Nah the first install i did I had two mosfets outside of the cpu shield, the rest all glued inside the shield
When you install the mosfet outside the apu shield, and the glitch worked, did you use 30awg, around 10 cm length?

(Sorry lot of ask, i might replicate this. Its wonderful if i could do it. I will change my default mod as mosfet outside from the apu.)

The gnd of the mosfet, you take it from the cap, the chasis or somewhere else?

I've used the CPU ground(the small square in the right hand corner of the cpu), but it it a hard connection to make, I just use the chasis now

I have updated to firmware 2.74 ,Picofly keeps waking up my device ,so I can't completely shut down. I'm not sure if this is a common situation. My device is a Switch OLED.
The device will wake if you plug a usb cable in fyi

Check the pins inside the female flex connector

No, I didn’t insert a USB. It’s just battery-powered. After I turn off the power, the chip will work and wake up the device.

A question: Using two mosfets, is it necessary to bridge the ground of both to the point of the apu, or can I separate them and connect them independently to the same point?

The chip does not wake the console. This is a well known RTC auto power on after shutdown used by N system. Every Switch console automatically turns on after poweroff from the Horizon OS, even the unmodded ones.
The picofly firmware detects that and automatically shuts the system down after the successful glitch.

You can seperate them there is no harm, but you have to make sure good secure connection. Do not make cables too long or different sizes. Make it as short as possible and same size.

So, using the yellow way in the picture is ok?

I tried to soldering using the green example but I can't do it very well.

I personally don’t recommend using APU as ground point. Use APU shield instead.

Solder like purple lines. Yellow is more difficult

That squared is very difficult to solder. I am afraid you breaking something while doing it. Better just use chassis, simple and easy.
Ok, I`ll use shield as ground point. Thanks.

I can´t see any purple lines on the image I`ve attached. You mean same as Bad and Abal? Using APU shield as ground point?

BTW, Can I use APU shield too soldering the GND point of RP2040? In the past I modded one Lite and the ground point at the capacitor scares me a little bit hahaha

Yes you can use APU shield as ground point. You can also use TYPE-C connector on Lite console.

  • The Real Jdbye @ The Real Jdbye:
    the vram is one advantage when it comes to AI but ends up being slower even with that and really AI is the only use case that needs more than 12gb vram right now
  • Psionic Roshambo @ Psionic Roshambo:
    Interesting lol
  • Psionic Roshambo @ Psionic Roshambo:
    I think I watched a video where two games at 4K where eating just over 16GB of RAM and it's the one case where the 7900XT and XTX pulled ahead (minus RTX of course)
  • Psionic Roshambo @ Psionic Roshambo:
    So my opinion is that they could age a bit better in the future, and maybe AMD will continue improving them via drivers like they tend to do. No guarantee there but they have done it in the past. Just a feeling I have.
  • The Real Jdbye @ The Real Jdbye:
    cyberpunk at 4k without DLSS/fidelityfx *might* exceed 12gb
    +1
  • The Real Jdbye @ The Real Jdbye:
    but that game barely runs at native 4k
  • Psionic Roshambo @ Psionic Roshambo:
    I think it was some newer games and probably poorly optimized PS4 or PS5 ports
  • The Real Jdbye @ The Real Jdbye:
    they definitely will age better but i feel dlss might outweigh that since it looks about as good as native resolution and much less demanding
    +1
  • Psionic Roshambo @ Psionic Roshambo:
    When I played Cyberpunk on my old 2080 Ti it sucked lol
  • The Real Jdbye @ The Real Jdbye:
    AMD could introduce something comparable to DLSS but nvidia's got a lot more experience with that
  • The Real Jdbye @ The Real Jdbye:
    least amd 7xxx has tensor cores which the previous generations didn't so there is the potential for AI upscaling
  • Psionic Roshambo @ Psionic Roshambo:
    They have FSR or whatever it's called and yeah it's still not great
  • The Real Jdbye @ The Real Jdbye:
    so AMD seem to finally be starting to take AI seriously
  • Psionic Roshambo @ Psionic Roshambo:
    Oh yeah those new 8000 CPUs have AI cores built in that's interesting
  • Psionic Roshambo @ Psionic Roshambo:
    Maybe they plan on offloading to the CPU?
  • Psionic Roshambo @ Psionic Roshambo:
    Would be kinda cool to have the CPU and GPU working in random more
  • Psionic Roshambo @ Psionic Roshambo:
    Tandem even
  • The Real Jdbye @ The Real Jdbye:
    i think i heard of that, it's a good idea, shouldn't need a dedicated GPU just to run a LLM or video upscaling
  • The Real Jdbye @ The Real Jdbye:
    even the nvidia shield tv has AI video upscaling
  • The Real Jdbye @ The Real Jdbye:
    LLMs can be run on cpu anyway but it's quite slow
  • BakerMan @ BakerMan:
    Have you ever been beaten by a wet spaghetti noodle by your girlfriend because she has a twin sister, and you got confused and fucked her dad?
  • Psionic Roshambo @ Psionic Roshambo:
    I had a girlfriend who had a twin sister and they would mess with me constantly.... Until one chipped a tooth then finally I could tell them apart.... Lol
  • Psionic Roshambo @ Psionic Roshambo:
    They would have the same hair style the same clothes everything... Really messed with my head lol
  • Psionic Roshambo @ Psionic Roshambo:
    @The Real Jdbye, I could see AMD trying to pull off the CPU GPU tandem thing, would be a way to maybe close the gap a bit with Nvidia. Plus it would kinda put Nvidia at a future disadvantage since Nvidia can't make X86/64 CPUs? Intel and AMD licensing issues... I wonder how much that has held back innovation.
