Safety of overclocking

I've using Apache's kernel at 230-1228 and liking the snappiness with ARHD 3.2. I tried it at 1459 MHz and enjoyed it. My phone seems to stay stable over long periods of time on high clock speeds and doesn't get hot.
I'm wondering, battery life aside, is it generally safe to run the CPU at 230 - 1,46 or even 1,61 GHz ondemand as my standard profile?

It varies from phone to phone, but I have been running mine on BUZZ SENSE 1.3.1 OC+ at 1.61Ghz for about 2 months with no issues, if your using setCpu, set it to 1612Mhz but dont enable set on boot, so if your phone disagrees with it, you can just reboot and it will go back to normal. Do something intensive on the CPU e.g. run stress tests every few hours, If it all goes fine a temps don't go above 35 Celsius (ish) then your good to go and you can enable set on boot.

I'd say it's safe.I have overclocked my phone @1.8GHz using LeeDroid's kernel and never looked back.I haven't found any difference in battery life(Maybe because I'm using smartass and have undervolted quite a lot)and performance-wise it's adorable.Snappy and fast as hell.I also haven't seen temperatures higher than 37.
The bottom line is that it comes down to personal preference...So it's your call!

Thanks for the replies guys, 1,61 from now on I think

SetCPU works for me. As stated, no damage has been reported from it. I'm using it in smartass mode, so it umderclocks if I don't need the excess power. Saving me thus some battery life.

I use my DHD with MIUI 1.3.11. and can switch clock between 122 Mhz up to 1.8Ghz. Can't set it higher other than 1.6ghz because of freezes. But using smartass 122-1.2 Ghz saves a lot of battery and gives much power when needed. Overclocking is not so risky I think.

I see a lot of people using the smartass governor, but I found it really sluggish coming out of sleep. I prefer ondemand with a screen off profile at 230-460. It seems much, much snappier and I haven't noticed any difference in battery life after trying both ondemand and smartass for a few days each.

Hmm, I heard of that, but my phone reacts instantly when unlocking the screen. No lag using smartass.
Sent from my HTC Desire HD using XDA Premium App

I think the main reason I get lag coming out of sleep is because I usually have music on in the background, and with smartass forcing the clock down to the min value when screen is off is causing it.
Would a screen off profile take precedence over the smartass gov?

OC up to 1.5ghz should not damage your phone.
If you take a look at the HTC Flyer, you can see that it has the same cpu as the DHD, but it's running at 1.5ghz.

What is overclocking?is it harmful or ADVANTEGOUS?WHAT is its basic use?

Sent from my HTC Wildfire using XDA App

Overclocking is setting the processor speed higher than it is meant to go, if overclocked too far, it can be dangerous, but usually it improves the overall speed of the phone.
691MHz/710MHz are probably the best and safest Max speeds to go with, on my kernel I have 633MHz as default Max, but it can be overclocked higher to a very unstable 800MHz.

How can i overclock my htc wildfire? please help..

If u r having cyanogenmod7 then goto settings,cyanogenmod settings,performance,CPU and there u can overclock it

Over clocking is good!
Over clocking can be harmful in the sense that it can make your device unstable if you over clock at a high speed, although there are benefits to over clocking such as increasing the speed on your android device to attempt to reduce things such as lag on low end devices such as the HTC Wildfire (Buzz).

Use Rom Toolbox (its downloadable from android market for free or donate)

i have also underclocked my processor as well as overclocking it so that when the phone is idle, it uses less batteryto keep things going.
one bit of advise, dont just max things out. start low and increase the OC slightly, test for a day or day, if everything seems fine, raise the bar until things become unstable, like the launcher jumping or sceen transitions becoming glitchy then reduce by one stage and this will be your optimum OC speed.
My phone can OC to about 791MHz but i'm only set at 652MHz. And the stock UC was about 400MHz and i have reduced to 264MHz

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 )

Does undervolting really lower performance? You're sure you're not thinking about under clocking?

