but there isn’t really any benefit to doing so :P. and you may encounter stability(tm) issues
i doubt i would find stability issues when im not actually overclocking the system? just using default clocks

though i would agree, having 1 ghz would be more useful in horizon :)

ODNX01 and ODNX02 (and any other revisions probably) are binned for 1.7ghz CPU and 921mhz GPU.

oh so going over those frequenciess can give stability issues because that reason? maybe being binned to that frequencie is only a software lock and cause no issues? dunno rly but thx for the info :)

say, has anyone tried a ps2 emulator on this one?
if so then how well do they run and perform?
any reasonable framerates?

No. PCSX2 will not run on this. They specifically target 32bit x86. They don't even officially support 64bit x86. The Switch is too underpowered for PS2 emulation to work.

They were tested and confirmed to be stable at those speeds. You can force it to run faster (as seen with the 2ghz OC in v1.2), but it may or may not be stable.

False. Ps2 emulation would most likely work pretty good on the tegra x1. Just a matter of someone actually making an emulator. Ps2 on android is actually impressive considering it's stolen pcsx2 code that is not optimized.

No idea, seems driver is broken for you.
@bylaws is it possible to get gpu freq up to 1ghz too? so is like native tegra x1? i wanna melt my switch
Dolphin isn't gpu bound at 720p, 1ghz could totally cause battery issues.
Nothing. Still the same. Gonna try it with UHS-1 once I move the stuff from it.
Hmm, only other solution I can think of involves limiting sd speed... I'll give two images next version
Umm @bylaws is it possible to eventually fix the otg undocked?
Yes, when I feel like it

i get like 3 times the fps on the gpd win 2 for gamecube emulation than on the switch and the win 2 still strugles with some ps2 games


i rly doubt u would get playable speeds on the switch for ps2 emulation

It isnt turned on by default, but if enabled you should be able to
Code:
echo 0 | sudo tee /sys/kernel/tegra_cpufreq/overclock
and turn the overclock off?
Thx but, how can I disable This ONE? "
echo 2091000 | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq"?

--------------------- MERGED ---------------------------

"?
Edit: Nevermind, i got it, I ran echo 1785000 | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq

I'm 100% positive the switch is capable of ps2 emulation at playable speeds. My crappy phone is capable of playable speeds on certain games using Damon & Damon is just stolen pcsx2 code poorly optimized for arm chipsets.

maybe the switch will play ps2 games with damon when it will get android fully working with the new kernel :)
