[Q] Safe Overclock - Desire HD Q&A, Help & Troubleshooting

What is the highest MHz that i can go up to without risking my phone too much? My ROM and Kernal lets me go up to 1920 but thats probably not the best idea.

you have reason.... NO GOOD IDEA lol
in a kernel thread (a lot of time ago...) i was read... that was not recomended overclock avobe of 1600 Mhz... And atention important!!! don´t underclock down 170Mhz more or less (because can be the devece cannot exit from standby mode when you unlock the screen....) i cannot remember what was be the thread but i really believe that there is not a concret limit for overclock....
sure that it´s not good any tipe of overclock for improve the performance...
but i have a hero overclocked at 714 mhz (factory stock at 525 mhz) since 2009 and NO PROBLEM never,,,,
and my DHD overclocked at 1200 mhz (with a quality kernel in mode smartass)
and underclocked at 245 mhz more or less and no problem....
judge by your self but use the common sense... cheeeers

At the moment i have it on smartass to 1459 max and 230 min and it seems fine. Do i just judge it on the CPU temp, and if it stays quite low (Around 30c) then im fine?

it depends buddy...
maybe its well.... the normal temp. of my batt. in use is 33-35º (but here in spain we are now at 30º !)
but my question is... are you really sure about its neccesary overclock our DHD?
I think that still DHD supports well all kinds of software with 1 GHZ of power...
maybe for a future thinks....or for gamming but always u can overclock for use a game and then return to 1ghz...
it´s only a suggestion... maybe another OP uses the processor of different mode...

The overclocking limit differs from device to device, so there is no general answer.
As a rule of thumb, when you start getting random revolts or crashes, you have gone too far.
If you want a more professional way, just slowly turn the clock of your CPU up and run a stress test after each time. It takes a bit more time but should get you pretty good results.

How long should i leave the stress test running for?
The reason i want to overclock it a little is that it just runs a bit more smoothly with it over clocked a bit. Just everything in general seems a bit better to use, its not really for gaming etc.

Qustion About Overclocking Defy

Hello Everyone
Is overclocking the defy to 1GHz is ok?and by ok i mean stable for a long time....and not for few months and then the phone is dead or something
thanx in advance
Many have been OC-ed to 1 ghz without any issue.
I'm running with 1000/52 in setvsel.
Overclocking doesn't harm unless the voltage is correct and not too much. OC to 1 GHz and see the lowest voltage that you can run stable on. Set it as the setting.
Also, CPU scales as per demand so your Defy will not run at 1 Ghz all the time, only when it requires that muscle...
And CPU's do last a long time, my 8 year old Pentium 4 just refuses to die...LOL
Running the Defy at 1000/52 and 75% with Setvsel. No problems and battery-power for full 3 days including a 6 hour geocaching trail. That's ok.
my defy can handle 1,2ghz long term, so you should be fine with 1ghz just make sure you set the vsel right, setting it too high could damage the cpu, setting it too low causes reboot, but no damage. so you can start by setting it to 50vsel, and if your phone is instable (i recommend setvsel and stability test for testing) set it a bit higher!
ok
thank you so much guys
Seriously no one knows, as no one has been owning and overclocking defy for over half year. But I think 1g is fine. Mine can easily go to 1.4g at 7x vsel, though I'm using 1.2g at 62 vsel.
mine maxed out on 1.37ghz, but im still using [email protected] theres nothing i use 800mhz cant handle, and with undervolting i can seriously lower battery consumption.
Mine is OC'd to 1ghz with Milestone overclock with no problems, and it's super fast also.

[Q] will any ROM overclock or underclock my defy ?

i dont want to under or overclock my defy...just want it as it is !!
What will happen if i install any custom rom ??
Will it O/C or U/C my defy ?? What r pros and cons of both ??
Not every custom rom, just some.
A developer usually write if the rom will under/overclock your device.
Despite this you can always choose to disable it.
CM7 will overclock and undervolt your CPU, so you should have more battery life and notice an increase in performance/general responsiveness. There's no risk in that, those values (300, 600, 1000 - I forgot at what voltages they are) are safe for daily use.
I know that MIUI e.g. bumps up your maximum clock speed to 1GHz (instead of 800MHz).
But I don't know why you don't like overclocking/undervolting, I use setvsel for some time (mainly to save battery because I have set pretty less vsel rates and when the screen is off it goes down to the lowest value) and normally you can't break your phone unless you set it to 2GHz and let it boot from start.
And when there are some settings included in a ROM you can be pretty sure that they won't be totally bad for your device.
what abt J boogie 3 liquid arc ??

Will jboogie3 liquidarc over or under clock ??
LiquidArc is based on CM7, so that is overclocked to 1GHz as well.
But if you really don't want that your ROM is overclocked you can still install it and then reduce the clockspeed to the standard 800 MHz yourself (Milestone overclock should be able to do that)

[Q] Maximum clock (cpu) speed

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.

Well said. This is very off topic but how would you overclock on windows? You have to mess about with the kernel right?
Sent from my HTC Wildfire using xda premium
Normally from the BIOS.
But you can also overclock from within windows using certain applications.
BIOS is the better option.

A lot of laptops have crippled bios's so there is no overclock options mainly due to the heat/cooling factor.
Laptops run pretty hot already.
Does your laptop have any overclock/frequency Settings?

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.

I'm running on 768 and it is fast enough. You can feel that the device gets warmer with 806 and needs a bit more battery.

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.
Once again sorry for the offtopic guys. I had to reply to this. I know I could have used a PM but I'm in a hurry.
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).

[Q] increase max cpu clock?

is it possible to overclock above 768mhz? my phone never gets warm and battery lasts 2+ days, completely stable at this speed, i want to learn how i can edit a kernel and increase the cpu voltage ever so slightly and increase max cpu clock and see whats stable, could you help me?
i think you will just start to get kernel panics if you try to go much higher .
i have another phone (lg 500) also with the same arm6 cpu that comes clocked at 600 from factory. i have the option to oc to 825 with custom kernel but it always panics at 806 and is stable at 787.
So i think if you want a faster phone go buy one

Nope.
P500 has an ARM11 MS7227 processor
Wildfire has an ARM11 MS7225 processor.
http://xi0.info/qualcomm-chips-kernel-arm-phones_7000.html
lol the chipset for the wildfire is MSM7225 but the cpu is arm6/11? on half of the sites is arm6 the other arm11..
Hi I have mine set to 710 and any higher starts getting random reboots.
But overclocking any higher than 768, your risking a chip melt or definitely shorting its life.

overclocking - my questions for understanding

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.
