[Show off] Overclocking the octacore GS4

[DSWR]

Hopefully this would be available to the i9505 version ^^

GT-19000 only, I'm afraid. Unless you become a guinea pig for my testing, haha.

Not going to risk my $900 device for testing

So what u did was overclock all the cores (8) at the same frequency !! thats awesome
so it means that u clocked the A7 to clock to 2.8ghz thats actually 125% more of what the Samsung believes to run it !!
Thats just awesome !
also is it that using all 8 cores at a time save battery or rather drain it ?
did u tried to overclok the snapdragon version?

Was worth a try

The battery life is exactly the same. Will only be effected once it goes over 1.8GHz which is then the unknown. I haven't tried overclocking the snapdragon version but a mate of mine managed 2.5GHz on it last night

It's cool how the battery life can be the same despite the monster processor.

There are some ingenius ways of overclocking, then there's the proper way If done right, you can keep your phones battery exactly the same, obviously once it goes over so far, it may require that little bit more. I'm working on it all again. Currently running stable at 2.4GHz but the phone is clocked to 2.8 as before. Undervolting quite a bit so I've got the same battery levels as a normal user.

Cool. Cant wait for the i9505 version to be released.

No Antutu or quadrant screenshots?

You mean benchmarks?

DSWR...
Nice and interesting post.
I have a question. This Octa-core processor supposes to offer a more optimized and energy saving performance using both sets of cores, so have you to try to improve the battery life playing with those cores and a customized software?

Thanks...

I Wish i had the cojones to push my s4 and my s3 this far.Good lord 2.8ghz is the stock speed of my i7 930(which i have OC'ed to 4.2ghz )

Since my previous geekbench test... I've managed to get a "bit" of a better score, haha.

This is with the usual samsung software, so it maybe a bit higher than the truth. I don't go by performance due to big numbers, so this really means nothing. It doesnt' seem to handle games much better, although I ram running the GPU at 750MHz instead of the crappy 350 so I've noticed a massive FPS improvement. For those asking for Antutu and Quadrant, I haven't really bothered testing on them as previously mentioned, benchmarks mean NOTHING, so I don't intend on uploading more. I'm stopping my project as of today, well, for now as I've got a lot of money problems at the moment due to my motorsports racing. Feel free to continue asking questions and all that as I'll still reply and will let people know when my work starts again. The Kernel is still unstable, meaning the power laggs out touchwizz completely and will give it a large delay most of the time. Can usually get 10 or so minutes out of her. Need to make the system understand that it doesn't have to run on 2.8GHz all the time (as it currently is) and to move up and down as you'd expect normally, but that's for another day.

It is impossible to measure CPU frequency accurately with geekbench or other third party app on a Big.LITTLE configuration.

Care to share your kernel?
Or another benchmark(like antutu or quadrant) which does show the performance of your CPU.

Also GPU is clocked at 480mhz not 350mhz and crashes when over clocked above 640mhz.

You can get the full 700 if you know what you're doing. Thanks for the input though. It will run at 700MHz but it is NOT stable if running at it for a long time. You'll get a good few minutes out before it reboots.

Here's a VIDEO of it on geekbench. I'll pay for quadrant and do another benchmark test when I get time.

Hi DSWR,

I truly feel you are indeed a genius and I think you are the only one in the whole world to achieve this, you should probably be with Samsung and help them to get the best out of their devices .

I Just want to make my phone a little faster . so i was thinking of overclocking the Cortex A15 Quadcore from 1.6GHz to 1.9 or 2.0 GHz.

So I want my device to be very stable and fast , we know Samsung has kept a lower threshold value for safety and stability but I think A-15 Cortex overclocked at 1.9 GHz would be equally stable as well.

So if there is a link you have which shows how to overclock the S4's A-15 Cortex @ 1.9 Ghz please do share .
If you can please test your phone overclocked @1.9 Ghz , play games, test it , run benchmarks then finally share it , it could be of tremendous help to many.

Really appreciate your commitment time and effort to make our world with smartphones better.

Thank you for all the work you have done and all the work you are about to do.

We really acknowledge and appreciate your work and contribution.Cheers !
