Hello everyone,
I am using many different roms since i have my desire z rooted.
The only problem is:
i can overclock to about 1 ghz... everything above it results in a freeze were my screen stays awaken.
Does anybody know what i'm doing wrong?
You can try different governors, and others may have some other tips. But its also possible that 1 GHz is all your CPU can handle. Not all CPUs are created equal. Far from it, in fact. There is a reason why CPUs are rated for a certain clock speed, in our case 800 MHz. That's the speed that the manufacturer can basically guarantee stable performance. Anything higher than that, and all bets are off. The manufacturing process has a huge amount of variability to it. So to see some people getting stable performance at 1.5 GHz, while you might not get over 1 GHz with the same series of chip, is not a big shock to me.
What roms are you using?

I have heArd that CPUs of the same phone can perform different. Mine will run all day at 1.8ghz while others get reboots and freezing when they go over 1-1.2 GHz. It really don't make sense to me but I guess it happens. Just glad mine will take whatever the kernel frequency sets allow lol.

The manufacturing process for any type of CPU is quite variable. They can target a range of clock speeds, but can't efficiently manufacture all the chips at the same exact performance. CPUs actually get testing after manufacturing to determine the clock speed, and are "binned" into various categories based on how they tested. If a CPU doesn't meet the test specs for a certain clock speed category, it will be dropped to the next one down. Its also based on market demand. It completely possible a high performing chip gets labelled and sold as a lower performing one, simply to meet demand.
using the andramadus rom i can get well over 1.5ghz completely stable. you should try that

ok gpu overclock then?
I would overclock my HOX...in a block of ice. Or...well, in real life i dont want to overclock it because it would smoke out in my hand
Overheating is a big problem even without overclocking, imagine it running on 1,6ghz...
Sent from my Renovated HTC One X using Tapatalk 2
Can't really see why you would want to overclock the One X, the phone is blazing fast anyway, 4 cores at 1.5 is enough..
But like everybody else said, the phone would probably burn up..
I wouldnt overclock my device - at least not at the stage we reached now.
Why?
a) As long as there is no way to lower the voltage this might toast your device - its a unibody, keep that in mind!
b) 100 MHZ more would have literally no effect - its a 6 GHZ device, even if you boost it up to 6,4 - you wont notice, it will just drain your battery.
6 GHZ is WAY enough...this is smartphone...I mean...seriously...its got more power than my 4 years old 1K €uro notebook...

well first of all you can't just multiply the frequency by the number of cores. I'd much prefer an actual 6Ghz single core processor over 4x1.5Ghz because it won't have any compatibility and efficiency issues. Assuming they are of the same architecture and power usage of course.
Also the ARM low power SOCs probably don't have comparable number of commands per clock cycle as an x86 high performance CPU, even if it's 4 years old.

i agree.. when the multi-core CPUs first came out intel said doubling the core number would give as 47% boost in total performance (not x2 like apple says as they do not know it) lets assume that to be %50 to make the math a little bit easier..
so basically we can make the math here as; 4 cores at 1.2Ghz (when the all 4 active the clock is 1.2Ghz) gives us 1.2 x 3/2 x 3/2= 2.7 Ghz single core performance.. this value for SGS3 is; 1.4 x 3/2 x 3/2= 3.15Ghz
and here we can say dual core at (X) Ghz gives us (X) x 3/2=2.7 thus the (X) = 1.8 Ghz.. so, if you overclock any arm9 based Dual CPU to 1.8 Ghz you get the same performance "on paper".. if you want to catch up with SGS3 we need to OC it to 2.1 Ghz which is impossible at the moment i guess..
what makes the difference here is the lower loads or multiple loads on the CPU.. corecontrol users probably would have noticed; sometimes when the all 4 core are active the clock is only 480 or 640 Mhz (even 320 sometimes if i remember correctly) .. the same amount of load could be taken care of by a dual core at about 720 or 960Mhz.. but here the quad core system stays cooler with a little less energy consumed (or wasted) (as long as all the cores are in one uni-body structure, putting 2 or 4 single cores phsically together is not the case for our smartphones) this is how apple made sure about the smoothness of the ipad 2, new ipad and the iphone 4s.. they used lower clocked 2 power vr 543 GPUs.. when the load is little they can clock down to very low speeds and share the load..
and also you can always find an emtpy core waiting for new task when the others are busy..
so, long story for short; if we were dealing with a little amount but hard processes, having a single core at 2.7Ghz would be good since the quad core design would not cut one task into 4 pieces... as long as we were not thinking about the battery life and the heat.. but since we are dealing with lots of tasks which all could be handled by 1.2Ghz power having 4 cores is better for battery saving and having an empty core for a new task to run parallel with the other running tasks in the background..
It is OC out of the box I think Nvidia OC them for us and it's already pushing itself at the very edge of what is possible for it to do based on temperature, I seem to remember Hamdir saying something along those lines once upon a time...
Why bother to OC it's fast enough as it is.
---EDIT---
hamdir said:
only faux kernel betas allow OC
big warning OC is bad for the HOX given the thermal envelope
you are risking both you battery and processor if you OC
i know you are used to OC from other devices but those had headroom, it is not the case this time, T3 is operating at its max thermal capabilities on the HOX

