It's safe to run Tab at 1.2GHz?

Hi guys. I looking forward to ROM with can work at 1.2GHz. I think most of XDA users have modified ROM working at 1.2GHz, so everything fine? It's save to run Galxy Tab at 1.2GHz?

1.2 has been stable for me for well over a month now. I run 1.4 from time to time when I want to play games or just show off. Some tabs report overheating, but use setCPU profiles to alert you if that happens and you wont run into any problems. I have setCPU to warn me at 40 degrees and at 41 it goes down to 800mhz. Just keep your eyes on the temperature to be safe.

Its a popular misconception that the tab runs at overclock frequency ALL THE time. Unless the kernel (which I seriously doubt coz that would be stupid) is programmed to run at maximum clock frequency or you have set it up yourself (with setCPU or voltage control or w/e overclocking utility you use) which is basically an explosion waiting to happen (or at least crash). The tab runs at a RANGE of frequencies it runs at max frequency (1.2 or 1.4) on demand like playing a game or an HD movie or anything stressful.

You want to say, like PC CPU, that Tab ARM Cortex A8 chip working on range of frequencies? It's possible because of battery save, but I think Tab's Cortex A8 is designed to work at 1GHz all the time without any problems.

DarkPal is right.
While you're theoretically correct too, in the sense that the Tab's Hummingbird is designed to be able to work at 1Ghz all the time, by why would you want to do that? It'll kill your battery if you set it to run at 1Ghz all the time, much less at the higher frequencies that these CPU were not rated to run. Not to mention the heat issues.
There's a reason these ARM-based chips scale up and down the frequency scale according to the CPU governors' settings and load demand, and that's why ARM-based chips are known for their battery savings.

galaxy tab 4G Lte runs at 1.2Ghz

I've been running mine at 1.4 for about a month now but undervolted too. Perfectly stable. If you are using SetCPU app you'll be able to see how much time your tab spends at each level.

Bit of a noob question but apart from games in what other areas does overclocking help?

I notice the difference with video. Crisper and smoother. It's not a big thing, but why not do it if you can?

Because it does run your battery faster and hotter, as well as the processor itself...
Force a sprinter to run 5 miles, they can do it, but I bet they tear something along the way...

Oh yeah, thanks to the illustrious Rotohammer that's not a problem...
Ever since I upgraded to Roto's JMI ROM and a few other tweaks [ see my post: http://forum.xda-developers.com/showthread.php?p=12786456*** Galaxy Tab Master Tweak Thread*** ] the battery life on the galaxy tab has been absolutely insane. Even though the phone is overclocked to 1.4 Mhz.
I used to come home at the end of the day (before overclocking) and my battery would be approximately 15 percent, now it's always over 50 percent. I don't know what the black magic is, but it is good...

Heavy games problem

Hello guys my problem today is heavy games like mass effects and asphalt 6
Problem is my phone runs those games slowly very slowly and I think it should be faster than this but why heavy games are slowly if we compare it with iPhone 4 (has same processor speed)iPhone runs them very fast so should I do something to run them vary fastwithout hangs thnx

Try closing some background apps. Performance also depends on what android version you run (but I don't think you use Froyo, gingerbread is way better )

GPU in Black is not first class. Actually it's rather old and even if CPU speed is the same than in Apple then GPU is much way weaker.

Can I use chainfire???!!!!

chainfire will make only things worse - it will emulate another GPU...
Sorry I mislead you - GPU in IPhone4 is comparable with that in Black - IPhone4S
just crashes Black's...
I don't have those games so I can't check how it run at my config. But Real Racing 2 runs fine on Black.

thats wierd cause, if my mind doesn't trick me, I remember when first using my OB for first time, a year ago or something, it had froyo and asphalt6HD and I spend hours playing it without problem before I even know about this forum...
now with the big wave of new roms, you can play almost anything you want

that is absolutely not true!!!!....the GPU of black is still on par with most mid range droids rolling over adreno 200/205.
and of the Iphone, i feel u r comparing OB with iPhone 4 and not 4S, since they are on par. iPhone 4's GPU is as much powerful as OB's. the optimization is of the light (read "flash" free )OS
my OB plays most games seriously well... i feel it's a seriously well balanced device for the price range.
@hemo ali: try and use a task manager before your game start to clear off and release RAM. and avoid intensive apps like browsing, streaming etc while playing.
or better yet, get zeus/marvel

thnx for advice I hope to use zeus or marvel but my problem is in rtl support
is Zeus or Marvel supports rtl???
also what about graphics can I use chainfire without getting worse graphics??

okay another big problem after installing chainfire drivers And i noticed it goes well
but now another big problem(priority is very high)phone full hangs and stopped 4time/1day And I should release battery then put it again why is it related with chinfire???!!

