ive been liking android so far and because overlocking is so simple ive been wanting to try it to hopefully squeeze a little more performance out of the vogue
i just have some questions
whats the highest safe/stable speed?
ive heard some have gone up to 550mhz and quite a few that are at about 500mhz just wanted to know the general consensus from vogue users
my next question is if i clocked up that high should i be worried about heat?
thanks

Every CPU is different so this can't be answered. Your's may not overclock 1mhz, it may overclock 100mhz. You just have to try.
Just in case you are interested.
The clock speed must be a multiple of 19.2 so the available speeds between 380 and 600MHz are:
384
400 (because it uses a different pll)
403.2
422.4
441.6
460.8
480
499.2
518.4
537.6
556.8
576
595.2
Other values will be rounded down to one of these.

Stable speed is ALWAYS device-dependent.
Some chips have minor defects (just a fact of manufacturing).
NEVER, EVER just shove it to 550Mhz. Best case your phone will crash. Worst case your phone will burn up.
General rule of overclocking:
1. Increase the clock speed 2-5%
2. Run an intensive app (there's a benchmarking app in the RogueTools trhead) to see if the phone crashes. Run it multiple times (or continuously) for a half hour with the phone plug in.
3a. If it doesn't crash, go back to step 1.
3b. If it crashes, go back 1 or 2 19.2 Mhz steps. This is your stable overclock frequency.
For the 2-5%, as mentioned above, just do every 20 Mhz. Set it to 420, 440, 460, 480, 500, etc.... I wouldn't go past 540.
Dear All,
I've created this thread with the hope that fellow Nook Color users will share your undervoltage setting of you Nook Color!
Please user the following format for easy reference
CPU clockspeed - voltage
Here are my voltage settings!
300mhz - 1.0v
600mhz - 1.1625v

It's fairly likely that undervolting the lower frequencies does almost nothing for power save because that's when the CPU is in sleep states anyway and partially powered down. It'll make more impact when the CPU is busy working on something and high clocked. But still the LCD is the main user of power.
Undevoltage does help with battery life

Hi Swaaye,
I don't agree as I have personally observe an increase of 30% battery life through undervolting, especially to lower frequencies.
Through SetCPU, I know that the CPU of my Nook spends around 67% of it time at 300Mhz, 15% of the time at 800Mhz and 7% at 1200Mhz. By dropping the voltage at the lower voltage range, I do actually see much improvement in my overall battery life.
Regards
Stanley Lim
It's much more likely that you changed something else to cause a large battery life improvement like that.
-Wifi disabled
-Differences in GPU or DSP activity
-Lower screen brightness
-Bluetooth disabled
-Less CPU usage overall (fewer background apps)
If you want to prove me wrong feel free to run several full battery cycle tests with identical usage patterns varying only voltage.
been running with these settings for about 2 months now and has been vary smooth and stable. battery life has also been vary good. over night 7hrs only 1-2%
interactiveX / 16 bit
225 @ .8125v

How has your battery life and performance been?
I'm curious: How do these overclock/undervolt settings for the NC compare with the stock NT?
hi folks, thinking about leaving oc on permenantly (1200 mhz) I an aware of the dangers, but thought about getting some facts, my question is, how long have people been running art 1200 mhz without any issues, how many weeks or months?
Sent using TCP/IP
1200mhz refers to the highest clock. Your phone doesn't stick to that frequency all the time. It generally scales from 100mhz to 1200mhz. It doesn't really matter if you overclock your device except for effects on battery and I don't think there would be any effect on the Hardware as much as that of an Overclocked computer cpu and considering the average number of months people tend to use their mobile device before getting a new and a better phone.

my phone spends approx 20% of its time at Max freq, thats 1/5 th of its time. I think there would be more potential damage than a computer cpu as these have much better cooling (fans), I just want to know how long people have run at say 1200 without any issues.

Longest time: two weeks ... whitout problems ...
I'm been overclocking my SGS for over 6 months now, no issues at all.
"Standard" voltage values seems to work fine on my device (1350mV at 1200MHz, 1400mV at 1300MHz) but I've tried to undervolt a bit more than once and had no issues as well.
Bye
There are absolutely no dangers in OC/UV. The worst thing to happen is a freeze or reboot once in a while if u go too high. I've been having 1.5mhz w/ some UV for like 2 months and nothing happened so no worries.
Been doing that for about a month now. No problem.
Knowledge is Power. Guard it well.
there are no risks if you overclock your device,but of course depends on how you do it. first of all i would not go past 1300mV which is the physical limit of our beloved hummingbird..of course you can do that,but past 1300mV you are going to shorten the life of your CPU. if you change phone every year then,there's no problem
then if you want to overclock keeping safe voltage values just get Tegrak Overclock,don't activate the "CPU MAX frequency" option,go in optimization tab instead and push up the max frequency by little steps keeping the voltage at the default value of 1275. test it a bit till you reach the most stable one. for example my CPU it's totally rocksolid 'till 1132MHz at 1275mV,no more. but there are CPUs which can archieve better results. then if you want to optimize and save battery consumption you can play a bit with UV on the other frequencies,cheers
Simple question.
My freq now is 633 mhz..still will it shorten the life of my cpu???
Or higher freq and I mean not just for gaming,for everyday use.
Its mainly cuz of 360 launcher.
You need some higher freq to get the smooth look.
So???
Well, I've been using Overclock since the Day overclock came out..
And i have no damn problems .. CPU is still working Great!
And just to let ye know its clocked on 768 MHz ;D
Just overclock it Dude..
Your x8 will be Okay
But if u kept using it for long periods..
it might endanger Your CPU
Also be careful not to fall into a bootloop .. uncheck the Set on Boot option ..
check if it's working alright on 768 .. then check the Set on boot..

