Heya folks,
awhile ago, i installed batterystatus plugin and it reflected the device speed as 300MHz.
Yesterday, after installing sktools 3.0.74, i chanced upon the following while playing around.
System Info:
Processor core : SC32442-400MHz
Clock speed: 300
This bothered me .
Googled the net to find possible answers. And it seems that i'm not alone. Some others have found the processor to be "underclocked" at 300MHz, but all had assumed that it was probably the batterystatus plugin that was reflecting the clockspeed with errors.
My question is, it would be a mighty coincidence for both abovementioned apps to reflect the samsung processor as so. If it is indeed a Samsung 400Mhz proc that's been underclocked, does anyone know of a way to clock back to 400MHz.
have a hunch that this 300mhz is software limited. Can anyone shed some light on this?
It would be great *hint hint* if some guru could write a simple app to allow us to choose between 300 or 400 mhz or battery savings or full-on power modes.
Thanks.
From what I know .. it's actually a 300MHz proc that has been overclocked to 400MHz ...
On Hermes production devices the processor is Samsung SC32442A - 400MHz @1.5V
On Hermes preproduction devices the processor is Samsung SC32442 - 300MHz @1.35V
See the wiki hardware page for the samsung link with detailed information on the processor.

heya pof,
thanks for the pointers. However, i do not think that i have a preproduction model. my S/N HT631xxxx.
Could you shed some light on this. Thanks once again.

My Jasjam shows the same.
heya ppcnut and mlai,
in device information, mine shows the same as yours.
CPU: Samsung(R) 2442A
Speed: 400MHz
However, in both batterystatus and sktools system information,
the speed is reflected as 300MHz.
Hence i had thought that the device info was a static text file, and not actually reflecting the actual clockspeed of the device.
I think you are 100% right.
8125 300mhz w/battery status
I have an 8125 and Samsung(R) 2442A, 400mhz. I also have a reading of 300mhz with battery status. Does anyone actually have one that shows 400mhz as operating speed or is this the way it is?

you do not have an 8125 that reads 300 unless its broke.. do you maybe have a 8525?
has anyone done any benchmarks to show that the device is actually running higher than 300??? mine shows 400 in the device info as well.. and every app that i have used showed mine running at 300, i find this very odd...
Yes, I do have an 8525, just got it so I guess it was Freudian...sorry.

have others Replacement
CHT9000 CPU is Samsung SC32442
have anyone know others cpu can Replacement Samsung SC32442 ？
Battery Status reads my CPU speed as 400mhz on my 8525.
Here we go. I took a screen shot of my Today screen. Reading 400mhz as we speak.
I've got an I-mate Jasjam which also shows 400Mhz for clockspeed. Cheers...

No, there is no other replacement. Why dig up this old thread that does not pertain to your question?
Hi!
Is it possible to edit the CPU frequency of the Qualcomm 7200? When i had my HTC P4350 (Herald) I used an app that i THINK was called omaptool or something. It could downclock the CPU when not stressed and automatically overlock for certain apps say tcpmp.
Does this utility work with the Qualcomm CPU or is there an equivalent one?
Thanks
MS
Omaptool is for Omap processors like Qtek S200 or HTC Touch , and we have a Qualcomm processor.
For the moment , as far I know , there aren´t any software for this.

Just what i thought =( Well lets keep the thread alive and wait for better times..
The Toshiba TG01 has built-in cpu scaling which is nice to ensure maximum speed (Maybe why it beats HD2 in benchmarks?)
Does HD2 have this (I doubt it as its never been mentioned) and if not, could it be ported from TG01?
Thanks!
Bump? Is nobody interest in this?
CPU scaling doesn't ensure "maximum speed"... if there was no CPU scaling the processor would ALWAYS be running at maximum speed. Scaling slows the processor down to save power when it's not being used as heavily.
This kind of support is likely to be at hardware/OS level, so I'm sure it's going to be on the Leo.
Does neuROM not to something like that? Slows down the processor when the display is off etc.

