[Q] how much can you overclock the cpu? - Galaxy Tab S Q&A, Help & Troubleshooting

I noticed that I can only overclock the CPU from 1.9 GHZ to 2.1 GHZ with skyhigh kernel. Is there anyway to get it higher?

Not with my kernels.
99% of devices won't be stable above that and in any case will not provide any great benefit.
I did have GPU higher but is really a waste and with CPU, due to higher temps invoking thermal throttle, leading to decrease in overall benchmark/performance.
Through my extensive testing, having anything higher than my current max CPU and GPU frequency = PLACEBO
Edit: Maybe things might change compiling with Lollipop source (once released), but unlikely. Obviously I will test though

ok thank you. What about the GPU, any benefits for overclocking it?

Maybe when opening the case and adding some cooling mod to CPU/GPU, the overclocking will do better.

CPU Governor

The galaxy has a big jump from 400Mhz to 800Mhz. Is it possible by modifying the kernel to an intermediate step (600Mhz) or is the hardware limitation?
Thanks in advance

I think you should read the title... I mean the governor of the cpu. It has various speeds to save energy...
Yes. I beleive SetCPU can do this. I haven't tested though.
I think its possible, I've just added one scaling from 100,200,400,800,1000,1200
SetCPU can do that

Only with a stock kernel? So why I can only choose 100-200-400-800-1000 speeds? The ideal would be that it can be set to 600MHz, plenty of power for everyday use
You would have to change the cpu multiplier in order to get a frequency in that range.
You can't change it without adding 600 MHz in the source. SetCPU can only choose the speeds given to it by the source code. I wouldn't be too worried about it though. It only speeds up for as long as it needs to complete a task then it's usually back down to 100 MHz.

That is the question. The more intensive use it is when I use the web browser. And would have the necessary fluidity 600Mhz spending less to have it running a while to 800Mhz.
Anyway I see that the overclock is the same as a PC, with the difference of having to modify the kernel. Time will tell if any of those that modify the kernel have the same need and put it.
PD. Google Translate rules...I'm spaniard...

Hello !
A good CPU governor is design to get most CPU performance and save energy without altering too much reactivity (=introducing latency)
This is why the governor jump "as quick as possible" to high frequencies.
BTW, the quickest the CPU calculates the operation asked, the sooner it can go back to deep sleeping states.
Setting a maximum cpu frequency other than 1GHz (800MHz, 600...) is counter productive.
You'll loose both speed and autonomy because the CPU won't be so often in deepest power saving states.
(you'll find many studies about this )

[Q] increase max cpu clock?

is it possible to overclock above 768mhz? my phone never gets warm and battery lasts 2+ days, completely stable at this speed, i want to learn how i can edit a kernel and increase the cpu voltage ever so slightly and increase max cpu clock and see whats stable, could you help me?
i think you will just start to get kernel panics if you try to go much higher .
i have another phone (lg 500) also with the same arm6 cpu that comes clocked at 600 from factory. i have the option to oc to 825 with custom kernel but it always panics at 806 and is stable at 787.
So i think if you want a faster phone go buy one

Nope.
P500 has an ARM11 MS7227 processor
Wildfire has an ARM11 MS7225 processor.
http://xi0.info/qualcomm-chips-kernel-arm-phones_7000.html
lol the chipset for the wildfire is MSM7225 but the cpu is arm6/11? on half of the sites is arm6 the other arm11..
Hi I have mine set to 710 and any higher starts getting random reboots.
But overclocking any higher than 768, your risking a chip melt or definitely shorting its life.

how does the OC work? i mean then running all our core it is limited to 1.2 ghz and is 1.5 on a single core.
does that men all cores run at the OC value or just the single core?

I suggest you flash faux's kernel.
It can oc to 1.6GHZ for most user~
and it support s2W!
I expect many users will be aware of this information, but just in case you aren't.
Anyone overclocking should be aware that this will usually lead to higher power consumption which leads to more heat produced and lower battery life.
Especially if it is necessary to overvolt to acheive higher clock frequencies with stability.
Power consumption is proportional to Voltage squared, so small increases in core coltage can result in larger increases in power consumption than mught be thought.
Needless to say this can have negative impacts on battery discharge time and overall life (due to higher temperatures).
Plus there may be some throttling back of frequency if high temperatures are reached. Also possible that frequency may be reduced to 1Ghz maximum when battery voltage is low (i.e when discharged)
Hope this is helpful (first post here)

CPU throttle starts at 85c with thermal TJ-max of 99c.
also there is many debates about this, higher speed need more power which drains battery, but that said it means work gets faster meaning it can idle faster saving power, same the other side slower speeds save power but take longer to get work done using more power.

