Overclocking Raspberry Pi2, Do I need heatsinks?

[zmokkie]

Hi guys,

First of all I want to thank the developpers for this very cool project.
I want to overclock my Raspberry Pi 2 from the raspi-config menu but I want to know if I need heatsinks before I overclock (ordered them but it will take some time to arrive).
And is the overclock preset Pi2 1000mhz the preset I have to chose for the best performance?
I also would like to know what CPU/GPU Split settings are the best for the Raspberry Pi 2.
Thanks for all the replies.

No you don’t need a heat sink, and i don’t think default it’s the best option. Since overclocking the core to 500 causes freezing and instability. Cpu/GPU should be fine as is, but if you would like to bump it up to 320 that’s fine too.
Check this out before overclocking.

If you are worried about overheating make sure it’s not in an enclosed case. If you would like an example of a lego case with air flow let me know.

Thanks for your answer. But you think overclocking is nescessary to run n64 and psx games?

[Omnija]

overclocking or not n64 isn’t optimized well for the rpi2. Overclocking for the psx i did see improved smoothness with high effect games such as twisted metal splitscreen and others.

And may I ask you what overclock settings/values you are using?

[Omnija]

gpu_mem_1024=320

# customized rpi2 configurations
# overheating protection
temp_limit=75

# disable boot up rainbow splash
disable_splash=1

# overclocking rpi2 settings
arm_freq=1000
core_freq=467
sdram_freq=467
