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? what comes to your terminal?
Default Voltage and Clock:
- 1000MHz 1000mV
- 900MHz 950mV
- 750MHz 875mV
- 650MHz 850mV

- 300Mhz 750mV

I read somewhere the min. voltage is something like 750, so your uv at the low range has no effect.

Hi!
This is my stable config:
- 1200MHz 1050mV
- 1000MHz 975mV
- 900MHz 900mV
- 750MHz 800mV
- 650MHz 700mV
- 500MHz 600mV
- 300Mhz 500mV
kernel eternity 1.4

The chip in our beloved LG O2X cannot output voltages lower than 770 mV.. So assigning any UV-values below 770 mV is useless.
I myself am using Benee's VorkKernel:
1200 MHz - 1075 mV
1100 MHz - 1025 mV
1000 MHz - 925 mV
800 MHz - 825 mV
500 MHz - 775 mV
300 MHz - 770 mV

Hi,
I'm not an Optimus 2x owner, but a Motorola Xoom owner.
Luckily I'm one of them with a tegra 2 running stable on 1700mhz.
Now I'm playing around to get a lower voltage profile. My first try was interesting successful running [email protected]
so here I'll post my voltage table while trying around(so do not try it):
below 760 mhz removed, because of the same voltage
Freq @ Voltage @ Temp @ MFLOPS
0760mhz @ 0800mv @ 35.2°C @ 047.100 = stress stable (1.5 min)
0816mhz @ 0825mv @ 35.2°C @ 053.342 = stress stable (1.5 min)
0912mhz @ 0825mv @ 35.0°C @ 057.743 = stress stable (1.5 min)
1000mhz @ 0850mv @ 36.1°C @ 065.375 = stress stable (1.5 min)
1200mhz @ 0975mv @ 37.1°C @ 075.500 = stress stable (1.5 min)
1400mhz @ 1075mv @ 37.1°C @ 089.006 = stress stable (1.5 min)
1504mhz @ 1125mv @ 37.0°C @ 093.912 = stress stable (10 min)
1600mhz @ 1225mv @ 37.6°C @ 098.062 = stress stable (10 min)
1700mhz @ 1275mv @ 00.0°C @ 102.750 = stress unstable
legend:
death = caused a reboot
linpack stable = linpack gets max 1 inconsistent in 5 runs
stress (un)stable = stress tested + temp check
For the stresstests I'm using StabilityTest.
it is interesting, that linpack gets the best results when the cpu is running at the lower voltage limit.
but the most stable settings are the default settings, there also 1700mhz are working in the stress test stable

OC/UV settings

What are your OC/UV settings?
Thank's for the info!
Sent from my GT-P1000 using Tapatalk

Currently at:
Min: 100mhz
Max: 1200mhz
Cpu Govenor: Conservative
I/O: V(R)
Works great for me, no lags everything runs smoothly

I'm currently running:
Minimum: 100 Mhz
Maximum: 1300MHz
with the ondemand scheduler
and the sio I/O scheduler
All this is on Overcome Jupiter and I find it gives me enough power to keep things running smoothly but the battery is still great.
At the moment, I'm not Undervolting but I used to run it in a cascading scheme where at 1300 I would undervolt 125 and drop 25 each frequency step until at 800 MHz it was back at standard voltages. This improved my battery a bit but led to the occasional glitch etc.

Performance case:
Minimum: 200 Mhz (200 mhz -75mV, 400-1000mhz -50mV, 1200mhz -25mV, 1300-1500mV untouched)
Maximum: 1600MHz (overvolt +50mV)
ondemand\performance cpu governor
deadline I/O scheduler (looks pretty faster than sio)
Battery saving case:
Minimum: 100 Mhz (100-600mhz -75mV)
Maximum: 1000MHz (800-1000mhz -50mV)
with the powersave cpu governor
noop I/O scheduler
those settings are best as for me.
also if i need extreme speed i lock CPU @ 1600mhz or cut its scaling up to 1400-1600mhz (beacuse overheatings suck badly)
using modded Overcome 3.1.0

I used the performance settings above and so far so good. I'll post back if battery performance is any better.

[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

Post your cpu/gpu/ram voltages!

Hello guys!
I think that was a good idea to make a thread of our voltages.
This will help people who want to change CPU, GPU and RAM voltages.
(RAM & GPU only Werewolf kernel)
You know, this tipe of settings is avaiable only on costum kernel like kolk's, lauferstepperwolf's or iodak's.
So it's time to share your settings on trickster mod or tegra overclock!!! :thumbup:

CPU: -65 mV
all other Voltages: no effect
(CPU-variant 0, WerewolfJB kernel)

Frequency (MHz) - Voltage (mV)
1600 - 1150

1040 - 862
990 - 850
780 - 812
650 - 775
480 - 812
CPU Variant: 1
How the hell do you undervolt GPU and RAM?

werewolf kernel has the ability, using trickstermod

@someth1ng :I saw a setting for the gpu and the ram but I think that was my mistake.
today will correct first post and title!
btw: to find best configuration of voltages I need to undervolt by 10mV and test with quadrant if the phone is stable? and if it is stable undervolt again by 10 mV?
can anyone post default voltages?

Ahhh, makes sense because I'm on iodak's kernel. Better battery life.

-75 mV for cpu on iodak's kernel with variant 1. It looks stable also at - 100,but I think it's too much.

bumping thread, since many people uses iodak 9.5 on kitkat atm thought this thread would be useful,
Also I've undervolted for -122 mV on MPU on all freqs, did benchmarks etc. with this setup and looks stable so far, doing a stability test atm.Got variant 1

Hey guys, sorry for bumping an old thread. I just want to ask if any of you experienced freeze with just -10mV for MPU?
I'm currently on Stock V20A, with WerewolfJB v10, Ottoman's V2 script and SQLite.
I use Device Control (like one on NamelessROM) to change governors.
CPU Variant: 2
CPU Governor: Conservative
IO Scheduler: SIO
I use Conservative because my device gets hot pretty quickly on Interactive/SmartAssV2, like 70-80C after using at least 10-20mins. I get stutters in Conservative but it's manageable, and I don't go beyond 50C even with heavy use.
Knowing it won't do any harm with a little tweaking, I undervolt Interactive by -50mV, and my device would freeze in less than 10mins. On -25mV, it improved a bit but it froze after 30mins. So I thought, maybe -10mV would be perfect for me but then, after an hour, the device froze again (SetCPU's stress test lasted only for 2mins on -10mV).
Am I doing something wrong here? I can see that many of you UV'd your device @ -100mV and get a stable performance.

A7 2017 gpu governor or overclocking?

I found out that the gpu clock ranges from 343 - 962 MHz interactive
612mV gpu voltage
Is theres a way to overclock this?
