Hardware Switch Suddenly Gone Extremely Slow

[Jackofall]

Within the last hour my switch has gone extremely slow, both in Sysnand and CF. It struggled to load a game at all, and when it does it's like 20x longer. Even certain system settings and users take a while to load. Closing a game takes much longer to do too.

Anyone have any idea why this may be? Appreciate any help or theory.

First thought would be thermal throttling? No Data loss/corruption happening? Could also be your SD card failing if it's having issues reading/writting.

Have you tried and reboot payload? Have you tested if your micro SD card is faulty/fake?

I've tested it at under 35 C after a 20 min rest and that hasn't helped. Also tried booting up the console entirely without an SD card, and it was still just as slow.The SD card is definitely legit and it's been fine for about a month so far, but I believe the fact it's still slow without the SD card should be rule out the SD card?

Mem failing maybe. Hard power off let it drain. Boot again.

This might sound like a dumb question, but by that you mean I should just leave it until the power reaches 0% and dies? No other steps?

Yeah that rules out the SD card it self, looks like it's not throttling either.

It makes me think hardware failure like Canna, was suggesting. Although maybe the NAND itself is causing issues? The fact it is slow to process commands seems like its getting stuck in a loop until it times out and moves on.

I think it's highly likely it's a NAND issue from the little I know, although I've done nothing to effect it over the last few days. I think I'll try letting the battery die entirely like Canna was suggesting for now.. before looking at more extreme options.

From google searches though not many people seem to have had my problem, so it's extra concerning

Also one extra thing. I just did a test, it took about 10 minutes to load into Animal Crossing, but once in the game was running smoothing, up until saving and closing and then it took about 10 minutes ago. So it's definitively something to do with how it's handling memory

Try replacing the eMMC board. You can make backups using Hekate.

Switch doesn't thermal throttle.

Draining was to take all power out of the system, then boot. But hey was thinking the emmc myself, very unusual for this to behave in this way..

But here is your most important option right now as mentioned.

Backup your console fully right now to save you trust me. If the emmc is dying and u dont backup you have paperweight without backup..

Backup Biskeys/system keys. > with LockPickRCM Payload.
Backup rawnand (emmc) > with Hekate
Backup Boot 0 > with Hekate
Backup Boot 1 > with Hekate
Please backup all of the mentioned above. and make sure you have solid backups and even copy of the backups..

Replacement modules (Emmc Modules can be found quite easily online)
You will need to Format correctly, Use Gpt Restore payload to CorrectlySet this, and then should be able to run hekate to restore nand. May use hacdiskmount to check partitions/structure and biskeys are linked.

I wish you goodluck. NOW BACK THAT CONSOLE UP!~!!


Edit: Just a thought, you never overclocked or underclocked did you ? That i think is held on the SD card in a config, try erase sd card and install just the cfw on it. And see if its better.
If u did not or it does not work then yes its probally the Emmc, Or Ram

I have the same issue now.
I tried installing an update with Tinfoil USB install. I usually got ~30MB/s, now it only was 1-2MB/s and falling. I benchmarked the SD card in hekate, that was all good. Now I try to boot to atmosphere and I'm stuck at the switch logo. (I restarted before, that took also a pretty long time, but now I'm stuck. )

Starting Homebrew was also really slow.
I thought it's the SD card. But I don't know now...




Edit: It's the MicroSD. I tried another and it works again as it should.
I tried transfer the atmosphere folder to my PC and this was painly slow. Holy moly. Sandisk has a 5 year warranty if I'm correct. This thing was expensive. 400GB...
