So I've been playing with some kernels and have been deciding between stock and checkm8. One thing that I noticed tho is that you can force all cores at 2.3ghz, but after about 50% load it automatically drops to 2ghz. And at 100% cpu load it drops again at 1.5ghz. is there anyway to stop this so it runs at 2.3 even at 100% load until a certain temp?
I noticed this on both stock and checkm8
What game are you trying to run that would need all cores at 100% so it doesn't lag?

Benches and such... Like I just don't want the cpu and gpu to throttle to a lower frequency just because of high load. I only want that to happen because of temps.

gentlemen,
I awakened from my sleep, because my phone has rung indicating that the temperature is high, you turn it off and remove the battery.
should know that the problem? someone else has happened?
regards
Was that a stock feature or a rom feature?

The overheat notice is built in. If you're overclocking, you may need to step it down a notch! Also, you might want to use something like watchdog to make sure you don't have an app hogging CPU while idle, because even overclocked, it shouldn't be using so much CPU while idle to trigger the overheat warning.
I've actually decided NOT to overclock because of that... I thought my phone was immune to overheat, as it benched /stress tested fine.. then I handed it to my girlfriend and she played Princess Punt for an hour, and ignored the overheat warnings till it crashed! Ooops.

I've never done an OC to my mobile.
the ROM installed is Weapon G2x 3.0_R1
i have the Antutu Cpu Master and i have it siad to bring the cpu speed down while chargeing and also if it get over 106 it bring the speed to 600MHZ

'll try With That, since the mobile was heated, when it was connected to the charger.
the cpu speed down while chargeing (As set? )
i use setcpu and a profile that underclocks my phone when the screen is off. i use the last cm7 nightly with newest trinity kernel, which gives me more control with the cpu clock
That only happened to me on super hot days while charging in my car.

Hi.
I a speed freak! If there is something I hate, is lag.
I therefore thought of using a better kernel for my G2x.
As I understand, some kernels can OC the cpu. Wow. That's cool, first of all.
Second - any conclusions about this? Is it safe? Does it really make a difference (i don't game on my G2x)?
THANKS!
Since you obviously don't know how to use the search function, I'll just tell you that it is perfectly safe to install a kernel and constantly run it at 1.5 Gh.
Go buy setcpu from the market to set your processor speed at Max, and leave it there. All the time. No matter what.

Haha, good answer..Or you can go and download CPU master for free. =)... But honestly overclocking is not good
There's no real speed difference when overclocking install a custom kernel but don't overclocking it its a waste of battery
Sent from my LG-P999 using XDA App
risks? yes. it kills your battery faster, and battery life will drop. by battery life, i mean the amount of recharge/discharge cycles it normally will allow will drop.
pros? makes your phone much faster. and no its not a placebo. if you bump up your kernel from 1ghz to 1.5ghz, thats obviously a speed increase. how can it not be faster.
Sent from my LG-P999 using xda premium
But also the risk at a constant 1.5 of overheating and burn out of the processor.
if you're a noob and don't know exactly what OC is, don't do that.
it can kill your battery and processor much faster, make you're phone unstable and accidentally overheat and burn out your processor, if you have a constant OC
processor life is worth the wait imo
I oc mine tops 1.2 and its as fast as it needs to be for my needs. I also bump up the minimal speed to about 500-800 cuz our g2x's should never be running that slow even when idle/screen off imo.

I set my cpu to run at minimum when the temp reaches a certain level. It's never actually happened though...my phone runs real cool at 1.4ghz
Sent from my LG-P999 using xda premium
I know that if you OC/UV incorrectly, it can cause stability issues. But I was wondering does it cause any damage to the phones hardware like battery, etc? And like how can you tell when SETCPU is causing problems?
Sent from my LG-P999 using xda premium
Well if you OC to high numbers your just stressing the cpu more.Knowing when you have issues is simple getting random reboots,phone getting too hot etcc.
It differs for every phone but undervolting -25 for each voltages works well.
Personally I really don't see the point overclocking to high levels like 1.4 ghz etc,Is up to individual I guess.

Yeah I have been wondering what's the point of OC to 1.4? Does it make that big of a difference in the 4g speed? And cpu speed?
Sent from my LG-P999 using xda premium
Honestly, there really is no point other than for benchmarks. I, like mt3g, actually underclock the phone to something like 750-760mhz; it runs beautifully smooth.
Other than that, if you game a lot and want to maximize FPS, then overclocking would do that for you.
Doesn't have anything to do with 4g speed afaik. That's entirely reception.
Yeah 4g is about reception and tmobile simply.
I mean I had single core devices like MT4g ,SGS 4g for the most part on a day to day basis transitions to transitions theres not much diffirence in terms of speed. Now for FPS and a few other games you need that dual core.Point is there"s no need to OC a dual core phone!

