I have had it running at 520 for a week, but I haven't seen anywhere on here that mentions the AT&T Tilt, HTC kaiser or TyTN...

Yeah I have been running it on my HTC TyTN II (AT&T Tilt) and it does improve performance greatly. Also makes the Pantech Duo snappier. I was just wondering what it does...

@ y0himba

It is probably all in your head. I don't think the Tilt, (almost like the Mogul, just more RAM), can be overclocked with these softwares. It is a real shame as we all loved HTC Performance and Pocket Hack Master on our 6700's but can no longer overclock on the new devices like the Tilt, Titan, Vogue.

ok i just installed this.. and have it set on 624Mhz, and reset the phone..
but when i goto device info. it still shows (under hardware ) speed 400mhz..
i dont know if i am sounding like a dumb ***. but how do i know this is working?

PDAPhoneJunkie 12-11-2008 02:56 AM

Re: HTC Performance (overclocking) OEM
 
DUH. Because you have Touch. All the phones newer than the Apache don't work. The procesor is different. Learn how to search.

But that was a nicer was to sh## on me.. other then saying am a dumb ***.. LOL

So i did a little looking around and still get a little lost..
is there or isnt there a overclocking software for sprint htc touch?

You can try Pocket Hack Master v4.36 but IDK if it will work or not.

First off, this isn't new. It's getting up there in age.

Yeah but he has a 6900 AKA Touch. I dont think it will work but I dont have one myself so i cant say for sure.

nope doesnt work.. ( unless am doing something wrong ) but thanks..
i tryed the wm6 and wm5 and said doesnt work with my processor.

I know this is a little bit late, but of my two apaches, my older qwest only managed 520 stable, 624 would fail on benchmarking, or after an hour of normal use. My newer sprint apache runs 624 all day long and can run 633 with some moderate benchmarking time, 700 whatever instantly locks up.

Technically speaking, up to 624 is not overclocking the cpu in these, as these cpu classes are rated up to 624, however they take the "mid grade" cpu's that don't run at 624 but can run fine at say 520, and put them in machines meant to run at 412 or whatever. Because of this, your milage may vary from machine to machine, just as it does in any other instance of overclocking. This was done with x-cpu scalar and so it doesn't really belong here, but it does have some relevance.

I can't use the scaling feature of x-cpu as it locks me up, so I will be trying out this option and see what happens.

Oh and I'm pretty sure HTC ditched intel cpu's after the 6700, so anything meant to interfere with the cpu speeds for a 6700 or earlier intel won't work on a 6800 or higher, gonna have to find something new to play with when I finally upgrade.

No, this will not work for the Mogul. You must not read, this actually can damage your device.

My Mogul is definitely faster after this, man. Is there any way to test the actual running frequency of my CPU?

PDAPhoneJunkie 01-06-2009 09:40 PM

Re: HTC Performance (overclocking) OEM
 
It is all in your head. It will NOT work because of the dual procesor. Open TCPMP and check your "Clock Speed" Under Option>Settings. I can promise you it probably is somewhere around 385. Unless you have a one of a kind procesor in your Mogul that can work with HTC Performance...

pio_masaki 01-07-2009 02:33 AM

Re: HTC Performance (overclocking) OEM
 
Yea they have different CPUs, I mentioned this earlier (page 26 I think). Software written for the 6700 and earlier won't scale or change CPU's in the 68800 and later. Far as I know there is still no software to change the CPU speeds in the 6800+ CPUs. If it makes you feel any better, my qwest apache is plain slow compared to my sprint apache, both run stock carrier roms, it's just slower, it could just be your build is faster and that is what you are seeing.

You can also benchmark with TCPMP, though it would require a before and after benchmark of the different roms, meaning benchmark a file on your upgraded, then flash back to your stock, using the same file in the same manner (phone or sd memory) and you may get a slight difference in speed. There is variation from run to run anyways, keep that in mind. Best way is to run 3 each, and use the averages to determine if any actual increase is there.

Ok guys - I have read dozens of posts on this HTC Performance utility whether it works or not so here you go:

HTC Performance .cab:

The PXA270 Proccessor has 4 clock steps 312-416-520-624 , any of the speeds in this range are not considered over or unclocking. These processors are designed to operate at any of these frequencies which is controlled by the device.

Now, on the HTC Performance utility you will notice if you enable dynamic stepping with 520Mhz selected, there should not be a speed increase while operating on the XV6700, you will also notice as pointed out by someone else if you look in the registry that under the keys HTC > HTC_MISC you will see "EnableMonitoring" set to 1, and "EnableOverClocking" set to 0. This is because the HTC performance was designed for a PXA270-based phone that has a standard speed of up to 512, so in essence it does not do anything, especially on the XV6700 with the default clock of 416Mhz. HOWEVER, When the HTC Performance Utility is set to dynamic stepping with the 624 option selected, the reg key "EnableOverClocking" is now set to 1. Therefore, the 624Mhz option does actually overclock the system but it may not ever reach the 624Mhz, but rather the 624Mhz option allows the system to roam over 416Mhz as needed. Whereas with the 520Mhz option, on the XV6700 this option is just for the system to cap at it's already set default of 416Mhz. Or, on other phones it may be 520Mhz. It would of been nice if the HTC Performance utility show the actual max/current values but the utility was designed for another HTC phone model at 520Mhz.

