1.5 or 1.6 ghz kernel?

Is this able to be done and if so how do u go about compiling a kernel??
Sent from my SPH-D700 using XDA App

Yes it is able to be done.
Sent From My Evo Killer!!!

I've seen the 1.8mhz custom kernels over on the EVO SHIFT 4G thread and the stock speed of that kernel is only 800mhz...and if they can push that a whole ghz past its regular operating speed...then I don't think 1.5 or 1.6 would be out of the question...id love to see that (HINT HINT TO OUR DEVELOPERS!! ;-)).

The problem that needs to be overcome with the current 1.4 kernels is that we're already at the top of the voltage specifications for the CPU (per manufacturers dox anyway) to keep the phone stable at 1.4. All chips are a little different - some phones might be stable with less voltage at this freq or others might be able to handle a little more juice. But, we're already at a 40% overclock... How fast do you really need this thing to be?

I personally would not use it if it was overclocked that high. That is to much for it. And the Shift has a different chip in it so it can be different overclock.

Moved to Q&A. And it can be done if you want to fry your phone

Some phones can't even handle 1.2ghz cause of the ****ty silicone on there chips. This includes my phone .
Thomasskull666 as a 1.4ghz kernel released to the public but he has a private kernel at 1.48ghz. He's trying to get a 1.5 for the public. The 1.6ghz we had on eclair was found out to be a placebo cause of error in the coding. With the phone clocked at 1.6ghz it actually ran at 1.0 and the rest of the phone slowed down. It was like those cartoons and you see a man walking at a steady pace but the background was moving at warp speed.

That just seems too fast for this phone. Personally 1.2 GHz seems fast enough while 1.3 GHz is just a nice little cherry on top in terms of speed.

[Q] Poor GPU performance with my Epic 4g

I'm having some trouble with GPU performance with my Epic 4g on stock EC05 with the Genocide 2.0 kernel.
From my research I conclude that I should be getting ~45-50 fps in nenamark1 v1.6 at stock clocks.
My device can only push out 38fps at 1000mhz and 40fps at 1300mhz - something is wrong here.
I have tried the Syndicate frozen 1.2 rom with the Genocide kernel and achieved the same results. I have since gone back to stock rom.
Does any one have any ideas as to why I am getting such low scores.

yeah i tried on srf 1.2 and actually got 30.3.

ok srf 1.2 oc'ed to 1.4. are you sure your actually overclocking? download a program called cpuspy and see if your actually hitting 1.3
edit: btw i odnt think its possible to get any where near those kind of fps without overclocking..

yes, 41.5 fps max at 1.3ghz Something is wrong. shadow Guardian is fairly choppy as well.
My gpu is gimped...

Which Governor? If using "conservative" I don't think it tops 1000 or 1120 even if overclocked to 1400 unlsee you use the very first Voltage Control. Rodderik doesn't support the new Voltage Control or SetCPU. I brought this up to him a while back. He said to use the Voltage Control in the OP of his thread. Just trowing thoughts out there...
Sent from my SPH-D700 using XDA Premium App

I only know how to change the governor with setcpu, I don't see a way to do it with voltage control.

My CPU is fine I think. SetCPU also works fine to change the governor. Running the short bench, the lowest result on stock was about 181 ms. Overclocked to 1.3ghz I got 136 ms.
I'm also getting great speed in CPU intensive applications like the n64 emulator n64oid. GPU limited apps like Shadow Guardian and Quake 3 aren't doing as well.
I wonder if my gpu is somehow on power save mode (if that's possible)
Can someone compare their setCPU short bench results to my score of 136 ms?

More or less what I'm getting. I doubt your gpu is gimped man. And your cpu is deeply integrated with your gpu. Don't think of it like a desktop setup think more like a laptop. Where the gpu is supplemented by the cpus power. 41-44 fps would be normal for 1.3 ghz. What I get at least.

