I just saw the specs of galaxy ace.
Same adreno 200 gpu as our's and the same processor msm7227 but clocked at 800 Mhz....wtf?
I couldnt overclock my phone to a stable 806 ever
Can anyone make any comments please??
take a look

Kernel matters rolleys.
Sent from my LG-P500 using XDA Premium App
Yes, Its due to kernel only. And not to worry so mush. What FK has given us till now you can use @ 768, It's not bad at all.
lol binodray, u know about android or ur just acting like u know??
we cant overclock because the msm7227 in our device is connected to cheap cables and busses and probably cheap ahb or something...
thats y some people are able to overclock to 806 and some people are not able to...
No dear I don’t know anything.
On a short note
The MSM7227 is ARM 11 family 32bit Qualcomm MSM7225 processor. This series seems to run PLL2 at 1200MHz, which is why they are capable of running at 600MHz. (1200/2 binary thing).
what is over clocking?
Over clocking typically refers to running a CPU at a clock speed higher than that for which it was originally designed. And the kernel is told that it is being run at a higher speed (In realty it’s not).
Why phone crash?
When phone generate very high voltage due to increased clock speed we have kernel panic in result.
How we solve this?
As far as I know if dev can alter UV table in kernel we can have processor with 1728 which is 864. This means there could be one kernel supporting OC frequencies up to 1728Mhz (lets say 1728,1600,1500,1400,1300,1200,1120), and user could choose which ones he wants to use (eg 1400 and 1120, disabling the rest).
Hope this will make you clear why we need kernel and why OC is based on kernel codes.
just my observation: Quadrant run for touchpad only gives score of around 2400... my nook color with 1.3ghz single core gives score of over 2600 all the time!!! i looked into the device info, it seems like it only using 1 core!!! does cm7 only recognizing one core??? what r ur guys thought??? is there a fix for it or any kernels that utilize both cores of touchpad!!!
The Quadrant results on the TP are skewed because the GPU code has not yet been implemented (or optimized) which primarily affects the FPS section (looks like is is only doing about 4 frames per second) where all the other graphics demos (especially the planet one) do 20-60 frames per second which is a 300%-600% improvement over the Nook Color running 1.2GHz.
I would be interested in other benchmarks that are not dependent on the GPU code.
try using Antutu - free from market
it separates the scores according to each test
(also shows total)
i got around 5000 - OC 1.7 ghz
Maybe it is because we are running an un-optimized alpha build...Don't worry about synthetic benchmarks anyway.
Both cores are already being used, what is your processor clocked too?
I'm completely aware benchmarks don't really mean much, but for curiosities sake, out of 3 runs, I averaged 3228 in quadrant. I am overclocked to 1782mhz ondemand.
I suggest you run SunSpider also.
Hi! I have problem with perseus Kernel If I overclock cpu a little bit, All the same the problem (If I start play game some time it will restart), it does not matter how much overclocked. I tested 1.7Ghz clock and test it For 1375mv, 1400mv, 1425mv, and it's not effective and between a perseus rom freezes lock screen and I have to restart it :S, siyah kernel will not let me even overclock more than 1.5GHz can someone help me with this problem :laugh:, I love overclocking :silly:
SiyahKernel S3 v1.5 CPU over/underclock: 100-1800MHz 18-steps , GPU over/underclock: 54-800MHz ,Perfect to play , i have been using for a long time and i had never any problems ........

Okay But, why I'm not able to overclock 1.8GhZ its show me 200-1.5GhZ I tried overclock stweaks, cpu master, set cpu, and Foxhound extras but not help I try flash siyah again If that help.. Block story max settings eat really MUCH performance
I'm not even able hit over the 1.5GhZ and it show me 25-1.5GhZ (((
Anyone?
Anyone know what I do wrong if I'm not able hit 1.8GhZ?
yes,, your cpu isn't up to it, simple. With overclocking make small steps, note what you are doing, experiment with voltages, but all chips are different so experimentation is the only way, along with lots of reading and learning, skill aided by searching

okay But why this perseus give me overclock more than 1.5GhZ But Perseus is so buggy :S and I can normally overclock Gpu with siyah kernel but If I run test I am not note difference, 1 better fps for 700MhZ GPU Clock My Phone is so strange

you have to understand the fact that the kernel is in alpha stage, so if you dont know what you are doing you shouldnt have flashed it. and also all chips are not capable of handling higher frequency, 1.6 ghz should be asafe bet for all processors..
700mhz in siyah makes a big impact depending on the benchmark you run.. check the thrread in my sig for more info.
Thanks all for posts! I figured it out, I give more juice for all these steps for perseus alpha And not anymore reboots. 1.8 GhZ 1450mv 1.7GhZ 1400mv, 1.6GhZ 1350mV, 1.5GhZ 1300mV, I run now 1.7GhZ for dual core mode, I'll try soon run my phone quad core mode . But I can't overclock my gpu with perseus and siyah rom doesn't give me overclock more than 1.5ghZ DD so strange Ps: 1.7 GhZ Dual core My Cpu score is 8123 and memory 5538 on quandrant benchmark.
Edit: If my phone a little bit overheat it reboot same thing is 1.6GhZ, 1.7GhZ, 1.8GhZ. 1.6GhZ I run stability test about 1-2min and it reboot, Battery About 41 degrees Celsius :S
Why in the name of all that is holy would you overclock your CPU, and then run it in dual core mode??
You would be better off leaving it at 1.4ghz in quad core mode.
That seems pointless.

