View Full Version : HTC Hermes (838Pro) Actual Clockspeed, 300MHz or 400MHz

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 (http://wiki.xda-developers.com/index.php?pagename=Hermes_HardwareOverview) 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.

Go to Settings/Device Information/Hardware, what cpu and speed is showing on the page?

Mine is 2442A/400MHz

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.

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.

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?
