>DD redmi note 7 pro can be overclocked

somebody tried it, screen was flickering and unresponsive.

I would be really curious but why would you want to use such a frequency? For some now "well known" game? Why do you think they improve graphics performance? Well I your reason I don't know him, but I know that even if and I say if it were possible it would be useless and there would be no benefit (or maybe someone would but at the expense of the rest of the device) Of course there are kernels that increase the processor clock (at your own risk of course) but the CPU and GPU are not the same and above all it is a smartphone not a PC ...

Overclock?

I'm a speed freak. I know our CPUs are at 400mhz already, but what about pushing that further? Are there any utilities out there that can do this?
None work with the Qualcomm processor since it's dual core. It'll probably be next to impossible since the other core has to be overclocked as well and it's part of the phone side, which may screw things up. The Mogul has the same exact one.

I would say that if you were in the fancy of a nice, pretty, expensive paperweight, go ahead and try to overclock your Touch.
I've overclocked tons of PPCs... what you get you in speed increases is a decrease in battery life. IMHO not work the give/take.
dharvey thanks for the useless comment. jessiethe3rd maybe some people are willing to give battery life for speed. It would be nice if people were less willing to cut down someone for what they want, and maybe answer there question instead, no opinion needed.
That's kind of why I've left this thread. No one seems to want to give helpful advice/info. They are all about telling me what i'm doing wrong.
Comes with being on the internet, though.
Please forgive my previous comment. I was in a crappy mood and I really didn't care who I offended when I posted that comment.
Unfortunately there is no true way to overclock the Touch thanks to the dual core processor. One half of the processor is used for the OS, while the other half is geared mostly for the phone features. In order to overclock one half, you would have to overclock the other as well and this could potentially put your CDMA radio out of commission. If you only decided to overclock one hald of the Processor, you would probably fry your device and I know you don't want that. I don't want that for you either.

Speed of snapdragon cpu

Hello to everybody.
I read somewhere that the cpu on hd2 is set slower than the maximum.
Is it true? there's a possibility to benchmark it or not?
If true I suppose it is necessary to use cooked roms (when available) to set it to 1 GHz and so obtain the top performance...
I am asking it because I am a newbie of the forum, of windows mobile and smartphone in general...
Thanks a lot.
don't believe everything that you read.
AFAIK there's no benchmark that supports snapdragon, so how can it possibly say what the processor is, never mind what speed it runs at?
***EDIT*** I speak too soon..
looks like sktools does support snapdragon in it's benchmark in the latest version:
Integer test..
I got 812.05
theres a HTC TOUCH HD2 WM6.5
Qualcomm (R) QSD8258B 1GHZ
as one of the comparison devices..
it scores 813.45
DAMN MY HD2 is slow ****
**** ROFL as if
to be exact, it totally doesn`t matter for me, but>
i read somewhere, that snapdragon is going to be (or it is) used in some subnotebooks or whatever are they calling... and for PDA`s is underclocked from 1,3 GHz to 1024 MHz... don`t know if it is true...
the CPU is not "underclocked"
but the problem is that inbuild graphic accelerator is not working, HTC did not supply drivers for some reason(some say legal issues)
i really dont get it.. why they build something in this mobile phone, when they dont want to use it.. are they $%#@!!**%# or what i just hope, some "masterhacker" will make a driver for this baby and we will have a real "unleashed beast"

o-h-m-y-g-o-d... really?so I have the confirm that in HTC are doing a really bad job... I mean:we have the Ferrari but we use GPL instead of gasoline?
Wow another "HTC didn't supply the drivers" BULL**** thread! Can you stop spreading lies please?
Mods should closes this.
Bad drivers
It would not surprise me if the drivers were giving lower performance than possible.
This really did happen with the Touch Cruise which was painfully slow,
until Guys here developed some very good drivers, which made the TC perform at much higher speeds than originally.
Good news is that the same guys, Chainfire & Neo are working on improved drivers for graphics & processor.

Is it true that LEO's CPU is limited to 712MHz?

Hello All
I've just found this line in Eugenia's ROM thread:
"*- CPU scales to a maximum of 1GHz instead of 712MHz"
Is it true that the CPU is limited to 712MHz in the shipping ROMs?
If Yes this may explain the lower performance compared to ACER F1 and Toshiba TG01
I was wondering this too
This could do with some deeper investigation by the experts amongst us...
If this is true, I can imagine the HD2 FLYING when we have custom ROMs!
Mine is pretty damn fast with ROM 1.48!
it's certainly a very bold claim, without any support to it..
I would like to see what hard evidence there is to support it,
as if it's true, then HTC have been illegally advertising the HD2 as 1ghz capable device..

