And board limit is 18W on v1. This is from the guy who makes hekate and did hardware research.

There might be a difference between them but for the sake of this discussion the difference is irrelevant. They pretty much mean the same thing.
Thats what i mean, so its the same thing, alright! Hey, thanks!

So many of us have been using OC for years with no issues, you're overthinking this
Better to overthink and be worried, it prevents me from doing stupid things. than to "trow darts in a dark" and brick or damage my switch, which by the way, i cant afford again. So yeah....
But that's what these forums are for anyway. To discuss and overthink lol

It's the main reason I hacked my Switch. It's such a useful feature, especially for graphics whores like me.
I'm more of a performance whore, and graphics imo should be workable and if can, sharp.

I have an original day one switch and have been using sys-clk since it was released and no issues so far and also without changing the paste. For reference, i mostly use sys-clk for emulators but for some more demanding emulators i use the highest settings for OC, both dock and handheld. Still no issues to this day, and battery still giving me between 2-4hrs depending on how demanding the emulator is.

I hadn't seen anyone said they brick their switch with OC so it should be pretty safe. Or you can just ask if anyone here had broke their switch because OC and see it for yourself.

How about negatives of increasing memory speed to a maximum?
There are none. Unless you go above 1.6ghz

HOW would i know empirically tell if switch is at full load and where to stop, etc, so i don't just guess...?


Again, how should i know the power draw so i can act acordingly?
For the first one, use the status monitor overlay. For the second one the answer is essentially, you don't, not without external meters.
I have V1 Switch, never done that, but it works really nice and quiet/cool. I mean is 47 ok temperature for Doom Eternal?
I meantion that game since i presume its the one that stress the system the most. Byt he way is 60fps mod stressing the system also? I mean not overclocking, just having the mod and leaving fps to fluctuate.


So that means that switch can handle what i do, since you mention higher values than i intend to use.


I had a hard time following all of that but i think i understood.

Well since i play handheld/no charger, i mostly just set GPU at 460 Mhz and be done with it, since ether that does the trick, or i think it makes FPS more stable.

So what do you think about that? Just the GPU at 460 Mhz?
For V1 switch thats actually decent. Without a charger 460MHz is fine.
Why quotations? Is it fine or not fine?

What does memory do exactly in practical sense, what will i see on a screen differently if i increase it?
Quotations because it does come close to 18W, but not exactly and i've never seen it go higher than around 13-16W.
Memory also works as VRAM in this console, and increasing it means the GPU/CPU get access to data faster which means performance is increased all around.

The 20nm transistor models are less energy efficient so they generate more heat while running and draw more power. Staying within the 1.785 GHz and 921 MHz range is safe. Going over it might not be.
1.785 with 921 is """"""fine""""""" but very not ideal.

I would not go maximum everything but slight to moderate overclocks are fine. To summarize earlier posts the SoC is designed for these clocks but the power circuit on the Switch is not (18W limit). So as long as you don't max everything and the cooling is sufficient it's safe.

Well ststus monitor shows only cpu/gpu load, not the power load in wats.

For the second one the answer is essentially, you don't, not without external meters.
I see... thanks.

For V1 switch thats actually decent. Without a charger 460MHz is fine.
The difference 460Mhz increase on GPU makes for night and day in, for example, pacman repack, and 400 something p, cant remember, but picture looks decent and its super stable compared to no 480Mhz. It's good to know its fine. Switch gets really warm on the back though...not hot, just really warm. Its winter anyway so.... lol

Quotations because it does come close to 18W, but not exactly and i've never seen it go higher than around 13-16W.
Memory also works as VRAM in this console, and increasing it means the GPU/CPU get access to data faster which means performance is increased all around.
Ohh get it now. But in practice i only ever saw benefits (from games i tested) from increasing only the GPU to maximum alowed in handheld which is 480Mhz.
Whenever i increase the ram or cpu i see no difference at all. So GPU and some mods like lowering the resolution effects etc... Thats why i was curious as to what that does exactly. But perhaps some game will utilize idk.

1.785 with 921 is """"""fine""""""" but very not ideal.
I dont even go that high, i mean i cant, its limited in handheld. SO i guess you can take off quotation marks from fine haha :D

I hadn't seen anyone said they brick their switch with OC so it should be pretty safe. Or you can just ask if anyone here had broke their switch because OC and see it for yourself.
Well not brick, afaik thats a software thing, but i mean from exposing it to extreme heat and components dying or glitching out cause of OC.

By the way, i saw 2 people in the poll clicking "yes" up there...
It would be nice if they can be more specific here in the comments as to how it happened though.

