Is it just me, or don't tegra-optimized games benefit much from overclocking ?
I have Rogue-Kernel 1.3.1 (with GPU OC) running and can definitely say it's working nicely. (Antutu bench @ 1.6Ghz/ performance 7200+ points, @ 1.0Ghz = 5000+)
Playing Riptide or Shadow Gun, I don't really see much of a difference. Just underclocking to <= 400 Mhz produces lower framerates. Obviously these games are heavily GPU-dependant and don't really care about the CPU.
The Rogue-Kernel is overclocking the GPU as well (given you don't install the "N" Version). So is there a way to change settings for the GPU, or is it maybe linked to a "clock-network" like some other chipsets, or is it overclocked automatically - depending on the CPU-speed ?
thanks in advance ...
hm, so all you overclockers are oc-ing for benchmark numbers only

so, i am using the Fear Rom and with the OC karnel. i played around the max sittings to 1.4 and tried quadarant. amazing score of 4150. nice... but what will happen if i keep it at 1.4 ?
will it over heat the phone / burn the GPU/CPU when playing games for example ?
i understand the battery life will be shorter. but what other disdvantages ?

You could dmg ur cpu. But Tegra is known to run 1.8Ghz stable. So with 1.4 you should be good.

Oh!! Great 1.8Ghz but only 1.4Ghz is very drain my battery to much.
In the long run, your cpu might get affected but its shouldn't happen so soon.
That said, in my honest opinion, don't need to OC the chip.
The same OCing rules apply from the PC World. The same batch of chips have varying maximum OCing capabilities and thus different stabilities. Although you can stably run a chip at a higher clock, it will definitely shorten its life (Sometimes it could kill it in a year, sometimes beyond what we can measure.). Chip makers purposefully OC chips during tests to simulate the stress effects of using the chip over a long period of time (OCing that makes it seem like the chip is being used for months or years.). Nvidia sticks the Tegra at 1 GHz half because it's cheaper to do so (don't need to ensure higher clock rates which would mean a larger percentage of their chips won't last doing it.) and half because of marketing (At the time, no one has 1.2 GHz like we do now. From what I've seen, Tegra 2 can do 1.2 GHz easy.).
So what it comes down to is how long you plan on keeping the phone and how lucky you are. =)
Imo, in the interest of power savings (P = (V^2)/R), the gains of OCing having an exponentially worse effect on battery life.
imho theres currently no point in oc'ing the Tegra2 in Optimus at all.
Theres no real life benefit, only theoretical benefit when running benchmark apps for show off.
Theres not a single application or game out there today that require more processing power than what the Tegra delivers at 1ghz - and not a single one out there that will run any better or faster by oc'ing because the demand for processing power to run the application or game at its maximum capacity are allready met at 1ghz
Basically there are only negatives in terms of decreased battery and cpu life for nothing but a screenshot of a higher quadrant (or whatever) score
If at some time in the future you should run into a game that would not run smoothly unless the cpu are oc'ed then it would make sence to do so - but for now not.
The games available today either do run perfectly smooth at 1ghz or if they dont, then they dont because of poor programming or other factors and they would still run poorly even if the cpu are oc'ed
Actually there are real life benefits until you find a game which really lags when you run it. Meaning, you should leave it as it is until next year.
It may damage the CPU like what others say but since lower clocks are undervolt it might last as long as a non OC (Stock).
But it will kill the battery faster as you will have to charge more often due to the higher power draws.
I've just flashed emanoN v3, it has No-Frills CPU control app by default, I used this app to set my CPU like this: Max 710Mhz, Min 245Mhz, Governor performance, I/O scheduler deadline --> Apply on Boot.
But is it me or it doesn't make any work on my Galaxy mini? I still get lag on many games like when not overclocked!
should i use chain fire 3D?
[Sorry 4 my bad English ]
Try other governors and reset your phone after making changes.

I did, but
should I use chainfire3d instead of NO-Frills ?
Chainfire 3D is graphics tool for better optimization of games and other 3D apps.
Did you check Apply on boot option?
as in my question: I checked Apply on boot option
If OC doesnt make any work on galaxymini, why did they add it in custom ROM 4 galaxymini?
Try other rom like CM 7.2 overclocking worked for me.
why doesn't the OC make any work on Noname ??!!
A tried over-clocking a couple of times but I really didn't feel the difference, except the battery drain, of course. Now-a-days, I don't even care to over-clock.
I am having my mini with cm7.1.0 music edition and overclocked it to 782 MHz and I find that in set CPU native benchmark I found that it took 900 micro second less when I clocked it to 782 MHz so I can say that Oct really works it also make my device run more smoothly its true that some games like angry birds lags yet after oc

maybe ur device has power enough to play many games that requires high-end hw, maybe not
but I wanna push my galaxy mini to play the effing awesome games just like the other high-end devices

OC can improve device's performance, but that improvement was identified by ur own experiences or measurement software?
that's right, I've got lag in angry birds even after OC
my phone is OCed at 782mhz and it's lag free everything works flawlessly...

