overclocking dhd

I have recently rooted my dhd and currently running CM7. Using the cpu setting within the performance menu I am wondering what peoples thoughts are on a noticeable but safe increase of cpu speed. its set as 1017MHz which i believe is default. I am told I can run anything up to 1500 safely. can anyone confirm this and also tell me what kind of result (performance and battery life) i should expect.
thanks

Well, I use Android Revolution HD (a sense rom, meaning heavy UI!) and i overclock to about 1.3GHz. In terms of battery life when it's awake, it seems a drain a teeny bit more readily, but I've never had a freeze on sense (quite rare)
On stock it underclocks to let the processor max at around 400MHz when the screens off, so that helps to really save a lot of battery on standby. On CM, I'd expect it'd feel more or less the same in terms of performance after you hit 1.2/1.3GHz

thanks for the reply mate. going to try out revolution HD soon i think. have you overclocked using a third party app or is there one built into that rom?
also im a little confused by the governors. 'on demand' is the default governor. Does that mean it will only use the max selected cpu speed when necessary? would you recommend using a difference setting?
cheers

The CPU is managed by the ROM itself. You can tweak it yourself by using setCPU (or similar), but I can advise you not to. Can't help you with the governors buddy, since I dunno what it is

nice one dude

I'm running cm7 and I'm overclocked to 1.5 ghz. It's been totally fine for months.

Lucky you picked a linuxhead!
The system itself has a daemon (background process built into the system) that handles overclocking. It's all explained on the page and also on this thread:
http://forum.xda-developers.com/showpost.php?p=14638641&postcount=34279
You can use another app (like SetCPU) but the daemon usually handles screen off's quicker. The governors basically determine how the processor frequency is changed. I'll explain the common ones:
Performance - Runs at highest speed, so if you have a range of 200 to 1.3G, it'll stay at 1.3G all the time, not usually the best
Ondemand - The universal default for phone overclocking, it only changes the speed up after a certain percentage of the CPU is used, and it switches on the fly, so if the CPU is used too much at 400MHz, it'll ramp it up to maybe 600 or 800, and if it's still overused, it'll put it up to maybe 1 or 1.2G
Conservative - This is like ondemand, except it makes the changes more gradual. It can give noticable lags in the foreground at times, so this is mainly used when the phone is asleep (screen off)
Smartass - This governor is like ondemand, except it'll less readily switch frequencies to higher values when it detects the screen off. This isn't really used because the overclocking daemons take into account the phone being awake or not
Basically, there isn't really a need to change governors, only really frequencies if anything. The thread, however, does tell you how to change governors.

Im using latest LeeDroid GB 3.2.1 and to be honest with the work he's done with the Kernal (3.1.8BFS) I have found that the ROM is a lot MORE responsive without me overclocking the CPU.
Im not really sure how it all works, but I guess doing this on different ROMS has its own different out comes.

overclocking has me confused too, is there really that much of a benefit in it? how much will i gain from it?

There is a benefit when you use certain apps, or even sense itself. For example, I've never had sense ui freeze, or go slow. The under clocking helps to improve the rubbish battery life when your phone is asleep.
In terms of measuring the gain, I have no idea. Really, I'd think you could use a process heavy app, or benchmarking app and see.
There's also loads of guides on overclocking to help out! (that's how I got the hang of it! )

For the need on OC, it depends on the kind of apps u're using. If u're happy w a non OC DHD, its totally up to u.
But for the UC, it works as a terrific battery saver, mich better/effective than other battery saver soln on market

The safe range depends on the DHD as the manufacturing changed even though same part, i'm OC 1.5GHz "On Demand" profile and under clock 245MHz on screen off "Power Save" profile.
Getting approx a day usage on Lee 2.1.

On and off system lag. Is it related the amount of apps installed?

I am currently running mikG 2.45 more freedom. Titanium backup loaded 335 Apps, which include system apps. I am thinking the maybe 200+ apps I have installed are the reason for the on and off lag.

Apps maybe be paying apart in it but you say your running "more freedom" try running the stock freedom not the more or less or extreme or whatever he calls them. The undervolting may be limiting your processor. Also use set CPU and try to overclock a little. Im running synergy rls1 with stock freedom overclocked up to 1152 smooth as a whistle and battery is through the roof. try stock freedom and if that dont work pm me and ill help u out more if needed

I was going to try aggressive freedom on the old one and 8.5. Wow overclocking to 1152 I thought that would drill my battery into the ground.

Overclocking doesn't really show a noticeable impact in my experience. Only if you are playing a CPU intensive game that pins your CPU at 100% then it drains slightly faster not to bad tho. Also if you use the "interactive x" governor it manages the cpu's frequencys to try to keep them as low as possible so you only using enough to do a task instead of going 100% for something that doesn't need that much power. It also keep the CPU at the lowest frequency you allow it to be when you shut off the screen. So if you set your Max to 1152 and min to 245 for example. When you shut off the screen it will stay at 245 and not jump around. That tremendously helps battery. It about 8p.m. here and i have had ghis on since 7 a.m. and I'm at about 30% and that's with quite a few text, 2 - 5minute calls, about 20 minutes of games, and an hour of music. The only bad thing about overclocking is that if you go overclock to far for to long you can fry your phone. But ive been running 1152 for about 6 months and perfectly fine so i figure that's pretty good. If u have more questions or need help pm me
Edit: i forgot i also had about 20 min of internet/xda browsing on wifi and the past 45min on 3g doing the same thing haha

[Q] SetCPU - Extra Info?

