[Q] GPU Overclock??

I'm not sure quite how it works, or if the galaxy s series has the capabilities to do so, but can the GPU be overclocked? All I know is that its Cortex-A8 chip is 3 times faster than the snapdragon, and supposedly runs cooler... So is the GPU and CPU combined into the single hummingbird chip? If so, would the 1.2ghz OC clock up the GPU speed at the same time? I know that this phone is a beast already, but it would be even more fun to have this thing clocked up to 1.6ghz and if the GPU overclock is separate, maybe that can be done too...

I'm usually pretty supportive of overclocking but I think its pretty useless to overclock the gpu at this point. The captivate's GPU is faster than the GPU that will be in the next generation OMAP4/Cortex-A9 processors. There is simply nothing meaningful that can even tax the Captivate's GPU right now.
If past phones are any guide then the GPU can be overclocked and it is a separate clock from the CPU.

this is a video of the iphone running a 'rage' demo.
the captivates processor handles graphics slightly better than the iphone 4, and the iphone 4 is also underclocked.
so the captivate is capable of these graphics and more without overclocking.

Is there any chance we'll be getting the GPU drivers ported over from the Nexus S? CM7 and MIUI are apparently using them, but those ROMs are still too buggy for me. I wish we could be them going on a KH3 ROM.

Have you tried cm7/MIUI lately? Not nearly as buggy as they once were. Still a few wrinkles, but stable as a daily driver for a lot of people.

I felt that for long time and waited on the cm7/miui train for a while. I'm now running miui and love it.

Ya I was on MIUI for a while, but people complained about the phone quality when talking tom me. I switched to a KH3 for the audiance chip. I do miss the snappiness even with the FCs. Was hopeing to have my cake and eat it too.

[Q]Hardware-wise, will OB be able to handle ICS

I am wondering if the LG OB hardware specs will be enough to have a fluid experience running ICS. Given that this device has only 512MB of RAM and a single core 1GHz CPU, do you guys think we could have an overall good experience running ICS (e.g. no lagging)? CPU IMO seems to be the least of the concerns, but what about the RAM capacity? I've read somewhere sometime ago that Google stated that any GB capable device, would run ICS with no issues, but I've also read in a forum that 512MB is the minimum required to run it so we might be on the edge. What do you guys think?
Important: This is not a thread to discuss whether or not LG will be pushing out the ICS update or when so let's try to be focused on the topic.

I am certain the Optimus Black has adequate hardware capabilities to handle ICS.
Apart from CPU and Ram, GPU is the next criteria for ICS which demand 2D acceleration to be handle by the GPU.
It is just up to LG / Cyanogenmod community to bring it to life.

it can handle...otherwise it wouldnt get the official update!

Keep one thing in mind that :
"Any device that can run Gingerbread can also run ICS" (according to google).
Its not possible when we have useless TouchWiz like Samsung bcoz it takes alot of RAM
I actually sold my Galaxy Tab when I heard that Samsung will not be releasing ICS for Galaxy S or Tab while it was only 9 months old !
So its useless to have a device that has no future support from manufacturer.
Millions of units of Galaxy Tab & Galaxy S were sold worldwide & Samsung embarrassed millions of user by just making excuses
Plus if mid-range Sony Ericsson phones can run ICS (via official update) then why now Optimus Black?
Come on guys it has 1GHz CPU.

Well technically the Black doesn't have 1 Ghz processor, it's just factory overclocked to reach that.
As for ICS, I wouldn't expect the official update to be out until 2013

I think the OB can handle ICS very well.
If the GT540 (my old phone) is able to run ICS (still BETA but it works) then
i see no difficulty in running ICS on the OB.

OB is certainly able to handle ICS since Nexus S is able to use 4.0 with the same specification to OB. (1GHz CPU, 512MB Ram, but more powerful GPU SGX540)

yes, Galaxy S has some full working ICS ports, also on Galaxy SL i9003, which has the same hardware as our OB, there are some devs working on ICS

Theoretically yes. But will there be a stable and usable ics rom is another question. I am pretty sure before that I would be with another newer phone already. Now let's enjoy gingerbread first.