Overclocking by 33MHz isn't dangerous, that's very mild.
In General - the more you overclock from the specified values (in case of the X8: 600MHz) the more heat you produce and the more you push the chip to the bleeding edge.
In short: Every integrated circuit has some headroom for overclock as the manufacturer specifies the clock rate at an safe value and not at the very bleeding edge where variances in the chip making process could lead to too high yields because they don't run stable with the clock frequency. In general you don't do your electronics a favor when pushing it too far. 700MHz+ will surely shorten the life span of your phone, how much would need to be seen as there's no real long-term experience.
Wow thanks guys.
You see after some thinkig it aint the cpu freq that is slow.
I set my low freq when in sleep on 245 so the phone is slow on waking up.
When you set it on high the phone will respond better!
like PC, when overclock it may reduce processor life
any clock reduces the life of your cpu. the higher the clock rate less life cpu
A lot of people say that overclocking the Nexus 4 is useless as it's so fast to begin with, but that turns out to be false, yes, it's useless for making e.g. games run smoother, as they all already do, but it's very useful for reducing loading times, and it turns out that the % of time saved is close to the % of increased clock speed.
My setup: Nexus 4, franco.Kernel updater v9.3.3, Franco Kernel #666, Jelly Bean 4.2.2 JDQ39, Governor Interactive. Angry pigs HD 1.1.0 app loading. Fresh reboot for each speed. I did three measurements for each clock speed and left voltages at Franco's defaults. I would suggest looking into the undervolting threads to figure out how low you can go with voltages, undervolting is good underclocking is usually not.
1026 Mhz 1025mV default Franco
15.4s
15.9s
15.7s
1512 MHz 1150 mV default Franco
11.5s
11.3s
11.3s
1620 MHz 1175mV default Franco
11.1s
10.6s
10.6s
1674 MHz 1175mV default Franco
10.3s
10.6s
10.7s
1728 MHz 1200mV default Franco
10.5s
10.3s
10.3s
Conclusion
12.5% faster clock speed = 8.85% faster load time, which means increasing clock speed is 70% effective at reducing load time going from 1512 Mhz and upwards.
40% faster clock speed = 35% faster load time, meaning that people who think running their device at 1026 Mhz is as good as 1512 Mhz are wrong. Nearly doubling clock speed nearly halfens load time.
The reduction in loading time is reduced a bit as you reach higher frequencies, but it's still 70% effective so every extra Mhz helps cut down the wait. Overclocking the Nexus 4 is meaningless in terms of increasing smoothness IN APP, but meaningful in reducing load times significantly and in increasing the responsiveness of your system.
please tell me for saving the battery and still maintaining a little smoothness
the settings to use
i use faux123 kernel.. i just need the voltage,cpu clock n governer settings
so overclocking makes things faster.. really? who would have thunk. and you just found this out?
my brother uses a galaxy s3, and after using it for a few months he tried my n4... he was amused how fast things open and how smooth everything was, and it was all stock frequencies. i think it makes no sense overclocking this beast, it is already fast enough. +/- a few seconds doesnt make that much of a difference but drains the battery significantly more. just sayin'.

Sorry but little OC can help you save more battery in day to day usage. (If you are not playing only games on your phone).

not according to my experiences, and i did play with oc/uc and voltage quite a bit. i always ended up going back to stock on the n4 (not on my old motodefy though) because of the drainage.
So, a 50% increase in clock cycles pushes the performance by a bit.
Who would've thought...?
well that's normal, overclocking = more power draining, more speed; just like with CPU or ram on pc, no rocket science here.

Nope , also OC can (in theory) improve battery life because the CPU finishes its task faster.

But er... Wouldn't it would theoretically need more power and therefore generating more heat than stock frequencies which in turn will have a negative effect on battery life?

