Tegra OC/UV Voltage

[Hell_97]

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
- 500MHz 800mV
- 300Mhz 750mV

PS: I have already started a topic in general optimus 2x forum, but I think here is on the proper

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

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

oh yeah!, you have inspired me, here's my new configuration:

Great! you are lucky!

Great! you are lucky!

1400Mhz stress test gives me 49º

1400Mhz stress test gives me 49º

Sorry but can you proof it?! Nearly all of us got more than 60°C with 1300MHz so I can't really believe it.

you will believe
here is a video with my temps with 1400mhz : http://www.youtube.com/watch?v=H5zOYXK3CoE
the cpu temp started at 47ºC

 

[K.D.M.]

Running max 1.2ghz on 1050Mv

Its stable and cpu temp is between 40 and 50 degrees.

try 1.2ghz at 1000mv

Ive used your readings now. Lets see how it does

My phone crashes at this voltage, the maximum for me is 1200MHz 1025mV.

Same here but 1100Mv @ 1.4ghz works good. Quadrent score of 4205

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
