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 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?
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.
is there any work being done on being able to overclock gpu?, being a gaming orientated phone it seems the obvious thing to try, I've had a look and been unable to find anything about it. gpu overclocks on mobile devices are rather massive from what ive seen thus far.
or has any work for doing this on phones with the same chipset been completed that we could work off in the future?
cheers

Adreno is part of the scorpion chipset, it's not a dedicated GPU and thus cannot be overclocked independently, obviously overclocking the CPU will help somewhat, with games, but only on performance not graphics
Ah, unfortunate limitation on this chipset, yep cpu overclocking looks like the way, thanks for the reply.
Hi I was wondering if it was possible of overclocking the GPU in our phone.
Has anyone heard about this being possible or a project that is being worked on for this?
As I understand it, since the MSM8255 is a "system on a chip" design, when the CPU is overclocked, the GPU is as well.

would there be anyway to simply oc gpu and not cpu?
Most probably not.
Once I did the analysis for Adreno 200 on MSM8250, you can look it up in Nexus One Android Development forum. I've explained in depth, why it isn't possible, as detailed as I could without disclosing the actual clock diagram. I believe the same applies to MSM8255 - though I didn't check to make sure.
Actually in the Desire HD forums, shaky153 said that you was working on a kernel to over clock the gpu of December 2011. He was able to over clock the gnu at 245 Mhz as stated in the beginning of the thread but it wouldn't stick and revert back to 192 Mhz. As of now he hasn't updated his process and is most likely abandoned and his account is a guest account. If he is able to over clock the gpu then it would be easily ported to the MyTouch 4G both being HTC and having the same processor
Judging, again, by the work I once did, the fact that he "thought" he overclocked the GPU doesn't mean a thing. If he executed a function that says "Set GPU clock as X", doesn't mean that GPU clock will be X. In fact, it might affect nothing at all.
To overclock a part of SoC, one needs to know the SoC clock diagram. SoC isn't PC, where each function is governed by its own controllable PLL, it's different.
I still think its odd that the Adreno 200 and 220 gpu can be overclocked but not the 205.

220, being more advanced, most likely has more granularity in its clock divider. It figures from the frequency steps it can do.
200 can't be overclocked. Only together with the CPU.
205 is most likely in the same situation as 200. Not necessarily, but most likely.
Again, some things about clocking should be understood before talking about "overclocking". The clocks don't come from the sky, and this is not a PC.
Actually there is a thread on Overclocking the adreno 200 gpu on the htc desire from something like 96mhz to at least 200mhz which gave an enormous improvement. They were trying to get Fifa 12 to work. LINK: http://forum.xda-developers.com/showthread.php?t=698940f. And just because i ask doesn't mean i don't know. I know how to overclock PC gpu and know the difference between a PC and a Mobile device. And i definitely know that cores aren"t everything. Tegra 3 is never going to beat a Intel Core Duo just because it has more cores. And no poop, clocks don't come from the sky, that's common knowledge.

Look at the CPU frequency with overclocked GPU.
Then think, why the hell did they go that low in CPU freq.
Then you're welcome to dig into history and read my thread in N1 forums, dealing with GPU overclocking on QSD8250. If you have some brains, that will tell you why it didn't advance anywhere since 2010. Let me give you a hint: dividers aren't PLLs, and their capabilities are hard-coded and can't be changed to anything but their allowed values. But let me guess: that you write you know something doesn't mean you actually have a tiny bit of clue what you're talking about, and my previous sentence remains a black hole to you.
Now, as I said, I didn't look at the clock diagram of 8255, so I don't know whether the same limit remains here. If I'll have some free time and will be able to lay my hands on it, I'll have a look. But as I wrote in the old N1 thread: the likely answer is the one you're not going to like.
Having said that, since I'm tired of trying to explain how stuff REALLY works, I won't return to it unless I find the clock diagram and it will say something positive.
Thanks for that, Jack. Some people need a reality/ego check.

Anyway to check if the guy who posted that he was able to overclock the gpu is legit because pulling up his account come up with invalid or something.
For a side note, wasn't some xperia devices with adreno 205 gpu over clocked? if heard/read correctly, is it possible to use the similar method and overclock the desirehd gpu or are the frameworks getting in the way and what not so it wouldn't be possible. I would like to milk this device to its limit if possible.

For ALL devs.
I remember an old post of our belove Blades (Kernel's Dev), that talked about the possibility to push up RAM frequency, not only timings. Today can we reach this goal on our TF101?
"Testing out memory timings that may bite you.. If anyone can help cut through the bull**** that is MC/EMC clocks... just chime in here.. Originally I increased (slowed down) the timings and bumped up the clock by 33mhz.. and got fail. So... advancing the timings it is.. They are pretty pitiful stock.. What really pisses me off is the missing 33mhz (and thus 66mhz from emc).. we could use that... Well.. lets see if waking up the wimpy timings helps".
So, a new challange on the road!

I would like to see this continued but I remember running some beta tests for blades with different timings and we found that the quality of the RAM in our TF101's was not that great.
If I remember correctly blades said because of the RAM it was not viable to do it and also that the way the timings had to be done was warped to say the least.
I think he had one or two updates with it but then stopped.

Really dangerous. I've been messing around with it a bit and it looks like the RAM chips in most devices can't handle higher clocks properly.
Also, not all batches of RAM chips are the same quality, just like with Intel and AMD CPUs.
Some may clock a lot better than others. It would be almost impossible to find clocks that work fully stable for everyone and really actually speed.
and finally,if someone do this change in ram's freq. sure there will be the need of many types of configurations,becuase our ram is ****ty,and not the same like you have sad.then a dev have to do many types of kernel with different ram's bumping,to accomodate all the users out there.my tab has an "elite" tegra2,never had poblems with blades kernels with tweaked timing and ram,and never had problems also oc to 1.7\1.8 like first elite kenels made by clemsyns
in the 2 type of ram packaged with tegra2,Ventana type,we have the lpddr2 at 300 mhz..i'd preferred to have the others one,ddr2 at 333 with a little more speed (2.66 compared to 2.4)
in the total of types of ram in the market,2.4 gb\sec is very very poor...i don't think that upping the freq. can apport so much performance's gain in this Soc..
