Hello.
My friend say that he can over clock this thing to 1.5 ghz but i don't believe him.
So what is the maximum clock speed?
800mhz and it's unstable.
Your friend is bullshitting. No way can a lower end single core be clocked that fast, it would simply just burn out.

There is absolutely no rule of thumb for overclocking.
One CPU might handle 800+ MHz (806 MHz seems to be reached by benjamingwynn - nice speed!) and other might handle only 760-780 MHz stable for example. Don't forget that overclocking isn't an exact science. It more like an art!
It depends on many variables: the batch, the place in the wafer where you CPU came from, the voltage you're pumping, the cooling provided, etc.
Some CPU's don't need much voltage in order to scale speed, others need a big voltage increase in order to handle the extra speed. And there are others that simply don't scale well and can only handle weak overclocks.
And of course there is always a theoretical limit.
Anyone who says that he/she can overclock a 600MHz CPU to 1.5GHz lies with all the teeth and is an ignorant, with all due respect.
I know no CPU in the world that can overclock to 150%. Not even with extreme cooling (Liquid Nitrogen or other Subzero solutions) and other crazy mods. Now imagine this on a small device like a smartphone, where you can't properly change the cooling of the CPU in order to cope with the extra heat generated.
The phone would most likely burn in smokes.
I know a little bit about this matter because I have experience in overclocking PC CPU's. I know most about Intel CPU's (Dual and Quad-Cores, still haven't touched a hexa-core...), cooled on air or with liquid cooling.
The PC I work with every day has a Quad-Core CPU that is 3.2 GHz stock (QX9770) and is running at 4 GHz. It can handle more but the extra heat and voltage needed isn't worth the extra speed (and the accelerated degradation of the CPU).
Sorry for the offtopic guys but I had to reply to this anecdote.

All the finetuning (voltages and so on) is done in the BIOS. My motherboard is actually designed for overclocking.
It's an "old" Asus Rampage Extreme.
You would be amazed with the amount of settings it has!
It also comes with Windows software that allows some realtime adjustments but the "core" lies in the BIOS.

Nice OC aigaming! but never forget that CPU's do degrade over time, even if some people tell you the contrary.
If you keep your CPU cool and don't give it too much voltage to "eat", then everything should be fine for a long time. Still don't abuse it too much, this is my personal advice.
You have a nice cooler and with a push pull config it should keep things cool.
Mine is an old Tuniq Tower 120 (copper block lapped by me when I still had lots of patience) with the stock fan changed. I don't use the fan controller that came with the cooler btw.
My CPU used to be cooled on liquid but I have a way too limited case in order to accomodate the radiators, pump, reservatory, etc. Sold all the gear.
Keeping my beast at 4GHz on air is VERY NICE.

I wish the HTC 2.3.5 RUU would have a kernel with overclock option for the CPU...
Anyone available to change the HTC RUU with an overclockable kernel?
Or am I saying nonsense? Probably CRC check would fail and I could only flash it with temp-root, right?
Would really appreciate being able to push my CPU just a little bit more...
The only single-cores I know of that can actually reach 1.5Ghz overclocked are devices running a Qualcomm MSM7x30 (Desire Z) or an MSM8255 (Desire HD/Xperia Play/Sensation XL [stock speed, same processor]/etc).

So I thought about overclocking. I never overclocked any CPU by now. No PC cpus, no mobile cpus
I just always read: Do not overclock! More heat production, more energy costing and of course: probably decrease device life-time and may damage the phone.
On the opposite there is: more cpu-power. WFS seems to be able to get OC'd to 800 MHz (which is 200 above standard and only 200 below Desire)
So, what can you tell me about the above conclusions?
Next question: Do I need overclocking, or is it just to win a p.... length comparing ?
I'm on stock European rom 2.3.5. I know I need custom kernel. which one I could use, how to flash? Which apps do I need furthermore?

