Post your Glitch v14 live OC and step values

Now that we have a new way to overclock in v14 there are near unlimited variables to overclocking with this kernel. I've found a good balance of performance with 1300ghz step and live OC value of 121%. Let us know what has worked for you. You may include voltages as well.

I'm using reborn90's settings
200-1000; 110% live oc arm volt; 800/950/1100/1175 int volt; 1000/1000/1000/1025
Seems rather steady, I also recommend turning save on boot in settings of nstools before applying these settings just in case xD

I am on 100-1300 with 116% Live OC, haven't played with voltage yet but everything runs great.

I can't seem to get any live OC percentage stable and anything around 118% + automatically freezes and reboots.any suggestions?

Do you UV first then live oc? Or is it just stock voltages?

For the most part I just use stock voltages when playing around with live OC because I haven't found any voltages in threads that i'm sure are stable.

it depends on how far you phone can go, some can oc more then others but some less then others, I usually never go passed 1.2ghz ,I'd rather save battery.

Just my opinion, but since Android 4.0 relies so heavily on the hardware rendering capabilities of the phone you'd be better off to UNDERCLOCK the CPU to 800mHz, and apply the Live OC to say 125% and have an effective CPU speed of 1000mHz while increasing the GPU clock by the same amount. I've tried it and it works very well but I didn't stick with it long enough to see how it affected battery life. You will need to modify your voltages though. I was at 1250mV on the 800mHz step.

If anyone is interested in just using stock settings, i found this thread interesting:
http://forum.xda-developers.com/showthread.php?t=1424064

100-800 mhz, 125% live oc.

So how much of a change have you noticed from Stock kernel to Glitch. I tried OCing once.. and it froze.. and phone died.. and ended up having to wipe / re-flash. Probably user error though

Just wanted to say I accidentally OC'd to 1.4ghz with 110% LOC and man did this thing fly and didn't even crash.

I noticed I'm able to achieve higher stable oc (over 1500) using low leakage voltage and live oc of 116 or less. Without low leakage i can barely acheive 1400 oc at anything over 110 live oc. Never noticed this much difference in internal voltage stability in previous kernel version. I wonder what's changed?

-0.25mv / 1500Mhz gives more quadranet vs stock 1400 mhz and stock voltage

-0.25mv / 1500Mhz gives more quadranet vs stock 1400 mhz and stock voltage
how healthy to keep it this way? any risk go up to 1600Mhz?
on last Omega JB rom i went from 4000 to 5130 in quadrant using this OC.
Thanks!

Of course higher clocks gives vigher benchmarks. Uv doesn't affect unless you uv to the point that voltage can't keep cpu stable.

The question: 1500-1600 levels risky to CPU ?
UV lower is good to keep temp lower...

From my experience, undervolting offers no benefits at all. Temperature remains the same and battery seems to be worse when idling.

with no overclocking and with stock 4.1.1 li7 i have 6300 scores in Quadrant..... with overclocking to 1600 mhz i reached 6700... no sense to overclock it

Which rom you use ?

Learning time!
-UV provides stability, its not to save battery. Its such a miniscule amount of volatge it wont mess up battery life, but it will help stability of the CPU...
-And when you OC, you need to undertand that it doesnt stay at the max speed on all four cores all the time. It changes to fit the needs of the user.
I think the CPU can reach 2.0GHz easily, i mean my single core Captivate with a Hummingbird 1.0GHz ARM cortex-A8 could reach 1.92GHz and stay stable with -50mV UV.

Overclocking question

If I leave my phone Overclocked example 1.6 ghz as a daily driver, aka all the time, will I cut my cpu's life drastically? Will I damage my phone quickly? Were is the line when my phone is no longer stable and I couldn't use it as a daily driver?
Sent from my Nexus 4 using xda app-developers app

Each chip has its own tolerances as well as each user having their own load they put onto them. There's too many variables to give a number.
I wouldn't say "drastically" at that speed (1.6ghz) ...
but a shorter overall lifespan of the cpu is the cost of OC. Especially considering there's no way other than undervolting to control the extra temperature generated. And that's no where near having a heatsink and fan or liquid system as in OCing a pc.

I figured

[Q] Does underclocking and/or undervolting actually save battery

If anyone is using lower freq and/or undervolt, does it noticeably save battery?
If so, what freq and/or undervolt are you using.
Or if you have any other tips to save battery, would be much appreciated

They will have a slight effect on battery life, but not a huge one. It's almost not worth it.

Undervolting has small increase in battery. Main benefit of Undervolting is that it reduces the amount of heat generated.
Underclocking will also reduce heat but can actually decrease your battery life because it takes longer to perform tasks.
At idle speeds your phone is very efficient at saving power so by lowering the clock speed it takes longer with tasks and subsequently spends less time at idle where it's better at saving power

By how much is it safe to undervolt?

If the phone froze up or reboot its too much.

-100mv on all frequencies is usually fine for majority.
Note that some kernels will already be running at -100mv though

I run faux and UV at -100 never tried to go lower

Mulit-core hacks

So I have a very thought out question now I have a 4 core phone right? Well my battery life is below average and I was wondering if I had all my cores running at once would it balance out battery life? I just need some help from someone who knows about all this and are all cores mandatory?
Sent From My Liberated E970

You can select how many active cores are activated with trickster mod and (necessary!) a kernel that supports this.

I know how to and can with my kernel but I need to know if more cores are activated if the battery life will be better or worse
Sent from my Optimus G using XDA Premium HD app

I would definitely take a look in to what my batter usage is and how to control that before I worry about the cores. Just my two cents.
P.S. I am sorry but I believe the Multi-core in the title is spelled wrong.

More cores active would mean more processing power, and more processing power requires more energy(atleast on the same cpu), so disabling most of your cores would result in better battery life, maybe by a little bit though.

Hahaha I didn't realize it said mulit

useful topic

It seems to me that by disabling cores wont make a difference to your battery life, only to your performance. It doesn't matter if 2 cores work for 5 seconds or 1 core works for 10 seconds, it is practically the same power consumption

Play around
I would say download CPU-Z from the Play Store and look how much Cores are active and which clock they're at.
Then flash a custom Kernel, which lets you control the clock, govenor and how much cores are active, undervolting may increase your battery life too.
Play with the settings (PLEASE DO NOT RAMP UP THE CLOCKS or set the voltage to the lowest point you can, it may break your phone, stay reasonable, it's not my fault if your phone bricks) and look what's best for you.
Pro Tip: Take a look at the different govenors and look what they do. Google them!

I hope I could help you a little

Im using trickster mod and I know about all of this I studied up and have undervolted by 200 MV stable but I'm using the hotplug settings to 1:2 so not all 4 cores are active and I get almost two days on one charge!so I guess that does mean less cores use less power
