[Q] low clock speed's

any reason for the 1.15ghz CPU speed and 400(ish)MHz gpu speed other than cost? or do you think they underclocked to save the battery? hoping we can over clock to t30l speeds

Deffently clocked to increase battery and reduce heat

No need to worry. developers will get this tablet to at least 1.5ghz or more. overclck tweaks for transformer prime should work on this also. all it'll need is root

Do we really need to overclock this? I mean I probably will anyways but a 1.3 Quad is pretty zippy by itself!

As the tegra 3's gpu compared to say the galaxy s3 (international) is fairly weak, I only hope we can OC the GPU by enough to make a difference. I am not that bothered to about OCing the cpu but I do care about the GPU

True, even at 1.0 ghz it'll do fine with most games..
I underclock my S2 to 1.0 ghz and i experienced no hiccups whatsoever.. and I'm still on dual core

The Tegra 3 used in the Nexus 7 is a version of the Tegra 3 chip that didn't work within guidelines at the regular speeds, but were within guidelines for a lower speed. This is done regularly in Intel/AMD CPUs as well. That's why there are different speed CPUs in the same model family. This way they can sell the high speed CPUs at a higher cost and still make money off the CPUs that can't run as fast. Eventually the process to make the chips will be so efficient that they will artificially lower the speeds to sell as the cheaper version and that's when you can overclock like crazy and not have instability (if the CPU product cycle lasts that long).

This suggests Nexus 7 probably won't OC so well. Which wouldn't surprise or disappoint me. It appears Asus dropped a lot of little features to keep cost down(which I think is a good move), and using CPU s that didn't bin well is one good way to keep cost low.

All aboiut OVERCLOCKING thread.

I wonder if we really "need" to overclock this beastly CPU of ours? Hell, even if i underclock to 1Ghz, most task if not all are done fast, really fast. Talking about games? Modern FPS games are driven by both CPU and GPU and thus doesnt require much of horsepower of the CPU. Im confuse why numbers of people here are crying "why they are not stable @ 1.8Ghz"? ... Even if you set it @ 1.8Ghz max, our phone will barely reach this clockspeed because other cores will kick-in in less than maximum speed of the primary core (if im right?) ... Is it just for Benchmark figures? Good figures doesnt equates to good performance and we all know that... Can you really sacrifice "Stability" for the sake of some "Ego-driven faaassssstttt BM"?

I swear, some people are just so dense. Why don't we all drive Honda civics? Do we really need a car with over 200hp and can top out at 150mph when most speed limits are 65mph? Why do we bother eating at expensive restaurants when we could save a ton and eat at mcdonalds? People have preferences...it's what makes the world go 'round. If people want to overclock, let them have it.

Haha good one.
I drive a v8 6.0L lumina SS, my pc is o/c'd from 2.6Ghz to 3.8Ghz Quad core, ram is overclocked to 1700mhz, have crossfired 2 5870s and tested them at 900mhz, my SIII is overclocked to 1800mhz, my LG O3D is oc @ 1350mhz (1ghz original) I guess i like fast things Maybe the OP is just a laid back happy go lucky fella and if everyone is like him we would be all driving steam powered cars and flying in propeller planes

Ok, you got me Guys .. But what pissed me is that this people all points their finger to the Kernel or Dev when they have reboots and heat-ups which is obviously the effect of their Overclocking... i can remmber a post; "damn, why i cant reach 1.8Ghz without random reboot, please fix"...

I actually agree with the op personally and I have been developing on android for four years since the g1, I don't see the need to over clock this phone as it runs really well all of the time,I too had the optimus 3d and that definitely needed overclocking as that was so painstakingly sluggish without it. the only reason I would overclock is for benchmark results other than that its just another drain on the battery for no real world performance gain

you just can't fix ignorance. if someone doesn't understand the concept and risks of overclocking, let them figure it out. sometimes it irks me to encounter posts like that as well.

Off topic: Optimus3D ROM is one of the most poorly optimize in modern Android flagships... I too had one, running it with AOSP is buttery smooth but also have some compromises...

I am sure you are missing the main idea of overclocking. First of all people normally do it to achieve better results in benchmark. But more and more are starting to do it for better performance and so. Overclocking a phone is useful for the first mainly, I doubt that anyone would overclock their phone in order to play games with better fps for instance. The whole idea is bad, there is a large difference between a phone with minimal cooling and a big ass desktop with 50 fans. If we want our devices to last longer we needn't touch them to make them "faster".

When I can overclock to 1.6gh AND under volt to 50mv below the stock voltage for 1.4GHZ it's pretty much a no-brainer

Low benchmark scores?

So i've seen in internet that people who uses trinity kernel scores over 7k (in quadrant bench) @ 1.64ghz.And im with 1.7ghz and 700mhz gpu still get arround 6696~ [Got nexus 7 32gb 3g model]...So what's the problem?How can i increase scores?And improve overall performance?
Btw is there any software or something that could fix blown speakers ?

the gpu speed doesnt matter as quadrant doesnt test gpu. it looks at our fps, and our fps will be 60fps no matter how high your gpu is oc'd. lower your gpu speed as it increases how hot the device gets. are you using the trinity kernel toolbox app btw? at 1.7ghz i get around 6900-7200. make sure that you disable tegra hotplug and enable all four cores, for that extra bonus in your scores. and that you bench at 1700/1700(high/low)(dont let the device scale). also, make sure that your device isnt getting thermally throttled. if it is, it automatically reduces your cpu speed no matter what you set it to.

