I'm sure I'm not the only person but changing the clock speed/voltages is pretty damned confusing, voltages specifically. I never saw the point to overclocking(not yet at least, nothing really needs it) but lowering the voltages to save battery life is something I'm really into I just don't get how these voltages work at all.
Could someone post a quick walkthrough on it? I don't need your exact settings since I know it varies from person to person but a guide would be nice. I can change the clock speed, it's pretty simple and I used VControl to modify the speeds to 800mhz in both advanced & general but nothing else. Voltages scare me.
Just play around with it. The worst you can do is freeze the phone, nothing a hold of the power + volume up can't fix.
I recommend starting at -25 across the board and increasing slowly until you get a freeze so you can find the best balance between stability and battery savings for your phone.

As long as you don't OVERvolt your phone your hardware will be fine, although this isn't an issue since only VControl Extreme overvolts. Worst case scenario: your phone reboots because it doesn't like you taking away its power juice.
On stock clocks (100-1000 mhz) my phone can do -100 mV, anything above that -50. YMMV however, even "identical" processors have different tastes, ie one will take a beating while another is super fragile.

How would this work?
800mhz -50v
600mhz -50v
400mhz -75v
200mhz -75v
Would that save more battery or should I reverse the voltages? I don't get how voltages work exactly, that was my main question

-75 means that it takes 75 mv off of the stock voltage setting. That should work, assuming your processor accepts that much under.

Yeah everything is running fine, quadrant scores of 900 with ext4 begs to differ.. lol. Will overclocking drain more battery? I'd assume it would only affect battery when I'm using an intensive app like the browser that would actually utilize the higher CPU speed.

It'll stay at the lower settings until an app demands processing power. You will see a slight battery hit but a performance increase.
EDIT: I got 1224 @ 800 mhz.
EDIT: 2100 @1400 mhz. So you can see the performance changes drastically.

Appreciate all the answers but this was what I really needed, I wasn't sure if I needed to increase or decrease the voltage as the clock speed changed.
Still, thanks to everyone for the information.
1300 - 0 conservative
1000-25
800 - 50
400 - 75
200 -100
100 - 125
Still experimenting. Next charge I will try another governor. Also might try dropping the voltage more on 400 and 800 steps.

That's some mega voltage drops for 200-100mhz! I'm assuming that would just save some battery life when your phone is idle because I can't imagine any app only using 100mhz.
I am trying -75 mV across the board on stock voltages. No issues so far. Is there any reason to bump the higher speeds up in voltages? Ran a quadrant and I'm still scoring the same as before undervolting.

Voltages have nothing to do with performance. It's all about clockspeed.

I am not 100% sure, but I think the bottom steps are similar to PBJ. The only downside I used to get with UV the fascinate that low was that it would either not wake up from sleep sometimes, or calls and texts wouldn't come through unless/until the phone was woken up. Phone doesn't use much power when sleeping, but it is difficult to curb with 4G on.
This phone, in my experience thus far compared to the fascinate, can be OC'd way higher for me and be stable, and can also be undervolted across the board more successfully.
Governors I know nothing about, but have been doing some reading. Still not 100% what each one does. I usually don't OC, but it has been outstanding on this phone thus far.
I use noop and ondemand.

noop is the IO scheduler and ondemand is the governor. Imoseyon did some tweaking to ondemand, so that's why I use that versus other governors. I find that noop is more stable for me.

It's about stability and what the phone requires of it's resources. Lol. Not OCD perfection.
Can you change the IO scheduler on set CPU? I know you can on voltage control.

^^this but I add the 1400 step at -25 as well... my phone doesn't like being undervolted past -25 on any step above 1000
I have at max: 1200 MHz ,at min 83 and in typeerformance, are these values corecct or wrong for a custom rom?
-Greeting-
PD:Andro's Rom (3 days for release)
Yes, or no, because you need a screen off profile or your battery life will be damn short.
I think this should be in the general section and i recommend using the conservative governor over the performance since conservative goes to the minimum frequency when phone is not being used i.e. when screen is off. This is best for performance since it automatically goes to the maximum frequency when screen is on and when screen is off it goes to the minimum which is good for battery.
1200 is too high....
It will damage your battery....
I use 100 MHz to 800 MHz....
Its average and most of the users use the same....

That frecuency will eat your battery.
I use my SetCPU at frecuencies 400-800Mhz, and use profiles for screen off (83-400Mhz), battery <20% (200-600Mhz), time (2am-6am) (83-83Mhz powersave)
always on demand (except time profile)
Greetings
My config is
Main 400-800 Mhz Ondemand Set on boot
Profiles
Temp >45°C 200-500 Mhz priority 100 Ondemand
time 2am-6am 83-83 Mhz priority 95 powesave
screen off 83-500 Mhz priority 90 Ondemand
Battery <20% 200-600 Mhz priority 80 Ondemand
I have g3mod 2.0 OC kernel
Greetings
I just use basic settings, no profiles or anything. Look in my signature.
I may add a few profiles after my lil bro is finished playing games on my phone.
My battery temp is 39 degrees Celsius is it that a good tempeture?
anything between 83 and 800 would work like charm and enough for day to day tasks..use conservative governor..set profile for screen off and on call..

What do you mean? You want to over- or underclock or stay at one frequency?

they all do. it only will go to max frequency when it needs to, otherwise it stays below. you can always set max frequency as max and as min, then itll stay only at max cpu speed.
For example, when the Antutu cpu decreases the frequency of max. less.

right. thats thermal throttle kicking in. if you have root, you can disable throttling, or you can always cool down your phone in a freezer before running antutu.
I'm pretty new to Android. I got my N5 2 months ago and rooted it as soon as I took it out of the box to get rid of the navigation bar. Didnt install any ROM or kernal.
What I did today was try to overclock it. I wanted to test the performance upgrade with Geekbench 3.
I got 2500. Tried to overclock with this app called: No-frills CPU control. And suddenly I get no higher than 2000...... Tried everything. I'm stuck at a multi core score of 2000 in geekbench while it should be 2500>.
WTF DO I DO? My device is noticeably slower, it's like a GS4 D: I'd rather not install any kernals/Roms
I set the minimum CPU frequency to 300Mhz and max to 2.266Ghz
Hi,
Thermal throttling..., overclocking produces more heat than the stock CPU freq so more thermal throttling. To prevent any damage, the CPU freq decreases according to the CPU temperature...
Let cool down your phone.

Sure, I'll turn it off for a while.
Just to make sure: the standard CPU frequencies are 300Mhz MIN and 2.266Ghz MAX, right?

Yes, that's right 300 Mhz-2,26 Ghz.
Not necessary to turn your phone OFF , when it boots it's a process that causes "heat" at the beginning then you will need to let it cool down again. EDIT: oups, you mean the thermal throttling OFF maybe?
Don't touch it for a while, airplane mode can help. If you are in a "hot" country/weather, air cooling, fridge...

Hi I was just wondering should I be worried, I was messing around with my phone tweaking it and installing a few mods and my CPU temperature went all the way up to 38 degrees Celsius, I'm not sure if this is normal or not? Please respond

if you install mod to boost performance or overclock cpu you should expect higher temperature.
however 38 c is not too high. have you tested temperature before those modifications?
specify mods you install to get better help :good:

How did you read-out the CPU temperatures?
Becaus 38c CPU is really low if you do heavy use your phone.
the temperature could possibly be the battery...
use this App to check the real temperatures... and don´t be afraid.. CPU rises upt to about 75C
