Overclockable cpu... pro and cons?

hi my wildpuzzle version is 8.0, but i'm waiting a bit before upgrading to one of the latest.
I'm waiting also because i'd like to know a bit more about overclocking the cpu.
On one hand, i'm sure the phone will be smoother and faster, but on the other hand? Are there any problems, or effect i should be aware of?
One more thing, there is a list with 6 different kernels with oc enabled. How do i choose which one to flash? Which is the best?
thanks in advance

pro:
your phone will be faster
battery usage during idle is potentially decreased
cons:
your phone might become unstable as the hardware will be running outside of tested specs
battery usage during active usage is increased
The different kernels all have different levels of overclocking. If you try one and your phone becomes unstable (random Force Closes or restart) try and flash it with a slower kernel (lower maximum frequency).
There is no danger of directly harming the hardware in the phone from overclocking. However if the phone is pushed so far it is becoming unstable data corruption might occur.

ok that's what i was afraid of.
is this (damaging the hardware) a real possibility? Or is it just in theory?
Than is the phone really faster? I mean, is it worth to overclock the cpu (considering the possible damage of the processor and the various improvement)?

Sorry about that...
I missed a "no" in there. I meant to say that your phone will not explode into a ball of fire or otherwise become unusable from overclocking.
If it is pushed to far it will simply hang or crash and need to be rebooted.
I can notice a rather big difference. I mean going from 528Mhz -> 768Mhz. That's almost a 50% speed increase.
If you require a rock solid telephone and do not want to mess with stability then don't over clock. If you on the other hand like experimenting just go ahead and try it.
just remember to make a nandroid backup that you can go back to in case your phone doesn't work properly after installing the new kernel.

if we overlocking the wildfire , can i play divs with rockplayer or auther?

If I have WPR 8.06 installed and the 0050kernel, is it ok to try installing new kernels to test? And if its unstable, just test a new one? (have a previous nanbackup that I done directly after rooting the phon).
* Do I have to wipe everything, installing the wpr everytime, or just update the kernel without having to do anything else? cheers!

The Wildfire temperature will increase greatly in theory.
If the Wildfire hasn't got it in its design to cool that amount then it will damage the phone, same with computers.

You can flash kernels back and forth. You don't have to reflash the entire ROM for that. Just make sure you have a working nandroid backup first in case your phone doesn't want to boot.

Yes, in Theory. In practice computer CPUs have temperature monitors that will limit CPU speed to prevent it from rising to high.
In the context of a phone it will be to hot to handle before the temperature becomes high enough to do any critical damage.
Yes, the life time of the electrical circuits will be shortened but a mobile phone will become outdated. Besides the phone is only active for very short periods of time compared to computer.

with a 768mhz speed?.. i dont think it will result to an intense heat that makes the device unusable.. it will make more heat than usual but its tolerable enough..

@OP
Please post in the appropriate sections. This thread belongs in the General Section not Android Development.

Anyone else's HD2 getting really warm when running WP7?

Is anyone else ending up with a very warm device after a little heavy usage? I've not had the phone many days to determine if this is the way the phone is in general, so if this is the way the HD2 is, just tell me lol.

Noticed that also wenn downloading lots of apps from market with wifi on. The backside is getting pretty warm then. But it cools down as soon as you finished your stuff and do usual things like texting or something. Thats my experience.

Its funny people bring up phones getting Hot. Cause We got a Gig processor, and 576mb ram. If you feel like ur phones getting hot, you know ITs a BEAST. also keeps ur pocket warm in winter.

Yes! Comparing with WM 6.5, when running WM 7 phone is getting warm even just scrolling in menu for a while. Battery usage is HUGE! 10 minutes playing game (Jewels) consumpted a half of fully charged battery. Battery life worse then android have.

Yep defo gets hot, when screen is off its fine but when in use it gradually warms up
This is usually the sign of high battery drainage
i used to get it in android

Am I right in saying that magldr could have something to do with the battery drain? Been reading some comments that suggest its possible

you are right, but this only happened to me when i installed andoird via nand way, i don't have any problems with wm7 on my htc hd2 tmobile leo 1024.
i'm happy

my HD2 gets hot when android runs ... WP7 is no load at current bulid

Must agree, my one got realy warm after me sitting 20 min on the train sorting/linking contacts. got more warm that it should.

