Overclocking Pi4 with recalbox 7

[sergioad]

@Kruton I thought so, I also had issues at 2100, could a higher clock solve the problem? (I am thinking like the higher clocks could act like a save file bypassing a corrupt part of a game rather than a speaker adding noice at higher volume) righ now a pi could easily be overclocked at 2300 (I do not do it for safety) so it is worth the try

About the case I agree, sadly I could not configure the power button

By the way I am getting some occasional hang-up on ES, I do not know if it has to be with my overclock but it is worth to be shared, that way if the devs can check it they could solve it

Ok friends, I fixed my ES hang ups, I dialed back my pi to 1950 MHz and incremented the over voltage to 9 while keeping GPU the same at 750 and this far I have not had any ES hang up.

If you want my troubleshooting script package from when ES was failing that much HERE it is.

I hope with the findings of the community something could be made to solve the over 2000 issues, I prefer by much Recalbox to the other solutions and not being tied by this bugs would be awesome.

Here are my settings:

arm_freq=1950
gpu_freq=750
over_voltage=9

@sergioad i'm not familiar with overclocking the pi 4, but in the documentation i found this about the overvoltage

CPU/GPU core voltage adjustment. The value should be in the range [-16, 8] which equates to the range [0.8V, 1.4V] with 0.025V steps. In other words, specifying -16 will give 0.8V as the GPU/core voltage, and specifying 8 will give 1.4V. For defaults see table below. Values above 6 are only allowed when force_turbo is specified: this sets the warranty bit if over_voltage_* is also set.

if this is correct, the maximum value of overvoltage is 8?

and what about force turbo do you have enable it?

@rollbrett no, there are people running pis at over voltage 11, I use 9 on mine because the 8 GB model of the pi needs even more than the usual be 6 because it needs to acomidate the larger amount of RAM, in a 4 or 2 GB model 6 or 7 is more than enough, I have not enabled turbo

If you didn't enable the force_turbo, maybe your voltage 9 is seen as a 6?

[sergioad]

@LapinFou Ip sincerely doubt it

[Kruton]

I did not tested it by myself. But from official documentation and some forum posts by official staff, over_voltage bigger than 6 can be only activated when force_turbo is enabled. It is even possible to go over official limits by using parameter current_limit_override. But you are risking voiding your warranty if anything goes terribly wrong...

@phimjohn config.txt file only but be very carreful... be sure tu have a good cooling heatsink fan system, because Pi4 heats up a lot.

so whers this config.txt file in recalbox can you help me ???

@deneme Please read the topic, this is described a few posts above, you just have to read...
