Hi,
i just want to know should i be worried about any long-term or short-term consequences regarding overclocking 1.0 to 1.1 and undervolting max -100.
Over clocking can and will shorten the life of your hw. Undervolting for overclockers is to help offset that and get more battery. Straight undervolting is for users who need most from battery and will not shorten hw lifespan, helps with with battery and possibly life of battery since current will be sucked slower from it and it heating up less.
I voided my warranty.
so what if i overclock and undervolt at same time ???
You can uv and oc at the same time. It helps the temps and offsets some of the heat w/o an oc. I highly recommend uv'ing if you oc. Me, personally though, i really don't need oc, but i am trying to be patient for stable build of cyan7. I'm more than satisfied with my battery life right now so i don't want to run into possible problems you might run into flashing a custom kernel. The uv and oc might work, but wifi, bluetooth or something else could be broken and then you have to troubleshoot that, blah blah blah. If you flash a custom kernel, you should stress test your uv's and test all the features of your phone.

Hey, back again on a question about overclock an HTC Thunderbolt rooted with CM7 and Tiamat kernel. Anyways, I can overclock it to 1.9ghz pretty stable and suprisingly good battery life ( believe it or not ), get's kind of hot when charging though about 107 farenheit and 99 on daily use w/o it being plugged in. I was trying to get it to reach 2.0ghz, I know some of you will say its not that big of a jump from 1.9 to 2.0 but that's not the point, I am using SetCPU and Incredicontrol, and I just can't seem to keep it stable because I set it 2.0ghz and put the SVS volt in Incredicontrol to the high which is 1550 If I remember correctly, It's pretty stable but as soon as I press the lock button it freezes up and I have to take battery in/out. Any suggestions ? Thanks.
I'm not the most brilliant when it comes to overclocking (Having similar problems), but you have to keep in mind that 2GHz is double your stock clock speed, so yes, that is a big push. My recommendation is to find a low-voltage kernel that has Smartass V2 and try again.
Hmm wel l i do have smartass v2 but using smartass v1 with 1.9ghz overclocked no problems yet maybe il just stay at 1.9 but then again ill keep trying 2ghz until i get bored lol

...or cook your device. At the voltages you describe, I can all but promise you that you're slowly killing guy your phone. You're talking about a 5% gain in clock for a performance gain of less than 2%. Your phone probably isn't stable at all at 2ghz. Smartass ramps up to policy max at screen on, unless you change it, and it probably locks before the display even comes on. If you like your phone, stop. The return you get probably won't even do 1.9ghz, so count yourself lucky at that. Mine won't run that fast.

What is a safe voltage for 1.9ghz? I think right now it's at 1300-1450 I forgot, SVS(I don't know what the SVS is, just says on top of Incredicontrol). It's very stable and the phone doesn't even run hot, no random reboots or anything like that, but since you said the voltage thing I am worry now, can you explain some more? With my overclock right now which is as I said 1.9ghz, Am I still killing my phone? My battery life is pretty good except when watching videos, goes down very fast but other than that it's good. Btw what are good temps for my phone?

That kind of voltage tends to stress the silicone. If 1450 is your top limit, that's not too bad, but I probably wouldn't venture past that. Your governor is keeping it from running at that speed most of the time. Most of the heat you feel the phone give off is the battery. You really don't feel much of the heat from the CPU. Too much voltage is going to cook your CPU well before it begins to show temperatures on the battery sensor. As far as temps go, pretty much anything under 135F is ok. The battery will be the first thing to fail as temperatures rise. The SoC can tolerate much more. SVS just stands for Static Voltage Scaling, as opposed to HAVS, Hybrid Adaptive Voltage Scaling, which I don't think any Tbolt kernels support.
I don't get the purpose of that level of overclocking. My phone is snappy smooth and basically SAFE at 1.15 or 1.2
My name is Revos I'm a recovering flashaholic running Liquid Gingerbread 3.0

The core is designed to run at 1.5ghz (though the caches and memory arent fabbed to, really) so running at 1.5 or 1.6 isn't a big deal. More than that and you're really challenging it.
First off is this a good idea? can such small devices be over clocked in a safe way without risking damaging the hardware?
if yes which would you say was the best app for doing so?
Hi,
A good idea... maybe, maybe not... it depends on what you want... higher scores in bench?A shorter battery life?A very very hot device while browsing or gaming (if you run at 1.8Ghz for example)?A little extra power for some apps/games?
With overclocking a little (1.5/1.6Ghz) I noticied that some apps open a little faster and the genera UI is a little more responsive...
There is always a (little) risk to overclock our phones, generally due to overheat but also some CPU's can't handle high overclock.
For me I don't remember reading someone burn her CPU with overclocking but...
There are still some software protections before to burn a CPU (thermal throttling, CPU temp limit before shutdown, etc...).
Obiously the duration of life could be reduced mainly if you always run at 1.8Ghz with playing games... So the "safe" way would be no overclock or a little overclock like 1.5Ghz... For you to test and decide...
For the apps: SetCpu, System Tuner... there is a bunch on the Play Store.Just for the CPU settings I would say SetCpu.
For me i will never overclock my cpu. Just install siyah kernel and it's pretty smooth in games. Overclocking will damage your cpu and maybe loose some of the performance.
I can't see the need on this device, I might experiment with uv, maybe even underclocking, but as above, super smooth on siyah, and Slim Rom

Talking about battery life i installed darkys rom 3 onto my i9300 and the battery life is already suffering a loss of maybe around 25%. In saying that over clocking will only cause me to lose even more so ill leave it for now

I'm too running on slim ics and siyah kernel. Best battery life and performance!