Go to Faux123 and read the opening post

it will teach you about Tegra 3 variants.
Flash Faux123 latest kernel to know what variant you have.
You can have 1.5ghz quadcore minimum, except if you have the poor variant0 of the Tegra 3, and 1.6ghz quadcore max if you have variant 3
So the overclocking you can achieve depends on your Tegra 3 variant, whatever the kernel, don't trust the figures in kernel threads titles, they just give the max if you have variant 3. And the majority of people have variant 1 so limited to 1.5ghz quadcore and there's nothing to do about it, no future kernel can change the way your CPU was manufactured.
Just, SetCPU can display 1.6ghz or more, but if you have variant 0 or 1 it will never use it (CPUspy will say 1550 and 1600 are unused frequencies)
Variant 1 can go upt to 1550mhz but not for quadcore, so who cares....! Same for kernels claiming up to 1.7ghz, it's in single/dual core, so once more, who cares?
What is important is what max speed you can achieve in quadcore, nothing else, and the limits are clearly defined by your Tegra3 variant
"all chips are not created equal" was a silly bull**** invented more than one year ago as an easy answer to noobs claiming they couldn't overclock their dual core at their max. Now, on the One-X and because of Nvidia unstable quality"all chips are not created equal" is sadly the truth.
PS: wrong=> to say that overclocking means more voltage, undervolting a custom kernel a little can surprisingly reduce heat when you push your CPU to its max,I can have both 1500mhz quadcore and less voltage than stock, as well as less heat (I was surprised, really, on the Sensation I had always found undervolting kinda useless)
PPS: true=> thermal throttle will always come pretty soon and reduce your max speed......

Your argument makes sense, but unless the governor is very efficient at controlling the CPU speed very quickly, in most cases your argument doesn’t hold true. For example when playing a game or running a CPU intensive application (where overclocking has any use) the processor works at full speed for the duration of the application.
EDIT: Frankly I don’t see any point in overclocking a phone like One X. I don’t play many games, but the few games I have played ran very smoothly. And if people are overclocking because of the (barely noticeable) laggy UI then overclocking is not a real fix anyway. Installing a custom ROM (perhaps JB), a different launcher, tweaking background apps/services are some of the more sensible and effective things to do instead.
No disrespect to the devs who are working on overclocking, but IMO HTC and nVidia must have spent a considerable amount of time and effort designing the CPU and deciding the optimal operational parameters to maximize performance while minimizing battery drain. Therefore anything out of those parameters (in theory at least) should impact either stability, or battery life. Perhaps the values HTC has decided are not the maximum possible values , because I assume they would have designed the phone to handle few exceptional conditions (i.e: extremely hot weathers). But I think over clocking would probably cause more problems in the long run than whatever the little gains you experience in short term. Just my 2c.

Late reply, I hope you'll read it anyway
I tried faux 007b5, so overclock free too, I had 1.55ghz indeed, but never for quadcore, just for single or dual. Sadly I wasn't able to reach 1.5ghz quadcore but 1.4
With 007u, I have 1.5ghz quadcore, but 1.55 is an unused frequency
Can you check, with tegrastats, if you reach 1.55ghz quadcore or only for 1,2 (or3??) cores?

ElementalX Kernel OC

I am using ElementalX kernel on stock 4.4.4 android. I have to OC set to 1.944GHz currently. AnTuTu bench at 1.944GHz and 450MHz GPU gives me between 24-25k result. Now if I lower the CPU to 1.89GHz it drops to 21k. And if I go back to stock freq I get 19k. Something does not seem right in the test results as related to the frequencies. Question is this: Are there sweet spots in the frequency range for the CPU?
P.S. I know many people dislike benchmarks...I'm using it for comparative purposes...

You should monitor your CPU temp and frequency while benching.
You would see that your CPU's temp probably goes above 70°C if not higher and so the kernel thermal throttling policies would downclock your CPU's max freq. in order to keep your CPU "cool".
If you first bench @ 1944MHz then bench @ a litle lower frequency and have very lower score then its not because of the lower freq. but because you did first heat up your CPU @ 1944 and when you re-run @ lower freq. your CPU is already very hot and so does a severe thermal throttling.
Last point : running your CPU @ 1944MHz is not good since thermal throttling while happen every now and then.
Not convinced?
Then simply launch the camera app and try to take a video of 5 mins...your CPU will become so hot that it will downclock to something ridiculously low and your recording will become jerky.