Hi there, thinking about getting SetCPU - I have some questions before I do because I hear it can be dangerous?
- I've heard it can brick your phone?
- What if you set it too high?
- Do you personally have to monitor it?
- What are the benefits?
- Use alot of battery?
- Is it really worth using?
- Is it optimized for different phones - example the One X?
Thanks guys!

Hi, i have read that SetCPU cannot view all the cores i have read alot saying that System Tuner works fine you might want to try that.
I used to use SetCPU on my sensation and never hand any issues with it i did not monitor the app at all
Benefits allows overclocking if available in kernel
it can be overclocked and cause some issues such as overheating but if set correctly will be fine doesnt use much battery if any
and no i dont think you can brick your phone
if you set it too high i believe i had to reflash rom nothing major
BTW this is based on my own knowledge and usage
Hope this helps

Thanks man

How much battery life can you save using setCPU?

None in theory, if the CPU is slower it takes longer to go from
idle - process - idle
Faster speeds allow it to get it over and done with faster and get back to idle.
Of course it will at times stop the CPU going higher than it needs too which could save battery.
Under volting will save more batter then underclocking ever will.

Thanks. I have system tuner, but what do I need to do in order to improve battery life?
I have set the governor to powersave. Is there anything else? How would I undervolt using this app?

undervolting requires your phones kernel to support it, currently on these forums there is only one that does but i haven't tested it, sticking firm to the "stock kernel is best" and will do untill the kernels have more time to mature.
you could limit your max speed to 1 GHz, if you are rooted you can use Core control to turn off cores and run your phone as a dual core.

Not to be lazy, but would running the phone as dual core and limiting it to 1 ghz result in a perceptible battery savings? I'm trying to get a feel for how much I should expect custom ROMs to make my One X perform up to par. Thus far, I've installed two custom ROMs and felt like the improvements were all safely in the minor category.
I did install cyanogenmod 7 on a phone last year wow, that resulted in major benefits.

Running on 2 cores stops the phone from using and 2 cores uses less power then 4, playing games and using all cores is over kill 2 cores will run the game without lag use less power and make less heat.
You'll maybe get 10% from doing that but I haven't tested.
Really the only time any of this saves battery is during demanding programs, tegrea has a super low power companion core, for all your power saving needs.

I tried conservative governor while downloading sd files for Nova3 gave execllent results
I strongly advice not to undervolt tegra3
t3 is not like any other chip and UV or OC should not be attempted
OC because the chip is already at the max of its thermals
UV for the same reason n might end up with problems like flicker
changing governors and UC should be enough

[Q] CPU Temperature exceeding 80°C! How dangerous?

Hi guys,
I understand that some heat when running resource intensive applications and games is to be expected but I believe I've passed into the danger zone, so to speak. When playing XCOM my CPU temperature quickly exceeds 80°C. From my googling on the matter I have come to assume that a temperature as high as 80°C is dangerous for the hardware of the device, but I have had trouble finding upper threshold limits for the model itself.
I guess my questions are as follows:
1) How damaging would running the CPU at 80°C for an extended duration (1hr +) be?
2) What would you consider the max acceptable CPU temperature to be?
3) Assuming it is as bad as thought, what are my options to reduce the CPU temperature, short of avoiding the problem applications? Underclocking seems to be a common suggestion, but I get the feeling that XCOM, or similarly taxing applications, may just fail to run or become incredible sluggish under such constraints.
My device is rooted and running Lean Kernel v2.4 along with the w03Slim ROM. Found here: http://forum.xda-developers.com/showthread.php?t=2638116
I've done similar test runs in the Temasek kernel with the recommended configurations through Trickster Mod and there is no difference, the CPU still exceeds 80°C when playing XCOM. After a week or so of googling, searching the forums, and digging through device manuals I feel like I'm spinning my wheels.
Any insight or advice you all might have is greatly appreciated.

Solved!

Does not exceeds to 80c now?

You can try a custom kernel, i would recommend you BioShock kernel, with conservativex, max freq 2.2 ghz and undervolt 25 mV... No more over warming for me, great performance and battery life

Agree with this post, conservativex is a great governor to keep your cpu in check and not over throttle itself, also check out my thread I made here awhile back and apply the 8th post down. It really helped keep the temp down on my phone when playing graphically intensive games like dead trigger 2,riptide gp2 etc. Also if you have trickster mod or faux clock(really recommended) you can scale down your max frequency, that should really help keep it cooler and you won't see much of a performance drop (if any) while gaming or heavily using your phone.

cup throttling for battery life?

Hi everyone, I'm New to rooting. I've already used towel root, Greenify and my standby is amazing. So far, my on screen time is hitting 3 to 4 hours. Can anyone help me with what software to download, and what settings to safely use to ccontrol the cpu to help battery life? Thanks

Cpu tweaking won't be a thing till customs Kernels, we don't have undervolt or good governors
We should be able to underclock but I don't like that idea much on anything
The Cpu governor right now is set to interactive on all cores by default
And row as io sched by default

CPU throttling isn't going to be a huge help anyway. That's a pretty minor effect in battery usage.