I use cm7.2 rc3 with heux 4.0 kernerl, with chain fire 3d with smartass2 governer.
I play asphalt6, st iv and ShadowGun.
I dont find any perofrmance issues.
The games some time lag, and I see in CPU spy the CPU is stuck at 300 Mhz, killing the game and relaunching it fixes it. I see in CPU spy that CPU is scalled at 1 Ghz

I use Zeus 6.28n and i play both games + front line commando.. and i have no lag and works fine. i didn't change any frequency.. i use RARELY the memory booster when i switch from game to game..

[Q] Laggy games?processor running at 1000mhz max?

i m on v10D, i just rooted and intalled setcpu, 1500 max 1400 min gov: performance, now just after i restart/turn on my device, the frequency is right..but then after a couple of minutes it drops to 1000 mhz..i have 2 questions:1.is there a way to fix this,2.does any other version( other than v10D )offer better gaming experience...and if so, which is the best?
Thanks for your time :good:

Well i have mine when I game set to 1500 low and high plus performance. It never drops and other then that. One issue I did encounter is that as long u have profiles set up and checked it will still use them regardless if u set it in the front page to a certain speed. So u need to uncheck all profiles and also uncheck the use profiles. Basically uncheck it all then even if u uncheck use profile it still will use the profile if u select one. Here a picture from what I mean. See how I unchecked everything. U need to do this to or it still will the profiles even if not checked the use profile box.

btw, are you facing any lags, framedrops, etc on v10F?
and is there any way to force the 4 cores to work simultaneously?

I have the same problem. When i set frequencies to 1500 min and max in game it's still change to lower.

My problem is same as you. I don't rooted my phone.
I have stock v10h firmware hungarian,
When I play games, all games very laggy.
I checked the CPU speeds, the max frequency is 1300Mhz and below.
What is this ? Tegra 3 stupidity ?

Just write 3845#*880# and on the bottom you can see cpu usage, turn it on and play some game.

that 's 3 people with the same problem...and no one is helping -.-, ^^^and he 's on v10H so its not fixed by update .-.
anyone??

It didn't change anything for me to put the CPU @ 1,5GHz constantly. I did a test with the game Horn and its lagging exactly as with the default CPU governor enabled.
If you think about it for a moment, it makes sense, as the GPU is doing the majority of work.

Tegra 3 CPU Clocks
Based on what I understand about Tegra 3 from this thread- http://forum.xda-developers.com/showthread.php?t=1664391, the CPU has 3 different "modes". 1.5Ghz single core, 1.4Ghz dual and triple core, and 1.2Ghz quad core (At a certain temperature, remains on 1.4Ghz or 1.3Ghz until that temperature is reached... quickly). The reason why the frequencies go down is because when the phone is utilising more cores, the frequency drops too. The move from 1.5Ghz to 1.4Ghz causes lag in games at times, which is why the maximum should be set to 1.4Ghz to prevent this from occuring. Also they said that the performance governor causes 2 of the 4 cores to no longer be in use, which is NOT good for Tegra games such as ShadowGun as all 4 cores cannot be used, so they advised people only to use it for Non-Tegra games as they do not use all the cores. Hoped I helped in any way, even though I'm a new guy. I'm not sure if this applies for ALL Tegra 3 devices or just the HTC One X, but it still looks like useful information.

Thanks for your reply..but for me, the frequency doesnt drop to any of the values above, it automatically drops to1000 and mostly its on 1 core
Which brings me to another problem...i need a way to force the activation of the 4 cores simultaneously...in most games the cpu is stuck at 100% single or dual core

Most games are not optimised to use 4 cores, so I guess using only 1 or 2 cores should be normal. What governor are you using for games, because this might have an effect on the performance.

I tried all governors..performance isnt the best, idk why..userspace seems to work fine, but still when i set min and max freq above 1000mhz, it automatically drops to 1000mhz ._. and that isnt quite good for gaming, and since i bought this device over s3 for gaming, i feel f*cked
so would an update to v10F or a hard reset fix anything??
EDIT: and there 's 4 other people with the same problem and one of them has v10F so hardware problem??if so, im hanging myself

[Q] Only one core used in gaming, why?

Since i noticed lags in games i tried to figure out whats wrong with my phone, and finally found app named Quick System Info PRO (its free) and there is an option "live monitor" which shows cpu freq and usage per every core in on screen widget, which is staint over most content on screen including games. I've played some titles like GTA3, NFS most wanted, shadowgun etc. and every single game uses ony one core scaling usualy between 1000-1500 MHz with approx. 70-100% usage. I've tried same thing on my nexus 7 (android 4.2.2) and everything runs very fast and it uses 2-3 cores scaled around 600-1000 MHz with 20-40% usage.
There is no problem in chrome, antutu they're using more cores, this happens only in games (every title I've played have the same issue even THD titles)
so whats the matter? is it ICS fault? Do you have the same issue? is there any way to fix it or will JB updade fix it?
I'm using stock LG-P880-V10h-NOV-19-2012 firmware, phone is rooted.

