CPU power

Hi there, the current CPU max for Desire HD on stock is 1GHz.
If we change to other custom ROMs and it allows us increase the normal 1GHz to say, 1.5GHz.. (overclocking?) will it damage our hardware?
Cause as far as I know the software should be supported with a powerful hardware as well.

Overclocking always has the possibility to damage the cpu. And as not all cpu's are the same, if you want to overclock, the best way is to start of slowly say 1.1ghz. And keep stepping it up slowly. If your device begins to get unstable, go back a step, and you will pretty much know the level of your cpu fyi ive had mine overclocked to 2ghz and it seemed to run fine, although i didnt keep it at that level for long. lol

I've been using minne over clocked at 1.5ghz since the day I bought it and I've not noticed anything as far as hardware failure. Being a computer technician I'm constantly trying to run what I have at the fastest rate without fail. I've not felt any overheating and per temps I've only seen about a 5-8°c increase over another user at work on the same ROM.

I have been running mine DHD at 1,2 for some time and ofc there is a chance that the CPU fries, because of the OC, but I don't think the chance is very big.
But please remember that the warranty of the phone dosn't cover overclocking

Hmm.. ok. Thanks for the advice.
I shall consider carefully before doing anything. Currently I am at only 1190MHz. Lol.
Anyway thanks again.

Well,I am running a really nice 1.8GHz,stable and fast as hell.Never noticed any overheating.
What most people should bear in mind is that the physical limits of our cpus aren't the ones that the manufacturers tell us they are with their spec sheets.Almost always,cpus are tested in higher clock speeds than what they are sold with,just to be stable and safe.
And one more thing.Correct me if I'm wrong,but doesn't the Flyer share the same cpu as the DHD?Cause it runs @1.5GHz stock.If they have the same cpu,guess what this means for us!

In setcpu,go to the info tab and do a stress test for some minutes.If it doesn't crash or anything you're good to go!

Thanks.
I did two ten-minute tests in SetCPU, the first 1,53Ghz and second 1.61Ghz, both without errors.
Anyone have any idea ?

Lol. Guess I will just try increasing the GHz slowly. Trying 1.3 now

I dived straight in, and set it to 1.5. No problems so far. Done a stress test successfully. But is there any need to increase the minimum level?

If you clocked your cpu too high, your complete phone will freeze. That means the only possibility to restart it is by pulling the battery.
If your browser closes suddenly without any notification, it's app related and not due to an overclocked cpu.

Well,to overclock you'll need a custom kernel,which means you'll have to be rooted and have at least clockworkmod recovery installed.ENG and Radio S-OFF are recommended.

ok I know, but I do not understand why when I enter the page, for example: speedtest, after a few seconds the phone is completely frozen (o / c) 1.22Ghz
I watch movies, play games, do tests, benchmark, etc. (o / c) 1.22 Ghz - 1.53Ghz. Everything is ok.
just a few seconds in the flash player and death:

Did someone try do downclock CPU to say 800MHz. Will it improve battery life?

Yes you can, you need to root, s-off and install a custom kernel first though.

Well,as AndroHero said,Flash is quite CPU intensive.However,your problem could be caused by the fact that your CPU isn't as "good" as others.By "not good" I don't mean that your CPU's quality is bad,it's just that it is unique like every CPU(nanometer scale devices like transistors are hard to be produced and be exactly the same one with another) and it might need you to up the voltages for higher frequencies.That by itself is no problem.
If the problem is indeed your CPU's limits,as it could be app related as Flussen said,and if you are running LeeDroid's rom or at least have his kernel installed,I could provide you with the OC script I am using myself.You see,I too am "suffering" from problems with the CPU not being able to handle too high overclocks,so I had to up voltages.Fortunately not much!

Well,in theory it should improve battery life.But calculating battery performance is a hard and tricky process.Just think about it this way;The CPU will run at lower voltages while at its reduced max frequency,thus needing a smaller electric current.However,it will need to run at the max speed for a larger amount of time.So,what you finally get is reduced drain,but for longer periods,meaning the gains in battery life could be minimum to non-existent.I for one am running 1.8GHz and battery life is just as good as @1GHz.

Do we need SetCPU apps when we have CM 7.0.3 Stable ?

I am a newbie on rooted phones. Just rooted the phone to CM7.0.3 Stable and found out that we have a setting to change the Govenors, currently set using SMARTASS with 245/729.
One question, is it nessesary to install apps such as Setcpu to overclock? or it is just adequet to use the setting in CM7 ? Will both conflict each other? Many thanks

Its useful I think, because you can setup CPU speeds for certain things, such as when your screen is off or when the battery drops below a certain threshold.

depends on you need dude. playing games/ watching videos/ hearing music/ simple phone usage/ battery conservation etc. stock one dont have profiles. but 3rd party like set cpu have it. so that it auto switches profiles according to ur present phone status.

SetCPU is much more useful than the cyanogenmod CPU functions, I did use the cyanogenmod one but I didn't see any changes

yes, the good things are the profiles! but I'm not sure if underclocking the processor really saves battery since i've heard that its just a saying/placebo

Yeah I think your right, strangely enough I think it's the same with overclocking, I put mine up to 700ish MHz and the battery still lasts just as long, I expected a reduction in battery life!

CPU frequency issue

Hi Guys! I'm on CM10 Nightly's kernel, and as you know it is set to max frequencies on all 4 cores, which causes crazy battery drain. I change CPU frequency manually but as soon as the phone gets rebooted it gets back to max. I tried to change performance settings and using some apps - didn't work. Any ideas how can I make CPU frequency stick to the one I pick? Maybe I should try another kernel?Thanx
Sent from my HTC One X using Tapatalk 2

I would recommend that you download SetCPU application from Play Store and play with it a little bit. But be careful, you could mess things using it.

