CPU Throttling

Hi Gang!
I started my HTC journey with the original Touch which at the time was an unbelievable device.
I used to have a CPU throttling utility that would underclock the CPU to bare minimum when not in use and would overclock it under heavy usage.
The result was better performance and lower battery consumption.
Does such a software exist for our HD2? Or maybe it's already doing that throttling natively?

If this is available i would like to have this application as well. It would be nice for the small battery pack.
BTW, would they release a new battery with a higher volt/wattage?
Well, for the app if its out there come to us

Been thinking the same and this should have been included in the device in the first place. I believe Toshiba TG-01 has this. Would help improving the quite disapointing battery lifetime. Lousy HTC...

Idk if Toshiba has it, but still i would go for the HTC HD2 because this device is magnificent. It has it all and you can do with it all. If I didn't got a girlfriend I would do the other stuff with it to hahaa
Well fortunately I got one so don't be afraid for some weird news haha..

Well, I'm not here to discuss HD2 shortcomings, although there are always things to improve with *any* things.
Anyways...
I have looked at CPU throttling utilities for the Qualcomm Snapdragon CPU and it appears indeed that the Toshiba TG01 has such utility. It's not clear at this point if it's an OS-level utility and it seems that it needs to be manually set.
I'm new at xda so I'm not sure whether somebody could port that app for our HD2 and automate the throttling...?
I guess if we're able to develop a HSPL for the HD2 then this is doable as well... provided that there is enough interest in it.
Thoughts?

Have you tried nueDynamicClock?

I'm not sure it supports Snapdragon...?
And I'm actually more interested in underclocking/undervolting that overclocking, 1 GHz is plenty fast for me so far

Yea, I guess it might not support 1GHz... But it is intended for only underclocking, not overclocking....
Idk, it'd be interesting to try.

[Q] The NAND version.

Good morning.
I am new to the world of the HTC and I have a question.
When that version will be available for NAND?
What is the best version of Android?
I am impatient. Thank you
Sorry for my language, I'm french.

Maybe will be available in September, maybe not.
Use search function will be more helpful.

remember use the michyprima's zimage, it pushs my quadrant score to 1817

my mistacke...by overclocking each HW component works much more stable and cooler. I hear temperature is 10 c lower when you overclock hd2

i see your point but there are hundreds of people are using the oc'ed kernel in shubcrafts build yet ive seen VERY few complaints
p.s.
Everyone! i have suceeded in making teh androids run on teh nands the link is -***MOD EDIT- Link removed: Extremely obscene material.Immediate ban placed on this user account***

Problems ? i have E8400 Oc to 4.0 ghz for every day. its 100 % stable with custom cooling .
Thats does not change the fact he is runing much more hotter and more IMPORTANT his life span is reduced very much.
hd2 cpu OC'ed that much with no cooling at all can cause great deal of hw problems in long therm. be sure in that.

11cal cal i know oure problem,it ia because we are waiting for a new shui8 android build......we need some sleep lol...btw,i do not want a nand version,i want a nas version with network share so i can run android remotely haha..

let me also say that overclock is optional. there are optimizations (code is optimized for armv7-a architecture, and other optimizations), but overclock is not enabled by default. w/ my kernel mhz range is 245-998.
Also CPU is downvolted so that means minor battery usage and higher cpu life due to minor voltage.
So why are you saying something that's not true?

@JJbdoggg
@michyprima you are talking about builds ( which only have OC option enabled ) and im talking about alrady Oc'ed devices with such builds

most builds do not have it enabled by default. atleast none that Ive tested. The kernal gives the ability to do it but it isnt set till setcpu is used.
My co-worker has been running his droid fulltime overclocked and has had no problems. I highly doubt any overclocking of phones is that extreme.
If the life span of your desktop cpu is reduced then you are either one applying to much voltage or two using not enough cooling.
Heres more info just to clarify.
http://www.overclockers.com/overclockings-impact-on-cpu-life/

