wget https://raw.githubusercontent.com/ssvb/cpuburn-arm/master/cpuburn-a53.S gcc -o cpuburn-a53 cpuburn-a53.S ./cpuburn-a53
If you are truly getting 1500MHz at 81℃, I'd be worried.
