recently i came across overlocking GPU.. in sense4a built by derefas made GPU overlocked to 220 n he mensioned that its safe.. is i dont think it wont create any problem.. some problem ll exist.. can anybody know that problem?? and overlocking to 220 means now we have adreno220 ?? is it like dat?? n i google it but i saw that for adreno220 it clock speed would be 1.2Ghz to 1.5GHz(acc. to this site - http://en.wikipedia.org/wiki/Imageon). so that rom has gpu overlocked n cpu optional, it means iguess it make some problem.. can anybody explain me pros n cons..:fingers-crossed:

No, it ain't like that. The chip is embedded, and can't change.
Our Chipset is MSM7225A (according to http://pdadb.net/index.php?m=specs&id=3073&c=htc_explorer_htc_pico) and the GPU supported is Adreno 200 (enhanced) according to (http://en.wikipedia.org/wiki/Snapdragon_(system_on_chip)).
The Adreno 200 was said to support the following in the wikipedia site.
Adreno 200 (AMD Z430) inside the QSD8x50 (1 GHz) and MSM7x27 (600 MHz A11+L2 cache). It offers a programmable function pipeline and streaming textures with support for OpenGL ES 2.0, OpenGL ES 1.1, OpenVG 1.1, EGL 1.4, Direct3D Mobile, SVGT 1.2 and DirectDraw. (22M triangles/second, 133M pixels/second, clock speed up to 128 MHz).

Even some googling didn't help in finding the clocking speed of our GPU. According to wikipedia, it supports 128 MHz.
Note that it was for the devices QSD8x50 (1 GHz) and MSM7x27.
But, an enhanced GPU is supported in our Chip. So, I got the following info from the Qualcomm website.
Adreno™ 200 is the first OGLES 2.0 GPU with unified shader architecture and makes maximum use of the graphics processing power of the GPU. This GPU is a leap forward in visual graphics quality from OpenGL-Es 1.x, which enables developers to implement effects that were previously a daunting task. APIs supported include OpenGL ES 2.0, OpenGL ES 1.1, OpenVG 1.1, EGL 1.3, Direct3D Mobile, SVGT 1.2 and DirectDraw. The Adreno 200 delivers streaming textures to combine Video, Camera, SVG and other image surfaces with 3D graphics. It also enables concurrent CPU, DSP, Graphics, and MDP and includes a programmable function graphics pipeline.

And, so, I summarized that an enhanced GPU, in our chip, has a normal clocking speed of around 200 MHz, and it can be overclocked. How this is done, and all the other stuff, the developers might help you. And, if its safe... I also read that overclocking a little wouldn't harm. So, I guess it's safe.
Anyways, the Pros are that you would get a little extra fps, so you could "expect" a little improvement in gaming and video playback.
The Cons... Well, anyone using an overclocked GPU for long might know.

When overclocked the textures are rendered little quicker than normal clocking. It won't double the frame rate as some guy doubted. Look at the details of our CPU and gpu.

Hello
Will the sensation be better for playing games than the SGS 2, which needs games to be updated before they can play on the mali400? I hoping apps and games don't have to be recoded/reprogrammed to work on the adreno 220, if they work/play fine on the adreno 205?
Thanks
Ian
Not 100% sure but I think the problem with the SGS2 is that the Mali400 GPU doesn't support any form of texture compression. So any games that use texture compression needs to be recompiled and have the textures modified.
The Sensation should not have the same problem since the adreno 220 is just the next gen of the 205 and should be backward compatible.

Any new benchmarks comparing ADRENO 220 with MAli 400
i've seen a benchmark for an overclocked CPU with ADRENO 220 (clocked at 1.5 GHz). This does not give a good comparison as the real life sensation will be clocked at 1.2 GHz
Also any new overall benchmarks for the sensation, the old ones scored horrible 1200 pts. People are saying this is because the preliminary firmware is using only one core, but they did not post any reference proving their claim