Bottom line: The 520Mhz option does nothing more then the phone already does capping out at 416Mhz on the XV6700 - and The Good News, the utility does actually speed it up, but ONLY WHEN SET TO THE 624Mhz option (It enables the system to go up to 624Mhz as needed)

Even though this utility does step it up (when set at 624Mhz), I am not too impressed by their stepping alghorithm. So, here is what I did to optimize battery life and peak performance:

Using a program such as Power Hack Master:

1) Stick to the PXA27X's core clock speeds: 312-416-520-624
2) Enable Scaling between above speeeds. You can use the default scaling or I use 20%-40%-80% Ratio (Under 20% decrease speed, above 40% increase, above 80% go to fastest (624Mhz).
3) In PHM (I dont know about XCpuScaler) you can force application specific speeds. So for Java, Internet Explorer or any other application where you want full speed you can set it so when you launch the program it automatically overides scaling and forces the speed you choose.

I attached Pocket Hack Master (the latest WM6 version. It will operate in trial mode until you purchase the key to unlock.)

P.S.
I am writing a very tiny and lightweight program that will run as a process that will use a very small memory/cpu footprint. I just need to test the various speeds and optimize it, run the benchmarks, then post the utility. If you have any ideas let me know.

Find what? If you're talking about Pocket Hack Master, the one above will work on your HTC Touch...

Your HTC Touch has a TI OMAP 850 with a 201Mhz clock. This new version of Pocket Hack Master above will safely
bring the TI OMAP from 201Mhz up to 276Mhz. Just don't try to go higher...

The Power Hack Master version above works with the following:
Supports Intel® XScale™ and Bulverde™, Samsung® S3C24xx™ and Texas Instruments® OMAP™ processors

2 things..........

First and foremost, youre taking the OC thing way to seriously. By OC'ing you have to understand we are not talking about forcing the CPU to go beyond what it is capable of and cryo-cooling it. We are in speaking about running it higher than the default setting provided by the carrier.

Secondly, DONT post a version of Pocket Hack Master AND a serial number for it. You need to read the rules of the forum and community and be aware no pirated software can be provided or hosted.

Now I think its great that youre bright enough to know where and how to get what you want. But it wont be allowed here. Sorry.

My advice is to take it down before you catch too much attention.

I SAID IT IS NOT CONSIDERED OVERCLOCKING because the PXA27X is designed to operate at 312-416-520-624. None of those frequencies are considered overclocking. If you go over 624, then yes. But this processor is actually designed for 1 of those 4. Believe it or not, in some embedded devices using the same processor the default freq. is 520Mhz.

Next time please read my post more carefully.

It does indeed speed it up over 416Mhz safely without damage as it was designed by Intel this way. Again, it's not considered overclocking. HTC probably wanted it at 416Mhz for battery reasons, or for a new model with the same processor perhaps.

10 second overview:
It's a control panel. You launch it, enable 'dynamic CPU frequency scaling' checkbox, and pick the 520mhz max.

Then you forget about it, except your apache now runs like it's on steroids.

I've done some light batterymeter tests with it, and it does allow the cpu to drop down to standby/low power just fine - my idle power draw is the same 27ma (screen off but 6700 on) and the full power use is not a lot higher. I will have to see how the battery impact is during the day.

It is noticeably faster... snappier. Stable, so far, as well.

So, anyone else using it? Anyone know where it came from?

this is ok to use on our TP???

I read your post and completely understand what you are trying to say but perhaps you should go back and read mine because I said we all are aware of the current Mhz of which the processors run at and we all know what they are capable of. The HTC Advantage for instance runs by default at 624. But what I was trying to convey to you is that most people HERE will consider taking the 6700 which is default at 416 to 624 as OC'ing because the carrier or manufacture locks it in at that slower rate for various reasons. So although it is not true OC'ing because the CPU is capable of that, many here call it that because they are forcing it to a higher Mhz because it is higher than the carrier/manufacture standard. I agree true OC'ing will consist of cryo/hydro-cooling the CPU in normal cases but there is a difference of 'understanding' on here v/s a PC board. Does that make sense?

I agree... Many do think it's "hacking" the system to go to speeds it was not designed for when in fact it is...

I guess the proper term for people to use would be "Clock Stepping" or "Speed Stepping".