It just seems like a gradual warming on mine, it can get quite warm though, it happens even if I leave the screen on while magldr boot options are on and nothing else, I think my problem is that, and I'm looking forward to a update

nah just when i'm charging.
EDIT: I did notice bottom of my HD2 getting warm now that you mentioned it. But nothing toworry.

Yea that's your processor, and it is something to worry about, if you care about your phone.

is it possible related to sdcard?
if I use sdcard class 2 or class 6 will it got any different?

Ya mine too becomes ho....if i use internet...otherwise it stays cool...
God knows ...its harming the processor or its just usual thing.

M-SD Class 10 better
Try to M-SD Class 10
It's work well.

When i used to run WP7 and 7.8 the most heat generated was from 3g/2g mobile internet. That thing just fried the HD2's bottom, i couldn't chat on whatsapp more than 5 minutes before the phone's bottom got too warm to even hold. I figured its the combo of SD-card usage, mobile internet (a bit less heat when on WiFi) and screen-on effect that strained cpu and other phone parts to its limits. Eventually moved away from WP (sadly) due to lack of certain things i needed, but i remember that was something that really bothered me alot (aside from no wifi on standby).

[SOLVED] HD2 Gets Warm - Very Warm With Some ROMs

First - If there is thread like this already, I missed it, and please close this one.
Does anyone else experience your HD2 getting very warm when running NAND roms? I dont have it with all builds so that leads me to believe its not magldr. When using GB or CM builds the phone does not get too warm but it usually happens when running an app, like a game for to long. With Sense builds the phone gets even warmer when running apps to long and sometimes when charging the phone. Maybe it is just me, maybe my phone is jacked up, maybe others have this issue??
Any thoughts???
Thanks

Some devs overclock their kernel/builds by default, that's probably why. Underclock it w/ setCPU and it should be fixed.
Edit: charging always heats it up more by the way, that's normal but can be dangerous in combination with high, overclocked activity and other stuff such as tethering.

i have setcpu running and keeping 998max. you think this should be set lower?

Lowering will probably decrease temperature, but less than 1Ghz shouldn't be a problem actually. Are you talking about a lot of heat? CPU's produce heat, and Sense is generally more resource intensive, it's not unusual to feel some heat production, it's oniy bad when it becomes too much.

its not a burn my hand kind of hot. but its not something im used to with this phone. its pretty warm sometimes, i get concerned to the point i will turn off the phone for a bit.

Sense roms tend to produce a lot of heat... I use Cyanogenmod7 and it doesn't get as hot

If normal usage doesn't produce any really noticeable heat, your phone is probably doing just fine. Switch to a non-Sense build if you don't feel comfortable (less heat also means less battery waste by the way), the new Gingerbread UI beats the rather cliché and plastic-looking Sense UI any day imo. Combined with the extra features and speed of GB/CM, I know what I'd go for.
If you're just keen on the Sense apps and widgets, they all have their alternative. A little googling will certainly help you out on that part.

The radio was causing the heat issue. Had 2.15 and changed to 2.12. I even getter better signal....go figure.

how do you set cpu lower than 1ghz?

with setcpu or any other clocking tool.

[Q] Heating Up

Hi there XDA people,
i sorta have a problem. I am using the NAND version of the HD2, the hyperdroid rom. . its working perfectly. The problem is that the fone heats up. the battery is life is ok but the fone seriously becomes VERY hot. its not rebooting or freezing or dropping calls like said in the other threads, just heating up. I have tried MANY roms but this problem still persists.
Any fixes??
Thanx alot

Is it getting hot while downloading something? is it getting hot while charging? is it getting hot while just sitting there doing nothing with the screen on? is it getting hot while in standby? What do you mean it becomes very hot?
While using your phone for playing games or intense heavy downloading of large files its normal for any electronic device to put off heat as it is running a lot of proccess through the internal electronics. If its getting hot while just sitting there doing nothing or charging or while in standby, then in 99% of the cases ive seen with any phone, your battery is shot. Despite you getting decent battery life, it still can be shot just because its getting hot. Over time your battery life will drop drastically.

