This is a sysmodule/service for Atmosphere and ReiNX that uses IPC's to communicate with its companion NRO, Freeset. This allows you to use any clock speed I've found on the Switch. The only restriction I have put in place is that you must be plugged into an official charger or docked if you are crazy enough to want to use the highest two GPU clock speeds. I am leaving it completely up to you to choose what clock speeds you want to use. Be careful.



Intructions:

• Atmosphere: Copy over the contents of the zip and reboot your system to load the module. Open Freeset and use that to send over the clock speeds you want.
• ReiNX: Create a folder in your ReiNX folder named titles if there isn't one. Copy the titles folder from the atmosphere folder to ReiNX/titles. Open "010000000000C235" and move the boot2.flag to the same directory as the exefs.nsp file. Reboot and freebird should now be working on ReiNX.

X turns freebird's clock setting feature on and off. Remember to turn this off before putting your system to sleep. I'm working on it™, but it will cause and require you to fully shutdown and restart your Switch if accidentally left on. When on, freebird will check and set the clocks if they don't match what you choose. When turned off, your clock speeds will be reset and no longer forced.

A sends over the clock speeds shown/chosen from the menu. Up and down change the currently selected option, left and right change speed.

If I missed anything, don't be afraid to ask. I'm open to suggestions too.

I'd like to thank @taggen86, @nabelo, @mathew77, @vanraz86, and @Kirby567fan for taking the chances and testing it. Thanks guys!

Yup, that's a big advantage of Freebird. The other is the ability to quickly adjust settings on the fly based on your current needs for performance vs. battery consumption . IMO this gives Freebird the edge over Sys-Clk, though both approaches have their advantages. I guess the ideal clock control solution would support both methods; maybe someday

Just got freebird, now I just need to read up on what over clock options not to use, might use the suggested clock speeds from sys-clk because that one has capped speeds for safety.

What would be the ideal settings for Mortal Kombat 11 in docked mode? (For highest FPS and best graphical performance)

 

[crow132]

guess what? mortal kombat 11 plays at 460 mhz in handheld mode, this time is not a first party game... the switch sure is starting to fall a little short..

Playing MK11 handheld with CPU-1020 RAM-1600 and GPU-768. I don't notice much if any resolution or graphics difference from stock clocks but framerate sure does feel a lot smoother.

It’s pretty interesting as Nintendo is allowing higher clocks in 3rd party games, I don’t have the game to test, a short clip showing the clocks in freebird would be nice

Loving this update, best oc program.

 

[crow132]

any of you guys tested freebird on 8.00? is it known to be working?

It doesn't work for me

thats a shame

i though so since sys-clk had to be updated

Except not all the games need overclocking, and some act unstable to OC and crash right away, there are a few that benefit from down clocking even.

This is not true, at least not anymore. OC instability was an issue on older Atmopshere versions, not an inherent behavior exhibited by games or the system. Update your Atmo or use ReiNX and you will not have OC instability.

I've been doing extensive tests since this utility released, and max available OCs are fully stable. I have been running them exclusively since Freebird released with no issues. For my own sanity regarding battery life I just run a slightly bumped GPU / RAM increase while on handheld, but from testing max available clockspeeds I haven't run into any issues outside of said battery life.

Very few games benefit from underclocking, it's almost not worth bothering. The default clock speeds don't draw much power to begin with and are already fairly low, and underclocking it further will not drain significantly less to appreciably improve battery life in the few games where this would be useful eg. Baba Is You. The biggest power draws that you'll have a better chance of saving power from come from the screen and radio. By the time you'd save power from underclocking, the Switch will be so slow and unresponsive it's not worth bothering.

Keep in mind you don't have any manual control over the voltage, which is a big factor regarding the power draw. We just have to trust that the voltage even drops at all appreciably when underclocking, otherwise now you're Switch is slow while drawing the same amount of power.

I wonder, if you run this at max OC settings, would games like Fire Emblem Warriors allow you to choose the quality option while in handheld mode?

No. Clock speeds aren’t the only difference between docked and handheld, games can detect whether you’re in docked or handheld and lock or unlock certain things depending on the state

so, gotta ask... @JK_

any plans on supporting 8.00?

Once this gets merged it should be fairly simple to add 8.x support https://github.com/switchbrew/libnx/pull/266

Now that's a bold generalization, let's pretend there isn't a lot of 8-16 bit like indie games, ok.

Not really. Read the rest of what I wrote.

There's no guarantee that you'll save much power from underclocking in the first place. Airplane Mode + screen brightness will bring you far better, and much more tangible results. Also I specifically called out the example of Baba is You

Yeah, but it might take a bit. I was working on expanding and improving the IPC stuff when 8.0.0 dropped. So, now I have two things to finish before another release. I guess the good news is that the new IPC server stuff seems to work fine so far, just gotta get some small things worked out.

 

[Clydefrosch]

I'm unfortunately not able to try this myself for a while, but has anyone tried to scum the lightning dodge game and potentially the chocobo balloon race in Final Fantasy 10 by underclocking the system?

Any updates on SX OS users being able to join the overclock party?

why are you asking here
we're not tx go ask in their forums
