What is meaning of 1GHz Hack - HD2 General

Found some cook rom that say 1GHz Hack. What is meaning, as HD2 is using 1GHz CPU already. Thank you!

It means that the CPU is not throttling. It's always at 1ghz.
Even though it's a 1ghz (capable) processor, it'll scale depending on the programs that you're running. For instance, when the phone is at idle, it could be at 500mhz and when you run GPS program it's at 1ghz (just an example). Scaling/throttling improves battery life, so when you use your 1ghz ROM hack, expect your battery to drain much faster.

Closing this as there is a well documented thread already on this subject.

How do over clock or clock my CPU to the maximum speed?

Questions:
1) How do you know if the Omnia Pro isn't also underclocked?
2) How come no one ever said that the Xperia X1 was underclocked?
3) How come there are no tweaks/ways to overclock/clock the Xperia X1?
[p.s. i have a larger battery I can withstand the strain of power usage]
4) Are there anyways to clock my CPU? Should I change my clockspeed on the X1 since I got a superb extended 3600 battery?
no offence mate, but aren't You spamming this boards a bit recently? it was mentioned dozen times before, that for now there is no method to overclock qualcomm cpus.
I once did a pretty thorough search of the registry and couldn't find anything relating to clock speed. Otherwise, Bronx is right. There are no programs you can buy etc to overclock. Some websites mistakenly list Xperia as compatible with overclocking software, but it's a mistake.

Yeah but I needed a definite answer to this question. I copied and paste it from my original thread. Obviously no one answered my question and it pissed me off. I want my Xperia to be fast as possible as I plan on keeping my Xperia until X3 or a better phone which based on my expectations and requirements will be a very long time.
have you tried the nueDynamicClock?
it can lower the clock speed to save battery life, my X1 can last up to 3days now.. (w/minimal wi-fi use)
it also have a MaxPerformanceprofile.. i haven't tested it yet..

I'm going to try it soon.
Since I have 3600 mAh battery, I don't mind using the full potentials of my CPU.

IF you had an original thread you should just bump it btw you already told us you had a 3600 in the first post
For the Google Phones that have the same CPU like the X1 but run only with 400 MHz this is true.
So CPU Scaling/Increasing works.
Keywords for setting the cpu speed are "cpu scaling"
In Linux you need this comand here to get information about the cpu speed.
cat /sys/devices/system/cpu/cpu0/cpufreq/*
A typical output is this here
800000
1600000
800000
1600000 800000
ondemand conservative performance
800000
powernow-k8
ondemand
1600000
800000

As you can see on my Linux Laptop system i am able to run the Notebook with 800 MHz and 1600 Mhz. My Actual speed is 800 MHz and the extra boost of 1600 Mhz will be only enabled ondemand triggered by conservative usage.
We need the right cpu scaling module (see powernow-k8) in linux for setting the cpu clock in X1 the way that we like it. Thats all every other exist allready

mind you they don't just underclock cpus to save batt time also
if they don't have good enough cooling on the chip in which case
you can kill it
in which case the warrenty would be void

Then what is the point in having 528 MHz CPU?

Marketing on the basis of creating false hope for clocking the CPU later?
Most likely an issue of heat and protecting the CPU over time. From what I understand, most phone CPUs of 500Mhz and over are underclocked.
The Palm Pre and iPhone cpu is underclocked to 600Mhz[1], the iPhone's 620Mhz was underclocked to somewhere over 400Mhz, even other HTC phones using the same Qualcomm 528Mhz as in the X1 are underclocked to 400Mhz.

Right, so does anyone have any idea why people are underclocking? Why not just have a ****ing a 400 MHz CPU on the X1 and be done with it? Why waste 100-200 MHz that won't even be used? Have I gone crazy are all these companies just plain retarded?
Calm down.
If a CPU is built to withstand a maximum of 528Mhz, then underclocking it will extend the CPU life and reduce heating. If you took a 400Mhz CPU and ran it at max all the time it would have a decreased life compared to a 528Mhz underclocked to 400Mhz.

hope dies last dont it
well... that doesn't mean anything. as usual, before it gets released most of us will be on new device.
my advice: enjoy xperia as it is. soon You'll have to jump on to something more powerful, because one day all phones will be smartphones. it is a one way ticket and tg 01 is a sign of things to come. I am hoping, that microsoft marketplace will encourage coders to make some wonder apps for future winmo devices.
if the higher Hz cpus were made to run with a bigger headsink or even active cooling it would be somewhat of a problem for the phone makers so underclocking it would make sense
do they're official marketing push the high hz or did it just appear as specs on an unofficial site?
one reason one may put in a cpu which is able to run faster then it does is that the cheapest cpu is the one most mass produced not the one which give the lowest spcs
supply and demand set prices not speed and performance

As someone already said, because an underclocked CPU have an extended life and less heat compared with a CPU running always at full speed.
Take as an example laptop processors. You have 4 core but they do not always run at full speed. Why? because you have less heat, more battery life (if you have a 3600 battery, that doesn't mean everyone else have one...X1 is shipped with a 1500 battery pack), longer life.
Another answer is: because 400mhz cpu are not produced anymore or, if still in production, they cost a lot of money, compared with the mass production of new cpu. It is just economy of scale.
The real point is: can't they make a dinamic switching CPU, so that it will run 400mhz most of the time and 528mhz just when it is overloaded?