Suppose it is so, they did deliver a 1Ghz device, it's just limited for some reasons. First to my mind is battery life. Nevertheless, investigation is required and I hope kholk can clear some things for us since the seed was found in his thread.

My point exectly!
The only evidence we have for now is the line I quoted from Eugenia's soon to be released WM 6.5.3 ROM
But I've been thinking for a long time that the lower performance of the HD2 compared to other Snapdragon devices is due to some form of power management lowering the CPU frequence!

"HD2 as 1ghz capable"', does not mean it is running at 1GHZ but it could run at that speed, altough implied, but indeed it would be a misleading advert campaign
but i would like some proof too

The way its advertised means it would have to actually run at 1GHz, not just be a 1GHz model limited to less.
Unless its just a rubbish claim then i assume the ROM developer means limited to 712Mhz in certain situations, which might be for perfectly good reasons.

I don't agree: a software underclocked 1GHz CPU is still a 1GHz CPU. The chip is the same.
Not when the phone claims its a 1GHz CPU, which it does. The speed is not the name, its a physical attribute of the CPU that only exists if its actually running at that speed. This has been covered by EU law before, HTC cannot legally sell a phone running a CPU capable of 1GHz and claim its 1GHz if it never reaches that speed.
I suspect this ROM will just force full throttle all the time, which can only be bad for the battery life, but since we cannot flash it yet we dont know the effects, or if it even works at all.
HTC is advertising the HD2 machine as "1GHz capable device", but not as "1GHz device" that it's different.
It's barely legal.
Anyway, there IS evidence. And you can see it using TCPMP and doing some tests using the device's CPU
On this purpose, we've been talked on the xda-devs IRC channel about that, and I'm saying what I'm saying ONLY based on my tests: try to run TCPMP and see the CPU freq that it's reporting: 396-412MHz!
Use a program that is HEAVY on CPU load and run it in background (make sure that it won't close and that it will continue its work even in background) then see che CPU freq in TCPMP: you'll reach a maximum of 712MHz.
Another evidence of this statement is the performance of other SnapDragon machines like the Toshiba TG01.
P.S.: I think that the HTC HD2 will reach its 1024MHz frequency only when playing with the GLES2.0 Qualcomm test game, ELECTOPIA.
Electopia takes the device in EXCLUSIVE MODE, so it's possible that its frequency will be raised to 1GHz.
Its also quite possible that the CPU speed reporting programs do not support the snapdragon properly and report the wrong information.
The phone itself says the CPU speed is 1GHz in the phone hardware properties, this is a claim of speed, not name or theoretical capabilities.
So we're talking about dynamic freq adjustment on the go depending on processing power needed, similar to AMD's Cool and Quiet concept?

doesn't work like that does it though? they advertise the device running at 1ghz and it doesn't then that's false advertising..
If (and I doubt looking at the benchmarks) it ran at 700 ish mhz (maximum) then they should have advertised it as such
they don't mention "1ghz capable" here.. They clearly state its CPU processor Speed (not theoritical or otherwise) as
CPU Processing Speed
1GHz Snapdragon™ processor
http://www.htc.com/uk/product/hd2/specification.html
and Overview
HTC HD2 delivers an experience your senses have been waiting for. The unprecedented 4.3-inch pixel-packed display is stunning. The world’s first capacitive touch technology on a Windows® phone along with 1 GHz processing power ensure a smooth and lightning-fast response to the lightest touch of your finger
It's like stating it has a 4.3 inch screen and then actually finding it was 3.3 inches because the edge was covered in protective cover..
http://www.htc.com/uk/product/hd2/overview.html
not saying this is true at all.. we all know cpus have been scaling for a while, and the HD2 certainly scores high enough in integer testing..
but if that's what it is then they are likely to be in trouble over this.
anyway Kolhk you claim to have it able to scale up, how have you done that?
this way we can try to replicate it

If it reports the frequencies of other snapdragon devices correctly it shouldn't be an issue. And to they can't advertise the device as having a 1Ghz processor unless it runs at that speed(would it be ok for amd and intel to sell 4Ghz chips if they actually run at 2+Ghz, just because that would be their theoretical maximum?). The processor is probably, as mentioned earlier, just scaling back when it isn't used to 100%.

