Overclocking with XCPUScalar 2007

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?

overclocking 6700 cpu?

I just installed the latest kitchen build on a 6700 and notice there's a performance program in the settings section, that allows for overclocking the cpu. it has a couple warnings about damages and errors etc, however I'm curious what the experiences are using this. is it safe to run all the time or what? I tried it out a couple times and the phone seems twice as fast. Any info appreciated.

I use Pocket Hack Master v4.33 and I run at 624 all day and have been for a long lone time and never had any adverse effects.

I have used XCPUScaler and I never had a problem, for Xscale processors, from what I have researched, all the program does is change the frequency of the CPU controller, Ram controller, and LCD controller. I have also read that the more power that the Xscale processor is given, the higher the speed/frequency. Well enough tech talk, the only difference I have ever seen is that battery drain is a bit more when the cpu is overclocked, never has frozen on me running at 624Mhz. Good luck.

O/C U/C

Is overclocking and underclocking too many times bad? Because usually when i'm not playing a game or traveling I underclock it low to save battery and overclock it when im on constant use. Is it bad to do it too many times?

If it's overheating, YES, ITS BAD, STOP.
Overclocking and underclocking just speed up/down the cpu.
Overclocking: The faster a cpu goes, the more likely it'll glitch (Which will usually cause a freeze or reboot in Android) and the more power it takes (Which increases heat, can melt parts). There are serious risks to overclocking. Luckily, you're more likely to crash than melt something, and if that happens just reflash the rom to get back to a lower speed (Might have to wipe the phone, depends).
Underclocking: There are no bad side effects from underclocking except maybe having a really slow phone. The Sensation is already underclocked to 1.2GHz (from 1.5GHz). Underclocking uses less power and thus drains less battery. Android naturally underclocks when it's not used heavily and every time the screen is dimmed / off.
If you haven't read up on it, though, you shouldn't be messing with it. To answer your question directly, no, constantly speeding up and slowing down the cpu won't hurt it. It does that on its own all the time.

Like the person above me said, 1.5 GHz is native frequency for this CPU. So, it won't hurt the CPU as long as you don't go higher than that.
Swyped from my HTC Sensation

Thanks for that info about what the standard clock is for the Sensation (before HTC changed it).
Now I know I can clock it to 1500 and feel safe about it.

Oh no no not that I already normally set it to 1.7 ghz and its ok.
Thats not how I meant. Let me rephrase it. Is it dangerous to o/c u/c too many times back and forth?

I got a bit off topic, I know, sorry. Android is always changing its own clock speed. When there are no apps in the foreground, the cpu is underclocked as low as it can go. When the screen turns on, the cpu gets overclocked a bit (and when you play a game, the cpu gets overclocked a lot). There's no harm at all, because Android already goes back and forth. A lot. Boot up SetCPU and just watch the current CPU and you'll see it varies in real time.
What you're doing just changes the min/max values. Change them all you want. It won't hurt anything.

[Q] About permanent overclock

Just a little question, i have a x10 mini pro, and its processor runs at 600 Mhz.
Now with the Mini CM7 i can overclock it to 864 Mhz. So i've been testing it with 724 Mhz and my question is: if i set the maximum processor speed at 724 Mhz, and leave it like that permanently, would this affect my cellphone in some way?
What i'm trying to say is, if you set a maximum speed, it doesn't means that the processor is gonna be running at that speed all the time, just when is needed, for example in games so it won't increase noticeably the battery consumption if the phone is locked 85% of the time. Or it is actually draining more battery even if don't use it?
PS. (English is not my native language, so i'm sorry if the text is hard to undestand, tried my best to explain it well).

You do know the hazards of overclocking in general right? Unless you have the proper cooling, even on a cellphone you will eventually burn out the processor. That is the real issue you need to worry about, just because you can overclock does not mean that you should overclock.

I wouldn't overclock it to the max. That's just bad juju. Unless you plan on hooking up a perpetual ice pack to the phone as well. You'd do well to be a bit moderate.
And to answer your question, yes you will burn battery quicker.

Test at different speeds. If it runs stable, with no force closes, lock-ups, reboots, excess heat, etc., then you're good. You are correct, you are only setting the maximum. What your phone idles or runs at on will depend on what governor you are using, I recommend Smartass for good battery and performance balance, although I have been liking Smartass v2 lately. Obviously overclocking will affect battery life, but you will find that your choice of governor will make a huge difference too.

Well, thanks for the help, glad to see that there are people who are willing to help with small questions like this one. Keep the good job!