in other words Nvidia is OCing its T3 out of box because their chips are designed to survive massive amount of heat (sadly it doesnt mean the battery or other components would survive)

I suggest you flash faux's kernel.
It can oc to 1.6GHZ for most user~
and it support s2W!
I expect many users will be aware of this information, but just in case you aren't.
Anyone overclocking should be aware that this will usually lead to higher power consumption which leads to more heat produced and lower battery life.
Especially if it is necessary to overvolt to acheive higher clock frequencies with stability.
Power consumption is proportional to Voltage squared, so small increases in core coltage can result in larger increases in power consumption than mught be thought.
Needless to say this can have negative impacts on battery discharge time and overall life (due to higher temperatures).
Plus there may be some throttling back of frequency if high temperatures are reached. Also possible that frequency may be reduced to 1Ghz maximum when battery voltage is low (i.e when discharged)
Hope this is helpful (first post here)

CPU throttle starts at 85c with thermal TJ-max of 99c.
also there is many debates about this, higher speed need more power which drains battery, but that said it means work gets faster meaning it can idle faster saving power, same the other side slower speeds save power but take longer to get work done using more power.

it will teach you about Tegra 3 variants.
Flash Faux123 latest kernel to know what variant you have.
You can have 1.5ghz quadcore minimum, except if you have the poor variant0 of the Tegra 3, and 1.6ghz quadcore max if you have variant 3
So the overclocking you can achieve depends on your Tegra 3 variant, whatever the kernel, don't trust the figures in kernel threads titles, they just give the max if you have variant 3. And the majority of people have variant 1 so limited to 1.5ghz quadcore and there's nothing to do about it, no future kernel can change the way your CPU was manufactured.
Just, SetCPU can display 1.6ghz or more, but if you have variant 0 or 1 it will never use it (CPUspy will say 1550 and 1600 are unused frequencies)
Variant 1 can go upt to 1550mhz but not for quadcore, so who cares....! Same for kernels claiming up to 1.7ghz, it's in single/dual core, so once more, who cares?
What is important is what max speed you can achieve in quadcore, nothing else, and the limits are clearly defined by your Tegra3 variant
"all chips are not created equal" was a silly bull**** invented more than one year ago as an easy answer to noobs claiming they couldn't overclock their dual core at their max. Now, on the One-X and because of Nvidia unstable quality"all chips are not created equal" is sadly the truth.
PS: wrong=> to say that overclocking means more voltage, undervolting a custom kernel a little can surprisingly reduce heat when you push your CPU to its max,I can have both 1500mhz quadcore and less voltage than stock, as well as less heat (I was surprised, really, on the Sensation I had always found undervolting kinda useless)
PPS: true=> thermal throttle will always come pretty soon and reduce your max speed......

Your argument makes sense, but unless the governor is very efficient at controlling the CPU speed very quickly, in most cases your argument doesn’t hold true. For example when playing a game or running a CPU intensive application (where overclocking has any use) the processor works at full speed for the duration of the application.
EDIT: Frankly I don’t see any point in overclocking a phone like One X. I don’t play many games, but the few games I have played ran very smoothly. And if people are overclocking because of the (barely noticeable) laggy UI then overclocking is not a real fix anyway. Installing a custom ROM (perhaps JB), a different launcher, tweaking background apps/services are some of the more sensible and effective things to do instead.
No disrespect to the devs who are working on overclocking, but IMO HTC and nVidia must have spent a considerable amount of time and effort designing the CPU and deciding the optimal operational parameters to maximize performance while minimizing battery drain. Therefore anything out of those parameters (in theory at least) should impact either stability, or battery life. Perhaps the values HTC has decided are not the maximum possible values , because I assume they would have designed the phone to handle few exceptional conditions (i.e: extremely hot weathers). But I think over clocking would probably cause more problems in the long run than whatever the little gains you experience in short term. Just my 2c.