Many games are tailored towards devices with 1Ghz processors and newer (including dualcore and advanced GPU's like the Tegra2 and Exynos chipsets). Don't expect the latest games to run reliably on a sub-800Mhz singlecore device.
Apps that require Chainfire3D are unlikely to work very well at all on the SGM as they're generally aimed at the higher-performance devices.
If you want to see the difference an overclock makes, then run an AnTuTu CPU benchmark before & after overclocking. If the figure doesn't change much (You should expect an increase roughly relative to the % of the overclock) then something isn't working correctly.
I can play Need For Speed Shift without any lag

yup! I just expect the Oc makes change that I can feel thru my own experiences! I dont want to see a good result on Antutu then THINK my device has better performance!!! U know what I mean?
btw, just looked ur signature, u r a serious guy, arent u? haha! It's a cooler way (that's what they thought) to write, why so serious
We are lucky because s5570 is equipted with gpu. Why dont you try using cm7.2 oc with 782 kernel. Plus a2sd and v6 supercharger.

Hi, Now I want to get performance and smooth running games. Right now I get 20-30FPS on GTA VC on JellyBAM rom. I want to undervolt GPU. Now is 400mhz at 1100mV it is safe to add more mV? Like +50 or +100? and do I feel any difference?
I am bit confused ,
There is only a difference of 200 MHz and a armv7 processor can handle much more than a armv6 processor.
Many games today releases for armv7 or for the phones with 1024MHz processors,
My x8 reaches a top of 806MHz,
As an example,
i played GTA 3 without sound,
with increment of 200MHz others can play even gta Vice city with HD.
I gonna be mad, whats wrong here,
Please someone elaborate!!!
Difference between these 2 types of processors is not just about CPUClock, arm7 processors also have a hidden memory called "cache memory" ,this memory is expensive & absolutely super-fast so CPU don't have to wait for data to transfer from RAM (slow compared to cache mem)
This cache memory in armv7 devices is about 1 megabytes, but in armv6 its just afew kilobytes
It's not just cache, CPU design in armv7 is different ,some games use special libs which is included in armv7 roms, etc,etc........

The differences between armv6-800 and armv7-1000 is NOT only the 200MHz.
The real difference is the processor design. The armv6 is older design (on x8 this is an arm1136 core), the armv7 is newer with more "knowledge". More complex instruction sets (the armv7 have special instructions what we not have) higher IPC (instructions per clocks), etc... Example: our x8 have an arm1136 core (possible to overclock to 800MHz), the xperia mini have scorpion core (similar to the popular cortex a9 design, but a little bit faster) what is 1GHz on default. But the scorpion core have newer float point unit (vfpv3 againt our vfp), have the armv7a addons in the instruction set, have the NEON extension (what is an audio/video proccessing accelerator), have the thumb-2 extensions (what is double fast than the old thumb-1) and finally: have newer GPU (adreno 205 against our adreno 200, what is theoretically have double computing speed).
So, if you compare the two phones, you can see: on paper the differences is small (400MHz (only 200 with oc) in cpu speed, near same gpu, same resolution), but with heavyweight apps (usually the hd games) the mini can be 2-3 times faster than our phone.
Hi N7 fellow users
i get MAX 2600 3D and 350 2D in antutu and quadrant though i'm all the time OC the GPU to 520mhz
is that normal ?? i'm running the latest Paranoid Android rom along the latest Franco kernel.
That is about what I get for 3D. If you go to the developer menu you can improve your 2D performance by checking the "Force GPU rendering" . For what it's worth my 2D for Quadrant went to about 1000 after the checking that option.

My htc one X was getting 39xx, 1k higher than my nexus
though they use nearly the same gpu.

quadrant does not measure gpu, it measures fps. and we are limited to 59fps no matter how much we overclock the gpu. use a benchmark like windmill, or basemark taiji, to test your gpu and what tweaking your gpu does. quadrant is an old, out of date benchmark.

i guess i have to forget about all this paranoia coming from the low benchmark scores since every game works xD
(except horn strangely runs about 25 fps it seems, even though i'm oced to 520mhz)
Low of diminishing returns, if you over clock it doesn't mean ull always get higher scores, after ur GPU gets heated up it start to show lower and lower scores.
GPU is stable @ 446 (beyond that when ever it gets heated up it will cause touch and other issues)