[Q] Everytime I check system information on Quadrant, it says cpu is at 800mhz

Hi guys, like I said in the title, is it because the phone is not doing heavy tasks? And will the cpu ever run at 1Ghz at all?
just being curious...
Interesting... mine's showing 400mhz (idle). afaik those chips should run @ 600mhz when idle, not 400mhz.
I presume that you can ignore that, as long as your stock firmware (unrooted/unlagfixed) gives you a result of 900(~).
ye it'll run at 1GHz if you're not using any overclocking kernal along with SetCPU. it's on a "on-demand" governer that basically uses more CPU juice as more CPU heavy tasks are carried out.

DHD CPU Frequency concerns...

Hello people,
The CPU frequency on my DHD becomes stable at around 300MHz. Y is that ? The DHD has a 1GHz processor yet it doesn't consume at least most of it for better performance. Is root the only solution to my problem ?
Is there an average CPU frequency on DHDs ?

How do you come to that conclusion/statement?
When u mean stable?
What do you mean with stable? does it freeze or reboot on anyother freq?
Yes the Desire HD has a 1Ghz cpu, but that doesnt mean it runts on 1Ghz, it means its the max it runs.. its going up and down from 248 to 1024mhz all the time, depending on stress.. if it would be at 1024mhz 24/7 the battery would end faster than you´d like it...
And yes, its possible to control this settings through rooting and setCPU
The cpu is 1ghz but it throttles back to save power all cpus Do this. If you open a monitoring application chances are it sees the throttled speed and reports that first as the upclock is delayed
Sent from my Desire HD using XDA App
As tvoben said, the processor frequency is variable depending upon the load. The CPU will only be at 1 GHz only when it needs to, e.g. games, videos etc. Most of the idle time, the CPU should be at a low frequency.
Yes its when it gets stuck at 1 ghz at 100% that u need to start to worry. HTC kindly allowed many users to exprerience the impact this has on battery life with the recent ota update.
Sent from my Desire HD using XDA App
DHD usually runs at 681.87 MHz. When needed the clock speeds jumps to 1GHz.

G2/Desire Z over-clock

How far have people got with over clocking their Visions?
Mines over clocked at 1GHz, i don't think id be increasing it any time soon think it would ruin my battery life
How far have all you all got to? Stable of course
That I know, we're at 1.8ghz so far. I keep mine at 806mhz all day since I barely use it throughout the day. Once I get home, I clock it up to 1.5ghz when I'm using it.
I've ran it once at 1.8ghz running a couple of benchmarks (linpack, neocore, quadrant)
It did very well, but, ran very hot (could be due to the fact I had it connected to the charger at the same time)
Either case, how much you get out of your battery depends on how you use it, how you set up your cpu profiles (dependant on which you use. I.e. cpu tuner, setcpu), and what frequency you're constantly letting your phone run on.
I run mine at 1.5ghz, see no need to push it further. Im getting all the performance I need at 1.5ghz. I use setcpu profiles, one to severely underclock when it reaches a certain temp and a charging profile that runs at stock clock to reduce heat when charging.
1.3ghz. Not like i feel it however. But 1.4ghz one they have posted wasnt 100% stable for me.

cpu core

I have some question about cpu cores. I searched for them in net but can't find good answer. I posted this thread in s3 neo forum because i want to about cpu cores of s3 neo plus.
what is exactly cpu cores? are they different parts of cpu or they are just different virtually?
Is running one core in 600mhz will use same amount of power used to run two core at 300 mhz?
can one core of cpu can get damaged while the other cores are working fine?
can i run different cpu in different frequency?
if i turn off all core except one will there is a chance that it will get damaged or lower its lifetime?
what i mean to say is does turning off some cores effect the whole cpu of affect some parts of cpu?
does cpu cores use different parts of cpu or every core can use whole cpu?
I am a newbie so if i have done some mistake asking those questions please forgive me because i am new in this forum and i dont know all the rules. and sorry for my bad english.
1) Cores are separate processing units built into the CPU. They are not virtual.
2) Power usage depends more on the CPU itself than the core speeds. I'm not sure about this question, but I would assume that multiple cores would consume slightly more power, but it's more than likely a negligible amount.
3) I would assume so, but I've never heard of such an occurrence. I would think that if one core dies, the whole CPU would be rendered useless.
4) If you're asking whether you can have separate cores running at different speeds, then no. There are apps that let you disable and enable cores though. You can also overclock (or downclock) core frequencies with specially designed kernels (of course you'll have to root your phone). So theoretically you could boost up a 1.4ghz quad core CPU to a 1.5ghz or more, with an appropriate hit on battery life and temperature.
5) I doubt it. But your phone will be very, very slow. And forget about multi-tasking.
6) It'll affect the whole CPU. While cores are separate parts, they are built into the central unit itself, so powering on a core powers the whole CPU.