A few users in the kernel asked about this subject. So I'm going to answer some questions, and provide some information and understanding here about what a "cpu bin" means (/d/acpuclk/pvs_bin) and more importantly, what it means to us as users.
I'll go ahead and snip my response from the kernel thread to get things rolling here so we can get a basic idea of it, and have an analogy to put into physicality of how this can be compared to something less "mysterious" for the every day guy wanting to understand.
Your CPU bin is the result of your device's inspection and test criteria at the Qualcomm factory. Basically a high bin CPU like a 5 or 6 is a very well made chip and very stable with very little imperfections in the manufacturing process. What this means for a HIGH bin is that the chip requires less voltage to operate at any frequency than, say, a bin 1. This is why you see some people having reboot issues when trying to under volt - their processor becomes unstable with less juice because of less accurate tolerances.
Think of it as friction. If you have a well oiled arm on a machine, and part of that arm's job is to force it's way through an opening repeatedly, and the tolerances on the arm and the opening are just slightly off... Well, for that "more out of tolerance" one to do the same amount of work as one that's parts were machined perfectly, it would require more force, because there is more friction inherently from a less accurate build process. Think of the machine as the CPU, the force required behind the arm being moved to carry out the work as the voltage required in your chip, and the tolerance of the parts as the same - just a different types of parts because of course, it is an analogy.
A higher CPU bin is, generally speaking, a more stable chip. Bus frequency, RAM speed, GPU speeds... Everything is directly related, in terms of stability and capable clock rate, to the chip's bin (or quality of build).
Here is an interesting article that most people will find shocking. Look at the difference is clock rates of low and high binned chips:
http://www.androidbeat.com/2013/09/difference-snapdragon-800-2-2ghz-2-3ghz/#.Uwdf2p_TnqA
Note the example of the HTC One and Galaxy S4. It is obvious that Qualcomm sold their higher end chips to Samsung, while HTC was given the less quality chips. Same chip. Same theoretical clock rate. However, the chips in the HTC One are different in 1 aspect - their build quality, and therefore, their capable clock rate and their stable clock rate.
Click to expand...
Click to collapse
And of course the end of that article reallllyy sums up the bottom line here for those of us who like to overclock:
So, you mean to say I should avoid any Android device that uses a Snapdragon S800 SoC running at 2.2GHz, and not 2.3GHz? No! The S800 is the fastest SoC available from Qualcomm, and the slight difference in performance between the different bins should not affect your final decision at all. The S800 is more than future-proof so don’t worry about the slight difference in clock speed.
However, if you are a benchmark junkie or love to overclock your device, better get an Android device that uses the higher binned S800.
Click to expand...
Click to collapse
It is important to note, that while there is a slight difference in performance (of course at stock speeds) there is a huge difference in stability when you start adding non-calculated variables when the processor was given it's bin number.... over clocking... and under volting - both common things that are added into a device's operation after rooting and installing a new kernel.
A small tid bit of information to think about:
A bin 6 runs the stock MAX frequency with only 950 MV...
A bin 0 runs the stock MAX frequency with 1100 MV...
150mv difference! You can see the example of my "machine analogy" can't you? Less is required, to do the same amount of work.
SO, what does all of this mean anyways? Well, to sum it all up, it simply means that you should be aware of your device's capabilities. KNOW YOUR BIN!
With a file explorer, navigate to:
Code:
/d/acpuclk/pvs_bin
And if you are running 4.4.2 KitKat:
Code:
/sys/devices/system/soc/soc0/soc_pvs
There will be a number there 0 - 6
If you are an overclock junkie, higher the number the better.
A lower number like a 0 or 1 will simply mean that you will not be able to get away with as much overclocking and under volting. You kind of just are what you are. If you are a 0 or 1, or even a 2 and you are overclocking and under volting your device and having reboots... well, luck of the draw. Your chip just needs that extra juice to operate, it is a physically binding attribute. Set, and test. Set, and test. Find out where your device is comfortable and what it can handle and accept it.
There is a lot more information that I will add later - specifically about how the different bins are more or less power friendly.
I hope this sheds some light for those who want to understand this.
For those of you wanting to know the guts (as a result of, again, PMs) Keep reading...
BREAKING IT DOWN - A Tale of Two Snapdragons
The test methods involved in "binning" chips. What I am about to explain is what, quite honestly, few people know. This is because the process of testing goes on behind closed doors at Qualcomm, but is common practice in manufacturing anything mechanical or electronic. Quality Control is why you have these "binned" CPUs. It is basically the result of a set of tests run on the chip to examine extremes in variation of fabrication of the chips. No chip, or manufactured part for that matter, is exactly the same as the next, simply because of manufacturing variables that cause the manufactured design to have slight variations or even defects. The silicon of the chip being exposed to undesirable or slightly out of "tolerance" environmental temperatures, for example, could have an effect on the quality of the end product. It is a very controlled process, and the "process corner" as it is called or design of experiments, it a process used to test, evaluate, and graph the uncontrolled moments of that particular part's manufacturing journey.
All of this translates to robustness of a design. After Qualcomm builds the processor, they want to know how this device will perform under different extreme conditions! Simple logic! If I build something, I want to know how it will handle stress, right? But I don't want to damage the ones I have already built. What they do is replicate these possible manufacturing defects in something called "corner lots". Corner lots have had manufacturing process parameters adjusted according to these extremes. They will then test the devices made from these special "test wafers". Typically, for CPUs, and I know at Qualcomm, they will run voltage tests, clock frequency, temperature.
For voltage, for example, the idea there is to push the device to it's maximum and minimum capability at various clock frequencies, to determine it's stability threshold. Any of you other Engineers out there of the electrical type (I am Mechanical, however) have heard a "shmoo plot" which is basically these test functions graphed as hard data. Based on how the chip performs, it is given a number. A well made chip has less manufacturing variation, obviously, and passes the tests with flying colors, shows very desirable characterization traits during the test method, and is given a bin 6 - just as an example. Another chip does ok, is a little less stable overall than the previous, but is still acceptable based upon the design and engineering criteria, and is given a 0 - barely passing the characterization "test".
So back to the beginning. What is CPU binning? What does the number mean?
Well, based up the pvs tables in the source code, it is obvious that the bin 6's are the ones with less VFP (variation of fabrication parameters) because they require less voltage, and at the same time are clocked higher in the GPU, CPU, and RAM and bus. Less force is required to get the job done. A bin 6 would be comparable to the car you bought that finally took a dump a 300k miles while the other one of similar make, model and year died at 200k. Variation in manufacturing. It applies to everything in industry, not just cars and machined parts made of steel. That is what the tests are designed to do. That is why your voltage tables from one device to the next will vary slightly. That is why one person can run this kernel, and this person can't and why one person can under volt their device 35mv while you cannot.
That is what your cpu "bin" represents people. Simply the physical results of some tests done by some engineers to determine your particular processor's compliance to tolerances as it was being built.
Reserved for images of pvs tables. Note the difference in the voltage tables to the right of the frequency steps.

