Can faster CPU chips get away with lower volts? - Verizon Samsung Galaxy S III

I guess my title says it all. I can get away with like 750 maybe at the two lowest volts for ktoonz but 775 for sure and pretty gradually work up to about 1150 at 1512 and the lowest I can take 1890 is about 1260...i guess that's some background info..
Side question, can undervolting create lag? One kernel I used with similar voltage to what I used with ktoonz lagged like crazy but ended up being okay later, kind of strange actually. I know it causes reboots but never experienced lag, extreme lag like it would take like 5 seconds to respond..
Meh, ktoonz finally got around to catering to 4.3 and I'm back to sub 800 without lag...k I'm done rambling. I guess all that needs to be said is yes or no.
Thanks

If ur lagging while undervolting that means you are undervolted to low. Basically the CPU isn't getting enough power. Just increase +25 or +50 across the board should fix lag

That was an isolated event. I tried the same volts later with the same kernel w/o lag.
But judging by your response faster CPUs can run on lower volts?
Almost seems counterintuitive but I'm no computer science major.

I'm confused by your question. Run on lower volts compared to what? Any CPU can be undervolted. Remember each CPU is different and some will undervolted farther than others. Are you asking if a quad core will undervolt more the say the snapdragon pro 600?

GPU overclocking

Does anybody know what it takes to overclock the GPU in the Droid Charge? I generally think that CPU overclocking is pointless, but GPU overclock should help terrain data in Google Earth. I have lagfix installed and verified working.
I am currently on the underclocked PBJT kernel. I assume I would have to migrate to the overclocked PBJT kernel, but I don't know of a way to control GPU clock from there. Ideas?
After installing the OC PBJ kernel, download and install an app called Voltage Control.

There's a difference between the CPU and GPU. Voltage control only changes the CPU clockspeed. You would have to ask imnuts if it's possible to oc the GPU.

No. If you see the FPS waver, then it is not at its FPS cap, therefore it would be pointless to raise the cap.

RAM makes everything better and it's the reason why certain apps seem to be quite slow(n64oid, gun brothers, etc). If those ****heads over at Samsung would've added more RAM this phone wouldn't have any problems, sure a better processor and a notification LED would have been nice but the only thing actually needed was the RAM.

The requirement for more Cowbell aside, does anybody if this is possible? The Galaxy Nexus will have the same GPU but clocked at 384 MHz vs 200 MHz on the Droid Charge.
I am curious if they have somehow reduced the process size or added extra cooling capacity, because that is huge difference.
In any case, it makes me think that GPU in the Charge could use a bump up without causing issues.

Holy dead thread batman! At any rate we can't increase GPU clockspeed because it's probably controlled at a hardware level, rather than variable by kernel.

I do believe the glitch kernel on the fascinate does include gpu overclocking. No idea if that could ever be implemented on the charge. If it could it would probably have to be an MTD based kernel like glitch that is currently for MUIU and Cyanogen roms.

All of my phone gpus have clockspeed dials on them.
And not to be even more of a smartass but the kernel is in fact the exact piece of software that interacts with the hardware so you kind of contradicted yourself.
It has been done with glitch kernel. Haven't seen any tw kernels that support it.

I meant that we don't have anything in the kernel that can adjust the clockspeed. I don't really know about any other phones since this is my first smartphone. I just say what I feel is correct. And yes, we may eventually be able to control it through an AOSP kernel, but we don't have that right now, so I don't think it's relevant information.

Chocolate Ice Cream Sandwiches?
I came from the Fascinate and the Glitch Kernel with CM7 was really rocking. If we ever get GPU overclocking it would very likely come with the same combo or a Glitch CM9 combo either of which is a long way off.

Correct me if I'm wrong, but it sounds like what we would need for this to work is a working ASOP kernel, thus we would need an official Gingerbread OTA update first (maybe not 100% necessary, but it should be easier?) in order to base the kernel on?
Even with a working ASOP kernel, I assume that it would have to be specially modded to allow GPU control.
Not that I expect CM7 or CM9, I'm pretty happy with the latest leak, but it seems that CM7 or CM9 would more or less be a requirement for this to work? I hear that MIUI is not in development for the Charge because the lack of LTE in China.
Keep in mind that the Charge is my first smartphone so I'm sort of a nube.
Big thanks to the devs who turned this phone from crap into gold!