i see i will have to explain some facts about overcloking so everybody understand, so we stop talking nonsense.
Each CPU have its own lifetime , some of earlyer Intel sockets had its lifetime of about 100 000 work hours.
Each time you give CPU more voltage, more than he is supposed to have, he is producing more temperature which offcourse lower his lifetime by certain amount of work hours compared to planed lifetime.
You all talk some nonsense, how some of your friends uses OC HW or phones few weeks or months. if you had time to read my post precisely, you could noticed i said in long therm.
Back again to OC..using custom cooling will only make cpu stable, will not restart or overhear due to over -voltage.
and there is many more factors that is making slighty different situation in hd2 cpu compared to pc...
Negative side is that there is no cooling..only positive side is that hd2 cpu is most of time working on 200-400 mhz depending on the thing you are doing on your phone at the time.
but be sure when you use his full potential, like in multimedia (gaming, playing video ...) in that OC condition, in long therm you are risking to cause HW problems on your phone because of over voltage -missing any kind of cooling that OC 'ed cpu.
my last msg about this.
Cheers

I guess he didnt read my exact post detailing the negative effects and how to determine them... I guess its nonsense even though its factual.

Where is our 2GHz overclock?!? :(

Hey guys,those lucky bas*ards over at the G2 forums have a kernel with overclocking up to 2GHz.Where is the DHD version of it,huh?
Yeah,I know,such a high overclock will most probably damage our phones and battery will go completely all the way to hell,but c'mon!Don't any of you wanna try it?Plus,we get 3200+ @1,6Ghz while the G2 gets just over 3000(something like 3006) @2Ghz in quadrant!Imagine what the DHD will do with 2GHz!And we are supposed to have better quality CPUs!
So come on,dev up!

With the current UK temperatures the only benefit of having a 2Ghz overclock would be a warm hand/pocket.
As a technical exercise/project it may have some benefit, but practically what use is a DHD that will get really hot, really quick. And then the battery dies, or the thermo cut out kicks in.

I would never clock at 2ghz...that's asking for trouble and the voltage would be to risky...no one is going to make a 2ghz kernel for the DHD

Why not?I mean,not for everyday use,I wouldn't do it too!But for some time to do some benchmarking etc it would be really nice!Plus the G2 seemed really stable @2GHz.

Well..I guess it is a matter of risk...
I am no expert, but I can imagine overclocking to 2Ghz, if possible, will require a lot of overvolting and may seriously affect your cpu....for the worse...
Even for a short time, if you are not sure what will happen, are you really willing to potentially give up your phone?

Yeah it can be done...There is a 1.7ghz kernel out..(its a risky overclock so its not for download on the public forums)
You can drive a car with your feet if you want to but that doesn't make it a good idea
2ghz is twice its clock speed...if you really want 2ghz then wait for the dual cores...1.5ghz is the max safe overclock...and even then its not been tested over a long period of time.
Saying the G2 is stable at 2ghz is meaningless.....there are so many different variables, its just not that black and white.

I guess you're right...But there must be someone crazy enough to try!Well,one has to wait,right?Thanks for the replies by the way!
And btw,the G2 requires to be overvolted @1500mV.

which is over 35% more than stock DHD

No!
Using any CPU frequency that is not default ( underclocked or overclocked ) requires testing and manipulating the various variables. The CPU needs to be in sync with the GPU and the other parameters. Needs modifications in the kernel itself. The device is not made to run at those frequencies. You will burn your device, sooner or later.

Yes and device can freeze the most of times.

Xoom performs way better now....

I've had my Xoom overclocked to 1500 MHz for a couple of weeks and I haven't been satisfied with the performance at all, especially with browsing. I just decided to turn it down to 1200 in setCPU and I am in heaven right now. I'm guessing overlocking led to overheating which led to the processor choking? Whats more amazing is I'm getting better Quadrant scores now than when I had it at 1500MHz. Anyone have similar results? I guess its all about finding your devices sweet spot. Gonna try and fine tune it now lol
Running Tiamat ROM 3.1 on Tiamat 1.4.4 kernel.

Any chance this is just "freshly-rebooted" newness? The processor really doesn't heat up that much to go into thermal throttle (haven't seen that pop up in "dmesg" here) so I'm just as surprised as you are.

Doubt it. I don't reboot much lol I did just flash the tiamat rom so I don't know if it made THAT much of a difference but its definitely alot better now. Also, I tried 1700mhz and it is a reboot within a minute ....is that heat related?

Well, that's what I mean- after a reboot (and after the dalvik cache, etc. has settled down) most systems feel "fresher" than one that's been up for any long while (even Android).
So maybe what you were feeling was the benefit of a fresh reboot?

