How are people overclocking so high?

With Linpack I see people getting to 848mhz and even 1ghz.
I lose stability at 787mhz and I'm ok at 768. I know that different chips vary... but 1ghz difference?
Is there a way to overvolt on the Eris I don't know of?

The eris OC at 1ghz....thats a lie and some one is pulling your leg lol. The eris is not built handle that and if it did reach 1ghz the motherboard would burn up.

Yeah but 848mhz isn't so farfetched. I can do 787 for a while without any freezes. The freezes do happen though.
If you overvolt it shouldn't be impossible to get up to 848mhz.
As for the 1ghz + entries on linpack's site I think it must be another phone running Eris ROM's/ basebands.

I can do 806 all day with Aloysius but my buddy with the same exact setup (i setup it up, so I nkow its exactly the same) can only get stable at 768.
I have not seen anyone with proof or that is respectable, show that they can keep their phone over 806.

"Begin envy now "
I do lol
So there are NO overvolt kernels/ methods?

I can run 806 stable with evil Eris 3, most of the other roms crash when I clock them at 806.

Lucky lol my processor seems to be stuck at 768. 787 doesn't last too long and it's not worth the random FC'ing. I'm sure it would be stable with more voltage and heat hasn't been an issue for me at all at 768 even with Pandora/ Zenonia running for quite a while I haven't gotten even lose 50C.

The question is why would one want to OC that high. I see absolutely no difference in performance at 710 vs anything higher. Probably even lower than that. I just don't see why you would want to run any higher and eat up your battery as well as tax the processor and board more when there isnt a noticeable difference other than linpack scores. Just my opinion but I think all new to OC'ing should be aware that faster isnt always better.

I know that lol I mean... a lot of people who overclock computers don't do it for a performance boost, they do it because they want to see if they can. They won't get better gaming performance they just get a slightly better benchmark.
I want to do it just to do it.

Ok rock on speed demon On that note, I wonder if it could be clocked to the max in a freezer room. If the low temp would help or if it is just hardware limited.

The MAIN problem with overclocking with voltage modification would be heat/ ****ty PSU. I'm sure the Eris battery can get up pretty high, it's a matter of staying cool. I would like to see how high I can get with cooling but I don't even know if overvolting exists for the Eris lol

Dont know about over but I know you can undervolt on it.

If there's undervolting there should be overvolting... someone has to know lol I've tried searching XDA and google but I can't find anything specific.

I tested 710, 768 and 806. I didnt just test with linpack either. I just used apps I normally would run, running for a few days and what not and noticed a difference from 710 to 768 but not really a noticeable diff from 768 to 806. I still keep it at 806 for reasons that my battery life is better. Dont ask me how or why but it just is. I have mine set at 806/480 and for sleep, 480/240. Now most of the day my phone is just in my desk drawer so that could be the reason but i still go a full day with heavy use at the end of the day (bt, wifi, internet radio, run keeper) and still have about 30%+ left when I go to sleep at 10

I have never had a problem with battery lol since overclocking my phone I've only increased battery life. Significantly so.

There has got to be some sweet spot there for OC'ing that gives best perform with least batt consumption. Just wish I knew what it was.

People are getting high because all processors aren't the same. So some can handle, some can't. As for the 1ghz it's a big lie. According to several people including jcase linpack scores can be easily edited and faked. I wouldn't believe anything on linpack that's outrageous.

I sorta figured they wre faking somehow. And I know some processors can handle higher speeds, that's the basis of overclocking. I want to know if I can overvolt my processor.

Can't help you there. Maybe go ask in the IRC? I'm curious if you can as well.

I can hit 787 and run stable... linkpack scores around 5.3-5.4. Oddly enough, my fone refuses to run at 768. I actually have to use a txt file for setcpu to remove 768 from the equation with profiles and the setcpu "trick" my battery life is GREAT. Much better than "stock" even.

Overclocking

Can over clocking the phone can burn or cause damage to the hardware except excess battery usage and does overclock an 1ghz processor to 1.5 will really give a boost or its just a gimmick
Sent from my Desire HD using XDA App

Excessive overclocking really did damage your hardware, depends on the quality.. Overclocking from 1.0ghz to 1.5ghz really give a performance boost, in benchmarking.. In real life, only noticeable in process hungry apps, such as 3d games.. Gimmick? Well, if its a gimmick, it won't give any sudden resets or lock ups.. The processor have a safety switch if the temperature increase because of oc'ing.. If it's to hardcore, for example, 1.0Ghz to 1.8Ghz or even 2.0Ghz, for sure you processor will overheat and lock ups.
Well, mine running at 1.5Ghz, no lock ups or whatever..

You will barely notice the difference in most circumstances. Even if your phone runs fine at 1.5 or 1.8 ghz it will probably reduce the life of the chip over a prolonged period.

Someone Swyped my idea.