I know a hell of a lot more about notebooks than I do about android phones, and even integrated graphics chips are independent from the CPU. Sure they may be manufactured on the same silicon with the cpu but they can be clocked independently (and even turned off).
The problem with the epic - and android by extension - is that you don't have direct access to the GPU or its driver. I've read that some kernels for certain phones can allow you to overclock the GPU; though none exist for the epic. An yes, I know about chainfire3d, and it's not really a 'driver'.
At least battery life is good for me...

As far as I know, this might be exploitable in GB, which is why you are running into problems.

What you said about graphics chips might be true.. But it still doesn't change what I said. The problem is not with your gpu. Its with your settings. You may prove me wrong, but what I said is that your gpu directly relies on your cpu. That's why you get a better framerate when you overclock more. Chainfire has nothing to do with this.. I'm sure you know this but its purpose is to fool games by converting "commands" for a certain gpu into another and downsampling textures, etc so that they can run more efficiently on our chips. Ask anybody else what they're getting on that bench and they'll tell you similar numbers at the clocks we discussed. Btw I'm not sure but I think the gpu drivers for our phones might be closed source. Which would explain why oc'ing our gpu would be impossible without custom ass drivers built from the ground up.

Defy Overclocking

Hello people
Today I bought my new defy and I'm testing the possibilities of the device.
After some misgivings, I've made a progressive overclock and hit the 3GHz mark.
Someone has already gone beyond that and know if the device remains stable? Here it is running at 3GHz for an hour and not warmed more than 1 º C and not spent too much power. And yes, he is set to keep the clock all the time.
Did someone made this as well?
Edit: I can't post the Screenshots 'cause I'm a new user. If someone are interested in it, I can send it by pm.

I went to 1ghz and no further... you must have money to burn (or phones to burn!)

The phone didn't overheat. Even after one hour at 3GHz, the temperature did not rise more than 1 º C.
I wonder if anyone else has ventured within the limits of overclocking.

Even at 3GHZ, there's nothing gain as no apps or games need that power to run at the moment. All apps and games would run smooth even at 1GHZ. Possibility at this 3GHZ is only a fried processor if the phone won't do the auto shut down.
Sent from my awesome Moto Defy: Stock Rooted Gingerbread 2.3.3 - XDA Premium

It's still on and working without overheating, but I noticed the needless of this clock
I'll set the clock for 1.5ghz.
What rom do you recommend to me? I'm using Cyanogenmod rc 1.5.

3GHz is impossible, over 1.5GHz CPU can't work, you can set 10GHz, but will be exactly the same as 1.5GHz

May it be 3.0ghz only on the display but no in the system?
I'm new on this phone and don't know so much about it

3GHz? Hehe!

Yes, on screen it's shows 3GHz. But, like bvbfan said, I think it's only on screen and not the true frequence of the clock.
What program I can use to check this?
I'm using CyanogenMod Rc 1.5

Im running my Defy on 1 Ghz for ages now.
Never had a problem and i think going any further will not be healthy for your phone especially when you increase the vsel over 58

however you make it happen, it is fake. simply because of no heat. it is not really 3GHz, just a number you see on screen. run Quarant and see if it is really 3GHz

The current kernel won't let you overclock anywhere above 1.3 ghz. Its ARMv7 CPU limit I believe.

Just download SetVsel from Play Store, then search in Google for Defy overclocking.

Overclocked Since 1 Year
I am using Aero Control with the following settings:
GPU freq : 266MHz
VSEL Levels:
400/34
800/44
1100/56
1300/66
Governer: Interavtive
Current ROM: CM11 by Quarx 2
Kernel: 29/7 kernel by Blechdose
It is stable. No heating issues whatsoever :angel:

Is the phone stable when overclocking past 1.3ghz?

I heard there was a problem with stability issues before. Has it been fixed?
Also, do any of you guys feel the need to OC in the first place?

I tried OC'ing to 1,4 for a short time, didnt get any instabilities.
Which leads me to question two. No I don't feel the need to OC this phone, it is still good enough to cope with everything i throw at it.

The worst that will happen is that it will run a little hotter than normal. I was running Trinity Kernel on RasCream ROM clocked at 1.5GHz and it was fine, nothing crashed, no reboots, all was well.
Besides; It's a Nexus, it was built for this!