ICS needs 1ghz cpu & 512 mb gpu. the black has both. i don't know what will happen with the stock ics as it will have the lg bloatware & the optimus ui, but with AOSP projects and trees like cyanogenmod,i think it can not only run,but run very well on our black.
and btw, the black uses tiomap 3630 & cortex a8 combo, i think it's stock 1ghz and NOT factory overclocked. the 3610 chipset would have been overclocked 2 get 1ghz, not 3630.

My Nexus S runs ICS AOSP+ 4.0.3 + M4trix Kernel flawlessly & very smooth. I also can OB & NS have similar hardware configuration, so it must be supported! CM9 already on its way afaik

I think OB can handle it as LG stated it in their schedule of ICS upgrade for their optimus phones.

If you peek at knzo's notes while developing his Nova, it is factory overclocked which it explains why the Black is never stable when overclocked to 1.2Ghz and above. Here's another android phone using the very same processor clocked at the stock speed: Defy.
Just to be clear I'm not sourgraping but CM9 may just be our only hope for ICS (at least ICS before the end of 2012).

Since there is an ICS Beta avaiable for the GT540 (600Mhz) i think the OB will do just fine

now who went on to tell you ics requires 1ghz and 512mb... google for android developer phones and you will be surprised at the minimum spec needed for ics... these are the phones on which fw are developed and it is required that fw runs on them smoothly... the minimum reqs are so low that even 600ghz 256mb can handle it...
ps:no gpu required too

Ricardo said that every device with 512 MB ram and more will be supported by CyanogenMod

in regard to my previous post (2 posts up) current dev phone is htc magic with only 192mb ram (unlike the 288mb that aired the market) and 528mhz arm cpu so that means ics was developed and should run on it. The galaxy nexus is the advanced dev phone and that is a totally different matter. This means that black will be more than adequate to run ICS compared to the htc magic's specs... It would be lame to asume that google is developing towards the high end users as even as we speak 1ghz is starting to become the standard on market and still it isnt if you look at the low end devices that are released out there still... There will be still some time till 1ghz/512 ram are considered the standard (not by users but by companies that is) so it is safe to assume that you will be ok for quite some time with black (and me with o3d). Hell my kid's huawei joy (aka vodafone joy845) has beta versions of ICS running and it is th lamest phone I ever layed my hands on.

Vellamo benchmark better on ICS/JB, but user experience better in GB...

There's something I don't get it. I have been playing around with CM10 (JB) and Minimoto (GB). Using Vellamo scores as indicator, the performance in JB is much faster than GB. HTML5 scores of 1400 (JB) vs 600 (GB) and CPU scores of 400 (JB) vs 370 (GB). However, that does not translate into user experience.
CM10 is supposed to fast and optimized for speed, but I am getting serious lag. OS is not very responsive to touches, apps take a good one second longer to open than in Minimoto which is GB-based. Isn't ICS and JB supposed to have additional hardware acceleration that GB does not... so why is Minimoto outperforming CM10? I also frequently manipulate spreadsheets on my phone, and the scrolling performance is way smoother on Minimoto than on CM10. What's going on here?

The reason is RAM. There isn't enough really unless you set it to strict memory management.

It's not the RAM. Samsung Galaxy S has the same amount of RAM as the Droid 3, and it's more responsive...

Kexec Ducati is not memory efficient.

^ what he said, kernel just isn't completely optimized for our phones yet.
All that new hardware acceleration takes code to make it work
Something quick u can try tho:
Depending on what kexec kernel compile your using you can try switching cpu governor from interactive to ondemand or one of the other choices.
Certain builds have it disabled, otherwise its set as default
interactive is buggy for some reason and causes crashes/some slowness.
I know it helped me a bit, even though it uses a bit more battery.

Thanks, maybe I'll dual boot/flash a CM10 and try full performance, but with battery issues and camera issues, I don't see how CM10 is stable enough for daily usage.
What's the point of running ICS/JB if the drivers are not optimized and/or if you need to force it at full performance mode to get acceptable performance? Isn't moving from GB -> ICS/JB about performance improvements?