Soryy
sorry man for not mentioning, it gets hot while doing anything. When playing games, it feels like an oven. When charging it does get very hot. it gets a little hot while the screen in on. But there r no problems in functioning, i mean no reboots or that sorta stuff. So shot? i gotta get a new one?

Well while playing games it feeling like an oven is actually normal.. and while charging. But while just having the screen on and doing nothing it shouldnt really get hot at all as the CPU is under no load or a very light load. And by shot, i meant the battery not the phone. a new battery is like 12 bucks from ebay. But it seems from what you described to be normal.
However, you may have a process in the background chewing up more CPU than needed. Download a task MANAGER not killer, to be able to view all the running proccesses. I like and recommend system tuner pro but there are free task managers in the market. once you have that filter the list of running services by CPU usage, the most being at the top. Secondly, download a battery monitor tool from the market, but one that has a tempuratrue option. So you can see the temperature values of it under the different situations.
Right now, being wirelessly tethered, with my phone on the window sill (so its getting some cool air from outside) im at 37.0 degrees celsius. Sometimes when playing high res games(temple run) for awhile i'll reach 41-42 but i cant recall seeing it higher than that.

ok THNX alot
Thank you, uve helped me alot. so charging and playing games, getting hot is normal and ive taken notice of the battery moniter programs. Thanx. At standby, it gets just slightly hot, i mean its hot here in pakistan, maybe cus of that? anyways ill buy a battery after a few months maybe. Thnx Alot

Ah didnt realize you are in pakistan, so yes if your phone is in your pocket or its just generally hot out, then well yeah the phone will be hotter. After further discussion, it seems like everything is normal. But just keep it under watch, not that your battery bursts inside your phone lol take care

You can try switching kernels or undervolting to reduce heat.

Thnx for the tip. will try

[Q] Freezing issues

Hi i have flashed many nand roms to my hd2 the end result is always the same. phone works fine until i try to play games anywhere between 30s to 10 min and the phone freezes up and is unresponsive. only way to fix is to remove battery. any ideas on what this is why it happens and how to fix it.

what is your ROM? what's your magldr version? what is your HTC HD2 type EU or TMOUS? What is the name of your games? i need more information sir..

I'd hazard a guess at it being an overheating problem. Do you overclock on the ROMs you use? Does the phone get extremely hot? If yes to these, try not overclocking and see if it works.

magldr version is 1.13 and it a tmous hd2 running nexus h2 ics 4.0.4 cm9 hwa v1.2 by tytung. not overclocking running at the standard max of 998Mhz min somewhere around 200. the only option i have used is in the performance settings under memory management i ticked the kenel samepage merging which seems to have reduced the amout of freezing i am experiencing. tried playing the game called drag racing think is by creative mobile. phone on its own works great but even playing angry birds anywhere between 5 to 15min it freezes. noticed yesterday my battery was low so the charge light was flashing and when the screen frooze the light still continued to blink but the phone was totally unresponsive. Any ideas

I have similar problem. But not so often. He is not overclocking, neither do I.
I also use zRam 26%.
This often happens when the phone is under load, so I think that maybe this is due to lack of memory. The phone heats up when the screen freezes.
Any tips?

OK, this might sound stupid but try putting the phone in the fridge for a while to cool it down, then play. Obviously don't do it for too long, it is after all a phone, but I read somewhere that this had helped someone with overheating. I doubt it is a RAM issue cos that wouldn't cause a freeze, it would probably result in the launcher being killed to free up RAM.

not sure putting it in the fridge every time want to play will be quite the fix i am looking for. Might prove the theory that the phone is overheating but then there must be a setting somewhere that can be envoked to get this to stop happening

Yeah I know it isn't a practical solution, I just meant it to test my overheating theory. Perhaps there is a fix, but to be honest if you aren't OCing then I really don't know why it should be heating up so much. Sure, mine gets warm but even when I've played for around an hour on Contract Killer: Zombies (fairly graphically intense and a very fun game) it doesn't shut down or anything. There IS a hardware fix but it's quite dangerous and requires a lot of expertise and the right equipment, neither of which I have Should you wish to try it, just make sure you're very careful