This varies for everyone

Meh. It all varies. No 2 chipsets are the same. What may work for someone else may not work for you. Trial and error is the only surefire way to find out.

Hi,
I agree with what has been said above, all the CPU's are not equal but actually the progress made by the kernel devs allows all (or almost) phones to run at 1.3* Ghz (1.34/1.35 Ghz, it depends of the kernel) without any issues.I think it's for all, actually I don't remember a user with issues at 1.3* Ghz...
And for most phones 1.5 Ghz is fine.For some others, above 1.5 Ghz is problematic but it depends also of too many factors.
Now it's not like it when the Genx came out, where 1.3 Ghz was the limit of CPU overclock for all the phones.
And many people can run stable at 1.65 Ghz, also it depends of the kernel.
For me for example my max CPU freq usable each day, so stable is 1.72 Ghz with Glados kernel, above (like 1.8 Ghz) it runs fine for 30 mins, sometimes 1 hour, but after always freeze/reboot... maybe my CPU can't reach this CPU freq or maybe my settings are wrong (voltage) ...
I agree, an extreme overclock like 1.72 Ghz is not really necessary for all day (heat, battery life, etc...) but a little overclock like 1.5/1.53 Ghz and you a difference in certain case (openning some apps, general UI, browsing, etc...).
But if we have the ability to test and play...why not... ,in any case for me it's yes, I like overclock and test the possibilities/limits of my phone, different settings...
Everyone does as he wants and it depends on what you want (battery life,a little more power in some situation like playing or a higher bench score ).

Well considering Texas instruments recommended highest clock speed for this processor is 1.5 ghz I'd say your fine. Anything above that is dependent on how well your chip set will handle it. Besides who honestly has needed to OC for anything other than benchmarks?

Will an Overclock to 1.7+gHZ be available?

I need it cuz I'll get a ONE x+ which has 1.7 preloaded. Also with loop device pls?
ATT PLS!

But I need 1.7 for special purposes.

Sorry, but I have to call BS on this. There is zero reason that you"must" have a 1.7GHz instead of a 1.5GHz regardless of which system is actually faster.

.... and 1.7 GHz is required for that, regardless of the chip architecture? I'm not a computer engineer, but I know that a 2.0GHz Celeron processor can't do anything faster or better than a 1.5 GHz i5 (even if there is a bigger number in front of the "GHz"). Processor speed only matter if you are talking about the same chip architecture.
btw... there's no need for name calling.

So... If I had a CPU that ran at 1.5GHz, there's no way the game could run on it, even if the processor/system is 1,000 times as powerful? Something simply doesn't sound "right" about that. We're not talking about requiring wavelengths of light syncing up or frequency of signal (if we were then computers of different frequencies could never "talk" to each other).

... and notice that the RAM in the phones is 4X the minimum required.
While we're on this topic, the GPU is far more likely to be your limiting parameter, than the CPU. You need to research that aspect (the GPU's in phones aren't designed to run TV's esp today's large form HD TV's).

Was playing around with LiquidSmooth, RootBox, and Houcha kernel in April. Also ended up purchasing FauxClock.
Some combination of those on some date allowed a CPU overclock to 1.7 GHz and GPU overclock to 487 MHz.
Wasn't interested in the overclock capability, so didn't mark down the dates or versions. But it's definitely possible.

It's is possible yet useless with our phone. Also, our chip doesn't like overclocking at all. Finally, the worth of energy loss vs performance gain is not good enough to justify using overclock.

Totally agree with you chad.
On this device oc is useless,you don't compare overclocking a galaxy s with an optimus g.
Not to mention it's not that easy,to find the proper voltage/freqs table.too much work "just for the heck of it".

Never said it was useful, just that it was possible.
Once you get above 1Ghz dual-core Cortex-A9/Krait/A7, everything is gravy, and it's the GPU or memory controller that becomes the bottleneck. Just look at how poorly the Tegra3 is...mainly due to crappy GPU and limited memory bandwidth.