What you're saying is not entirely true.
The 1.5 GHz is the chip's default speed (check Qualcomm's website) - the benchmark was of the Qualcomm development unit (MDP). The Sensation uses an underclock probably to reserve battery life.
Keep in mind, and I'm basing it entirely on tidbits I hear here and there on this forum and on tech blogs, that Qualcomm CPUs tend to get higher overclock speeds than the competition (or at least those who do it make more noise ).
As for the early benchmark - I was able to play with a similar device in question, software version 0.50.something, and yes - it was horrid. I ran Neocore just for laughs and it got 5 FPS. Later on I had a few minutes with one running 1.05 (not the final 1.20 that was leaked) and Neocore got 59.9. Wish I could upload a screenshot, but if I did I'd probably get fired (it has the confidential watermark with the serial number on it, which could than trace it directly to me).
Do take the above with a grain of salt - this is the internet and at the moment I have no way to give solid proof that what I said is true - you can just take my word for it (which if you're smart - you won't).
I will say this though - I have already pre-ordered one.
I think the Qualcomm cpus are the most efficent by far. My dhd runs undervolted all the way up to 1.2ghz and overvolts upto 1.6ghz, we have a stable 2ghz kernel atm too, my phone has never felt warm or hot. So it wouldn't surprise me if it was natural running at 1.5ghz.

i can't get scores like GS2 (stockROM) or better than him !!
If I'm not mistaken, the Areno 220 can push 1080p stereoscopic 3D.
The question is whether the manufacturers wrote drivers to help with the hardware acceleration, which is what Samsung did with the Exynos-Mali400. =)

Hi guys.
I wanted to ask you something, because in our sl i9003 is the maximum possible overclock 1300 mhz?
The Artex-A8 processor is not it?
It should be a very powerful processor, but even though I've always overclocchi various lag to 1.3, with any rom.
And my device has no flaws ..
So, back to the main question .. because the maximum overclock is only 1.3?
Now I'm using the rom with the look dell's3 and formatted EXT4 but is slow and full of lag .. Help!
Thanks.
I'm wrong or sI9000 can be overclocked more with the same cpu?

Well, you can easly push your phone at 1500MHz (BCK kernel feature: Evolved sysfs interface for variable overclock or underclock), but the phone is not usable. I tried once to slowly change the frequency to see my limit and @1400MHz the phone became unusable.
Other than being unstable because, quoting XDA_Bam, "Anything more than 10% higher than the highest stock frequency is likely to be unstable", I think the voltage set for the 5th OPP is too low for anything higher than 1300MHz (maybe I'm wrong).
Proof? here.
Actually, this is "fake". To take this screenshot I had first disabled the 5th OPP, then I changed its frequency so that CPU Spy showed 1500MHz even though I wasn't really using it. The time spent at that frequency was actually the time the CPU spent at 1200MHz before I had disabled the 5th OPP
I did that to show you that it's actually possible to (easly) change the max frequency to anything higher 1380MHz.
EDIT:
And BTW devs are continuosly improving this device, we were first limited to 1100MHz, now some phones are stable at 1300MHz. Remember that our cousing (I9000) is older and has a huge community.
EDIT 2:
"I'm wrong or sI9000 can be overclocked more with the same cpu?" => "I'm wrong or sI9000 can be overclocked more with a totally different cpu?"

You are wrong: the CPUs are different
i9003 has TI OMAP 3630 1GHz and i9000 has Samsung S5PC110 1GHz (code-named "Hummingbird")
Cortex A8 is just instructions and specifications for CPU. It's like DX10 for GPU. You can say Nvidia XXX card supports DX10 and AMD YYY supports it, why clocks for these cards and overclock potential are different?
I think the cpu of the i9000 is wors then the from i9003 so why is the i9000 overclocked to 50% and in our is it only 35%?
Cuold we not work on an overclock like 1.45 ghz for our phone ? Would it be unstable or is it because we need developers that can make it stable?

But can anybody tell me that whats the use of such higher OC (1.45ghz) when u can do same stuffs smoothly on 1.2 ghz easily??? Also OC looks very attractive feature but in my opinioin its a deadly battery killer feature. OC upto 1.35 ghz is more than sufficient (I am satisfied with 1ghz max with superb performance & good battery backup).
Instead of wasting time on overclocking developers should work on overclocking gpu, kernel 3.0 or video codec, video recording in cm7, cm9, miui, aosp roms. Because for now thats a big problem for our phone.