I would start using a non nightly kernel. Nightly kernels could have bugs that could damage your device. My guess is that CPU frequency reset was put into the kernel for safety reasons.
Sent from my HTC One X using xda app-developers app

I am on nightly (seadersn edition) and checking apply settings on boot works fine with min and max frequencies. Also nobody has complained in the official cm10 thread. Try re flashing your kernel. And fastboot erase cache afterwards.

"No Frils" or "System tuner" apps will keep the frequencies for you

OP, I'm having the same problem as you - CM10, latest nightly. I'm really worried that it running at max CPU frequency will damage my phone. Have you managed to find a solution? I'm a complete noob at all this, and can't quite figure out how to install a new kernal. Thanks dude

Anyone else feels battery drains a lot faster on 4.1.2

Sent from my LG-F180K using xda app-developers app

nope, same with latest 4.0.4

Much better now that it's rooted and setCPU profiles are enabled once again F180L owner.

I actually see a really nice improvement in battery life over 4.0.4. My wakelocks are now 1/4 of what they were. My problem is CPU related - cant get up (to 1.5 ghz... Throttled down to 1.1 almost all the time)

Emm, why do you need 1.5ghz?

I am so confused by this question
Because, like many other people, I bought this phone in part for its processing power. I could have saved a lot of money by getting a slower but uncrippled phone (even stock gingerbread on my Galaxy S was 'good enough' for basic tasks). And yes, I have noticed lags since the speed has been mostly capped at 1.1ghz. I dont expect there to be full speed all the time, but I'd like it to be as snappy as possible when I am doing light activities with it, like web browsing. Why would anybody be content to have a 30% reduction in their phone's capabilities?
UPDATE: the lags I was experiencing seem to have been softare related. They appear to have disappeared after a clean install of JB and manual install of all apps from play store

Oh yeah. What is draining your battery? Is it a specific application or just the OS? If its the OS you can install Better Battery Stats and take a look at your kernel wakelock statistics.

Something wrong with your unit, cause mine one doesnt lag at all even on 700mhz with 2 cores disabled.
Also on 1.1ghz its still most powerfull CPU on the market, but its your way.
I believe you can disable thermal protection in service menu.

Thanks for your advice to check the service menu in more depth but I didnt see the option there. I wouldnt really want to disable it if I could since it does have a use (I'd rather my battery didnt overheat and explode or something ).
Unlikely that there is something wrong with my unit. The lags arent choppy, per se, but more fractional delays that werent there before the upgrade to JB. I probably would not have said anything if I hadn't seen the phone's prior behaviour. And yes, it is my way - I like things to function as they were intended regardless of whether the current performance is "good enough". Lopping off the top multiplier almost entirely seems like a crude way to regulate the operation and temperature of the phone [.. but the new information below suggests that this isnt intentional...] . If I have to compromise at some level, I will gladly take this (nearly imperceptible) loss of function for the improved battery life I am seeing in this ROM.
Update: the weird frequencies I have been seeing have been reported by others using the same rom as me. It seems to be related to the kernel.

Here we go. Just installed setcpu to show you the service settings works. Also im able to set 100% brightness whenever i want.
I used to underclock cpu on ics, but someday ive realized LTE eats battery 10x times faster, so everything ive done with setcpu is kinda useless.
So i just dont care whats going on with cpu freq since it still lighting fast.
Also JB doesnt lag even on old 1ghz devices cause of triple buffer and forced vsync. I think you still should check your phone.
p.s. Latest F180K official rom

Thanks again for your advice, although that screenshot has nothing to do with the service settings and JB does lag quite a bit on older 1 Ghz devices, as I can attest by having JB running on my Samsung Galaxy S. I reinstalled JB as cleanly as possible and manually reinstalled all my usual apps from the play store and the lags seem to have disappeared. Maybe there was a problem with my recovery softare ? I edited my earlier post to reflect this, but the change in CPU frequency is still there.
As I was trying to say before, you and I are using different phones and different roms. It seems to be a recognized quirk with the rom I am using that while the phone is unplugged, the cpu frequency and screen brightness are very heavily regulated (cannot run @ 1.5 or full brightness even while phone is cool; goes away when the phone is plugged in). Please do not start telling me that 100% brightness is as unnecessary as 100% cpu frequency (I dont ever use 100%). I think you and I will just disagree on acceptable limitations of capabilities, even if I agree with you that they dont affect normal phone use at all. I see it as a mystery that needs solving.
And I am glad to hear that your phone works so well with the official rom . I could wait for official JB on the e973 but I'm impatient and Houstonn did a great job with the port.

So your phone's service menu doesnt have the High Temperature Property and the Thermal Daemon disable buttons?
You still can ask someone to disassemble korean version service menu to find the flags so you can use it on E973

some users have this issues its difficult to know what's the problem sometimes its battery or firmware maby hardware issue. try this use mi1 firmware best stable no issue for me. why I am saying this because I update my phone to mj3 and after that my phone get heated slow charging. then again I downgrade to mi1 firmwear now I don't have any issues

Then your phone is staying or jumping to max frequency 1200MHz too often. Make sure whichever app you are using to control your CPU settings has minimum frequency set to 312MHz, if that's not an issue, change your governor (I'm using "Interactive" governor at the moment). Governors handle how often your frequency will jump to the next higher frequency. You can find out about each governor available in our phone by a simple search on google
If you don't have a CPU settings app, you can try No-Frills CPU Control - one of the most common apps for CPU control, with a clean and basic interface

Above method would work regardless of stock or custom ROM, you just need root.
Alternatively, you can try using one of the RAM/Memory cleaners that don't require root to clean the running processes to keep your RAM empty. If there aren't too many processes using your CPU, there shouldn't be any reason for it to get hot :fingers-crossed:
