Pi5 performance settings

[Aethermind]

Hi everyone

I am opening this thread to keep trace of the available knowledge, configuration tips and current technical consensus, about the recommended settings for the optimal Raspberry 5 CPU performance on Zynthian.

The first and main topics I would obviously like to raise are:

• Overclocking

• RAM settings

As for the first, I have noticed a perceptible improvement in the overall system capability to sustain complex snapshots, with heavy computational workload in Vangelis at medium overclocking, although not as significant as with Pi4.

As for the second, there seems to be ample discussion in the Raspberry Foundation forums, about marginal advantages of tweaking the system memory management with 8 Gb of RAM size.

Any opinions?

Cheers

By the way, I wonder if some kind of up-to-date CPU and RAM optimisation is already implemented in the latest Vangelis releases.

If anybody wants to try overclocking, I recommend reading the advice in “Zynthian Overclocking”:

Zynthian overclocking

Probably you have read that the Raspberry Pi 5 is not so tolerant to overclocking as his predecessor. For this reason we have changed the default overclock value to None for all Pi5 configurations. This doesn’t mean you can’t try overclocking. Indeed, if you have a Raspberry Pi 5 and a good heat dissipation system, like the Kit V5.1 does, you probably could overclock your zynthian. For doing so, you should proceed step by step like this: 1.) From the “Hardware Options” in the webconf panel, c…

Thank you @tunagenes, for reposting and refreshing the knowledge already provided by @jofemodo, which I were aware of.

Indeed, I was asking myself if anything newer and relevant had emerged in the meantime.