I am with you, we reached the limits of "smoothness" really (On stable roms, we shouldn't blame hardware when using buggy or incompletete roms or even stupid samsung roms.)

Remember when OCing just happened on our device? we were limited to 1080 Ghz, then to 1100 Ghz, then to 1200 Ghz/1300 Ghz, and now 1380 Ghz, devs will always figure out a way to squeeze more power and keep it stable, it needs time and effort.
The Galaxy S has a different CPU (That has lower OC potential then ours theoretically if i remember correctly) but has a bigger number of developers, it was released in 2010, our device was released in 2011 so it is kinda new.

Yes of cours but some developers can't fix this bugs.. But maybe they are able to overclock the phone (like uc team) and i think it's not a battery killer..

Remember guys, even if you OC the CPU, there will always be the weight of our outdated GPU dragging us down. Even if we OC to 1.45Ghz, you will always experience little bits of lag due to our PowerVR530. If I compare my friend's stock I9000 (No Mods, No Root, No OC:1Ghz) to my I9003 (with OC 1.38Ghz). My friend's I9000 will always be smoother due to both an advanced CPU and GPU.

does anyone know if setting the CPU SPEED to 1.5 GHz is dangerous while the SENSATION XL has the same chipset as the desire s has (Qualcomm Snapdragon MS8255) and the SENSATION XL's CPU speed is set to 1.5GHz .
sensation has msm8260 (dual core 1.2-1.5 GHz and adreno 220)
Sensation XL indeed has MSM8255.
Just like in PCs, chipsets in phones are binned not only by their type, but also by their target frequency. You don't go overclocking Core2Duo 1.8 GHz to 2.4 GHz because it's "the same CPU", right? Because it isn't the same CPU. The same applies here.
אז זה מסוכן או לא ?
English, please.
Answer - would you run the CPU on your computer at 1.5x the speed it was made to run, because there's CPU with the same name (i3/i5/i7/whatever) that runs at 1.5x the speed?
The same answer applies to your phone.
I expect people to be able to make minimal logic work with their own brains rather than just answering "yes/no". I think that this way people actually understand more than what they've asked for.
i guessed that was the answer but just wanted to be sure...
thanks anyway !

No it won't. It depends on the specific part, and few parts run stock 1.5 GHz without stability issues surfacing / burning out very fast (if overvolted).
If you really want - you can try it on T-Mobile G2, that has MSM8255 of the earliest bin, with stock at 800MHz. Good luck, don't forget to write how did you like a phone as a toaster.
I suggest refraining from bad advice, especially when it's in the forum and it's not your phone you're talking about. You can burn your phones as much as you like, but don't go around suggesting it to others. Just let me understand something: you have stock non-rooted ICS and have no idea about such basics as which guide to use to downgrade, but you allow yourself posting about chipset frequencies?
so which speed can i overclock to that shouldn't turn my device into a toaster ?

Hello everyone! With the launch of redmi note 5 pro and snapdragon 636 we have now a budget king. We know that 636 is based on 660 with reduced clocks for better efficiency , cpu cores being the same.What we don't know for sure is what gpu the 636 is using. We've been lead to believe that snapdragon 636 is using adreno 509 wich is a slight improvement over adreno 508 on snapdragon 630. Based on this article http://kyokojap.myweb.hinet.net/gpu_gflops/ we know that adreno 506 and 508 is the same core , and adreno 510 and 512 is the same core with the latter being on a node shrink to 14nm from 28nm.
So adreno 506 at 600mhz has 120 gflops , adreno 508 at 800mhz has 160gflops, adreno 510 (28nm) at 600mhz has 180gflops and adreno 512 (14nm) at 800mhz has 240gflops..
Adreno 509 is supposed to have a bump of 10% improvement over adreno 508 wich is around 160gflops. This means adreno 509 should be around the mark of 175gflops, right between the adreno 508 and adreno 510. If adreno 509 is the same core as adreno 506 & and 508 that means adreno 509 needs al least + 10% on the clocks. 800mhz + 10% => goes to ~900mhz for adreno 509. Not impossible but not likely because don't forget snapdragon636 is meant to be very efficient and the increased consumption cuased by the delta of perf/clocks at 900mhz is very high. So taking the assumption that adreno 509 is the same core as 510 and 512 , for it to be around 175gflops it needs to be underclocked at around 550mhz. A 550mhz clock would need a lot less power then a smaller gpu core (506) but at a higher clock ~~900mhz.
Adreno 509 being the same core as 510 and 512 would be very beneficial to us ,making the snapdragon 636 a very friendly overclocker both on cpu cores and gpu cores.
The problem with this theory is : I don't have proof. I don't have a redmi note 5 pro ( it's not yet released globally) and there is a lack of information based on this gpu's on internet.
We need someone with the phone , time and willing to figure it out at what clock adreno 509 operates. From there we can see on wich gpu core adreno 509 is really based.
Any news about this? On wikipedia there is some more information, but don't know if these are true. https://en.wikipedia.org/wiki/Adreno
Adreno 509, 510 and 512 all have 128 ALUs.
Adreno 509: 720mhz and 14nm
Adreno 510: 600mhz and 28nm
Adreno 512: 850mhz and 14nm
So if these information are true, the Adreno 509 should be faster than the Adreno 510 + less power hungry because of 14nm.
Can anyone confirm this?^^

