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

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.

(Q)I have a og evo and cant overclock it 1.2ghz.

I have a og evo I want to know why when I overclock to 1.2ghz it freezes my phone why does it do that ?
Sent from my Nocturnal 4G using xda premium

Each Evo is different. Some of them can't handle that high overclock, or can't be undervolted very low. Each one is different, each has its limits.
I don't understand the big deal with overclocking. It burns your battery faster. I personally underclock, with little to no lag and is good enough for my casual gaming needs

Mine doesn't like a clock much at all. I can get about 1.1 before it starts locking up but even then it hangs a lot. I honestly don't see a difference from 1.0 to 1.2. Get a decent rom, good kernel and try out the v6 script an I almost guarantee you will like that better.

Well for us to be able to help you, you would need to provide us with more details on how you are trying to accomplish this.

I use no frils cpu but have also tried setcpu and viperMOD I know that's the best way to overclock but is very confusing. Have any step by step instructions to of to 1.2 I know having higher voltages helps as well.

Overclocking is overrated. If you need to overclock for every day usage, then something is wrong - at least in my opinion. Resource intensive gaming is different, but you shouldn't need to overclock for browsing, texting, casual games, etc.
Try out the V6 Supercharger script. I'm not currently using it, but have in the past and it seemed to make my phone more snappy. A lot of people swear by it and it's a great script, definitely worth a shot. There are other things you can do to speed up your phone without overclocking. I'd try other options first since overclocking will chew through your battery. Increase the dalvik vm heap size, there are plenty of free apps on the market to help with this task. Uninstall apps you don't use, I'll bet that you never use some of the apps on your phone. Back them up with Titanium Backup and you can restore them if you ever need them again.
In case you didn't already know, the Evo can't overclock past 1.2, I'm not 100% sure why - it has something to do with the processor.

I never oc over 1075 and only when plugged in if i play a game I need to oc.for I just activate my charging profile and plug up and play 1.2 ghz is a good chance of doing serious.damage as these older scorpion processors get very very hot at that clock speed so they lock up to try and protect themselves from heat damage or they shut down the phone 1075 is as high as you should need to go for any games the evo can handle on the subpar gpu

I'm pretty sure viperMOD is more for undervolting than overclocking, which are not suppose to be combined together. I am running vipermod with max voltages - 50. Other nite was playing snes9x and was getting some lag with a game so I bumped max CPU up to 1.2. Phone went into a bootloop and had to superwipe and reflash everything. Don't know if its b/c vipermod + 1.2 CPU or just bumping up CPU. Didn't try it again.

You can overclock and undervolt together just fine. You just need to ensure that every frequency has a high enough voltage to run the processor at that step. My Evo is overclocked and undervolted just fine, although IIRC I can only push it up to 1.1 GHz . My tablet is 1ghz to 1.6ghz and is undervolted as well, though.

merge rls 2.0, iron monkey, Droid overclock because of the profiles options. I set up four profiles including one for temp. sometimes i'm underclocking and sometimes overclocking but only up to 1.19 to prevent freeze and boot loops. Only downside is right at open Droid overclock needs su permission but that is my choice since profile changes at open.
Very snappy afterwards.

When I had the 4G, I was never able to go above 1118, or somewhere around that. It would have freezing issues.
On my evo shift, I was able to do 1.7 gHz (compared to stock 800 mhz) ok. 1.6 pretty reliabily, and I could run 1.5 all day long. Some guys could do 1.9. It just depends on the phone.

Actually overclocking and undervolting is counter-productive. What you should do, is read carhaulers and ropodopes guide over at vaelepak. Its give some good useful info about how to set up a good aosp rom. I'm underclocked, undervolted, and still getting 1400+ benchmarks. Check it out bro. You'll love the results.

What? Overclocking and undervolting are two completely different things, and they aren't mutually exclusive. Unless you can provide a good reason as to why it's counter productive to do both, I don't buy that at all. Just checked my phone, my overclock requires an extra 25 mV for all three steps I've overclocked. 25mV isnt much, and it certainly isn't going to kill my battery that much faster.
Besides, the only time the CPU is going to be entering these high power modes is when it needs to do work, and it's better to do work as fast as possible to go back to sleep. Would you rather wake up, do a mundane task for 5 minutes, then go back to sleep or wake up, do a task at 2x the speed while only consuming 30-50% more energy, then going back to sleep after only 2.5 minutes?

