[POLL] What's Your Overclocked Speed?

You might have already figured out that HD2 can be overclocked as high as 1.5 GHz on its powerful Qualcomm SnapDragon Processor. Many people run their devices on default clock speed, but there are few of us who overclock their devices to get max out of it. So i have started this thread to know what your max clock speed is and what governer are you using. Post replies below. Also, don't forget to mention your Phone's Temperature if available.
Mine: 1.2 GHz On SmartAss Governer , Temperature Usually Around 95F

1305MHz using interactive, temp alway @ 28°C even when phone get hot?? tho alway careful to let it cool down when it feels too hot.

I have underclocked ... to 720Mhz (interactive)
Performance is okay and saves battery live
Temperature is about 28 celcius.

1267, 768 when battery less than 30%, 422 when screen is off
On-demand w/screen on, conservative when <30% and screen off
Not great on battery, but good performance an no wake lag
CPU Load jump or whatever it is, set to 30%

Sticks with no overclock
using a rom which is fast enough and saves battery life, Dont see a point that needed to overclock CPU

Undervolted to 576mhz, for better battery life.
Runs smooth enough for all apps, including navigation and games

No overclock for me, don't need it, phone is fast enough as it is.
Clock speed: 998mhz (default), governor: ondemand, temp: n/a
Good enough for me sweet onough on may battery.
P.s. there seems to be no difference(performance wise) between rafpigna kernel oc'd @1.5ghz and tytung kernel oc'd @1.2ghz, when testing on linpack and/or other smarbench tools

[Q] [Opinions] Undervolt Settings.

First off, I would like to apologize in advance in case a thread like this exist and I can't find it.. :/ (Search is down, tried Googling) also, if anyone believes this to be in the wrong forum.
ANYWAYS! This is intended to be a preference/opinions thread centering around your OC/UC and Undervolt settings. Feel free to post your current set-up in Voltage Control (or any app of the like) and what Kernel you are running! I wanted to start this to get an idea of what everyone else is setting their UV and CPU clocks to, and possibly give a few of them a try on my own device. :]
Personally all of my clock speeds are at their defaults except for 1000Mhz @ 1200mV. (-75mV). I am also rocking Genocide v1.0 and getting a decent 30hrs of battery life with pretty moderate use.
Post away!

It is kind of pointless since every phone is different so cannot do exactly the same as others. Most can't do 1.4Ghz and most don't wake from sleep at 100 Mhz. All depends what you use your phone for. Mine runs fine at 1.3Ghz except for some TV apps will freeze.

I believe that would be my point however.. curious as to what other people are running as far as cpu and voltage is concerned. Their success and failures. What people can get away with and remain stable. I, and others, could then try their setup (taking precautions of course; ie Nandroid backup.) And see what we get. Who knows, maybe I might adapt a set up that runs better on my device than my current one.

Yes, every phone is different, but that is just more of a reason to collect data - perhaps a baseline can be established, which would be helpful in determining if a particular phone is messed up or just at the low end of the scale. Right now it is hard to determine if a particular phone's troubles are caused by low quality or by damaged hardware.
I keep all voltages at stock, and don't use any OC - my phone runs fine as is, and the battery life actually seemed worse with UV (and my screen felt hot with the screen UV).

My phone wakes from 100 but won't do 1.4ghz for even a couple seconds before reboot but 1.3ghz lasts about 20 minutes before reboot and 1.2ghz is stable. As for undervolts it can handle -25 on 1.2ghz and -50 on 1 and 1.1ghz -50 on 800mhz and that's it otherwise becomes unstable and reboots. Battery life and performance seem to meet at 800mhz with a -50 undervolt games run smooth too and 12 hours of battery. Oddly enough benchmarks are consistantly higher on 1.12ghz than on 1.2ghz I wonder if I'm the only one?

Just to throw it out there. Aggressive undervolts will do more harm than good to your battery life. By that, I mean you'll drain your battery even more.
Sent from my SPH-D700 using XDA Premium App

I can only use Genocide kernel to get 1.3ghz at stock voltage with since all the other choices are uv'd. My last two Epics were able to handle uv'd 1.4ghz by 50mV but I'm not really complaining as I think this is a new phone they gave me and not a refurb. I currently have 100-400 uv'd by 100mV, 600-1000 uv'd by 75mV and 1300 at stock.

