Copy and paste the following command in your Raspberry Pi console:
curl -L https://raw.githubusercontent.com/aikoncwd/rpi-benchmark/master/rpi-benchmark.sh | sudo bash
This script runs 7 benchmark tests to stress your Raspberry Pi hardware:
- Speedtest-cli test: Calculate ping, upload and download internet speed
- CPU sysbench test: Calculate 5000 prime numbers
- CPU sysbench test: Multithread with 4000 yields and 5 locks
- MEMORY RAM test: Sequencial access to 3Gb of memory
- microSD HDParm test: Calculate maximun read speed for SD
- microSD DD write test: Calculate maximun write speed with 512Mb file
- microSD DD read test: Calculate maximun read speed with 512Mb file
Rpi-benchmark script will show your current hardware (overclock) settings. After every test, it will show the current CPU temperature
You don't need to download any program, compile sources, etc... It's so easy!
Just copy and paste the following command in your Raspberry Pi console:
curl -L https://raw.githubusercontent.com/aikoncwd/rpi-benchmark/master/rpi-benchmark.sh | sudo bash
The rpi-benchmark script will start in 2 seconds
Yes, overclocking your RPi will give you more power for your CPU calculations, more speed while read/write into your memory ram and better speeds while read/write into your microSD card.
If you use your RPi as a MediaCenter with Kodi or to play games with RetroPie, you will find a nice perfomance boost.
I strongly recommend to use some cooling on your RPi to avoid CPU throttling (at 85ºC)
Edit your /boot/config.txt file and paste the following code, you can adjust values to get more or less overclock:
force_turbo=0 #Enable cpu-overclock over 1300MHz (default 0)
avoid_pwm_pll=1 #Enable no-relative freq between cpu and gpu cores (default 0)
arm_freq=1300 #Frequency of ARM processor core in MHz (default 1200)
core_freq=550 #Frequency of GPU processor core in MHz (default 400)
over_voltage=6 #ARM/GPU voltage adjust, values over 6 voids warranty (default 0)
sdram_freq=575 #Frequency of SDRAM in MHz (default 450)
sdram_schmoo=0x02000020 #Set SDRAM schmoo to get more than 500MHz freq (default unset)
over_voltage_sdram_p=6 #SDRAM phy voltage adjust (default 0)
over_voltage_sdram_i=4 #SDRAM I/O voltage adjust (default 0)
over_voltage_sdram_c=4 #SDRAM controller voltage adjust (default 0)
gpu_mem=256 #GPU memory in MB. Memory split between ARM and GPU (default 64?)
gpu_freq=550 #Sets core_freq h264_freq isp_freq v3d_freq together (default 300)
v3d_freq=500 #Frequency of 3D block in MHz (default ?)
h264_freq=350 #Frequency of hardware video block in MHz (default ?)
dtparam=sd_overclock=90 #Clock in MHz to use for MMC micrSD (default 50)
dtparam=audio=on #Enables the onboard ALSA audio (always use this ON)
dtparam=spi=on #Enables the SPI interfaces (default OFF)
temp_limit=80 #Overheat protection. Disable overclock if SoC reaches this temp
initial_turbo=60 #Enables turbo mode from boot for the given value in seconds
start_x=1 #Enable software decoding (MPEG-2, VC-1, VP6, VP8, Theora, etc)
overscan_scale=1 #Respect the overscan settings with the use of an LCD display