CPU Tuner - Questions regarding maximum frequencies, profiles, and triggers.

This is my third time typing this... (This website should really have an auto-save draft feature)
I recently installed the application "CPU Tuner" because I've always wanted to utilize my newly rooted phone. The phone is running Cyanogenmod 7.2 Stable, and currently overclocked at 1.5GHz. My main concern is overclocking my phone that high. Now, I didn't really choose that option, SetCPU automatically set it to that when it loaded a configuration. I'm a beginner to overclocking, and this is my first time doing it for anything. I've heard rumors of people melting their processors from overclocking it, so I want to know if it's okay if its overclocked to roughly twice the stock frequency of 800MHz. If it IS safe, then why isn't the phone automatically set to 1GHz to compare to it's twin, the Evo 4G? Or perhaps even 1.2GHz to surpass it? I would definitely be satisfied with 1.2GHz, but I wouldn't mind having 1.5GHz if it was stable and didn't drain the battery. On to the next question, would an OC this high cause instability and/or would it drain my battery? I only overclocked an hour ago, so I haven't experienced any problems whatsoever... yet. On to the profiles... I'd like some suggestions for improving my triggers. Right now, it set everything up to the highest frequency, but looking at the help, it said to not touch the frequency, but experiment with thresholds. In the Help, it doesn't tell you what the thresholds are, and what they do, and more importantly, how they work. It just shows that the highest is the most battery saving. I would have thought the lower the better, but... Anyway, if you could tell me, I'd be highly appreciated it. Finally, the battery temperature... It has an option to enable a setting to change profiles if the battery gets a certain temperature, but I'd like to know what would be considered "Overheating". I get paranoid when the battery temperature gets a little warm at around 36 Celsius... but the profile it switches to is supposed to really slow down the CPU to preserve battery, so I'd really rather not use it unless it's necessary. So, would 45 - 50 Celsius do, or should I set it a bit lower? My battery is 4000+ mV, if that'd help at all. If you know any sources that you can direct me to that would answer my questions, it'd be highly appreciated.

Wow ok . Well first off check out THIS thread. It will explain a lot about Governors, I/O Schedulers, and a bunch of the questions you have. As for people melting CPUs, I've never actually seen it happen, or know anyone who has had it happen on the Shift. That's not to say it's not possible. It may be, just not probable. The Shift processor compared to the OG EVO's is much better. The Shift even at the stock 800mHz out performs the EVO's processor at 1000mHz. That is in part because it is a 2nd Gen processor vs the EVO's 1st Gen Unit. The Battery Temp should try and always be kept below 115-120 Degrees Fahrenheit. I use SetCPU, and have a Profile that kicks in to lower the OC to around Stock should the Battery Temp every reach 110 Degrees Fahrenheit. My setting are 61mHz Min 1516mHz Max, Smartass V2 Governor, and SIO Scheduler. But every device is different, so your going to have to do a bit of experimenting till you find what works for you. If you get a lot of Random Reboots, lower your Max OC setting, or try a different Governor. BTW where did you get a 4000mAh Battery?

Thanks for the response. It's pretty late, so I've bookmarked the link to read tomorrow. Alright, so 45 degrees Celsius should the maximum then. I've been thinking of switching over to SetCPU, since there are more comprehensive guides than for CPU Tuner (In which no one seems to have heard about), and it doesn't seem that the settings it set will be ideal for the long run. Although, before I switch over to SetCPU, I want to at least give it a shot. I'll change my settings so that the frequency decreases depending on battery level. Also, I don't have much but the basic governors and configurations on CPU Tuner, so I've never heard of Smartass V2 (Prior to skimming through the link you posted). Also, the battery came with it, I knew it seemed a bit different from most other batteries (From what I've seen in searches, most of them had around 2000), but I didn't know it meant that much.

The Governor settings available will depend on the Kernel, not on the CPU Controller. I've always been partial to SetCPU, but that's just me. I would again suggest doing a bit of reading, and experimentation to find your best settings. But defiantly the closer to normal the Battery temperature is the better. When the Battery heats up to much it will in most cases also drain faster. If you can post a Pic of the Battery I would really like to see it. I've never come across a 400mAh Battery for the Shift.

When I first rooted my shift 2 years ago I was very concerned of over-heating. I constantly checked the temperature. After a while I realized it is quite hard to over heat and cause damage, especially with the newest kernels the devs have put out. Just experiment with different settings and see what works best for your phone