My phone can handle 1.4 Ghz but only with the stock voltages. If I try to touch it even by 25mV it locks up.
Who all has enabled the 100Mhz step? I noticed when I did my phone went into Deep Sleep a lot less by a noticeable amount. Staying at 100Mhz a lot.

Always interesting to hear about all this theory behind the reasons for undervolting OC and UC, then to hear about the issues (at times extreme) some have. I would also like to know who uses the 100 step and if it is noticeably better on battery life than the 200? Unfortunately I am missing out on it if I am. Still running Genocide here, but with 1.0 at -50mv 800 @ -50 and 600 @ -25. Very stable and still at 30+ battery life. Having 1.0 down 75 made me nervous. although I hear people dropping it down -100mv successfully.

Good tip about "aggressive UnderVolting"...didn't know that actually drains your battery more. Might explain why 6 hours into my day, my battery is down to 30% already!!! I had it set at 1120Mhz UV to 1175mV (Stock = 1300)...
So now I'm going to try 1200Mhz only UV by 50...see what my battery life is after this!

Can you explain how this is so? Is this based on any actual research, experimentation, or online documentation, or is this just your own opinion?
Unless your undervolt causes the CPU to hang (I've seen mine start to warm up when it's hung, until a battery pull), I don't understand how providing less voltage to the cpu will cause it to drain the battery faster.

If you change the voltage settings please don't blame the rom developers when you phone bricks...

Galaxy S *Underclock* benchmarks

Has anyone underclocked their Galaxy S? I personally think that overclock is a bit of a placebo effect so I just want to know if anyone has underclocked their phone and if they can kindly share the performance of the phone as well as some benchmarks.
I've seen SGS2 underclocked right down to 500mhz and still running smooth but is that due to the efficiently of the Cortex A9 or because it's dual core?
Feel free to share your experiences and benchmarks.

I think we may achive smooth performance with some minor glitch at 800MHz and some minor improvement in battery.
But i dont see a point in underclocking,1GHz is just perfect for galaxy s.Moreover whats the point of buying so costly device and then underclock it???

Lol i underclocked mine to 100 mhz but it dont run good at all. Ur phone is not running a gig all the time if it did ud loose use up ur battery in like 4 hours, it goes from 100 to 1000 mhz whenever it needs it, you can potentially set it to 400 and it will function but the battery saving wouldnt be that much, i think the screen takes at least half of your battery, since my phone on standby can do like two to three days and i can also kill it in 4 hours playing a game or using gps or surfing the web if anything underclock ( they call it undervolt) to 800 mhz and you will barely notice, your score on the benchmark is affected because most phones gpu is directly controlled by the cpu so undervolting will affect your fps which will give you laggy games or crappy benchmark scores

Galaxy S3 overclocking

Hello guys. I just want to take information that there are many tweaks to overclock galaxy s3 to max 1.8 ghz. If we set to maximum overclocking then is there any risk for damage hardware? Because 2 months before i had nokia n8 & i set this device to overclock & it damaged all board,now its totally destroyed. According to my point of view,sometime i think that nokia n8 has only 680 ghz & due to overclock it run on higher clock speed & so that due to low processor it could not manage or handle the higher clock speed & it ran on heavy clock speed continuesly then overload of processor it got damaged. It is my fear for s3. And i think for s3 that it has higher processor with 1.4 ghz,if i set it to 1.8 ghz then there is no risk bcoz of there are cpu governor. With this,the s3 does not run continues on 1.8 ghz higher speed, governor takes control over the cpu to run on higher clock speed according to their high usage like 200 ghz, 500ghz, 800 ghz, 1.4ghz & so on. So i think i can overclock my galaxy s3 with kernel but I'm still confused & I'm not expert. So plz suggest me to do overclock without any damage fear. Thanx a lot.

If i don't but you know then u can tell me about any risk.

