[Q] Question about overclocking safe limits - Desire HD Q&A, Help & Troubleshooting

Hi there!
My phone is desire hd(arhd 5.1.11), right now I am thinking to set it on 1450(buzz oc+ kernel) with 1225mV vdd. As we all know that will lead to much more heat, and while my phone has battery temp sensor, it lacks processor one. For 24/7 is it appropriate to set it on that freq/voltage? I am sure there are people with far more experience than me on overclocking that phone, and I will be thankful if they want to share they opinions/exp .
Cheers!

Yes, it is safe because your phone doesn't run on 1.5ghz the whole day. If the min frequrncy is set to a lower value than 1.5ghz your phone will UC itself down to that value.
Furthermore, the HTC Flyer has the same cpu as our DHD and it runs at 1.5ghz on stock.

True, I just worried because of flyer more space to cool down the cpu. Tho, I read that Qualcomm deliver MSM8255 Snapdragon on 1.4GHz frequency, then the buyer decide what freq to set. Now I am on 1.46GHz(1225mV), I think it's the sweet spot, because for 1.5-1.55 voltage goes like hell up . Thanks for your answer.

Regard overclocking to 1.8 ghz

Hi, im just about to flash leedroids 2.2.3 rom, which can oc to 1.8 ghz with setcpu, just wondering if there are any dangers in having it at this speed? anything to be aware of ?
It might fry your device, it might not, you never know. There's no need to run it at 1,8ghz. I'd recommend max 1,2ghz for daily use though everything runs smoot at 1ghz already.
If you overclock to 1.8Ghz you will increase the risks to fry your CPU(and hence, your device will be destroyed). Lol.
Also overclocking too high can drain your battery real fast. As per Hawks556, max 1.2Ghz would be fine.(perhaps it is almost to optimal)
I overclock mine at 1.16Ghz and it is already very smooth in LeeDrOid.
You may sometimes wish to overclock it until 1.8GHz is just to show off to your peers only. Maybe through quadrants. But later on make sure you underclock it back.
Cheers. =)
thanks for the help, lol whole thing just froze while i was reading it better underclock it lol : /
OC up to 1.5ghz should not harm your device.
Take a look at ths HTC Flyer: it has the same CPU as the DHD but it's set to 1.5ghz by default.
So there is no risk in overclocking up to 1.5ghz in my opinion.

[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.

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.

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.

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.

[Q] Phone stucks at 768 clock speed

I got a little problem:
I can overclock my wildfire to only 710 Mhz if i overclock it to 768 the phone stucks and i can't do anything.
At the moment I'm using Cyanogenmod 9 but i think it isn't because of the ROM 'cause in Rempuzzle ROM i had this bug too.
Should i flash another Kernel or what should i do?
As far as I know, it's a hardware limitation.
It depends on the processor, some processors have high tolerance to overclocking, some don't.
In another words, some processors can handle high speeds. The defualt speed is actually 512-ish so when you increase to 768, it just can't handle the speed so the phone freezes/reboots.
Some wildfires can handle those speeds, luckily mine does
That doesn't mean you have bad or faulty hardware. The processor just can't handle it
Correct me if I'm wrong .

I think from my new experience it might be a bit of a combo between the actual chip and the kernel settings, on my s2 with 1 kernel I can only oc to 1300 with both cores on but with another (my favorite one anyway) I can hit 1500 both cores on.
I still think the actual processor has more input than the kernel though, and all the extra strain from not having a gpu can't help either.
EDIT: I'm not saying flashing a new kernel will help you reach 768 though , the lack of resources elsewhere is a huge hinderence to the wildfire.

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.

http://forum.xda-developers.com/showthread.php?t=1647993
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.

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?