I make video today
Sent from my GT-I9300 using xda app-developers app
http://www.youtube.com/watch?v=glPp2ORTvFo&feature=youtu.be Sorry for poor video my video editing software doesn't working But If I run test about 1 min device reboot My video will not be saved if it shuts down so I had to stop Stability Test before a turn off.
I will do later in the evening siyah kernel video for overclocking problem
Hi everybody.
It would be nice if someone could make Kernel/Rom with possible GPU overclock.
By my knowledge in Xperia P is Mali-400MP with 1 (i find somewhere 2) core fragment with default speed 200Mhz.
In older SGS2 there is Mali-400MP4 on stock 267Mhz.
Is there a way for safe overclock Mali GPU in Xperia P to 267Mhz or maybe 240Mhz?
Best regards
no, not yet, and maybe never.
it will only gives problems (battery drains much faster, phones become very hot etc.)
NovaThor chips are designed for low power consumption, also overclocking the Cpu the heat produced still low.
I think that the biggest problem is the driver of chip and its documentation
mali 400 stock Frequency min 240 max 395. why give problems (except for battery )

it will give problems for sure but on some heavy games our phones needs gpu overclock
Overclock only turn your phone to heater and energy eater, no to lamborgini
PS:sry for my bad english
If not overclock, atleast governor control? And I/O too if thats possible?
Is this possible atleast?

max overclock on my s2's gpu is 520mhz (wid custom kernel) bt it requires 1350mV .. sufficient enough to make a fried omlet...
being an ex xu user.. i have found no game (atleast among what i play) which ran properly on s2 bt not on xu.. extra cores gives better benchmarks real life perfomance is games is almost similar...
hi all,
is there a way to undervolt and or OC the CPU and GPU?
I remember reading a article a month ago about a GPU OC, but somehow that's it. No way to download the mentioned app etc.
Is there anything for the Mi 10 / SD 865?
Snapdragons don't overclock because they're not underclocked.

According to this news oage, we still have some potential left in our SD865
Xiaomi Mi 10 Overclocking Has Improved Significantly
he game performance has also been improved in addition to the higher running scores of the overclocked Snapdragon 865 models.
www.igeekphone.com
here is even a XDA link to another phone without any links to the app itself...
Abandoned
abandoned.
forum.xda-developers.com
so there is a way to OC and UV the SD865
That isn't what it appears to be to me. It appears to be an ongoing project to oc/uv the snapdragon processor and gpu and so far all they've done is managed to change the ram clockspeed. The pros of undervolting the ram is less heat but the cons is bottlenecking under load because ram uses voltage in correlation to clockspeed. If you overvolt the ram it produces more heat, processes more data but stability goes out of the window completely. This is NOT CPU/GPU core clocking and won't have any effect on the cores whatsoever, only data throughput.
I'll stand by my word coming from HTC to Xiaomi, both snapdragon phones, you can't overclock a snapdragon because they're not underclocked. It has been that way for a long time. What they advertise the chip as capable of is what the chip is capable of as by design and will actually be that way in the field.
If you want proof just take a browse around the later HTC phones and you won't see anything about core clocking, probably not ram volting either..

No offense, but have you read any of the two links I posted?
They literally explain, that they changed/overclocked the GPU frequency to 865mhz
stock frequency should be 587mhz.
They did overclock the GPU.
They even proved it by showing some benchmarks.. and compared it to the SD888
And this is the first time I read, that SDs are not overclockable...
865mhz is the bus and ram frequency. The cores are in the ghz.
All that has been achieved is a higher throughput and that equates to more heat and more used power. This stuff is well researched.
I honestly dont get, where you getting the RAM OC thing.
They do not use ddr7 or ddr8 on a mobile SoC, because the tech isnt there yet...
If you search for the Andreno 650 GPU you will see its specs that it is clocked at 587mhz (and not the Ram).
They are of course adjusting the ram timings too, but the xda links tells the following:
"2. edit your settings in the 3 tables. (start with adding the extra step form 865+ to 865)
3. press "Save GPU Freq Table" after editing any page, before you move to another."
If you want to stay with your resolution on this topic, it is fine.
I just want to know where we can get the KonaBess app, because google only links me to chinese pages and somehow this topic isnt as popular as I thought.
Not 100% sure if this link is allowed.... https://github.com/xzr467706992/KonaBess/releases/tag/v0.12
Scroll down to assets and its in there.

Just a heads up, not all snapdragons are created equally. That said, there is definitely performance left to gain via OC the adreno 650 gpu of the 865. I'm currently running a massive 930mhz on my adreno 650 and a very small cpu OC and with that, it blows the 865+ away in benchmarking and trades wins with a stock SD 888 with CPU and GPU bench scores. Any OC'ing you do I highly recommend doing a stress test before thinking you're stable.

Thanks for the heads up, I am already aware of the "silicon lottery".
I am amazed how much juice is still left in the SD865, that OCd it can even beat the 888 and is more consistent.
Do you use any App to monitor your temps and how did you OC your CPU? Afaik KonaBess only allows GPU oc?

Hi, I can't seem to find any tutorial online on how to overclock. Could you help me out ? I am gonna order a Black Shark 4 with the Snpadragon 870 soon, which is the best cherrypicked chip along the same chipset as the 865, which means that it's more likely to be a silicon lottery win... Can we get in touch on Discord ? My username is Meli #6318.
please guide me to modify the necessary things to overclock (kernel, file...)
anyway i still want to overclock it and gpu

How did you oc the cpu ? and is it possible to oc the gpu of the sd870 which is also the adreno650 but I’ve heard that it’s locked by Qualcomm trust zone , is it just a problem with sd870 or even 888 and 8 gen 1 ? Thanks in advance
