Tegra OC/UV Voltage

Hello, I'm tried, with the OC and UV of my terminal, I managed to get these results:
- 1200MHz 1025mV
- 1000MHz 925mV
- 900MHz 875mV
- 750MHz 800mV
- 650MHz 775mV
- 500MHz 725mV
- 300Mhz 675mV
My terminal is stable, tested after 500 sec of stress cpu, but also comes to 63° in the test, what is the maximum temperature stability for Tegra?
What do you think? I should remove the OC and just leave the UV?
Default Voltage and Clock:
- 1000MHz 1000mV
- 900MHz 950mV
- 750MHz 875mV
- 650MHz 850mV
- 500MHz 800mV
- 300Mhz 750mV

How do you undervolt the unit? Thanks.

[Q] Overclocking the Tab

Hey does someone know the overclock configuration that was posted on the Overcome page once? I'm running on Overcome 4.1 with the belonging Kernel which allows me to get to 1.6ghz (theoretically) and I'd like to overclock to 1.2ghz.
I'd be very grateful if you could help me
Edit: I found this http://forum.xda-developers.com/showthread.php?t=1036020 but does this guide also apply to Overcome 4.1?

Just use Voltage Control or SetCPU. It's really not that hard at all. Just be careful with your voltages-overvolting will eat your battery more but may allow you to reach higher frequencies, and undervolting may get you better battery life but may make your tab unstable.
As a reference, I have my Tab running at 100-1.4 with smartassv2 and stock voltages on the Overcome 4.0 kernel.

thanks ;-) but which sheduler do you use?
for those who also have problems with overclocking and for
the newbies (like me =-D) I found this page which describes the usage of shedulers
and governors http://forum.xda-developers.com/showthread.php?p=19846297

IO Scheduler: CFQ
Governor: Smartassv2
At least that's what I use on my phone. I just left everything alone on my tab.

thanks, you helped me a lot ;-)
I'm using Voltage Control on 1.3ghz with stock voltages on smartassv2 and deadline and it runs pretty stable

Thanks, useful tip for me too.

I use SetCPU
OC max 1.3GHz, min 100MHz
-75mV from 100Mhz --> 1.0GHz and then -50 from 1.0GHz to 1.3GHz
PLUS various profiles to set max to 800MHz whilst screen off etc etc

that's exactly the same that I did =-D=-D=-D

That's pretty much what I have. OP, sorry I couldn't answer your PM, my tab is currently bricked and I haven't had the chance to recover it.

yea I have time =-D that's not so important, just make sure your tab runs again ;-)

This is what worked for me as well, just don't check"set at boot" option till you've tried that speed for a few days and you config proves stable.

Haha, I did check that option when I foolishly set the OC max to 1.6GHz
...I was just able to uninstall between one of the many lopping reboots
Anyway all, sorted now. In fact I have reverted to stock voltage for 1GHz up to 1.3GHz because playing Trial Xtreme2 would cause a reboot when I'd exited the game - seem's all ok now *touches wood*

[Q] Which is the most recommended Governor

I'm using emanoN V4 with No-Frills, and since CM7.1 with SetCPU, I always used 'ondemand' as Governor.
But reading other posts on other devices forums about this, some people say SmartassV2 is the best...
So, as each device is different (specially by the ARM version and manufacturer), I decided to begin this conversation here, and listen to what people with the same device as me has to say about it.
So which Governor do you consider the best for SGM?

Im using cm7.2, setting at nofrilis Governor : SavagedZen io : sio and undervolt at cm setting, give more battery life.
Sory for bad english

sio if u need less laggy n smooth

Thanks for the reply, but as I can see on No-Frills, sio is th I/O Scheduler, that is already set. I'm asking here about the Governor.

Ondemand and set noop
Sent from my GT-S5570 using xda premium

on emanonV4 i use Smartassv2 nd i/o noop

I see that people are very divided between ondemand and SmartassV2.
Now with sio and noop as I/O Scheduler.
Anyone else would like to share?

i will say ondemand because cpu will be set at lowest frequency and when you need it it will set at higher frquency which will save your battery and if you want performance then no lag will be good

The principle of the ondemand governor I'd already figured out (and actually didn't like it, very rough).
I would like to hear more about the principle of the SmartassV2, whereas since this morning I'm using SmartassV2 + noop and I noticed my SGM way smoother than with ondemand + sio.
Now is wait and see if the battery is sucked more.

smartassV2 is a re-working of the original smartass governor, it allows for the CPU to scale through all frequencies from the lowest you set to the highest, based on the load occuring. Basically it scales CPU based on realtime needs of the system, saV2 supposedly incorporates some more agressive settings for screen off, and I believe quicker scaling than the original smartass.

Thanks a lot, man! And now I think that I had made my choice:
Governor: SmartassV2
I/O Scheduler: noop
Highly recommended!

how i configure CastagnaKernel OV for have max performance

how i configure CastagnaKernel OV for have max performance without trasform in cheese my cpu? what the governor? the i/o scheduler and the processor mhz?
Sorry for my bad english,but i am an ignorant

OV? Over-volt? do you mean OC? Overclock or UV? Undervolt
smartassV2/SIO (personal favourites)
245mhz/1800mhz (so default settings)
And I think you can better post this in the topic itself, and you will never turn your cpu into cheese, i once ran a benchmark at 2.016Ghz, and it just turned off

I remembered the cranium kernel at 2016 mhz..it became really hot...
Ondemand( little bit tweaked) 368 1804 sio...that s perfect
Q.D.E.

It would be better if you post this on kernel's thread I think there is no need to made a new post about that and sorry but and I'm not trying to be disrespectful. however you can use smartassv2 245-1800mhz that's a good choice.

the combination of default: lulzactive + sio is very performant (CFS version)
or you can try the governor lagfree
if you want the best reactivity using the BFS kernel version,
but is less multitasking

[Q] cpu speed?

what are the best settings for
1)overclocking: which governer should i use and what should i set as min. and max. cpu frequency to overclock
SAFELY.
2)same for underclocking.
also suppose i wish to set cpu frequency at 700Mhz max. can i also set 700 as min.?or is there a problem with that?

1) max- 729mhz, min- 320mhz, smartassV2, sio.
2) max- 480mhz,min- 245mhz, ondemand, deadline.
No, you can't because mini's processor's default max is 600mhz and keeping (forcing) it to min. 701mhz will probably ruin your processor so stay away from high min. frequencies.... Happy OC....

so basically my min freq should not go above 600mhz...?

min frequency should not go above 200mhz
if you will set min frequency as 700 your mobile may reboot
and you can't oc stock rom, you will need to have custom rom like emanon

If you OC a lot then the camera might not work also.
just check all the things before doing OC