No it's not just for a pissing contest.
Jikantaru's new kernel will allow you to set your clock to vary between 120 Mhz and 806 Mhz although 787 Mhz tends to work for those unlucky enough to have phones that freeze up at 806 Mhz.
The CPU doesn't run balls out all the time. It speedsteps as needed to save battery power.
You flash the kernel that you download to your SD card through CWM Recovery's Install zip from SD card feature.
Reboot and you now have Ext4 support for Link2SD, etc, and overclocking capabilities as well as a host of other kernel tweaks to handle memory management, etc.
As far as programs to set the clock with? SetCPU, Rom Toolbox, Nofrills CPU, Antutu CPU, etc.
I would choose "Smartass" as your governor and 120 and 806 as your min and max CPU settings and choose to set it at boot.
That's just my preference.
I personally bought Rom Toolbox Pro and manage the CPU settings through it.
It's got a host of other cool features all in one place and jrummy updates it very often with new fixes, features, etc.
thanks for that.
so what about damaging the cpu or the device? is there nothing to worry about?
and what is a govener? do I need it in addition to setcpu ?

The governor is the method by which the phone plans it's stepping up and down of frequencies. Smartass is a tried and true good combination of power savings and stepping to the plate with high clock frequencies when needed.
No you won't need anything extra. It's one of the settings in any of those programs.
Sorry for asking again:
It won't damage my device or burn the cpu as overclocking a normal PC CPU would do?
edit: using nofrills now. Seems to work.

Overclocking comes with no promises man. Mine's been overclocked since August so that's all I have to go on.
There is always a danger or risk when overclocking. The manufacturers determine the safe frequencies, temperatures, voltage, etc. based on scientific experiments in different environments. However, with that said, obviously, they are not infallable either. The best way to determine your risk is to think about what conditions you'll be using it in the most and what kind of stress it'll put on your phone's internals. Do some research and see what other people have problems with and under what kind of stress was the phone. Use common sense. Things like raising voltage and frequencies raise the temperature of the phone's internals, also. So, in turn, do you also have a case on the device that retains heat? Do you live in an humid/dry or warm/cold area? Do you do a lot of multitasking? Are you constantly on it? Hope this helps.

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?

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
Can anyone develop an app which can set CPU speed in WP7 phones???
probably.
Now, this would be kind of cool!! Especially if i can run my samsung focus at 1.4ghz

I don't think so. My old Omnia HD (Symbian) can be overclocked from 600mhz to 900/950mhz (50% more) without problem, with an elder architecture...
I wish to see 2nd Gen. devices how much can be overclocked...1.8 Ghz will be great! But Wp is the faster OS yet =D
Older architectures are actually often better for overclocking, because they're not running as close to the theoretical limit on the speed of the chip (the practical limit is based on heat dissipation capability, but there are other limits that are more subtle and tend to just result in weird hardware errors rather than thermal shutoff). That said, 1GHz is still probably pretty far from the limit.
I wouldn't oc for my device just to watch the speed of the cpu or maybe just a little bit
I think this will be useful only for device with new cpu with 1ghz clock like radar

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..

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.

only faux kernel betas allow OC
big warning OC is bad for the HOX given the thermal envelope

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......

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......

Nice words and I just won't to add variant 1 can now go to 1.55ghz with faux 07vf I'm currently usein with the lowest most stable undervolt values and less heat than stock kernel and gameplay is amazing also on arhd 9.4

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.

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.

Late reply, I hope you'll read it anyway
I tried faux 007b5, so overclock free too, I had 1.55ghz indeed, but never for quadcore, just for single or dual. Sadly I wasn't able to reach 1.5ghz quadcore but 1.4
With 007u, I have 1.5ghz quadcore, but 1.55 is an unused frequency
Can you check, with tegrastats, if you reach 1.55ghz quadcore or only for 1,2 (or3??) cores?

I tried tegrastats and I got 1.55 4 cores for about 20 sec and then 2 shut of and then ran 2 at 1150 playin dead trigger and on cod zombies 2 cores at 1350 witch I find strange faux 0105b