However, my Redmi Note 5' Adreno 509 only gets 430Mhz under full load, so I think it's just a downclock version of Adreno 512. The performance of 509 is even better than 510, and barely produce any heat.

That's interesting. I just searched on YouTube for some performance videos, on Antutu the phone has a SD636 and an Adreno 512, so it could be really a downclocked version. I guess we need more information^^

if so, in the future it will be overclock adreno 509 to level 512
Did we get any development on overclocking the SD636 adreno 509 to SD660 adreno 512 levels?

Unfortunately, not yet. Some say that it's impossible to overclock but I dunno why..probably some higher level sources are locked or maybe some alu's are hardlocked is my guess. Does anyone here have an idea about it?
660 is a overclocked 636.

We nid proper frequency_table to do this, some kernel using source from 660 and bump CPU clock to 2.2Ghz for real, but not for the GPU, I hope someone could bring a new frequency_table for adreno 509 from scratch.. cuz its happen on sd435 just like simpleKernel by Luiz on Redmi 4x..

Wow, I see some interesting changelogs' on that thread for redmi4x
"Overclocked BIG to 1.49GHz and LITTLE to 1.209GHz using hardware unlocks thanks to @TecnoTailsPlays for working together to do this;
-> Overclocked GPU to 610MHz again, working together with @TecnoTailsPlays (https://forum.xda-developers.com/member.php?u=6821509);"
Would be nice if some devs like him can look at the 509's frequency table too.. The performance increase could be next level!

I tried his kernel with 675Mhz gpu clock and its awesome, it can run pubg with medium setup, the only issue is battery but I don't really care cuz higher performance = higher battery drain and its normal, I hope someone like them bring hardware unlock for our chipset,

Actually its the opposite. 636 is a underclocked 660

Resume what you guys want, I maybe take a look if there's a source for me to access
(I'm TecnoTailsPlays, that was my old name here in XDA lol)

Thanks dude!
The goal is to overclock the SD363 to match the SD660. Most importantly the GPU! The two chips perform basically the same CPU-wise, but in graphics the 660 is 30-40% more powerful, simply because it is clocked higher.

Thanks man, that'd be huge! I'm ready to donate too if necessary :angel:
Yeah if someone could make the GPU clocks like Adreno 512, it would be less painful to watch the Redmi note 7 and its SD660 XD
But anyway, SD636 to SD660 kernels exist for our whyred, its just a matter of getting that adreno 512. Another info is that our GPU gets 21k antutu score and 512 gets 30k. Not important but definitely a nice bump

Exactely!
The 636 is already a MASSIVE upgrade from the 625, specially gpu-wise (about 60%) and gettin that extra 30-40% would be magical.
But, would that stress the GPU and cpu? I have senn people talking with worry about that. And I noticed that there were many kernels with oc(I think most of custom kernels for whyred started with oc) but now I think that the only one left is kangaroo. All the others removed oc and ov. Does this mean something?