It REALLY depends. I'd say most day-to-day usage, an overclock can actually help save battery by 'racing' to sleep (hurry up, finish, drop to deep sleep on cpu AND radio). I think being on 3g makes it even more pronounced because you're letting the radio drop back down to a lower power state as well as the CPU. So if you need to quickly open an email attachment, and cpu is the limiter, it can help it finish, get off the network, and back to idle state faster and save some battery. Now if you go on running benchmarks instead where you just keep throwing more work at it that's a seriously different story. There is also a point of diminishing returns (usually 1 or 2 steps before the absolute limit, in our case about 1670mhz) but in general, a moderate overclock can help.

I agree with u, but remember its a theory.. U finish faster so the time it uses more power is less....
^^Look at the post above me, he got a good example^^
The best of both worlds (if your phone is capable to do this) is when u UV and OC. U would use less power on a higher frequency. Win-win in theory.
But I know what u mean and its hard to believe, but I think that's what @alan1901 wanted to say.
a pigeon delivered this message.... ** your welcome **
If you are lucky, you can overclock using STOCK voltage for the maximum clock.
IE, i see many undervolting their phones by alot. I would just try 1150mV (default voltage for 1.5ghz) for your highest speed (OC as high as you can with this voltage), which means you are not using more power, but still making your phone faster.
Haven't tried on mine, but say 1.6-1.7ghz should be possible with 1150mV for a few at least.
No, 50% OC is not = 50% reduced load time
Let me summarize:
OVERCLOCKING > UNDERCLOCKING FOR THE AVERAGE (POWER) USER
You load a lot of apps, you don't play games or watch videos for hours, productivity is your focus. Depending on use you could save probably 1 - 6 hours a year (see assumptions below). Battery gains won't be significant, but spending less time with the LCD/Wifi etc on could give you some gains as the CPU is one of the lower power drain components.
UNDERCLOCKING > OVERCLOCKING FOR THE 3D GAMER
You spent a lot of time playing CPU intensive games, keeping the CPU cores at max clock speed for extended periods of time. In that case you could get some battery life gains at the cost of responsiveness and app loading times - your call.
IN MORE DETAIL
-------------------------------------------------------------------------------------
UNDERCLOCKING + UNDERVOLTING PROs/CONs
+ Reduces CPU temperature, if that matters to you.
+ IF keeping the CPU at max clock speed for extended periods of time, a lower max voltage could give you enough extra battery life to negate the time lost waiting for apps to load - your call.
- Increased load times - even on the Nexus 4 a lot of apps take > 10 seconds to launch, and don't forget in-app load times, reboots etc.
- No significant battery saving in most cases, potential for loss (if doing a lot of app loading you could even get worse battery life as the screen, wifi etc has to stay on for longer, and the screen is the main battery drain).
- Time spent finding stable voltages.
OVERCLOCKING PROs and CONs
+ Potential small battery life gain, as your device spends less time with the screen/wifi etc ON.
++ SAVES YOU TIME. I'm estimating 1 - 5 hours a year depending on usage.
- Times spent finding stable voltages and clock speeds.
-/- Apps does not RUN smoother.
Why 50% CPU does not = 50% reduced load time and why you test things
---------------------------------------------------------------------------------------------------------------------
It'd be more like 40-30% depending on relative clock speed. I did a simple test as we did NOT know that app loading was mainly CPU limited, could have been memory. And If load times didn't go down there wouldn't be ANY reason to OC and underclocking would be a good idea.
Assumptions behind an estimated 1 - 6 hours saved a year by overclocking
---------------------------------------------------------------------------------------------------------------------
Say that you're on average waiting 4 minutes a day waiting for apps to load, rebooting your phone, waiting for web pages to load, waiting for in-app content to load etc.
Overclocking can cut down that wait time up to 10%, that's nearly 1/2 a minute saved every day, 3 1/2 minutes a week, 3 hours a year. This means you can get a good return on the time it took you to overclock your device, assuming you'll keep it for a couple of years. So if that's the case, why not do it? You'll save some time and you'll enjoy using your device a bit more.
Currently I'm OCd at max 1674 Mhz @ 1225mV, otherwise using default Franco voltages and interactive governor. Stable and very snappy Might be able to reduce voltage and retain stability but this is fine.

I said little OC. Example. Stock cpu clock is 1000mhz and 1000mv. Now, you OC your phone to 1200,1300mhz without changing voltage, or by increasing it a little bit(+25, +50mv, to make phone stable), it will use higher cpu frequency with the same voltage like on lower frequency or with a little higher voltage. So it would finish tasks faster, going to idle faster without getting any heat and give you more battery. On my nexus s and galaxy s3, galaxy s2, i tested it, and it helped (about 30min more screen on time for me). But if you play games a lot and doing some heavy tasks then underclock and undervolt are best for you. But on that beast of phone, i woldnt underclock it beyond 1.2, 1.3, not sure what frequencies are there. If you UC that phone a lot, you can easyly go with some weaker phone.
