help me please

hi all
i have installed prime hd 9 with custom kernel i want to exactly know at what min and max CPU frequency should i keep for good high speed performance which is stable i kept some frequency at random and it was not that much speed it slowed my phone and in what governor should i keep

I personally dont recommend doing anything with your CPU because from my experience I didnt see so much difference and speeding up your CPU will make you battery drain faster and you CPU will reach highier temps. For the governor I use the performance one because it is constantly keeping the clocks on the highest set values. It makes the phone work smoother and while changing clocks its slowing the phone down. You can try and look for every governor meaning but I recommend the performance one. To monitor the temps use SetCPU`s widget.

Q - Overclock

Hy XDA,
I have a simple question:
Why does my phone turn off if i OC it too high?
Cpu can't handle it or battery overheat?

But Which?
All theese too?
Anyway i'll make a test:
I will OC higher and higher and run a Quadrant Benchmark, while holding my phone in front of a 90cm fan, without the phone's back cover
Will report the test's performance ^^

Its due to the cpu, every cpu is different, their tolerant limits for oc are different, you should oc the processor only uptill the point where it runs without any reboot.
Do not cross the safety limit, it might damage your processor.

Oh man. Accidentally pressed the thanks button again.
Volkswagen is cool and I hope to own one.

No problem, there we go there is a Big Thanks for you too

CPU running at 1134 mhz?

I got the phone 3 days ago and when i ran benchmarks (antutu and quadrant) they showed my atrix running at 1512 mhz. Now they show 1134mhz. This wiuld be easy to fix/ confirm if we had root.
The Phone also gets kinda got but i think that's normal.

Did u run the benchmarks with low battery? Do u have any sort of power management apps installed??

At first i did run with low battery but now i have full charge and no power management settings... i even fxz-ed to stock (just in case) and still the same

I have noticed mine clocking at 1512 for half the antutu test, then it clocks it self at 1134 or 1311. Phone does get a big sluggish in some games.

[Q] Best CPU settings for games in Apocalypse ROM?

Hey, all.
I am running the apocalypse ROM on my SGA.
While playing, i noticed that Jetpack Joyride lags a lot.
What will be the best CPU settings and governor for gaming?
Please let me know your opinion.
Also, I rarely over clock it beyond 844mhz, so is it a good idea to go beyond?
Thanks.
Peace out.

864 or even 883 is pretty stable for me

Maximum clock speeds vary with device..Impossible to give an exact figure or predict anything

I agree.
But I was just wondering which would be the best governor for gaming. Everyone may have different opinions.
Sent from my GT-S5830 using xda app-developers app

I have mine on 902mhz, always stable, very fast and very good for gaming, the best governor for gaming is either lagfree or performance.
Best of luck!

I've been wanting to OC that high, but I've been afraid of heat. You had any issues, notice it running hotter than normal?

But are you site you have no over heating issues?
And what is the minimum CPU frequency you set?

well if you scared of crashes, heat and battery drain you can set maximum to 864mhz, minimum to 245 mhz and set governors to performance will be very stable and faster. it depends on your device. i found my ace oc to 902mhz is not stable for me, it crashes often and very hot, drains the battery about 1% 6-7 mins.

Nexus 7 overclocked

I OC my n7 to 1.5 and 51mhz and when I play games like mc4 the CPU gets to 70 are higher is that bad or good please help me.

Yes, it is really bad
As long as you don't push it behind 80°C you should be fine. But as always with silicon, the cooler the better longivity.

It never hits 80 only 70-75 and are you sure this is bad? And what should I OC it to?

K I put it at 1.5 and 204mhz is it still bad ?

The effects of heat are cumulative. Same thing for temperature cycling on material work-effects (e.g. fracture mechanics)
That means that a lower temperature for an extremely long time can be worse than a high temperature for a short time. There is no magic "you are safe below this temperature" assurance that can be handed out.
If you use your device hard, you will wear it out sooner - on average. (What an individual device will experience can not be predicted in advance.)

So what is the best Overclock settings for the motley kernel and what is the safe zone for my CPU while gaming or browsing or YouTube?

Try it and find out.
What is this?? Read the kernel thread. Why would you install a kernel without knowing anything about it?

I read everything about it.... I just need some good oc settings so it won't hit 70 while gaming or is it normal to get that high while playing intensive games?

There is nothing magical about 70C.
For long-duration loads (say gaming for several hours straight), the CPU temperature rise will be a certain temperature rise above ambient for that load condition - so somebody gaming outdoors in the tropics will experience a higher CPU temp than someone indoors in air conditioning.
My tablet (stock rooted) idles at about 38-40C with the screen on in a room at 20C (68F). Call that a 20C rise above ambient for an "idle, screen-on" condition.
I have coded a threaded native program meant to saturate each CPU core as well as the memory bus (& tweaked it for max temperature rise); when running it simultaneously with a long-lived graphics benchmark, I have seen peak cpu temps of 85C. This corresponds to a 65C rise over ambient. This is a ridiculous load, though.
As mentioned elsewhere, the stock kernel has thermal protection mechanisms: a rate throttle at 95C and an emergency shutdown at 100C. With that (above) ridiculous load, I couldn't get there with 4 cores @ 1.2 GHz. It is possible that by running the same load for many hours continuously (or inside a hot car) it might hit that limit though.
But I don't think that the existence of an emergency shut-off means that below that temperature means "your device won't experience long-term degradation" - more likely that emergency shutdown is there to prevent somebody's defective tablet from burning down a house. Asus/Google are much more concerned about tort lawyers and product liability lawsuits than they are about the longevity of somebody's stupid $200 tablet... that has an invalidated warranty.
If you are gaming for an hour or so at a time, 70 or 75C is probably not going to cause an immediate hardware failure.
Your tablet is made out of a bunch of materials that are subject to a variety of failure mechanisms. Every one of those mechanisms proceed at a faster rate at higher temperatures. (Remember the old rule of thumb "reaction rates double for every 10C rise in temperature"?)
So, enjoy your tablet for gaming. But don't leave the performance governor enabled all the time: your device will spend more time over the course of its life in an idle condition than actually doing anything for you - there is no point in you cooking it slowly to death while it does nothing useful for you.
cheers

You're right but I get 70c in a matter of minutes I think I'm just gonna retire from oc and stick with the stock kernel

Okay so just keep it at 1.2?

it is better it in1.3 and min 200 (for battery saving) but 1.2 is well, why dont overclock gpu a bit, or use some tweaks or a new kernel

You can do it with M-kernel and trickster mod

What do I oc the GPU too?

I can't stress enough the importance of voltages to temps. On stock Trinity kernel I ran 1.6ghz at "default" voltages (can't remember how much, something like 1.2v) and hit temps of 95c.
I dropped it down to 1.125v and my temps went down to a max of 75c and usually much cooler.
Anyways, you'd be surprised just how much the voltage affects the temps.
Good luck guys!