NOTHING is without risk, but a good place to start is just to install the latest Siyah S3 Kernel and run it it at 1.6ghz for the CPU and default settings for the GPU. I tried running my CPU at 1.7 and 1.8 and the it wasn't 100% stable and the temps were to high for my liking. Be moderate in your settings and you shouln't encounter any issues.
http://www.gokhanmoral.com/ latest version is 1.7rc1
That will give you a good performance bump with the minimum of risk (in my opinion).
Other than that installing a bloatware free ROM will also give a nice bump. I personally run Omega V29 with the above 1.6 overclock settings and it lightning fast. :good:

There is always a risk involved in overclocking.
1.8ghz isn't stable for most people but 1.7 is quite stable.
How well your device handles overclocking depends on the quality of the chip you got.
This is down to the manufacturing process, you may get a good chip from the middle of the wafer or a not so good one from nearer the edge.
if you want to reduce heat them you should undervolt the CPU, less current means less heat.
Obviously it isn't good for the hardware in the long run but that's what you gotta take into account when you overclock, I've overclocked every phone I've ever had and haven't had any problems but YMMV.

could u plz tell me that what is the process of undervolt if i undervolt the cpu then it is related to only heat or performence also?

If you use siyah kernel then in the stweaks app that comes with it you can choose how much you want to undervolt.
I suggest starting with -25mv or -50mv and check stability.
I use -100mv without problems but like in said earlier YMMV.
It doesn't give a performance boost per se, but less heat in the chip will mean that it doesn't hit the temperature throttle threshold as easily and that means more performance.
The CPU will begin to throttle (limit clock speed) at around 75c until the temp drops and the CPU is allowed to run at max clock speed again.
Usually you will only hit the temp throttle threshold under very heavy loads, for example repeated benchmarks.

1.7ghz should be alright for a 32nm chip like the exynos 4412 on our s3. HTC has had their One S (with a 45 nm chip) clocked at 1.7 ghz. The lower the nanoneter, the more ambitious you can be with clock speeds. Try 1.6 or 1.7 ghz with default voltage settings and see how that goes

You are using -100 undervolt, that mean its high current & mean if i select 25 to 50 then its less current than 100??? & is there any battery improvement if i select less current mean less heat.?

I am using -100mv, as in minus 100mv, 100mv less than stock.
Less current is less heat and *maybe* battery savings.
-100mv is less current than -50mv.

Antutu and Quadrant, all are just bull****. Just to see their manipulated scores, overclocking does not make any sense.
At ground level, applications do not run anything faster as overclocking alone does not work here. Even if you get milli milli milli second improvement which is just nothing against damage of CPU.
Got it?? now start using your phone as it should be and made for.

Before overclocking you should ask yourself Why you want to overclock. If it's because the phone have some lags there is other(safer) way to solve this problem. Honestly I overclock mine for a while (just because I'm a tester) but the S3 is fast enough for everything. You should see my S3. The app drawer appears (almost) instantaneously. Any games play smoothly etc...
On this phone overclocking is possible but useless. If you want to learn how to overclock just to learn how, search in the stickies for the overclocking guide.

I have tried overclocking and undervolting for the last week now and I can say that overclocking has not made any visible difference to my S3. Overclocking seems to be a nice option to have, but the S3 does not need it. Undervolting on the other hand reduces lag considerably when playing games for long periods. Usually my S3 started to get laggy after about 1 hour of Asphalt, but now it does not get laggy at all. I have undervolted by (-)125.
Hope that helps.

Firstly you need a kernel supporting overclocking... Secondly its fine if u wanna play around with your device... Lastly I would suggest u to overclock it to 1704 MHz max (avoiding any boot loops )....
I would recommend Siyah 1.9.1 (as your Kernel) and "Noop" as your I/O Scheduler... In case ure using Siyah as your Kernel, try using "Lulzactiveq" as your governer...
Furthermore u can tweak the governer if u want more juice out of it....
Try it.....