First let me say I don't use viper mod or any voltage controlling mod.
On sense 3.0 roms such as mikg I over clock to 1152 and set the minimum to 384 and its smooth as butter. No problem and battery lasts all day.
On aosp however such as decks (I'm on it now) I underclock to 499 and leave the min at 254. Smooth as always and battery lasts forever.
Anything past 1152 is going to cause problems (at least in my experience) also the rom/kernel can effect how much you can overclock.

Its counter productive because it is giving less to something that needs more. (Don't take this post as me trying to be a ****. Just voicing how someone explained it to me a while ago)
Think of this as cars.
Lets say you have a nice fancy v8 mustang. Stock, everything is well, balanced.
If you start adding parts and get it pushing out 1000 horsepower (overclock) your most likely gonna need more feul (voltage) or at least stock amount flowing into the engine just to keep it running.
Now lets say you got that same 1000 horsepower gas destroying mustang and you start to lower the amount of gas flowing into the engine (undervolt (done in vipermod)) cylinders (CPU) wont get enough gas, it wont work, and your stuck going no where.
So if that made sense (did to me) then you can see why they are counter productive. Unless your using vipermod to overvolt (which idk if you can since I don't use it) then you can disregard this whole post

Your car analogy is completely irrelevant. You can look up the exact voltages that the CPU runs on at every frequency, *even when overclocking*. Overclocking an Evo 1ghz to 1.2ghz takes maybe a 5% bump in voltage, and that 5% extra power is only going to be used *when the CPU is running at max speed* (which is only when there is a lot of work to do), and even then, it's *still better to let the CPU run at max speed with a tiny bit more power consumption than to cap the CPU at a slower speed and make it work for even longer*. Intel calls it HUGI, Hurry Up and Get Idle.
I know what I'm talking about, and I wish people would stop trying to argue with me based off of second hand speculation. I do this for a living, after all. There is absolutely nothing wrong with overclocking and undervolting, and it's the best way to get the most battery life *and* performance out of your phone, period.

Hmm, *interesting*. I believe the best answer to the OP was covered rather well earlier. It's all about your rom/kernel/hardware combination. With all the variables to consider as relevant, your best bet is to experiment and find what works for your device. Don't check set on boot untill you are confident the set-up is stable. Higher is not always better with overclocking. My device runs blazingly well underclocked @768max. Gets insanely great battery @499max. However my quadrants are better @ 1036 than at 1190.
Great thing about android is you can experiment and learn through trial and error.

Way more simpler actually.An app shows you your available frequencies choose the one you want and done.Oh and its live OC to.

Overclocking a phone is not easier than overclocking a PC.
Phones have many CPU steps so you have to find the right voltage for each step.
Also you can only change CPU voltage and frequency. (Some kernels allow you to change bus speed which is nice but alot don't support this.)
The only sensor you have is battery temp.
Furthermore, when overclocking a pc, you can just run prime95 for 10 hours and you know your stable. With the phone there is no difinitive stability test so sometimes something might trigger an instability afte you have been "stable" for a while.
Also no third party cooling. (As far as I know)
Im not saying it's really hard, but honestly when you come from PC overclocking you will probobly get frustrated about some things.
All that being said, overclocking a phone is super fun and I hope I didn't scare you away from it in any way.

Am I the only one who isnt interested in overclocking in the least bit? I mean, the damn thing is fast enough already. I can understand overclocking something old like a nexus one, but wow. What do you guys get out of OC? What do you use OC for that requires the higher speeds?

I custom built my computer, im sure i can overclock it to who knows what but it being so new i don't even think about it. Maybe in 2 years when it starts showing age.

Most people that overclock their PC will get a new one before they really need the speed anyway. It's just because its is fun. And plus if you know how to overclock, there is really no reason not to. It's not like it's a trade off, its just free performance.

gotcha, i wasnt meaning to be disrespectful, i just never understood it unless needed.

You should try overclocking your PC. You might find that it is very fun.

Undervolting CPU - More battery...

