OK, first of all I'd like to apologise for all the questions I keep posting. Im quite a noob with android, and coming from an iPhone, it's been a big leap. I'm just overwhelmed by the android system and how open it is! But I do all this cool stuff to my android like everyone else, although I don't wanna ruin a £350 phone by doing something stupid without guidance! (I'm just a big kid really! ) Which is why I keep posting questions, because it's hard to Google/Search XDA for this stuff...
Whenever I search XDA for 'Nexus 5 Overclocking' all I get is ROM threads, so this will be a thread for everything [under][over]clocking! Share your most effective results, and ask the pros questions!
I'll start it off...
I've Underclocked before, but now I wanna Terry out some heavy emulators (dolphin emulator, Nintendo 64 emulator ect.) But I don't think my phone is powerful enough to run these games full speed underclocked... I want to OVERclock it now, so which apps do I need to achieve this, how do I do it, and what are the most effective values for it?
Thanks,
Pro_Vickers.

The kernel defines whether or not you can overclock.
There is no real need to in the nexus 5 though.
If it is choppy at 2.3ghz then there is something wrong with the emulator.
In context I play final fantasy 9 on the psx emulator fpse using opengl graphics (which is limited to single core) and still get a constant 60fps

Hi,
First you need a kernel with overclock (Franciscofranco, Trinity, ElementalX, etc...).
For the apps Franciscofranco have its own app (Francsico Kernel Updater-> FKU) and Trinity kernel also (Trinity Kernel Toolbox-> TKT), all available on the Play Store.
You can use a "generic" app like Trickster Mod, Play store too.
With the apps you choose your max CPU freq and it's done...
For overclocking there is no "most effective value" it depends of the voltage and what your CPU can handle. 2,4/2,5 Ghz seems reasonable (with some kernels you can go above like 2,8 Ghz).
Try a "safe" overclock first like 2,4/2,5 Ghz, and don't set the CPU freq "at boot" to avoid any problem like bootloop in case your CPU can't handle these freqs.
Maybe you'll need to raise a bit the voltage for these CP freqs, it depends of your CPU binning.
You can apply your settings at boot via the app when you are sure that all is stable (so after a few days of test with your use).
In any case you'll need to test in different situations to see if all is fine (hard and normal use)...

I've Underclocked and it's choppy, but I know it's not the emulators fault because of the reviews, and I've played with it before I Underclocked... The problem is, I forgot how I Underclocked, so can you tell me how I clock it back to stock GHz?

I have Franco kernel so clocking shouldn't be a problem should it? Also can I use trickster mod for it? Thanks

But in first I would try with the original voltage, not necessary overvolting...

Ok...
Hum... you choose the one you want, you want to overclock so overclock. The stock CPU freq is 2,26 Ghz so if you go above this freq you overclock...
Maybe it's why "But I don't think my phone is powerful enough to run these games", like you said, if your max CPU freq was at 960 Mhz...?
Default the stock max freq will be 2260 MHz or 2.26ghz depending on how it's displayed.
I'd leave your undervolt as it is for now and just increase the max frequency and see if it becomes smooth for what you need

I know that my phone is fast enough (obviously, it's a nexus 5 beast!), and I know that I lowered my CPU frequencies, but it's just that I forgot what the defaults were, and how to change it. I know now, thanks you guys! P.S should I change my min frequency or is that fine?

Ah ok, you should have explained it at the beginning... , you're welcome
Stock min CPU freq is 300 Mhz..., not sure you'll see any gain to set it to 422 Mhz...
Set it again at 300 Mhz and see...
In any case if sometimes you have a doubt about some stock settings, disable the set on boot option and reboot, all the stocks settings will go back. Or in FKU, App settings then clear data for FKU.

I'm sorry for the noob question but I really don't understand voltage terms and what's it for and how it work I was wandering if anyone could explain it to me?
In the past I would use set CPU and create a few profiles and would be done with it but I been reading on the forums about setting voltages higher and lower for better performance.
Currently i'm on eagles blood 2.3.5 ROM, trinity t15 (fun) kernel.
Any help would be much appreciated.

It's to save power and get better battery life. You lower the amount of power the chip gets at various clockspeeds until it starts not working correctly, then back up to a voltage at which the chip is stable at that clockspeed. Some chips can handle lower voltages than others while still working correctly.
Overclocking = get better performance
Undervolting = get better battery life
Both can lead to phone instability if you set the values to extremes.
Thank you for the info

It all depends on the kernel your using and if it supports UV, it should say if it does in the name of the kernel tho(just look for uv ) Setcpu 2.2.4 will allow you to change voltages only if your kernel/rom support it.
you can safely undervolt -50 -75 at most all the way up to 1.0ghz-1.1ghz i wouldn't undervolt past that.