this thread has been addressed before, and the problem with this is that if you ever flashed a rom on your phone, then the bin number will change to that person who made the rom. therefor, the only way this works is if you never flashed a rom or you have your back up rom. Am i missing something ?

Can anybody with high bin (3-6 lets say) post top and bottom values from acpu_table in the same directory? Just wanted to see how those settings differ at 300MHz idle and 2265MHz full speed to mine with bin 1.

I'm running a 3 and I have the same settings.
300 idle and 2265 max.

Updated post number 2 with images of the pvs table source code. Look at the difference in voltage levels based on the bin number! Quite a difference guys!
Mine doesn't have said folder lol

I am on Project X Kit Kat rom - I used Root Explorer to see if I could locate this - I found d/ folder but I coulid not find anyhting named anything close to acpuclk/pvs_bin
maybe I am looking in the wrong place? Any guidance would be helpful...
thanks

Its not there in kitkat roms.
/d/acpuclk/
Not /acpuclk/
On Kitkat it is located at:
Code:
/sys/devices/system/soc/soc0/soc_pvs
So I flashed Agni Kernel and there is an option to change CPU Frequency. By default it is 1.6GHz so it means samsung created it max 1.6Ghz, How in the hell it can go 2.00GHz???

Ofcourse it can because software controls it, you just specify different values i.e. voltage etc and it can work at hingher frequencies. The only real problems are battery usage (will be higher) and system (CPU) heating... thus possibly shortening CPU/component life....

if so, can I put 10GHz??

TMSC created a 3.1 GHz Cortex A9 dual (the processor in note ii is a Quad version of the same chip) to test out the max speed achievable. No information what type of cooling was used for it. Can only assume that it will require heatsink & fan. For tablets & phones, 2 GHz is the max speed you will see with 28nm.

if it's 2GHz the max speed why samsung sold it as 1.6GHz? or it is because of heat?

Vendors tend to slow upgrade the clock as it gives them more room to add every small jump as a new device. You as a customer are obleged to buy any new devices as quick as possible to sustain revenues.

What "sms2000" said, plus heat, battery usage, stability.... your device might be able to work at 2Ghz but i.e. not for 3 years but only 2 years....