[Q] NS4G Heat Problem

My Nexus S 4G seems to heat up very quickly. While I was expecting this behavior during excessive 3g/4g use, I was NOT expecting it while reading PDFs on my phone. I am using the built-in ThinkOffice to read the PDFs, but the phone always heats up after 10-15 minutes of use. Has this happened to anyone else before? If so, what is the solution?
Currently, my phone is rooted, with 2.3.7 stock ROM w/ Apoc-Talon v 2.1 kernel, overclocked to 1440 Mhz w/ Smartass v2. The heat problem has also happened while my phone was running a stock 2.3.4 ROM on the Netarchy kernel.
Its your kernel. I'm running cm7 at 1440 too and my phone never gets past 110 degrees Fahrenheit. Even while tethering which surprised me. When I tethered on my epic it would get hot enough to fry eggs. Even when downclocking to reduce heat. Just a hunch

Even if your overclocked it doesn't mean your gonna overheat. The CPU scales. Remember that. Its not like its running at 1440 all the time. Ive been running at 1440 ever since 7.1.0 came out with absolutely no overheating or lock ups.

You can't dispute what I said. Because you are able to overclock to 1.4 without issues he should automatically be able to? Are all cpu's equal? Take some time to think about it.

Of course. But that wasn't wwhat you said. You said overclocking needs higher voltages. Understood. I was only saying that the chances of his phone overheating because of ocing is slim. As far as I know only benchmarks and a few gpu intensive games will push the phone to run at 1.440 ghz. The CPU scales and barely even touches 1.2 ghz. Floats around 200 and 800mhz for the most part. I'm deducing this from my own usage and keeping an eye on the CPU with cpuspy. My point was that ocing wont do this unless he's actually pushing the CPU that far or setting the governor to performance. Which from the looks of it isn't the case

Now that I measured it with a battery app, the temperature only goes up to 107.6 degrees...guess it just seemed really hot to me.

My tablet is still locked so I don't have experience regarding frequencies and voltages with it. But my phone reboots in CPU intensive tasks when I lower the voltages too much (as with PCs). Since every CPU is unique you need to find the right combination for you. Be careful not to fry it.

How high can you overclock? Any tricks?

I was stuck at 1890 for a while then I flashed paranoidandroid after having reboot issues with pacman and am able to run 1998 with pretty decent stability. I'm getting some graphic glitches but pacman wouldn't even come close to as stable as I am on PA. I am super undervolted as well, with 81 mhz and 135 @ 750 and I gradually up my voltage. The only one I left as stock was 1998. I don't know if I'm doing more harm than good, though.
A few times I oc'd to 2106 and it didn't immediately reboot so I have a feeling I might be able to make some modifications and possibly run stable there, any advice?

He is using kt747 kernel it is kinda obvious since that is the only one with a ktoonservative governor. Overclocking isn't really good for battery life but oc at 1.6 to 1.8 ghz with it undervolted and apps like greenify and DS battery saver should help compensate for increased performance.

The real question is why not? LOL. Honestly though I just like finding new things to do with my phone and coming from a locked Galaxy S4 I have to say I'm enjoying the amount of things I can do with this device that I couldn't on the S4. The extra 600MHz was because I was hoping it would drop any chances of lag with my favorite apps & Xposed which always seems to cause a delay or two for me. On the other hand I like squeezing what I can out of it. Same with my Desktop too, get maximum stable over clock and stick with it. ;D. If there's some downsides such as life shortage feel free to mention it though because I'd rather know early on than when it's too late. Sorta the point of this thread

I've got my i5 2500k overclocked to 4.3 GHz now stock voltage . As for life shortage its hard to say. I would monitor temps on stock vs over clocked and compare. As long as it doesn't get considerably warmer which for mobile would be 10° more or less you should be fine

Well with normal use it gets like 40-55 C (CPU) and during an Antutu benchmark just at the beginning it hit 75C sooo not very happy with that.... especially considering that's in the highs for a lot of desktop processors, can't even imagine how bad that must be for a phone processor LOL. It was @2.803 MHz with voltage of "1130" & ondemand governor. Not so sure as to what "1130" is based on though as I'm new to mobile over clocking, guess I'll figure it out tomorrow!
Edit: Forgot to include that just a few minutes ago I flashed a new kernel due to some random lag, old one never hit above 50 even on tests (with intelliactive). Also using ondemand/interactive now. Gonna re check the differences on those two governors tomorrow and decide which one I wanna go with! : D