So what your saying is I can use setcpu to change the voltage?I just recently changed kernels I saw that option available but I didn't understand how to use it.under voltages it shows all the GHz underneath it it shows 0.From here what do I do?, do I go too each GHz profile and -50 from all of it?

Like many parts of the world, here in Australia it can get very hot. I would like to have my Galaxy Note automatically slow down when its too hot. I'm thinking this might mean a CPU governor that checks temp as well as CPU load.
If something like this already exists then does someone know where I can find it?
Otherwise I wonder if its not too hard to modify an existing governor to include temperature based throttling.
Currently I use CPU Master Pro to enable an overheat profile when it hits 49°c but you can get days here where the air is that hot! It needs to keep slowing down if it keeps heating up more. Even CPU Master Pro can't do that.

Use setcpu profile.
Make a profile in setcpu, set the rule to if over 40 degrees limited cpu from 200 mhz to 1000 mhz. Its very easy

Hey guys will overclocking drain the battery quicker even with stock voltages?
Sent from my Nexus S using XDA Premium App
Different voltages are specified as stock for different frequencies. As the frequency changes, the voltage does too. Running 1200mhz with the stock 1000mhz voltage will probably cause instability and crashing.

And if increase voltage, the power consumption should also increase.
i haven't played with voltages yet but in my experience the benefits of overclocking are minimal anyway, and they make nexus reboot often and other bad things :/
With the right settings you can get a fully stable and functional overclock, but it is on a per-phone basis due to varying quality of the same CPU during manufacture.

Currently I'm using icup kernel speedy 5 clocked at 1.4 and its been extremely stable. So what your saying is that the voltages automatically increase when I select a higher frequency, because I did not change them manually.

Open NSTools and select Voltage tab. That's the list of "stock" voltages for each frequency.

A CPU governor such as on demand, lulzactive and lazy tells the CPU what clock to be at and automatically change. While reading, it will be at 100 or 200mhz, while playing a game it will be at the maximum clock you tell it to. Saves power this way.

yes, usually 1 GHz is enough , UV or OC also may reduce hardware's physical life
OK i have read up a little about live oc, but really i still dont understand it.
In NS tools there are 3 settings.... a % an "oc target low", "oc target high"
As i understand it the percentage is just how much each step of the cpu scaling gets bumped... so if your at 110% @ 1000mhz step it would actually be 1100mhz. And @ 110% the buss speed would be at 220mhz vs the stock 200. (is that correct)
But as far as the other two settings... oc target low, oc target high... what are those?
Really im just looking for a little more incite on how live oc works.
Thanks guys!
You can tell it to live oc within certain frequencies. So if you only want to to be on live oc from 200-800mhz, you can set it to do that

AHHH ok so the min and max are the range in which the live oc takes place. below and above those min and max values it goes back to normal?
how much rise voltages from 1300cpz/100liveoc to 1320cpu/110liveoc?
Bus OC don't work at all. I've tried 3d benchmarks with and without this and there are not difference

you must not be doing it right or applying works for me
EDIT: you do realize it will only over clock the freq of the low target and high target.
For example you run your benchmark and your cpu settings are going to be affected on the I/0 scheduler and cpu governor.
if i run Sio ~ On-Demand @ 100/1000 and my Live OC is 1200/1400 your not going to be using the OC settings because its only designed to, to OC the freq you chose it to.
So to make it work for benchmarking purposes i would run Sio ~ Performance @ 1400/1000 or even 1400/1400 so it would only use those OC'ed freqs. and have the Live OC either 1400/1000 say @ 105% or 1400/1400 @ 105% so it run Straight OC'ed freqs only.
Hi Guys,
I've been using custom kernel/ROM for sometimes now, and I hear a lot about overclocking.
And I know that overclocking is "not so good" for the phone. Was wondering whether the same applies for under-clocking also.
Oh, and 1 more question is about decreasing just the "Minimum CPU frequency" to something like 245MHz. Will that be bad for the phone?

Actually the point of underclocking is to use a different frequency, 245 will use a lower frequency than 480. Also, frequency has absolutely nothing to do with wakelocks, 122 will have the same number of wakelocks as 806. You should set the minimum to whatever works for you, some people like 245, some people like 320, some people like 480. Underclocking can't damage the phone, so use whatever works for you.