These sort of things tend to be specific to certain OS/CPU combinations. What worked on the old Qualcomm chips probably won't work on the Snapdragon. Maybe it will, but if not it would have to be modified to work with the platform.
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.
The folks at the HTC Sensation/EVO 3D section extracted the Adreno 225 drivers from the HTC One S, as some of you may know that the Adreno 225 is the same as the Adreno 220 GPU but just have double the frequency! the frequency has nothing to do here if you ask, using these drivers gave them a HUGE performance boost with the STOCK frequency
as we know that the Mali 400 GPU at the SGSIII is clocked at 400mhz but even if you clocked your Mali 400 GPU in your Note (which has the same Resolution) you wont be able to reach that performance which tells me that its all about the drivers just like the Adreno 225
So can the Developers extract the Mali 400 Drivers from the SGSIII so we can use it on our phones?
This is not a question so i think it belongs to here not the Q/A section as its just a discussion if this is going to work or not!
Same driver, bigger screen = performance loss.
That is why Sammy set CPU 200 Mhz faster on Note over S2.
Screen has NOTHING to do with anything the Resolution does, which is the same in the SGSIII and the Note
Also that's why i said if you overclock the GPU to 400mhz you still wont reach that performance so it has to do with the Drivers
The note and SGSIII do indeed have different different screen resolutions, the Note being at 1280x800, while the SGSIII is at 1280x720. not much of a difference though, basically 16:10 vs 16:9, respectively. I believe the new Mali400 Drivers will be in the next ROM update anyway.

Well , if they are exactly the same just different clock speeds then I would think they should work indeed.
This is interesting and I certainly hope it does , not that at 400mhz or even less, the GPU is lacking but who does not like more performance for free?

Just check the replies to see the performance boost, This is the EXACT same situation as the Note and the SGSIII GPU
Wow, that's a good boost.

I think if the Note users can have that kind of boost on their phones that will eliminate ANY kind of lag in the UI and it i will be Amazingly smooth it will also give huge boost to the SGSII users
if this really happened and it does work, what about the battery-life... can be poorer i think
In theory, I see where you're going with this, and in theory it sounds plausible. However, something that I think has been overlooked is the process design of the new S3's chipset vs the ones found in the current generation S2/Note (45nm vs 32nm). It's entirely possible that the only reason why Samsung is able to run the Mali-400 at 400mhz is due to the fact that the 32nm process is just that much more efficient, such that you can safely run at 400mhz using the same power as you would running at 266mhz on the 45nm process.
I just get the feeling that trying to push the 45nm process up to 400mhz might simply melt the silicon (or at least gobble your battery life in one gulp!). Call me defeatist if you have to, but I remain skeptical until I see evidence to the contrary.
I run my galaxy nexus with the GPU clocked to 512mhz (standard is 308mhz), and that cpu too uses the 45nm process.
Been running it like that for the last 3 months with no issue, and game fps is greatly improved.
Is there any kernels at all that even support over clocking the GNote gpu?
Very interesting, Would like to see this being investigated further for sure!
screen has nothing to do with it...on note we got 100k more pixels 1280x800-1280x720=100k
,,, and s3 has more cores in the mali-gpu...but yea i think the drivers would get us more performance

After some digging I found that the GPU In Exinos 4210(SGS2/Note) and 4412 (SGS3) is absolutely the same Mali 400MP4 (same number of GPU cores)! The only difference is that the 4412 GPU Can Go up to 400MHz (which is doable to our GPU too and have been done to the SGS2 already). The main difference here are the four CPU cores that help the GPU. I'm skeptical that the new drivers will do much (if at all) in terms of performance! Oh and lets not forget that the Adreno GPU Drivers are written by Qualcomm and they can't do anything right so the updated drivers may just be better written (or at least less buggier) than the old ones!

It has been proved to make very little improvement over a well developed kernal. Hence why developers like Franco and imyosen took it out.
Game frame rate is simply due to force gpu being active

May be...
Clocking the GPU at 400Mhz would give a boost in performance but at the cost of battery life....and also making the phone really hot....which is not idle...just wait a little while and see how will s3 perform under those conditions...