I predict a "my HOX isn't working right, I blame HTC" thread shortly after you try this.
But really, what are your expected gains from doing this?

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'm uv @ 1137 and oc @ 1.6 using arhd 9.1.0 faux 006u kernel and the phone is running better than ever
I use mhl hdmi with sixaxis and the battery used to die in a hour and it got really hot but now I played for a hour before work and it used 40% battery and it was warm but not overheating
But before u go playin around with things look into it all cores are different and behave different
This thread will tell u everything it even has a gragh on wot chips can do what

How much is safe for overclocking?

I'm running Blackout v3.0, and it's running pretty smooth at first. But now my phone is stuffed with bunch of apps, making it running slower and slower. I want to keep those apps so I'm willing to overclock but I afraid of damaging my phone. So I would like to ask what's the safe overclocking frequency? I want the optimum frequency, fast enough and safe/stable.

Any overclocking can be unsafe as it can shorten the lifespan of your memory and CPU. But with that said I run mine at 1200 with no issues. Most people don't go higher than 1600 but anything 1400 or lower is not going to burn it up too quick IMO. Everyones hardware will react differently though.

They usually say phone will get damaged, but I think its a myth. You can go up to 1600. After that it will get unstable.

I run IceColdSandwich and have found 1459MHz to be the best combo of performance and stability on my phone. Every phone handles OCing a little differently, some can reportedly take over 1600 without a flinch and others will lock regularly with even a slight OC. Just experiment with the "set at boot" option turned off until you find something that works reliably on your phone.

Is it true you guys aren't seeing ill effects on your battery by overclocking like that?

I think OC can affect battery drain only if you use an application which utilizes a full cpu load. But, if you're using this app in normal mode, economy will not be great also. So, when you using your phone for calling or general usage you will not see any problems with battery discharge.
I'm using DHD with Blackout v3.0 and I set 1200Mhz for maximum cpu value. I have no problems, phone is stable. Some time ago I used Leedroid ROM and set also 1200Mhz, but phone was rebooted by itself very often. More than twice a day.
You should try to use OC, as someone said above, without "set on boot" option. I think there is no danger for hardware up to 1600Mhz.

Not under normal use. There's a school of thought that says even though the increased speed requires more power, it can also finish tasks and go back to sleep faster, so it ends up being a wash. I've overclocked all three smartphones I've owned to date and haven't experienced any significant difference in battery life.

They say that as a precautionary measure just as they say flashing a custom ROM can be dangerous. For people who don't know what they're doing. But precaution aside, just like you said you can go up to 1600 MHz safely on this phone. I know every phone behaves differently but on average no one has issues upto that frequency. But above that frequency the phone might be unstable. The CPU will be drawing much more power at high frequencies and will heat up more. The CPU heating up too much and too frequently reduces the life of the CPU. So it's not a myth.

i think what i am doing is called underclocking , i am just making max clock speed 1 ghz

that sudden rebooting means you're doing something that crashes your phone... probably the underclocking that causes this.
bit weird though as the hox has many speeds at which it can run, 1ghz being one off them.
Are you sure you didn't also undervolt your hox and that you're using an app that is 100 percent compatible?
Try running the hox at standard speeds to make sure it's not a hardware problem and using an other app to make sure it's not the app causing problems.

I am using set cpu ,but i tried to uninstall it and so far so good but whats awkward is i always use set cpu and this problm never happened .. and about the undervolting i dont even know how to do it.
Sent from my HTC One X using Tapatalk 2

strange, but as your not experiencing any problems after uninstalling set CPU it probably has something to do with it... maybe it's a wrong setting / are you sure set CPU is compatible with hox?
Try contacting the programmer of set CPU about this, or try another tool.
undervolting means setting a lower voltage than standard for your hardware, in this case the CPU.
This makes it spend less energy and thus generate less heat. Undervolting can be used as a battery saver (use less energy) just as underclocking.

Set CPU doesn't support the hox, system tuner does however.