It might have; I've gotten busy and haven't been talking much to BRD but every now and then I'll send him a note of what I've seen with my own custom stuff, and lately I've found that turning the Autogroup Scheduler off actually improves the usability of the Xoom quite a bit. Maybe he did that in the latest Tiamat?

Nah, it's just that all our chips are speced to 1GHz; some can of course go higher (I can run at 1504MHz all day long) but once you go over the limits for a particular piece of silicon, you'll get register/instruction/memory errors that can cause exceptions, kernel panic()s (the Linux equivalent of the BSOD) or reboots. Your Tegra2 just isn't stable at 1700.

Yea, 1500 MHz is pretty stable.....no reboots at all. Maybe its just a fresh ROM installation or reboot like you stated.

1ghz 1.2ghz 1.4ghz 1.56ghz or 1.6ghz

Just wondering what you are all clocked at
and if stable.
Currently at 1.4 myself and running smooth

I don't even know how to overclock it. Does one need a custom ROM for that or does the stock one suffice? Not that it really matters, I mostly just read comics or books or watch movies on my tablet, none of which needs that much CPU.

Greece during the summer can get quite hot, so it's definitely not a friendly place for overclockers, even desktop rigs can feel the extra heat, so for me, overclocking will not happen for another 3 months minimum. Even now, at stock 3.1 the tablet can get pretty hot when playing some HD games.

I'm sure only root is required but I agree - pushing the cores for nothing more than reading, watching movies or playing already tablet optimized games seems like a pointless endeavor and certainly dangerous to the long term health of the tablet.

I am happily running mine @ 1.6 and very stable with no fc. Did have it higher @ 1.7 but had major problems with reeboots. Benchmark above taken with current rom @1.6

Try "StabilityTest" from the Market to see what your device can handle.
Mine ran 2 hours without problems on 1.5GHz but crashed after 17mins on 1.6GHz.
Running the tablet at 1.5GHz makes a big difference, everything is much more responsive and the browser is way faster.

Can you suggest me the right app to overclock my iconia? And what I have to do to set that apps? I had some doubts with options like "interactive, on demand, ...etc". Which one could give a little bit of stability? I can't find any guide on the internet to understand what these settings change, and which one is the better way to optimize our tablet.

setCPU works fine if rooted; you can also use the Virtuous method if you run one of their ROMs; check the DEV sections for more info...

Not sure setcpu works on both cores.
Use the virtuous method it is a new way to overclock and it is faster than using any app...
Lets face it anyone running a rom I am sure it is virtuous something

Thanks Trinnity66 and MJ-12. I think you've finally convinced me to root this device and run a custom ROM.

just in case people doesnt know
the mainboard are stressed on a bench before go outside and get sell
put the mainboard in a OVEN (not yours at home, it's a special OVEN) then after 1 hour at something like 60 - 70 degrees running
All mainboard got an error are returned to check and fixed
but
overclocking does not give you that much improvement...
for sure optimized kernel with slight overclock are running smother than the stock stuck at 1GHz but.... when people are crying to have not enought battery... why overclocking ???? the things who use more battery is the SOC and the SCREEN....
I run for now Stock 4.010.24 with Stock Kernel (I will go back to custom firwmare when all will be ok and stable)
games are running perfectly... when they are dev for the tegra

What the hell are you babbling about and what does that even have to do with the discussion?
I don't even know if I understand you correctly since you're not even trying to make coherent sentences, but if you're referring to components on the motherboard being loose then there's WAY better ways of fixing that than throwing the whole thing in an oven of any kind. You should NEVER fry the whole motherboard just to fix one or two components that are loose, instead just apply a heatgun on those specific components. Besides, AFAIK none of the issues with A500 are related to loose parts...

His post has everyting to do with this thread and nothing about "loose parts" He is refering to the physical conditions the parts are subject to ie......Heat. Which in turn is increased by overclocking the passively cooled processor. Which is not very efficent and can easily overheat. Its ok if you don't understand plain English, but your post is obnoxious...

My english is not high but I think I was clear, proof someone understand what I was speaking about.
I forgot the most important
ARM Cortex-A9 MPCore can go between 800Mhz and 2Ghz if someone find a way to cool it, well maybe the tablet will go until 2Ghz (reducing the battery life a lot, something near of the W500 ..._)
