Undervolting/overvolting?

Does any ROM for our old GT540 support undervolting/overvolting?
Thanks!

no -volting.
its something different and for saving some battery juice or extra power.
many other (newer) phones/kernels support it.

if you know how overclockers clock their pc-s , then you should know about volt-mods/overvolting (vdimm,vdroop and etc.)

i think the only "undervolting" our phone can do is change the stock frecuency from 245 to 122 lower is unstable....up is 806 some people a little more or a little less...thast regarding the cpu frecuency in terms of Voltage i think is more than imposible due to inestability.

here is full overview of overvolting and so. : link
but shortly:
overvolting gives more voltage to hardware (cpu in this case) .
more voltage=more overclock , but also alot more heat.
undervolting decreases voltage of cpu, to save battery juice for longer time, but instability occurs @ same clock.
(need to lower cpu clock for more stability).
and also cpu is cooler.

Cpu

Hey,
Cpu spy and setCPU show that my N4 only uses the minimum freq and highest possible.
Does this happens to all?
Settings can be found on my signature

Theres a bit usage on the other freq, but nothing compared to min and max

Yes, it's because of the Franco kernel. looks good!

Yes that is normal. Min and max are used the most.

[Q] i9500 verylow benchmark and perfomance cpu float problem

hey my i9500 has very liw benchmark and hit only 19000 on antutu benchmark
im using phonix rom v4 plus presus v5 kernel
no overclocking has been perfomed and settings are set to their default
according to my screenshot from benchmark results, my cpu float point is lower than regular and I dont know why
plus ram memory hits very low score while I have only 0.9gb ram under use out of my 1.8gb

This is my benchmark using Omega v8 and latest perseus v5. All is well. Maybe your phone is too hot and cpu starting to throttling.

Can u plz tell me how measure or monitor if the CPU is throttling??? How can it be avoided???
Btw, I have Omega 9 with Perseus 5...
Thanks
Sent from my GT-I9500 (Hassan Khalid Malik) using xda premium

you can use setcpu to monitor (set the min and max clock same as the one in stweaks) if you set e.g. 1700mhz at some point (if cpu start throttling) the clock will stuck at 1400mhz, or 1200mhz depending how hot is your phone, It simply can't avoided as far as I know, if you want to make a benchmark, cool down your phone first

As I already said, I had never ovrrclocked my device and never changed any settings.. cpu is set on 16000mhz as default. So I dont know what u want why using another applications

[DISCUSSION]Governors and Schelduers

Okay,so i made this thread so that development thread become less spammed with your questions.
Please,share your opinions here and ask questions,someone will answer you,and share your screenshots of battery life.
I personally use PegasusQ+VR,it gives great performance and good battery life.
My second choice would be Abyssplug+SIO,especcialy for the hotplug feature.
(In case you dont know what Hotplug is,its the feature that turns off the second core when your phone is not in use.)
I cant decide wich is better,tommorow ill test Hotplug+sio,and ill post screenshots of both tommorow.
Please,ask any questions here,dont spam Benz's threads.
Thank you

OnDemand + CFQ (Like in stock ROM) the only way that don´t dry my battery.

With that combination my phone is slow like hell..have you tried those that i wrote.

Hi, can you tell me the best combination of governors to use. I'm using latest cm
10.1 maclaw build with hotplug and noop, but i think CPU its not sleeping cause i loose about 5% battery in 2hours withought using my fone at all. Thanks
Sent from my GT-I8190 using xda app-developers app ?

Hotplug governor is indeed a joke, at least in Maclaw's CM (not surprised). There is no way to set it up for low battery drain /and/ reasonably smooth functionality. Right now I am using Ondemand + CFQ while playing with the powersave bias and up threshold parameters. The only thing I wish I had from Maclaw/Benz's kernel is the vr/sio schedulers.

You have VR and sio schelduer in Benz's kernel,and Abyssplug governor with real hotpulg feature,when you dont use the phone cpu shuts down one core and the remaining core runs on 200Mhz and 1% usage.

I would gladly use that kernel if it didn't have the dirty flickering fix. And if it didn't require CM10.1 reboot edition.
Also, when I was on CM i ran a logcat with hotplug activated. The second core would often reactivate even if the phone wasn't doing anything, with the screen turned off, then soon turn off and after a few seconds repeat the process. Maybe this phone really needs the core.

What flicketing fix? I got no flickering on the latest Maclaws cm and benzs kernel..and it shuts down the core,you can see with system monitor when your screen is on..dunno for screen off,but i get like 1% drained for a hour with screen off

The 63 fps refresh rate, which "fixes" the UI flickering.
And yes, I saw the second core turning off myself. However, I am not sure if it keeps being off enough time.

Well in maclaws rom i dont have flickering,but in olivers i had. I dont know,i got decent battery life. Not good as stock,but its ok

Which is more battery friendly? Abyssplug or Pegasusq?

Read this. It will help you to decide which is the best for your needs:good::good:

Pegasusq said to have hotplugging but doesnt seem to work with screen on

Based on what I read, my best guess would be Abyssplug. I'll run some tests and will post my results.

Yes, it only turn off one core when the screen off. I'm testing pegasusq + sio

For the next days, I'll be on abyssplug + sio.

And what exactly is so wrong with 63 fps refresh rate? Will your screen fry because of it? No it won't because it can't. Will your phone explode while being used? No it won't because it can't. What's the issue here then? Tell me.

Have you considered the battery drain implications? The battery is weak enough as it is, a higher than normal refresh rate only wastes more GPU power thus more battery.

Undervolting

Anyone who undervolted his g2 ?
How low can we go ?
Sent from my LG-D802 using xda app-developers app

Very good question.
I hope some guys will reply who have already undervolted.
My max cpu frequency is 1190 MHz.
I don't think you need more speed on 4.2.2 (actually i'm on stock rom).

Gonna depend on soc binning for your device

My soc binning is 4 and I'm able to maintain stable undervolt by 50 mv (2.26 ghz @ 975 mv I think)

-62.5 here, I'm sure I can do -75 ( done it before) but it get micro lag, so I go to -62.5 works fine, nice and cool.

-100

I'd like to hear more about this! At stock settings my phone overheats and throttles badly. Been testing different voltages and at the moment I'm down five -12,5mV steps @ 962,5mV. Better temperatures and better performance due to less throttling.

I wish I had a rooted phone to do that

Where can you find the SOC binning value?
Edit: Hey looks like I found it
You can see the binning of your SoC in the last_kmsg located in /proc/last_kmsg.
You can also found it in /sys/devices/system/soc0 and search for pvs_bin and speed_bin or /d/acpuclk.
