how does one get the offsets for the patches?

Was it equivalent to what is there currently?

Should be, I have tried the patch for Erista (1.3 beta) and it is working fine.
No release on the current Github page though.

tldr: search for known data.
I don't feel like writing an essay describing the entire process, heh.
But shit remains largely the same across firmware versions, I've ported my patches to all firmwares (+ 0.4.0 for lols), biggest change was probably in 5.x when they added support for mariko.

alright, thanks. My assumption was that I would look into the pcv sysmodule and get the offsets from there.
Can you extract firmware update files the same way you would extract game NSP's? they're both in the same format.

Yeah, if you have a bunch of firmware NCAs, you can search for a specific title using hactoolnet + grep/findstr

Code:

E:\Nintendo Switch\Firmwares\prod\12.0.3 (NintendoSDK Firmware for NX 12.0.3-1.0) (v805502996)>hactoolnet -t switchfs --listncas . | findstr 010000000000001A

feafbedd216b7c81e52cf03b6a6930af Meta       010000000000001A

Then extract it with

Code:

hactool(net) --exefsdir exefs whatever.nca

Does anyone know if the patches for Kazushime's OC work for newer versions of Atmosphere?

Unless someone has manually patched them from the source code, I am unsure they will exist. The repo has been taken down from GitHub.

One possibility is to manually patch and build the latest atmosphere and hekate yourself to remove HOS’s limits (Only safe for erista and mariko models, not v1 switches). Then, to take advantage of the higher clock speeds you would need to either build or source a modified version of sys-clk with new values to assign to apply higher clock speeds. Although this would be quite an involved process.

I'm using v1.0-5.17 on 0.19.4. Seems to be working the same as 19.1/19.2/19.3.

v1 is erista...?

Ah, I assumed erista was patched non mariko units. I definitely could be wrong though

All “v1”s are Erista, both patched and unpatched, the only difference is one of the OEM ipatches was replaced with a patch for the RCM bug in patched devices.
And CPU/GPU OC patches will kill both.

Also my ams patch (which is what the ams patch on their github was) should apply to modern AMS still unless they fucked smth up in it. The relevant files in ams haven’t been updated awhile.

Not sure if anyone cares but here's what I gathered from testing this weekend:
I think that these HOS bypass clocks are most likely not worth it for Erista users unless you are extremely into 60fps mods (where it doesn't help much IMO) and not care about how long your console will last you.

From my testing, the only game that I appreciated the higher CPU clock from (2091mhz) would be Minecraft in 4 player split-screen. (it even maxes out 2 cores at 100%) Most games don't need that high of a clock rate.
I was able to go down as low as 1225mv (stock is 1120mv?) on CPU for 2091mhz, going lower would decrease CPU speed.

Games that already run poorly with 921mhz GPU will not run any better on 998mhz. (it's maybe a 5% difference and going higher is potentially dangerous.)
+ my fan was much more active on 998 than it was on 921, which might be due to much additional voltage applied in the patch. (not sure where Kazushi got these voltage numbers from, haven't done any test with going lower in voltage.)

The biggest gains were from RAM overclocking, where 2131mhz really helped a lot with Bandwith-bottlenecked games like Minecraft, Hyrule Warriors AoC, Xenoblade 2. games in general load faster too.
Overvolting is needed in some (most?) cases, not sure how that affects the longevity of the console.
-
Mariko units might be a different story, as those are able to reach much higher clocks with less risk of bricking (due to lower power draw), but they sadly cannot overclock as much on RAM as overvolting RAM is not possible (yet?).

re: voltages
I've attached an image picturing voltages for a bunch of clocks on my Erista (and 2295MHz, which isn't pictured there, is 1400).
NOTE: Voltages may vary heavily based on the device's binning (as much as 100mV), mine probably has lower voltages than most as I have a good binning.

On Erista soft limits for CPU and GPU are 1227 and 1150 respectively, hard limit for CPU is 1400, hard limit for GPU I don't know.
GPU is way more complicated than CPU and requires very specific coefficients to work, there isn't really much you can do about the voltages you get there. Upping the max voltage is also much more difficult, which is why I haven't tested anything past 1075 in HOS.

Edit: And on Mariko soft limits for CPU and GPU are 1120 and 1050(?) respectively, hard limit for CPU is 1525 (You shouldn't go anywhere near that though kek), and I don't know for GPU.

How about emulation? Mainly Citra and Mupen64 with retroarch. I know some games play fine with safe clocks but other need a boost. I'm not done with my emuMMC backup yet so I cant test it myself for now.

Citra runs at 5x resolution on OoT with overclock using this solution

Glad to see that you've taken over

, I've been busy recently... anyway, I am adding two files: 'releases' page and the 'main' one (with README.md rendered) saved via the 'SingleFile' browser extension as .html (self-contained, tested in Chrome) - these are much more convenient to read than the jpg you've attached.

Feel free to also add these to your post.

Is overclocking the ram on erista v1 safe? is undervolting possible in stock clock?

Yes, ram is the only safe thing to overclock beyond binned clocks on Erista.
You can but I don’t give a shit enough to poke at it.

It's safe, just don't go overboard with the voltage, I've seen some people going up to 1.3V and 1.275V in the Discord server, no Idea what the safe limit is. CTCaer mentioned something about a maximum of 20%,on Samsung RAM, depending on your RAM specs that might be around 1.3V as your """max safe""", note that this is purely speculation. (But as always: do at your own risk, don't quote me on that and make your own decisions.)

Undervolting depends, when I undervolted on stock clock's I had lower performance than on stock voltage. Even lowering the voltage by just 20mv gave me a slight speed decrease, besides, the CPU is not "the hot part" of the board, the GPU is and I don't think we can undervolt that for now.