Is it worth it?
How do I go about testing the stability of the phone ( I don't want to reduce clock speed )

If you want your phone to work perfectly without loosing speed it's not worth it ( change wouldn't be noticeable )

If you're not sure about what you are doing it won't lower performance it will probably result in a lot of crashing and error messages, I personally think it's not worth it for the amount of battery you could gain ( few minutes )

Well, I have had it undervolted with -150mv in a week or something and I haven't experienced any errors and crashes. I don't have it for the battery, but for the temps.

I've been under voting my s3 747m for over two weeks now, between 75 to 300mv lower, at 1.89 I'm running at 1200mv, although I'm only running it at 1.5.
To test it I use Stability Test app, on scaling for 3 hour runs, it will stress all frequencies.
If you find a crash you increase the voltage at that frequency, BUT, the best way to test it, instead of using scaling test, use the burn in one, but manually set your speed and let it stress test XX frequency for a long period, this Is where I found the most of my crashes.
This isn't an easy or a quick job, it'll require a good weekend of mucking around. I have all my speeds down to 5mv increments instead of the stock 25 the apps give you.
But so far, I don't get voltage related crashes, only the random KP caused by cm10 bugs.
If people are interested in the voltages for this phone I could post them

I want to know if we can overclock our Snapdragon 808 to 2GHz (ARM A72 cores) with a modified kernel.
Also, If somebody is going to work on this challenge.

A57 cluster, probably yes. I'm also working on a kernel, but I intensely dislike Overclocking because it isn't all that useful. The key to performance is with optimisation, not with raw power. So I'm most likely not going to include it, sorry.

What about underclocking and/or undervolting?
I think performance is good enough as it is, but would like to get better battery life.

I would like to be able to undervolt in order to relieve the bugging high temp warning. This phone rarely uses max performance. So, overclocking is not really a priority. Maybe a custom hotplug.

Crappy cpu. No point messing with it.

Hotplugging has been dropped not long ago. You'd basically need to reinvent it. Plus it costs more power than it would save

And what about undervolting to prevent excessive heat, @mythos234?

yea i guess undervolting is the only benefit here coz 2 ghz wont be hard to achieve but getting that overheating msg sooner aint worth it...
next thing u know is accessory back plates with mini fans to keep the phone cool...
seriously tho what good is the extra power for ? the phone is already fast with the correct setup (not that i saw any lag when it was stock)

anyone knows how to see the cpu binning in this phone?

A number of people have gotten over-temperature messages, sometimes with the phones even shutting down.
This has been reported with using navigation, I believe, and I know people have reported it when shooting video. High screen brightness is likely a contributor. But there are examples of the phones running too warm.
Personally, I'd be more interested in cooler running, and longer battery life, rather than increased peak performance. So underclocking, if anything.

Well, the overclocking is not necessary, but is an opportunity to know the limits of the chipset. Moreover, with it we could know if we can make undervolting to our phones and make it more battery efficient with an underclocking kernel, when we need it.

Happens to me too when gaming. The problem I observe is that Indeed, it is not excessive heat. But LG thinks otherwise.
You can actually underclock using Kernel Auditor and disable cores. Unless you meant Undervolting.

Wanna check out periscope and comment back ? Atleast I know that app will push the phone to its limits.

Currently using Kernel Adiutor to disable both A57 cores and the phone screen does not heat up like before... Battery life has improved from what i saw yersterday. Continuing testing today. Only problem i have is the damn phone will enable one of the A57 cores after a while which i dont like. I need my settings to stick.
Any Kernel Dev know which files are causing this? Tab 3 had something like this but a couple of files changed solved the non sticking settings on cpu.
Overclocking/underclocking sure but just disabling cores would work for most.

I haven't had any popups or heat related reboots, so I was wondering what the matter is here.
On every phone I see complaints over heat so I wondered if something is to it here or if it's the usual. And if there are overheating warnings and shutdowns, then there might be indeed something in the bush.

Try charging your phone in the car whilst using google maps to get to an important meeting, and then take a call just for good measure............and boom, there you have your own little meltdown.

That happens on every phone I ever had though. It's advised to not use a device while charging at all, so if you stress it to 120% while charging, of course it heats up..

@mythos234 is a pleasure to have you here (speaking as xiaomi mi2s owner too xD)
What Temps do you reach using cpu intensive apps?
