Sysbench weird results when overclocked on Raspberry Pi 3
I tried overclocking my raspberry pi 3 from 1.2GHz to 1.7GHz and according to the command lscpu this worked. However I ran sysbench at 1.2GHz and at 1.7GHz and the total time result, when running at 1.7GHz was two times larger than at 1.2GHz and as I understand it my overclocking is backfiring. Am I misunderstanding something or doing something wrong? For more information: Sysbench command I used: “sysbench —test=cpu —cpu-max-prime=30000 —num-threads=4 run” I also have a fan cooling system and a copper heatsink on th RA

Try the raspberry pi forums?
Also please do not post duplicates. You asked this same question yesterday.

sorry, I could not fit this into the post, here is how I overclocked it (I added this text to /boot/config.txt):
gpu_freq=600
arm_freq=1700
sdram_freq=700
gpu_mem=200
over_voltage=8
over_voltage_sdram=7
disable_splash=1
temp_limit=90
the temp_limit didn’t affect anything anyway because my cooling kept it below 70C