I think it will give minor boost at the cost of burning your hardware
Sent from my Desire HD using XDA App

it will help in cpu intensive tasks, that which require lots of calculations, math stuff, 3d drawing done via cpu, faster cpu, better...
in other tasks, don't even bother, there are lots of other things far slower then cpu.
downside, heating, battery drain, increased rate of damage..!

Im using SetCPU for saving battery life. Set the cpu for 384 while screen is off. Noticed quite a difference.

OP, your asking if a overclocked cpu will give a better performance or if it's a gimmick? Really??
Of course it will give you better performance, that goes without saying but the question is, are you willing to sacrifice battery life? The chip will most probably last for years and years if overclocked but 1 thing that kills chips is heat and volts.
I only overclock when I need to and when I'm done I go back to how it was, usually.

My phone is fast enough at 1GHz, dont need overclocking, all games and apps goes fine fine

Most OC kernals are also undervolted anyway so I wouldn't worry about it

to be honest, i use mine with "underclocked" at 800mhz, trying to get at least a half-hour of battery life... i don't see the point in overclock a 1ghz processor, imo, even with a speed gain, the bad side effects easily override the good ones...
i truly believe that overclock my old milestone was the main cause of the problem that happens after...

I'd look at other reasons for your battery life, if it's really that bad.
I'm running at just a touch above 1GHz with no side affects what so ever and get 24+hrs with heavy use, 30+hrs with moderate use and 40+hrs with light use, and that's never turning wifi / 3G off unless I'm in bed when I switch to 2G.
At 1GHz the OCUV kernal I have installed uses less voltage than stock kernal at stock speeds so in theory it's actually safer.

It's not that bad, but it's not so great as yours too. I got about 16hrs with 'hard' use, what is enought most time, but sometimes i get in home with the blinking orange led. Quite annoying...
I try my best to improve the battery life, but i was becoming a battery freak, or something like that, always checking currentwidget...
I get 3 or 4ma at stand by, what is considered normal, i guess... and always use full brightness, hate to use anything bellow...

Full brightness is your problem. I bet it uses like 70% of the current while you use your phone.

going up to 1.8GHz still running stable, thats crazy man!

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

I actually Overclock it to 1.2..

I overclocked it to 1.2 and undervolt the from 800-1.2 -50mV
it was stable.. but then i undervolt -100mV from 100-200Mhz and my SGS crahsed..
I use semaphore 1.3.3... lol any idea what settings i should use ? xD

Is Super Performance Phone Really Important ?

As we can see in many forums, people like to overclock their phone to increase It's performance although overclock can increase battery live and may broke their phone. I think the increased performance can only be felt through benchmark software. The effect on the apps is almost negligible specially on high end phone (like our Note). Why do you overclock your phone and use overclock on daily usage (I understand if the reason of overclocking phone is for satisfaction) ?

Never saw the slightest reason to overclock my phone.

Emulators and because I cannot resist getting extra performance. My captivate was a beast OCed.
Some people don't get it others do...like everything in life. Some don't get how we can live with a phone this big but we do...

On GB (LC2) I overclocked to 1.6gHz and it made everything run smoother (screen transitions, opening and closing apps etc.
On ICS I haven't felt the need to OC. It runs super smooth and fast as it is.
But maybe I'll get bored some time in the future and do it just for something to do...

I'm on stock GB LC1 CF rooted and I OC to 1.55.
Differences when I open apps. They open faster. And not that huge battery life drain because cpu stays at 1.55 a little time and for me the faster app opening matters
*only 2% at 1.55 (not even 1h from 40) - with CpuSpy

Its not bout whether its "important" or not... Its more like, If you can...then why not!? I did overclock my sgnote till 1.6ghz at 1.7 it would reboot.

Its like gettin more for less
Just as Overclock with your desktop, some take a step further by changing heatsink, better ventilation, water cooling, etc.

Exactly, its just free power and if you are not dumb, you are not going to kill anything. This is not the dark ages of overclocking and those fears people seem to still carry from those times.
Take for example on GB running 1.6Ghz Nenamark2 scores me about 34fps or so..Damn close to my record with the Captivate which is 33.5! Then I ran 400Mhz on the GPU and boom..53fps...that is some kick ass gains there. While I will probably run 300Mhz mostly, if I find a game that needs the extra performance, I know I have it there so why not use it.

This is not the dark ages of overclocking and those fears people seem to still carry from those times.

Very true.
On my desktop I have an Intel i5 2500k (original 3300 MHz) OC to 4500 for daily use and when needed 5 GHz.
From 1 year and a half the CPU runs like this and never had any stability issue. And my PC kinda stays on A LOT.
So yes, we don't live in the dark ages of overclocking. Why people STILL HAVE FEAR OF OC!?
These days OC is very easy. Most of the times you can't broke a device / component from OC, because the "drivers" of some microcontrollers from your motherboard won't let you (a lot of protection these days )

Indeed. Plus if you are too afraid then dont push higher voltage, just OC with stock voltage as much as your CPU can do.

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,
KedarWolf
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.
