The question is often, how to overclock and there is a bunch of thread on that, but what about "downclocking" ?
I was thinking of that to extend my battery life when using low CPU consumption programs. Is there a stable program that can be recommended (my processor is a Samsung SC32442 400MHz Processor) ?
Thank for your support !
I would also be interested in something like this. Also a program that could suspend different parts of the phone would be nice. I would really like a program that could shutdown the display when playing mp3s on the pda.
I try to overclock my Qtek9000 to 624 MHz using XCPUScalar 2007. If i fix the speed to 624MHz, it works well for several hours, but after that it freezes. If I click to control the speed depends on the CPU load, it does not work.. I have JW ROM 2.02.02 installed. If somebody overclocked Qtek9000 with stable wrok after that?

why do you want to overclock it? does it make a big difference?

Yes, it does! Even starting several benchmark programmes, the performance is much better... Of course, if I have more ROM will be better, but CPU 624 is OK.

I wonder if there is a real application to increased CPU speed except getting better scores in benchmarks.
No, I'm serious here. Contacts, Tasks, Outlook, SBSH programs, eWallet, VehicleManager. TomTom, at the end -- it's working OK already.
Does it make difference if we're getting 0.85 seconds instead of 1.00?
I really would like to know what should I overclock my device for (and risk overheating it).

I had been using X-CPU Scalar for more than a year and a quarter now. My Universal is a year and a half old. I have mine set at 520, never over-heated, never felt it had any increased in temperature of any kind, and still going strong.
But isn't 520 the normal speed of a Universal anyway?

I'm at this opinion too..
The speed and overclocking is connected to the CPU type (not to the PDA itself). I have Inetl PXA270. Initially it is rated to 520 MHz, but saw in internet there is some PDA with the same CPU (PXA270) but officially made on 624 MHz. Maybe this CPU is designed to work (stable!) on 624 MHz as well...

You're not doing anything at all. The default speed is 520mhz. You're just hogging RAM by running the X-CPU.

Not necessarilly. You have to remember, different apps run at different speed depending on the system which WE DO NOT HAVE CONTROL until overclocking apps were available. The system normally slows down its speed to conserve battery. But to me, speed is more important, like in answering calls and activating my BT Headset, maybe this is the reason why I have no missed or dropped calls. Never had delays in anything. By assigning the system to run all apps on 520, it assures the app will open fast and react fast as it should be. At least this is how I understood WM system management of open apps.
I just read in Intel website that XPA 270 can be run at 520 and 624 MHz. There are a lot of PDA (HP iPOD etc) running on 624MHz.. so why we can not overclock it to 624 as well?

There was a similar thread that answered your question months ago. Try searching for Pocket Hack Master or XCPUScalar.
iv been running mine fine for ages, mines on auto scale its running at 520mhz anything below 15% cpu power being used, and 624mhz above

Yes,what he is doing is right.The default speed is changing between 520MHz and 108MHz according to the percent of the CPU load.Keeping the speed at 520MHz can make Universal run faster.

It's not just about getting better benchmarks. Have you tried running 640x480 videos or play games on your universal? It works fine right? But it works and looks better if you overclock it.
There's really no risk. It wont allow you to overclock beyond 624Mhz, which is still on the safe zone.

But if I overclock to 624 MHz, it will run ONLY at this frequency! No reducing of the speed depends on the CPU load... In this case, what about the battery life?

That is something you have to sacifice with speed. I don't care about battery life since I am using an extended battery anyway.

uhh... no it won't.
cpu speed is TAKEN, not GIVEN.
if you set cpu speed to a 624mhz and a certin opp pnly needs half, it will use ONLY half.
thats the job of the "system idle process", to "save" the rest of the cpu speed to other programs.

You are right if I do not use any Overclocking software. But if I use Xscale or Hack master, they speed up the CPU to 624 and disable the "system idle process" and keep the CPU running on maximum speed , does nopt mater that I do not use any programmes or services...
If there any way to overclock the CPU in "bootable mode"? Similar to the PC BIOS?
What is overclocking and underclocking? What is available For our phone? How to do it?
Sent from my GT-I9003 using XDA App
Over-clocking->
By default our phone has a processor with a capability of a 1 GHz speed. But, the processor can do more. To make the processor do more speed is OVER-CLOCK. Currently, We have a Over-clock kernel of 1.1 GHz. Overclocking can heat up your phone and lessen battery life
Underclock->
If you feel your processor is heating up a lot or you dont need a large processor, there is an option to make the processor do less work at a lesser speed. This is underclock. Underclocking may give you more of battery life, but, the speed of the processor is decreased.
I dont think we have an under-clock kernel. But, here is a OC kernel:

From looking at overclocking options for my pc, I've seen 3 possible things to overclock
1) the processor (cpu)
2) the graphics card (gpu)
3) the ram
Obviously we have done the first one, and recently started on overclocking options for the second one, but how come no one has tried overclocking the RAM in our phones? Is it even possible and would it be beneficial to performance? What about underclocking or undervolting the RAM as well to save battery?
Is this the one option we are missing or is it just not possible?
It's possible. But because most smartphones are SoC/SiP changing specific hardware options are pain in the ass. Most of the chip schematics are simply hard/impossible to get and thats the problem. How can you possibly tweak voltage or speed if you don't know much about chip itself?