Overclocking won't damage your CPU unless you set crazy voltages, or let it overheat. Also, it won't lose performance... that's crazy talk. Only if it overheats will it throttle, but that only happens on large clock rates like 1.8GHz or if you're in a hot environment.
I had my old LG GT540 overclocked with no heat problems mind that was only a 600mhz cpu, had it up to 825mhz.
But we already have a powerful cpu in this phone, foe now I don't see the need to overclock.

The best app depends a lot on your kernel and device. For example, for my Galaxy S2 the best OC was with TegraK Overclock.
With my Xoom CPU Tuner is still the best.
With the S3 I suppose CPU tuner would be alright as well, but I haven't had the urge to OC it, because I find SiyahKernel still quite unstable in the S3.
You need an overclockable kernel in order to OC your phone.
As for damages, it is hard to tell if they are permanent, but picture this: your battery will have to be recharged more often, because it will drain faster. Since batteries have a limited lifespan which depends on how many charge cycles they go through, the more often you discharge/charge them, the shorter their lifespan will be.
Also, there is no telling what kind of ill-effects the added heat can do to the phone. It may be totally harmless, but it may also affect the quality of the display, since the added heat will be right underneath the screen.
The lifespan of the CPU will be shortened: instead of being able to work well for 20 years, it will work well for 18, 17, 15, but more than enough time for us to already have replaced our S3 for organic, intradermal smartphones!
First of all, I am totally new to this forum.(I mean as an registered user)
Before that I always had the thing from the forum what I needed.
Now here is my question,
If i overclock the processor speed of my android device to a higher position, isn't it gonna take more battery power than usual?
Phone model: Xperia Live With Walkman
Boot loader: unlocked
Root Access: Rooted
Kernel: Rage 3.2
ROM: Real ICS r6
overclocking is going to drain your battery obviously.
overclocking drains more battery but gives better performance,too much over clocking makes phone heat & even hardware issues

My phn's original capacity is 1 Ghz
How much overclocking can keep my battery level fair and also give smoother performance without causing me any hardware issue?
Btw, Thx for the ans.:good:

Power consumption = Voltage x Voltage x cpufreq x some constant for your device. If you OC (raise the cpufreq) you will have more power consumption and more heat generation because most of the power is dissipated as heat and the heat is what damages your cpu. It is probably impossible to kill your cpu in one go, because your device should shut off when it begins to over heat (this will look like a random reboot). But you will slowly degrade the over all performance of your cpu and eventually you get to a point where you see a lot of random reboots. So if you decide to OC you probably want to also undervolt as well. This is because power consumption (and heat) scale with the square of the applied voltage. One rule of thumb is that your maximum cpufreq is actually determined by the voltage. For example, my cpu is rated to be stable at 1 GHZ and 1200 mV, so when I OC and UV, I scale the cpufreq as high as I can go, as long as the voltage is not greater than 1200 mV, for me this is 1.5 GHz.
Also remember that your cpu governor will have a big effect on your power consumption and it is probably doing a good job keeping the cpu running in the low range of the cpufreq table, so you are unlikely to see big effects of OC or UV on real life battery consumption.
every chipset is different, even though the brand and model is the same. noone can guarantee you any safe value to overclock.
Thanks Giving!
Thanks Everybody for helping me out!
I am applying 1.402 GHz :laugh:
Overclocking is not the only thing you have to think of in order to improve your phone's overall performance. The most important issue for me is choosing the right kernel and applying the right governor + I/O scheduler. From my experience with Mini (i have tried ALL available kernels and most of ROMs) I can surely say that now with my phone (ICS .587, custom ROM + kernel) overclocked to 1.5 GHz battery with minimal use (20 mins calls, 40 mins WiFi per day) lasts at least 60 hours. When I bought my phone (GB, no OC, all stock) battery was struggling to stay alive for 24 hours with the same minimal use. Conclusion: first pick the right kernel and ROM, then OC.
I do rom flashing and oc on cpu too, the phone sometimes get very warm. Just wanna ask is the heat affecting the battery to get 'fat' ?
Im not sure but what you can do is get a kernel which can undervolt and therefore you can reduce the amount of heat it produces.
Not really recommended to undervolt unless you're really an advanced user. Underclock is safer. Heat reduces battery life overall..
Pls what is the best values to underclock big and little cores to reduce heat and not lost too much performance. I would also like best tweak settings for interactive governor. I am scared to mess things up myself, so i am asking the pros.
I love this phone and i just want to bring out the best in it. Running on XPower v5.