I have had mine OC'd to 1.1 ghz with some undervolts. It is very stable , 10-12 hr battery with medium to heavy use , and ofcourse fast. Took a while to find the best settings.
When I have SetCPU set to 1015 megahertz, that's the same as stock voltage, isn't it?

Changes you might see are battery life but not that much unless you so how mess with voltage. Like other have said you know it effecting stability when its overheating, shutting down randomly, exiting program randomly.
Hi guys!
I have now confirmed through the cpuz app and antutu , that the power saving mode only uses a7 cores (not more than 1200mhz) and leaves the a15 unused no matter what the CPU requirement is.
This experiment was done in the latest MEA firmware for i9500.
I have also figured out that there is some CPU throttling going on with the latest firmware when the temp reaches 50, the a15 cores were not used in the antutu benchmark. This is also why I got an extremely low score of 22000 and then got 17000 in the second test as the CPU was heated. As soon as the CPU cooled down to 40, the cpuz app again showed all cores reaching 1600mhz when running the test in background.
These are my own findings and I apologize if this is known to everyone because I certainly didn't know that.

not just in powersave mode. I have the same results with power save off
Does this mean essentially only the A7 cores are ever used?

Try running the antutu app test in background and start the cpuz app. Look for change in the CPU clock. Are you sure it doesn't show anything more than 1200mhz?

No.
A7 is used dominantly because many conventional software tasks do not need the muscle of the A15.
There are other issues as well... just give the ROMs time to improve.
Sent from my GT-I9500
there are no such throttles at 50 C, but the boost mode is disabled by default it seems i can see antutu topping at 1.4 ghz not more than that..
I got 26764 in antutu using power saving mode. The highest freq used when running antutu is 1400 (check using cpu spy).
After checking whatsapp and xda app, I check freq 1600 is also used. So it is not limited to A7 in power saving mode.
Note: I use perseus 2.1 and MEA.

Can you please tell us more about the boost mode?
Sent from my GT-I9500 using xda premium
it does show more that 1200mhz for a second or two on the first test . The cpu gets instantly throttled though (as the temp rises).
Then subsequent tests show 1200 or less.
To answer my own question, yes this does meant essentially only the A7 cores get used. Because any sort of load on the A15 causes a temp rise, which causes an auto throttle down to the A7.
Even if you fix the minimum cpu speed to be > 1200, the rom disregards youw minimum and drops lower. E. g. I fixed the minimum to 1300, ran antutu (The results were significantly better than the stock cpu settings) however near the end of the test the cpu was auto clocked down to 1000 and stayed there on any subsequent antutu tests.

samsung uses boost mode to increase throttle temp limit from 90 c to 100c in order to stay longer at higher clocks for better bench scores, when the boost mode is disabled the clock speeds will start reducing by 200mhz steps when the temp touches 90c.
Bala Gamer you know any program can log the temp while playing or bench?

Specifically something that doesn't run all CPU cores at max speed. If in recovery too long, that could lead to hardware damage.
Sent from my Nexus 5 using XDA Premium 4 mobile app
I've never heard if any troubles with phones using full speed during recovery. In that case you shouldn't play heavy games (or even simple games), watch movies, stream video and so on. Don't worry about this, the weak parts of a phone are battery, screen, buttons, orts, not the use of a recovery. This is cosmetic without any proven effect, like UV for preserving battery and so on. Even using it ten minutes every day won't cause any damage.

Not really. CPUs are built to be able to withstand this. Damage comes from excess heat and higher clock. I.e over volt.
Alright, thanks everyone.

Just in case anyone doesn't know this, CPU load / utilisation and CPU clock speed are not synonymous. A CPU can be clocking at 2 GHz or whatever but only be under 5% load. Sure, governors will usually ramp the CPU clock up under high loads. But if you think about the performance governor in Android for example, it sets the CPU at max frequency all the time, but the load will not always be 100% in fact it will hardly ever be 100%
Also if you look at a laptop, it will be clocking high, most of the time maybe not always max, but often not far off
Most android governors will get you to max clock long before 100% some even at 50%