Fix For Back Of Tablet Getting Hot (Still Overclocked)

I found when running Shadowrun Returns with the ElementalX 1.4 kernel http://forum.xda-developers.com/showthread.php?t=2389022 at 1.944 GHZ the back of the Nexus 7 gets hot. This worried me but I noticed when I installed the kernel was an option to use cool thermal throttling. I tried this and now the tablet does not heat up at all. You need to be rooted though to install the kerne of course not sure if ElementalX 1.4 works with stock though, I'm running the latest CM 10.2 nightly. It doesn't seem to affect the performance of either Shadowrun Returns or Wild Blood, the two games I'm playing at the moment, I still have the GPU overclocked to 487 and the Dalvik etc overclocked at the moderate ElementalX setting. . I think being able to run at 1.944 GHZ on my tablet with the cooler thermal throttling is better then running at stock and I believe that even some running at stock have that issue.
Hope this helps others that have this problem.

That's a good sign as you know the heat is being distributed effectively away from the internals. You don't need to be rooted to flash custom kernel. And setting different governors will have a major impact on your CPU.

You might be right about not needing to root to install a custom kernel though I couldn't find a definitive answer in the Nexus 7 2013 forums. I assumed it was needed from using custom kernels on other devices.
My device gets hot while gaming. When you are doing intense gaming like I am I'm sure pretty much any governor will max out the CPU. I know Intellidemand which I use does for sure.
When overclocking, heat is the enemy and it can damage, crash CPUs and even affect the performance of them. I believe if you are concerned about your Nexus 7 heating up (mine does for a good area between the logo and the camera when not using the ElementalX cool thermal throttling) then my advice is good.
Peace.

Kernel is flashed separately from the ROM. Rooting is only for running apps like Trickster Mod to configure to kernel. Otherwise you can have stock 4.3 ROM with any kernel you want. Heating up will obvious affect performance due to thermal throttling but I was not concerned of damage even when the CPU of my 2012 Nexus 7 got to 80 degrees celsius from running overclocked performance stress test under direct sunlight in a case. If your CPU crashes then it's likely not overclocked correctly. Otherwise if it remains stable under artificial stress test, it will handle any game no problem.

I would really appreciate if someone explain me how exactly this function works?
I mean, tablet don't have fan, so how it keeps the cpu cool, and also what this option does to my nexus in order to keep it cooler?

I would not over clock this device. It us more than fast enough for any Android game.
Throttling does just what the word describes. In basic terms your cpu will be slowed down when getting hot and this defeats the purpose of over clocking.
I won't mention the instability that can be caused or the possibility of doing damage.
Just my thoughts.. To each how own and I do have my I7 pc cpu over clocked big time but it has a huge fan.

I agreed, throttling and over clock doesn't make sense but this CPU is underclocked and it is designed to go higher like the one on the galaxy s4 and the GPU is meant to go higher but due to battery life Google underclock it

When the CPU reaches a certain temperature threshold it begins to cycle down the CPU speed in order to cool down the processor. It makes the CPU start running at lower frequencies to keep it cool.

Exactly, so a quick oc and u got a better processor without worries of damaging the chip

Trickster Mod Thermal Throttling Settings
Hey,
If your CPU is getting hot (especially if it's overclocked and hitting 80 C or near to it) At 1944 the back of my case would get noticeably hot. I still say it isn't good for the CPU. From what I know about overclocking if any CPU gets too hot it can damage the CPU or degrade it over time. I definitely wouldn't want it even getting to 80C before it throttles but I found in Trickster Mod, even the free version, you can set the throttling to custom settings if you are rooted. Custom kernels set their voltages to scale depending on the clock speed which means lower clock speeds, less voltages, less heat. I'd rather keep the temps lower on the CPU then risk damaging the device or degrading it over time. Also you can undervolt the CPU at the kernel different clock speeds so it heats up less. You can run the free AnTuTu Benchmark stability test to see if your clock speed voltages are stable and will not crash your device. I have my CPU overclocked to 1944, thermal throttling down clocks the CPU to 1836 at 73 C, 1620 at 75 C, 1512 at 77 C and 1134 at 80 C. My voltages I lowered and are stable at 1944 - 1087500, 1890 - 1062500, 1836 - 1035000, 1728 - 1025000, 1620 - 1000000, 1512 - 987500. The lower voltages are undervolted as well but not going to list them all here.
Peace,

P.S. When it was posted in this thread you can install custom kernels without rooting it is correct, I recall reading that at one point. Like it was said to use Trickster Mod, change governors or custom throttling settings you need to be rooted.
