    So, is it real that 1785 Overclocking in Retroarch can damage your Switch? Has anyone a damage switch by this Method...?

    Theoretically it's safe since the SoC was meant to run at a stock speed of around 2ghz. The problems are that the switch's cooling is meant for that lower clock (but it still cools fairly well anyway). The battery can also be a point of concern, with power draw and such. Personally, I've overclocked to high speeds frequently and my fan still didn't get loud, however I do have a thermal paste replacement. I still believe it shouldn't be a huge concern unless signs show up like abnormal heat output, like PS3/4 levels of heat.

    So, if you play games at the max clock for.... let's see 2 hours in a row, it'll be dangerous...?
    PD: I've played Smash Ultimate for 6 hours in a row, my Switch gets a lot of heat, but when i play Retroach it doesn't get that hot.

    2 hours isn't much to be concerned about, it's more about the lifespan of the console. The difference in your games is that they use the processor in different ways; 1st party games will be much more optimised for the hardware, therefore more heat. An emulator, not so much, but overclocking is an easy solution of sorts for performance, also very little GPU usage. I'd say OC in retroarch is safe, heavily overclocking original switch games for long periods is where I'd get worried.

    The hardware was designed around the system running at 1785mhz CPU and 921mhz GPU. So it should be fine

    The ones the Switch uses are meant to run at 1785mhz :P

    Hi,

    I'm new to home brew scene and just found this thread. I hope someone here can answer my question.

    I've just installed Retroarch to run some N64 games. The performance with overclock is great. There is just one concern I've got:

    As I intend to use overclocking exclusively for n64 emulation, I`d like to know if the overclock settings I apply in retroarch will be permanent and also apply to other applications/games beyond retroarch.

    Lets say I want to play Mario 64 at 1785mhz and afterwards I want to play one of my NSPs without any overclocking. Do I have to set the CPU Overclocking settings in Retroarch back to 1020mhz before I close the app and launch an nsp, or does the retroarch configuration have no effect on other applications?

    Thank you guys in advance!

    It has no affect on other apps. If you OC within retroarch it's only while using it you'll have the OC.

    not every game is needed to run at full speed

    Thank you very much! So I'll enjoy N64 emulation with OC :)

    Hey all

    Thanks for the info, very helpful.

    Just a quick one - would it be at all possible to clock further than 1785? I understand the risks and all but would like to know if it can be done.

    Ta in advance.

    it's possible to do and already there are some tests done in backyard of Switch scene to tests safe values (that will not shutdown your Switch because of voltage jumps at stress) and what will be the best way to share it. Because for now it requires recompiling Atmosphere with additional code.

    Sorta what masa said.

    The patches mentioned allow adding additional CPU and GPU tables for Erista and Mariko, removing the 1785/921 CPU/GPU limit on Mariko devices (Mariko has higher clocks, but they're locked based on regulator type), and overclocking ram on Erista.

    No extra clocks for Erista will be included if I ever distribute the patches, you'll need to add them yourself, 1785 CPU and 921 GPU are already very dangerous.
    Mariko with the limiters removed can go to 1963 CPU and 1267 GPU (which is "probably" safe)

    I am very interested in testing these patches, I have modded switch with replaced ram chips. they support a higher frequency than the default chips. I also have an external cooling system for my switch based on TEC, so there should be no overheating(48-50C with 1785/1600/921 ).

    the cooling and soc are doable,
    is the motherboard safe feeding more amps to soc, thats the only concerned...

    Cooling is whatever, the stock cooling can handle GPU at 1267 with all cores under full load just fine. It's way better than people make it out to be.
    30+W on a board that's only intended to take around 10W is a big yikes though. The CPU and GPU voltage increases are also... discomforting...

    Where can I find the voltage tables for the Switch HOS kernel? Do we use the same voltages for the respective frequencies as the Shield Android kernel?

    The tables are in the pcv sysmodule.
    For Erista, the coefficients are the same L4T (ODN/odin tables, specifically), yeah.

    Btw if you are interested in the patches, (at least for me, but im dumb so idk) they break sigpatches at times
    btw even 921mhz gpu isn't very safe on erista, hell ram oc is the safest one AFAIK (probably the most helpful for performance )