Of course it operates at lower voltage as it's a lower frequency and requires less power draw. Lower voltages should mean lower heat, however you don't magically get that lower freqs to operate, you need to tweak the interactive governor to make use of them all efficiently. So far I'm on Kirks kernel and AOSiP and it's a quite good combo.
The lag is not caused by low GPU freqs, it's because of low CPU freqs for that particular load, so governor tweaking is needed.

Lol, I tested what you said out. Because you said it with such confidence...
I changed the cpu governor to performance and set the gpu to 160mhz max...
That made the experience a bit better but it would still lag a lot in recents and app launcher scrolling...
I've attached a screen shot to prove it too...
Another thing, just because the clock is lower does not mean that the voltage is lower as well, many devices that ive owned over the years have had the same voltage's for lower clocks( moto g2, Sony xperia z1)
And lastly, you should "magically" get those lower frequencies(if they are truly unlocked) since governors will always operate within the min/max frequencies that are set by the user or by default(unless it reverts parameters back to stock, like our device does on interactive)...

First of all, we are talking here about difference in voltage between stock minimum freq for big cluster, which is 1.1ghz and actual possible minimum which is 300mhz, and there is a difference in voltage, that was the point. The devices I owned, S5 and Z3compact had more CPU steps, therefore the difference between some of the steps was really small or there wasn't any, but the CPU scaling made a jump to the freq with bigger difference (higher or lower, that was the stock behavior so some freqs weren't used). Here it might use all of the freq steps as there are less of them and the difference in voltage is significant enough, which might be the case, I said that because of my experience with previous devices. But you've missed the point anyway, I have said that even if unlocked, some freqs won't be used just because they are there if the governor parameters aren't set properly (or will be barely used). That was my point, I said that as a general note, so users won't jump the gun and blame devs for whatever.
And another one, regarding your test and lag with GPU, now I'm confused why would you set your max at 160mhz? I know it was for testing purposes in this case, but you did complain about it in original post and I said it won't lag because the max would still be set to 430mhz in which case the GPU freq scaling would do the job which it does very good so far. It would lag of course if you set max GPU freq to 160, but that's not what would you do for daily usage, right? Sorry if I misunderstood something.

I kinda get what you mean, but the min freqs should kick in by default. They don't though on kirks, you need to change the governor to something like alucard or zzmove once before it actually starts clocking down to 300mhz...
On a side I would just disable the big. Cluster if I could, I don't really need that much cpu performance...
I was trying to find the min gpu freq that would be usable and I was disappointed, cuz my Sony z1 had a smooth ui experience with the gpu clocked at 200mhz max and that thing had a sd800...
Btw, I do all this to get better battery life...
I found out something else, I can't use power save governor any more because it can't handle audio processing(ainur, v4a) when the screen is off...
Just like my old z1, Lol...
Makes me think that the performance is really identical to the snapdragon 800...
I wonder how pissed I would be if a I got the redmi 5 plus, the 625 would have been even worse...

Yeah I agree, it should, but how much it stays on minimum freq is dependent on couple of governor parameters (talking about interactive). On mine though it does stay on 300mhz when idling, on stock Kirks settings. Big cluster can be disabled through new hotplug solution, like Intelliplug, which I used on my old devices, and it performed great, 1 core was active when screen was off, screen on and light usage required only 2 cores, while all 4 were active under heavy load. Here however there is only Qualcomm's hotplug solution, until that changes, no luck. Regarding GPU freq, I don't think any device would work smoothly under 200mhz, you can set 266mhz here, it will be smooth, I've tested today, on my old SD801 it performed at 233mhz IIRC.
I've seen that, V4A requires higher freq than 300mhz, or even 422mhz which SD801 had, it's more about the freq rather than the chipset, as I've read on multiple threads that even the devices with SD820 were struggling a lot when processing audio at 300mhz when the screen was off. Don't worry, it's a general issue. There is also the optimization of the rom and audio mods as well, background tasks, kernel, it all goes into the mix.
This is actually a very good chipset, it's technically SD660 just with lower clocks on both CPU and GPU.
EDIT: I forgot, this is my usage on AOSiP + Kirks, stock interactive tunables, min freq 300mhz (big/little), GPU initial/min freq 160mhz, max 430mhz. Using microG instead off GApps, I have used FB, Instagram, Messenger app for 1,5h each, Viber was couple of hours, Chrome some 30mins, Panini sticker album 30+ minutes, 30 minutes of 2G calls. Network mode was LTE, though I was on wifi on whole charge.
Started measuring from 92%.
Thanks bro, that explains a lot...