I have an original day one switch and have been using sys-clk since it was released and no issues so far and also without changing the paste. For reference, i mostly use sys-clk for emulators but for some more demanding emulators i use the highest settings for OC, both dock and handheld. Still no issues to this day, and battery still giving me between 2-4hrs depending on how demanding the emulator is.
Im curious... can you please be more specific, what emulator, games, what clocks etc... ?

Its very dependent on silicon lottery and what manufacturer made your DRAM chips but generally speaking, above 1.6ghz has no downsides until your dram chips cant handle the frequency you set them to or the timings are too fast for them. If you cross that threshold depending on by how much, the two extremes are literally nothing happens, or the console crashes on boot. The only time i've seen a console crash on boot is when I set a badly binned console to 2.131ghz without overvolting the dram lines. Essentially going higher will have the exact same benefits, except its a more of at your own risk type thing. The biggest issue however is the risk of SD or NAND corruption, which is why whenever you push DRAM above 1.6ghz, a nand backup is very strongly recommended.

Yeah i do have a NAND backup when i hacked my Switch, i followed the guide on switch hack website.
I keep all my NAND's on one place for exact reason, and ocasional SD content backup, excluding "folder with installed games, that one is huge and i can install later on again.
Hmm...thats interesting, thanks for sharing the info with me, its nice to know how tech work so i have idea of what to expect realistically and what to do in certain cases on my own.

Hey, i noticed something weird in games, i was wondering if you can explain it to me.
sys-clk.... so when i open it up, i always see 307Mhz when its set to default, or turned off, and so say game has unstable FPS, skips a bit, for example klonoa, and when i actually choose GPU option to that same freaquency 307Mhz the game gets way more stable.
Like...i dont get it, i litearlly changed nothing except setting the same freaquency as it was by default. what gives?

I mean id understand if frequency fluctuate and setting it to 307 actually locks it at that, but i never saw any fluctuations in numbers when it was default, id say it was stable on default by looking at monitor, but when i SET IT to same frequency it gets better...like....why?

About the OC 1785mhz on CPU with 460mhz on GPU won't do much in the majority of games...

You can use StatusMonitor to see what the games need more, what has heavier use, just putting the CPU on 9999999mhz wouldn't do much if the game is GPU capped.

An example to CPU is my I7 2600K at 4.9ghz, 1 core burned after 11 years of heavy use but still worked by disabling 1 core making into a 3 core 4.9 ghz and in most games barely made a difference. In fact I went for a used 8700K which is just miles better and the performance is almost the same on almost games because my RX580 GPU just don't have enough juice...

Ram is by default a big bottleneck in Switch generally speaking and the higher clocks you go with the memory also tend to lower GPU usage which helps leaving more GPU power available...
I use and recommend Thermal Grizzly Kryonaut. Some people recommend arctic silver which I haven't tried myself.

Then it's a 20nm transistor model. I used one with maximum overclock settings for a few years and played some games which struggle performance wise like Hyrule Warriors: Age of Calamity, pushing the hardware to its limits. It still works just fine. Just don't try going over the 1.785GHz and 921MHz limits (it is possible but I'm not sure how) on it.
I used Kryonaut but can't say I like it, MX4 is so much easier to handle...

AS5 I don't recommend because it's electrically capacitive despite not being conductive with time it might still be capable of shorting.

Define "max everything out"?

So as i understood, its not the temperature but the power load on the board?

Guys, I tried Sonic Colors with 60fps cheat, and sys-clk at:

CPU - 1224 Mhz
GPU - 460 Mhz
MEMORY - 1331 Mhz

In handheld mode, no charger, it gives me pretty consistent 60FPS (drops here and there) is this to much power load on the board in your opinion?

P.S. do you know why my cheat is unloading every time i exit the game?
I need to reaply it every time i play.

I'm no expert but that's barely an OC so should be more than fine...

However you can check if the game doesn't get anywhere close to 100% on either the GPU or CPU you can probably drop the one that never maxes out and probably will have very similar performance while giving a few more battery life...

Also 1600mhz on the mem might help more while not making much power consumption difference compared to changing CPU\GPU clocks.

it should be like that or it shouldnt?
Depends upon what you want. The explanation is right above the line I highlighted. The default is 0. You probably want 1 but read through the comments in the file to be sure.

If you don’t have that file you can make one by copying the template in /atmosphere/config_templates/

while you are at it you should probably uncommented and change dmnt_cheats_enabled_by_default section right above it too. It all depends upon how you want cheats to behave.

I want cheats, that i activated, to stay active every time i start the game, till i decide to turn them off again.

What is "uncommented"?
The answer to that is above on Binkinator image... To uncomment is the lines you want to change its respective function you remove the ";" so that the line is active with the setting you have set for it...

As you can check the picture he has done all the work for you, you can check that both settings related to cheats in the picture already have no ";" in the beginning so they are active and the values are already setup for what you want.