I've noticed exactly the same thing as you, I've checked with the "hidden code" to check for core speeds

really strange i wish someone to fix this bug is really disappointed quad core 1gb ram tegra 3 and lag all games
+ tegra games.... lets think possitive...

Is there any way to fix it? hope JB will solve everything

Something I saw in the one x forum which I will try when I get home is limiting the max frequency to 1ghz, as it won't use all 4 cores any higher than this because of overheat. More likely the cause is bad optimization

Yes, what you say is somewhat true. When the core of the phone hits 40 degrees celsius, it clocks at a lower speed and that's when you see the "slow charging" even though you plug it in a wall socket.

What I read was 1500mhz: 1 core, 1100-1400: 2 to 3 cores and >1000mhz: 4 cores. I know of the temperature setting also. Tested this with NFS MW, I noticed no improvements but neither did it perform any worse which is interesting for a game that's not the smoothest

Just like normal computers, if a piece of software is not designed to use multi threading.. then it will only use one cpu.

Yep its mostly devs fault, however they should be using it anyway because they are compatible with galaxy s3? Could it be possible to hack it so it uses the s3 configuration and achieve multiple for usage, or is it impossible across different chipsets? I don't get it, I've seen that most games we complain about do not have these issues on the HTC one x
Sent from my LG-P880

You can modify build.prop to look like that of a galaxy s3 (edit model, manufacturer etc..), might trigger it, but that might create problems with other apps (including play store)
I think it's just bad programming since there are functions in android java that will allow you to get the number of cores, so then.. you can enable multi threading... not sure why they would use device detection or whatever.. I mean if a device got 4 cpus, it got 4 cpus! doesnt have to be a bloody s3

I think it's ICS 4.0.3 fault, like I said before everything runs smooth on Nexus 7 which have 4.2.2 and notice that one X already have 4.1.2.
Suprising fact I've found on polish wikipedia is improvements list of 4.1.2 and line that says:
"optymalizacja wydajności w grach dla procesorów NVidia Tegra 3 i kart graficznych NVidia GeForce ULP"
which means: "In-game performance optimalisation for NVidia Tegra 3 proccessors and NVidia GeForce ULP graphics cards"
Hope thats true

Well like you say they run fine on other hardware, HD games must have multi threading support for these and the galaxy s3, so the question is why aren't they using it for ours? Must be the software, even forcing all cores online does nothing to help.

If it uses handset detection, and detects HOX and it ticks it as supported, then its going to work because it will activate multithreading.. but probably it doesnt detect the lg 4x as supported... because IMO, it uses the wrong detection (device based) to determine mutithreading.

Its not exactly our phones fault that most games using 1 core, in-fact almost all apps runs using 1 core they are not yet optimized to use multi-core,in our case its little developers fault and little ICS fault.
Also I am still confused why you people complain about lags? This device is very smooth and I play HD games on my (50 inch full HD) TV with my PS3 bluetooth controller(specially bought for gaming on 4X) and it runs just fine. I play Shadow Gun deadzone online with no lags(even with tiny lag - single frame skip means I am dead)...etc NFS MW runs fine too rarely it runs little slow in first few seconds of race but later it becomes fine.
I had issues with heat and battery drain problem to overcome this I have underclock my device to 4cores 1.2ghz (Governor - onthedemand) and even after underclocking it runs all my games fine. I have read (never tested) for gaming governor - Performance is i deal but battery drains faster.
However similar complains were there in HTC OneX as well until it gets updated to JB.
So I assume this issue should get resolved with JB update.

I want to know that how can I find that my cpu & gpu processors are working well ?
you know in some games I have few problems , few delays and I'm confused.
for example for "Subway Surf" I think there must be no delay or lag !
And the other question , what's your suggestion for an excellent Task Manager ?
I have tried some and now I have GO on my phone but I'm so willing to know the better one !

I sometimes got lagg on subway surf
And it only happens on stock rom tho

Everything is probably ok. Our phone isn`t very good for games (stock) and JB became for slow for some.
Look for Gaming threads but, I can tell you this:
Root
Install Tegra Overclock (not tegrak) and set GPU Clock to 380 (more stable for me) or 416 for 3D and 2D. In Core Count, tick Force selected number of CPUs Online ONLY WHEN YOU WANT TO PLAY.
Maybe play with the thermal throttle.
Look for other kernels that support higher GPU clock. (don`t really recommend).
This is me, don`t know other users opinion:
Install Autokiller Memory Optmizer and set it to Extreme. This will consume more battery (my testing) but eliminates system UI lag.
This should do it.
Oh, of course, your Antutu Benchmark should result around 13k, but dont worry if you get 12k, it varies quite a bit.

I used LG boost app from development thread every time I wanna play