Yes i use trinity kernel toolbox.I always disable tegra hotplug,using fsyn for faster all options to fastest .But still max score was 6600~...

Don't worry about the score. It doesn't matter as long as your device is running nice and smooth, right?

WARNING!! Don't overclock GPU

I am running the siah kernel on my s3 and a few minutes ago I overclocked the GPU and I almost ''burned it''. The screen started flickering when running graphic heavy tasks, had to reboot twice, and thanks god it got back to it's normal behavior. This is what happens on the SIII, but it might happen the same on other devices, too.

Overclocking is always a risk isn't it? Keep to safe or stable clocks

Overclocking will generate more heat, especially when it's running at the higher clocks you should always be careful when you overclock.

Well, when you push something to work at a higher clock speed than what was intended, do you expect magical things to happen?

you must be joking right, we know overclocking is always risky, but overclocking to 800mhz is just stupidity in its best, be specific and try moderate overclocking and not abusive one.

I never had problems overclocking the CPU, so I thought I would be a good idea to try the GPU, too. I was lucky this time, I tested it with modern combat 4 and worked as usual.

I have no problem to overclock the CPU even been in 1800, but when it comes to GPU I can not accelerate to more than 533, when I select 640 the phone becomes to lagy and I can see some artifacts.

Of course you will get artifacts if you going to oc gpu too much, because chip gets too hot, so you need to oc in small steps and see which frequency/voltages fits for your phone. Every phone is different.

The silicon is what defines what you can oc to. D
Different silicon quality that is

No, ANYTHING UNDER 65c is totally normal.
@OP, my GPU is overclocked to 700mhz, with a good undervolt, stable as a rock! Phones react differently to Overclocks. I can push my phone to 700mhz and 1.7ghz and it runs stable as hell - you maybe can't.

Considering the fact that the Mali 400 was designed to operate at a 275 target clock rate, I wouldn't be surprised if it craps out at more than twice the clock speed. Heck, the stock 440 mhz already surpasses this target clock by 50%

As someone that's been overclocking for over a decade, it slightly depresses me that overclocking today (on all systems and devices) is so easy that people that clearly have no idea what they are doing, the consequences of what they are doing or know what the solutions to the problems they encounter are able to jump right in and do it.
Everyone in this thread is talking about heat, despite the fact that the OP's, and a number of other peoples issues posted here are clearly not heat issues at all. The flickering and artifacts people are talking about is in 90% of the cases here caused by a GPU voltage that is insufficient for the current clock frequency. Your GPU won't overheat running your UI for example, nor will it have massively overheated by running a game for a few seconds. This is a voltage issue, not heat. Lower your GPU voltage at your lower clock speeds and you'll get exactly the same graphic issues, despite the fact you've made your GPU run cooler.
Also, for the record. Just because a chip is voltage limit, increasing it's voltage by X amount isn't guaranteed to fix it. Some chips will simply just not be capable of hitting a certain speed. Being voltage limited isn't an excuse to whack the voltage slider up, because that's definitely a quick way to a dead phone! If a given clock speed quickly gives you artifacts, try giving an extra 25-50mv. If there is no improvement I'd give up, as the gains start becoming impractical for the voltage levels required.

No it isn't. Arm's official website quotes upto 395MHz @ 65nm, and given that clockspeed headroom increases as process nodes decrease, getting 440+MHz at 40nm sounds exactly like what you'd expect. Given that many many many things can effect this, quoting theoretical design figures is largely useless anyway. It all comes down to what performance metrics the SoC designer is looking for, as you can easily exchange power consumption for performance and gain more clock speed.

:good::good::good::good::good: thumbs up to another person that know's what he is doing glad there are people out there that aren't N00BS I've been overclocking for 8 years so i know what i'm doing.

I clock my GPU to 640 MHz by most ,increases benchs but artifacts might appear and phone might crash,and have to reboot again by removing battery.
And by 640 MHz I mean min frequency(for a minute or two)
If max then 800 MHz works ok

Overclocking the S4 and throttling

Hi,
I have run into some results from users showing that overclocking is indeed counter productive on the s4 as it would bench lower due to throttling as a result of overheating. Has anyone else actually benefited from overclocking it? If so let's see some screeniez actually proving that it is worth to overclock and at what point the throttling begins to take effect from CPU overheating.

Ward

i had very good resoults but with overclocking gpu not cpu. Everyithing was smoother with overclocking GPU, so i recommended that you overclock GPU and you will get best resoults for daily use. Otherwise overclocking CPU is still good but dont promise any real life perfomance, i have overclocked mine for like 200Mhz along with gpu and get best possible resoult for daily usage. But i can tell you that battery is not happy about this U need powerbank in you pocket to get through day.

Compared to my stock Note 10+, my stock S4+ is so slow it's not even worth comparing.
You only have so much to work with... better architecture, faster chipsets and memory make substantial improvements in the newer platforms even with no overclocking.
At least until Android 10, then things start going to hell... scoped storage sucks.
So far Pie is the Android OS's zenith in my opinion.
