I'm having an issue with my phone not being responsive if I set the CPU to 400Mhz. I first found this problem using Juice Defender then I uninstalled that and did it under SetCPU and it still did the same thing. The phone pretty much doesn't wake up after a while. I have to do a reboot in order for it to work again.
Don't get mad at me but IMHO overclocking and messing with a phones core features (what makes it run, processor, ram, etc.) is unsafe and can cause instability. And no I have no scientific research to back this up but it's just my two cents.

Lol I'm not mad. I don't really like to over clock. I just figured under clocking would work better. But nooooo lol

It does that under 800 mhz I forget why but I've read that in a couple places

underclocking that much is using less than 1/3rd of your true processor power.
your processor simply is not able to draw enough power to perform its background tasks - even when the phone is idle - when you underclock to such an extreme extent. therefore, it freezes trying to complete these processes.
if you're going to underclock, i'd say that 800 MHz is the lowest you can go if you are expecting your phone to do everything it is supposed to do. although it isn't going to save you THAT much battery life anyway, so you might as well just run it at the stock setting of 1200 MHz.

I understand LOL. And he's right underclocking honestly doesn't
Save much battery.

There's a known issue with setting CPU profiles to less than 800 MHz. A fix exists but some kernels don't have it.
Many of our Gingerbread kernels fix it, Infusion-GB is one of the few that hasn't pulled in the fix yet. (Although version 1.1 may have pulled it in, haven't checked github lately.)
None of the Froyo kernels have an explicit fix, but I'm not sure if the flaw even applies to our Froyo kernels as the clocking architecture is VERY different.
Hi, Rogers stock 2.3.3
It's using up 60% battery over night. Most likely I should turn off Wi-Fi.
I have underclocked to 100, 200, and 400 and it's stable --- minus the delay/lag at 100 and 200 . Sorry to seem like a troll.
I find that by default this phone either runs at 100mhz or 1200 on average, and 200 400 800 under 10%

Bumping from 100 to 1200 is classic ondemand governor behavior.
Also, some people never had problems even without netarchy's sleep patch running the CPU capped to 400 - but others have. I don't think anyone has had a problem with a patched kernel.
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?

Our phone support overclocking to 729 max and min 320 if you underclock it your phone will be laggy and not responding . Those frequencies are the best for it and will not harm your phone.

ya i know underclocking will definitely reduce performance. What if I keep the Max freq as 600MHz and reduce the Min freq to 245MHz. I just want to know whether it will harm my phone or not.

I'm using oc since the first week I owned my phone and it's running fine.So, min freq:480(it use the same freq as lower clocks and reduces wakelocks) and max:600 or more

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.

Are you sure...?Take a look on what fserve posted in his kernel thread:" NOT underclock below 480MHz. At lower speeds, wakeups-from-idle per second are bigger than 480MHz and they share the same voltage, so thats leads to more battery drain. It's recomended to use: MIN 480 / MAX YOUR CHOICE more about it: http://forum.xda-developers.com/showthread.php?t=999064 and here: http://forum.xda-developers.com/show...2&postcount=22"

Sent from my LG-P500 using xda premium
I use setcpu to set the clock to 122 - 320 while the screen is off and the phone sleeps very well but sometimes it freezes when I wake it up so I had to change it to 245 - 320 and evertyhing is fine now.
Hi yes im new but not quite a noob :cyclops:
There with that out of the way my overclock settings are 1200mhz min 1600mhz max
so far running great with the HellyBean rom
But how would this effect my phone long term if any and I would like to be able to moniter my cpu temp like I do on my pc
but the thread http://forum.xda-developers.com/showthread.php?t=1140371&highlight=cpu+temp
has some good apps but they don't say cpu temp just the battery temp unless there interlinked some how
Thanks for looking
No temp sensor on the infuse except for battery.
1200 is really high for a minimum... This should be 100. For performance set governor to ondemand.. This will Max the cpufreq on any load. When idle, freq will drop and save battery and cool phone.
Running for extended periods at 1600 your phone will get very warm to the touch.. Combo of cpu and screen... If plugged into charger that will add more heat.
Battery Monitor Widget is a good app for tracking battery temp and related stats over time.

Thanks ya I figured it was a bit high
Do 100 min and 1400 max
And governor to on demand
Also i set up profiles with set cpu so when screen is off the maximum goes down to 400mhz.then screen on profile the max is 1400.it saves battery

How do you set up profiles?
Sent from my SGH-I997 using xda app-developers app
Use a CPU manager like SetCPU ($). Voltage Control or Antutu CPU Mgr may also have profiles.. Not sure -it's been a while since I used either.
Sent from my SAMSUNG-SGH-I997 using xda premium
The only ones I found so far that have profiles are pay for but once I get one I think its going to be either ROM manager or antutu

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

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.
