700mv minor overvolt :rofl2:
The default is 600mv. I don't think I'd call that minor especially when hekate doesn't let you go over 650mv. That's a huge increase

700 mv is not that much. It's not even enought to light up an LED, although it's a bit higher than spec, the chips will be fine with it, it's still a pretty low voltage

The comparison isn't valid because LEDs all have different voltage ratings just like RAM and other components. 700mv is plenty to light low power LEDs.


For reference 700mv is ~17% higher than the rated voltage. Even with 5-10% for tolerances it's still another 7% HIGHER than a very generous tolerance. It may well work, it may well last a long time, but it certainly wasn't designed for that and I don't see how it could be claimed "safe".

Higher RAM frequencies above 1600 have a chance of auto-corrupting the emuNAND on boot and also during games....

I think on boot is probably fine cause I think it might always boot with 1600mhz to prevent booting problems, but I really have no clue if they changed it... But after loading the high memory OC, yeah everything is possible.

And what if I told you than NO actual cases of FS corruption were found during testing? Remember, 4IFIR uses lots of custom optimizations and even a custom build of Hekate called 4ekate

I have no Switch experience, but on PC, it's unlikely that you will corrupt the system too because it will crash most likely before it and windows will most likely also auto-protect it self by throwing a BSOD...

But that is all good until.... IT HAPPENS :D (even if 1 in a million or more).

On a friend's PC for example I told him to try just 1 step higher frequency without touching voltages and timings, just plug-n-play, all was stable and fine until on 1 3D app somehow it was running massively low performance and he had to go back with stock frequency while all other games and apps he uses was fine.

All kinds of random stuff can happen for sure, though surely I could OC his ram higher if I was there my self increasing voltages, CPU mem controller voltage and messing with timmings, but it was just a quick easy fast OC since he has 0 experience...

Windows and Linux file systems have very robust failure handling mechanisms to prevent corruption. FAT basted file systems do not.

I don't like Linux but saved my bacon when 1 CPU core burned lol

Windows just BSOD and restarted and then was on a constant restart boot loop, I went for the installation thinking my windows went bad and same so I started thinking damn something is really bad, tried XP it just BSOD...

Until I tried Linux and told me CPU hardware problem :sad:

Gladly after many time trying to fix it I thought on reducing cores to 1 and boom windows boots, then tried 2 cores, then 3 and all was fine, just 4 cores doesn't LOL

ps: But this is not to scary anyone from OC, it's a 2011 I7 2600K with max turbo to 3.8ghz and was heavily used for 11 years at 4.9ghz around 1.4v so yeah, they will just not die and since the 90's and many hundreds of PC's I never seen a bad CPU in real life, only read about it, it's the first ever true CPU hardware failure I have seen in real life and had to be on my PC :toot: (now boards, PSU's, HDD's and GPU's there's always a huge cemetry of dead ones)...

The switch doesn't really have anything like throwing a BSOD to save itself. It will essentially corrupt until it can no longer boot anymore.

20V can barely power this backlight, lets throw it into a fan.

Well it kinda has when it messes some value that atmosphere doesn't like and throws a error :D

But yeah it's not like windows which has a insane amount of "stability patches" built-in which almost everything will trigger a BSOD according to them to prevent further damage :toot:

lol you dont know how much current flowing to that chip, not voltage burned things, only how high current is
