Tutorial Gaming Hardware Hacking Homebrew 4IFIR MOD: The simplest way to overclock | CPU 2397 MHz GPU 1536 MHz RAM 2131 MHz

[Cooler3D]

4IFIR MOD v0.3
UNLEASH THE TRUE POTENTIAL OF YOUR CONSOLE 2397/1536/2131 MHz
Now with experimental support for ERISTA (first gen Switch) 2295/1075/2131 MHz

According to popular requests from users of 4PDA and GBATemp, I made a modification designed to TRUE overclocking Nintendo Switch.
P.s. Sorry for my English, i am from RUS

Spoiler: How-to

Spoiler: WARNING

This mod is intended for those who really want to squeeze the most out of their console, but at the same time have not mastered the independent development of half a hundred terms, and are not ready to spend tens of hours on shamanism of components scattered across the Internet - all kinds of relevance. On the good, this assembly should not have existed, since the high threshold for entering the topic was a natural barrier for inexperienced users, protecting them from self-harm. By installing a modification without theoretical training, you relieve the author of responsibility for any possible consequences, including irreversible damage to the components of the device, and assume the risks. If something goes wrong, I will not take care of the consequences for you. You knew what you were doing and that is the price of the time you saved.

Spoiler: REQUIRED

HOS 13.2.0 | Atmosphère 1.2.5 | Reading the warning.

Spoiler: INSTALL

Grab necessary patches from the repo, then compile sys-clk, ReverseNX-RT, hekate and Atmosphere (or loader only) with devkitpro, then defeat Kratos. Just extract 4IFIR.zip to the root of Switch SD, with using external card reader. Turn on your console. Enjoy the result.

Spoiler: DOES NOT WORK

Try fix.

Spoiler: DID NOT HELP

Try another fix.

Spoiler: DID NOT HELP

Have you read the instructions carefully?

Spoiler: YES, OF COURSE

Are you sure?

Spoiler: ARE YOU FKN KIDDING?

Where was the memory card when the mod was unpacked?

Spoiler: IN THE CONSOLE

What was your next action after unpacking?

Spoiler: RESTART

Did the instructions mention a reboot? After unpacking the contents of the archive, the console should have been turned on.

Spoiler: BUT IT WAS ALREADY...

That's it. Try repeating the installation process, this time following the instructions verbatim.

Spoiler: FEATURES

• Overclocking up to 2397 Mhz for the CPU, 1536 Mhz for the GPU, 2131 Mhz for the RAM (the exact ceiling is different for each console).
• Automatic overvolting.
• Unlimited video recording in all games.
• Wireless video streaming with increased bitrate, 60 frames per second, to external monitors - almost without delays.
• Dock mode emulation.
• Accelerated charging.
• Reducing the current threshold for the Official Charger.
• Drastic reduction of cooling system noise.
• Overlay with FPS and system metrics.
• Over-the-screen menu for on-the-fly control of the listed features.
• Background FTP server.
• Necessary for the joint work of all of the above are system modules.

Spoiler: CREDITS

• KazushiMe for overclocking suite for Switch
• devkitPro for All-In-One homebrew toolchains
• masagrator for ReverseNX-RT and BatteryChargeInfoNX

Running this is at the end users own risk.
This and any homebrew that changes operation within a handheld/console has the potential to damage the unit.

20.01.2022 NOTICE:
Several people from the RetroNX community are convinced that YOU are too dumb (literally) to use console overclocking if you are not able to build all the packages from the source code with the necessary changes by yourself. They are so convinced of this that in a desperate attempt to stop the distribution of this modification, they have gone so far as to threaten and speculate on the GPL license... To use the GPL for what the GPL was created against, oh my god.
The download link is temporarily disabled, I will restore it as soon as I make a repository with everything necessary, including a full indication of the licenses used in the modification of the components. I was going to do this on the stable release, but with the efforts of these guys, I'll have to do it sooner.
I apologize for the inconvenience.

Thanks! Looking forward to trying this tonight. Looks interesting. But what if no I don't want my Switch running a high CPU speed for a simple 2D game? Is there a toggle to turn this off, or does it reduce CPU clock automatically based on CPU load?

What is the default loader.kip, Micron or Hynix? I can see in Hekate I have Micron RAM.

 

[DedoGamingONE]

Would this be possible on erista though with lower core and gpu clocks?

 

[Asunix666]

Please post the necessary files, whitout atmosphere.

 

[mrcroket]

Wow this mod improve the gpu at near 800gflops so in theory a switch with this gpu power could move the same as ps4 but a 720p.

Are the included apps unmodified from source? Maybe put together a package of just the configs and instructions for installing the original open source packages.

Not that’s there’s any reason to doubt compiled code from a new user on their first post…

PS: Sweet photo man. Is one of them you?

better use this if you want max overclock : https://github.com/KazushiMe/Switch-OC-Suite

“Build

Now that’s what I’m talking about!

“Mariko Only“

Bummer

I wonder if OP package is Mariko only as well…seems pretty similar.

It say's mariko too in requirement so i think it's the same patch

a lot of this is extremely unnecessary and unsafe especially turning down fan speed with an overclock

 

[bbert]

wow unlimited video recording!!?
is it possible to get this feature alone without the other oc stuff?

 

[Cooler3D]

https://github.com/Cooler3D/Switch-OC-Suite

Correct. The modification is mostly based on customized sources of Switch-OC-Suite, Atmosphere (and other projects). I will add links and credentials to all used community stuff later.

The main idea of the modification is to give beginners the opportunity to touch the delights of overclocking. As simple as possible, including everything you need. Just unpack and use.

If you are an advanced user, then of course it is better for you not to rely on ready-made assemblies, but to assemble the necessary components yourself.

Mostly. But some of them was modified. Components from modification was tested several months before release in public. Including fan curve mod.

I mostly known on "that weird Russian forum" as Cooler3D.
I also plan to bring developments and modifications from my colleagues to GBAmp to make it easier for the English speaking community to have access to them.

I completely forgot that this meme is local to Russia. Its gist is that you are out of luck. In this case, we are talking about the fact that most likely the user has a memory from Hynix.

You can set freqs for any game, just open Tesla overlay, and try to find optimal clock speeds for you. Micron consoles must work fine with mod+first fix. Scheduler (Governor) for automatic freqs adjusting under the development.

 

[ZachyCatGames]

To those who want it on Erista, you really don't, on Erista the performance bump you get is negligible but the power usage and temp bump is massive.
Can't speak for Mariko, I don't have one.

Thanks. Like the other people that posted, I don't want to copy the whole archive to my SD, I tried that and it got stuck on boot at the Nintendo Logo. I reverted the changes. Then I tried KazushiMe files and it worked. Now I will find the files that are different in yours compared to KazushiMe and I will copy them to my SD card.

Thanks!

This not possible on normal switch?