...and I bet if there's a text on the chip inside the device, it states the same on it. As far as I see things, HTC has a device with a 1G Snapdragon CPU which I bought. CPU inside, as described.

Actually AMD sells processors like this: AMD Athlon 64 3000+ which actually runs at 1800.
A CPU speed programs needs to support the way the CPU is actually controlled, not just the CPU, so basically the clock generator as well. If The HD2 uses a different method from the F1 or TG-01 then the program wont work.

OMg WTF!!!

Hm? What you mean... Cpu Clock Speed 553Mhz...
Hahaha, that's funny.
It might be because pocket dos doesn't recognize something and it displays a default value. Maybe it doesn't know about the new hardware we have in the HD2. Don't know for sure, its just a guess.
There has been talk in at least one other thread that the CPU only runs as fast as it needs to for the workload it has. This reduces heat generation and power use.
If this is indeed the case then this could explain your outcome.
and other from Sktools
From what I've read in other threads, this is because there isn't any software (currently) that's capable of calculating the speed of the Snapdragon processor.
Don't know how true it is, but I can tell you for a fact that this phone is running faster than that. I know that after having a HD, running a Leo ROM on it. It was VERY slow, compared to the lovely, fluid HD2.

another junk thread and waste of time! Feel the phone, it is obviously telling you it is bloody fast, no need digging data to proof the actual speed it has!

All aboiut OVERCLOCKING thread.

I wonder if we really "need" to overclock this beastly CPU of ours? Hell, even if i underclock to 1Ghz, most task if not all are done fast, really fast. Talking about games? Modern FPS games are driven by both CPU and GPU and thus doesnt require much of horsepower of the CPU. Im confuse why numbers of people here are crying "why they are not stable @ 1.8Ghz"? ... Even if you set it @ 1.8Ghz max, our phone will barely reach this clockspeed because other cores will kick-in in less than maximum speed of the primary core (if im right?) ... Is it just for Benchmark figures? Good figures doesnt equates to good performance and we all know that... Can you really sacrifice "Stability" for the sake of some "Ego-driven faaassssstttt BM"?
I swear, some people are just so dense. Why don't we all drive Honda civics? Do we really need a car with over 200hp and can top out at 150mph when most speed limits are 65mph? Why do we bother eating at expensive restaurants when we could save a ton and eat at mcdonalds? People have preferences...it's what makes the world go 'round. If people want to overclock, let them have it.

Haha good one.
I drive a v8 6.0L lumina SS, my pc is o/c'd from 2.6Ghz to 3.8Ghz Quad core, ram is overclocked to 1700mhz, have crossfired 2 5870s and tested them at 900mhz, my SIII is overclocked to 1800mhz, my LG O3D is oc @ 1350mhz (1ghz original) I guess i like fast things Maybe the OP is just a laid back happy go lucky fella and if everyone is like him we would be all driving steam powered cars and flying in propeller planes
Ok, you got me Guys .. But what pissed me is that this people all points their finger to the Kernel or Dev when they have reboots and heat-ups which is obviously the effect of their Overclocking... i can remmber a post; "damn, why i cant reach 1.8Ghz without random reboot, please fix"...
I actually agree with the op personally and I have been developing on android for four years since the g1, I don't see the need to over clock this phone as it runs really well all of the time,I too had the optimus 3d and that definitely needed overclocking as that was so painstakingly sluggish without it. the only reason I would overclock is for benchmark results other than that its just another drain on the battery for no real world performance gain

you just can't fix ignorance. if someone doesn't understand the concept and risks of overclocking, let them figure it out. sometimes it irks me to encounter posts like that as well.

Off topic: Optimus3D ROM is one of the most poorly optimize in modern Android flagships... I too had one, running it with AOSP is buttery smooth but also have some compromises...
I am sure you are missing the main idea of overclocking. First of all people normally do it to achieve better results in benchmark. But more and more are starting to do it for better performance and so. Overclocking a phone is useful for the first mainly, I doubt that anyone would overclock their phone in order to play games with better fps for instance. The whole idea is bad, there is a large difference between a phone with minimal cooling and a big ass desktop with 50 fans. If we want our devices to last longer we needn't touch them to make them "faster".
When I can overclock to 1.6gh AND under volt to 50mv below the stock voltage for 1.4GHZ it's pretty much a no-brainer