Has Anyone Overclocked Jelly Bean?

I've been a reader of this forum for a while. I've finally regained root after losing it during the update. Thanks Marty for the root exploit. The main thing I like to do with root is overclock. Has anyone achieved this? I see benchmarks that show it has been done on the Bionic running JB. Thanks!

Anyone? No one? Will the method they're using for the Razr work?

Has anyone here overclocked a Bionic on Jelly Bean? If you have, please point me in the right direction. Thank you.

As far as I recall, 1250mhz is as high as you can get on this hardware. You should be @ 1200 already, so I imagine the difference would be negligible.

I was running 1370 stable on ics. Just need a kernel I think.

Have you tried this?
http://www.droidrzr.com/index.php?/topic/16813-[KEXEC]-Code-Kernel-4/24/13
I couldn't get it to show the higher frequencies but maybe you'll have better luck with it
It lagged for me, it defaults the min to 100 and couldn't get 300 to stick.
Others have had better luck

Overclocked at 1300 right now
Currently I am overclocked at around 1300, 1400 made the device freeze. I achieved this by installing a custom ROM, if you go to Motorola Droid Bionic > Droid Bionic Development > Blurry 2.4 and install that rom, it has built in kernels that allow overclocking.

Sorry for being a noob, but how do you overclock it? And is their a difference when its overclocked?
Sent from my DROID BIONIC using xda app-developers app

Over clocking to my understanding is a feature that some kernels have along with additional scripts added. I personally use Motomizer Expert to set the CPU values to above normal (my values originally were 300, 600, 800 and then 1000) I have it overclocked to where my processor runs at 1300. I then set the value to the maximum using SetCPU. All it does is make your processor run faster than normal, making the phone snappier and faster overall, not by much, but enough to notice. I hope this helps, and keep in mind I am also a n00b, so if I am wrong, I'm sorry and maybe someone more knowledgeable can help you.

Thanks for all the responses. I'll try changing the kernel first, if that doesn't work; I'll consider the rom. I like the way everything runs with Jelly Bean, I just love to tweak.

The kernel is difficult to change till the boot loader is unlocked (most likely will never happen). Of coarse kexec kernel is the only way for now.

More Input
I have tried the Kexec Kernel, unfortunately, it allowed me to underclock to 100, but it wouldnt allow me to set any values about 1000. That is when I started looking into OC'able ROMS. and Blurry is the one I liked best. AOKP is nice, but it didn't have the kernel built in. I have not tried Liquid Smooth and CM 10.1 was just not for me. Hope this helps.

Ok. I may look into the Blurry ROM.

OC Kernel >1.5 Ghz for CM10.1 ?

Hello!
I was wondering if someone could provide a kernel running at a speed above the 1.5 Ghz?
I think to remember that Maromi already offered a kernel with 1.6 Ghz but due to freezing issues (smartflex?!)
it's not available anymore.
Actually I'm having the 1.5 Ghz (thx to Maromi and Hashcode by the way!) running on the last CM10.1 (06/04)
with persanos tweaks (thx to him as well!).
The device isn't getting hot even while playing games, watching movies or running the Antutu Benchmark (~9200)

Hummm... I would use Hashcode's kernel but i'll see what else I find and get back to you.

Yeah, maromi and Hashcode have the lead on the kernel thing. They have been working together to provide the 1.5 ghz kernel. As far as I know it is the only stable OC kernel for Kindle. I remember I think it was Hascode said the Kindle actually isn't even meant to get up to 1.5, so to go higher than that probably not, and I think it was maromi said basically it was a fine balance between OC and heat issues and 1.5 ghz is really pushing the upper limits of the cpu. So just taking a guess, but probably won't see higher than 1.5.

I think the smartflex thing had something to do with the voltage tables of the CPU and I also read that maromi had a 1.7 but never released it. The overheating issues had to do with the smart flex being turned off but hashcode fixed that with a new voltage table for the 1.5. So I'm keeping my fingers crossed they can release something higher that is stable and doesn't overheat. I'd test it.