Re: HTC Performance (overclocking) OEM
 
Ok, I am working on a new, and eventually freeware utility that will allow better control and more visible stepping of the PXA27x cpu to it's other frequencies. Standard Frequencies that is. :-)

I am not sure if this is the right forum for this, but if there are any developers out there my question is:

I need to be able to set the clock frequency for the Intel XScale PXA27X dynamically from within Win CE. I looked to see if the Win CE Power Manager libraries (and other libraries in coredll lib) contain any functions to set the clock or least the IPM parameters but they do not. Just contain sleep modes, battery status, etc.

So, before I develop a driver which will communicate to the Intel SpeedStep Power Manager (via I2c) I would like to know if there is either another built in driver lib. or a 3rd party driver that would allow the integration to this app.

I wonder what XCPUScaler and Power Hack Master is using. And whatever method the HTC Performance Utility uses, I would love to get my hands on because there is no running applications or processes. I am thinking it is storing the new freq's directly to the IPM EEPROM or could use another HTC OEM driver...

If someone can help me with this one thing; I promise I will get you this util made fast.

If you can e-mail me at TeleProdLLC @ gmail . com

Thanks a mil!

lol - Just because one part of a device is speced to run faster than it is, does not mean that the system will tolerate it. The system was designed to run at the speed you received it running at. Whatever consequence there is for running faster is totally your responsibility. In the case at hand, it's hard to say if the reason the CPU is underclocked is because of power issues or heat issues or longevity issues or something else.

What is clear is that a lot of people have overclocked with no discernable consequence beyond needing to charge more often.

Where do I start? There are a few points needing correction. I know this processor inside and out. I hate to keep bouncing back to previous posts but you need to understand the following:

The Intel XScale PXA270, T.I. OMAP 850, and ANY other DVS (Dynamic Voltage Scaling) processor is designed to operate at any of those frequencies pre-set or dynamically scaling based on load. It's is not overclocked, it is just plain stepping.

The reason they call it stepping is because it steps the processor clock speed (i.e. voltage). The XScale (if enabled and depending how the OEM configured it) steps from say 312 to 416 to 520 to 624mhz as it needs and goes back down when under less or no load.

The reason no one has had problems with it (besides going through battery quicker) is because it is designed this way.

HTC did not set it at 416Mhz because they were afraid it would cook it. They set it for power management reasons and figured that device would benefit more at 416Mhz.

You said "just because one part of the device is spec'd at one speed just mean the system will tolerate it". The PXA270 processor in the htc IS THE SYSTEM. If you're familur with the Intel Xscale PXA27X and T.I. OMAP processors you would know that they are SoC's (System On Chips). In fact, on the HTC 6700 almost all core system control is on the 1 pxa270 chip. Really the only external chips are the T.I. DS 15xx battery managment IC, DACs, ADCs, power regulators, clock crystals, wifi transceiver, bluetooth transceiver, T.I. PCM codec IC, etc. Any system component that would be affected by clock stepping (or incorrectly labeled overclocking) is built in to the PXA270. In other words, it is designed to tolerate it.

You are right about the battery charge. That is the only reason your phone did not come at 624Mhz. HTC figures if they put it at 624Mhz it would drain the battery rapidly, not many people even fully utilize the 416Mhz, why would they need 624Mhz and pay with reduced battery life...

I promise you, no one will damage their phone at a Intel Spec'd frequency. Just don't try to run it at a frequency not listed by intel. Intel PXA270 Spec Standard Freqs: 312-416-520-624. There are a few others freqs that are not standard but stay away. You will fry it if you mess with the lcd clock, bus clock, ram clock and cpu clock if your not within spec or scaling between non-standard and standard freqs. Intel warns of switching between say a bus of 208Mhz and 211Mhz, 104Mhz ram clock and 111Mhz ram clock.

NO OVERCLOCKING... CALL IT CLOCKING... OR STEPPING... as weedahoe said, there is no external cooling or running at speeds it wasnt designed for. It's not overclocking, thus there is nothing for anything to tolerate.

gguruusa 02-02-2009 12:50 AM

Re: HTC Performance (overclocking) OEM
 
Yep, the cpu is designed to run at all those speeds. But, there's plenty of systems the cpu has to interact with that I can't begin to tell you the engineering of. What I do know is the device gets hotter than hell under certain conditions even with a reduced clock. Think of it this way...I can put an 800 hp engine in my chevette, and the engine will idle just fine. It'll also twist the frame into a pretzel. Unless you know initmately the design specs of ALL the components and how the device fared during environmental testing, which I'll be the first to admit I don't know, you really have no idea what will happen if you change how 1 part runs,...regardless of whether that single part is designed to deal with the change.

And the xscale processor is not "the system". That's way off base.

Re: HTC Performance (overclocking) OEM
 
Thats a good anaolgy with the Chevtte. Me personally, the 67 is gotten so much age behind it and no newer device has came out with the same CPE that I dont quite understand ppl still wanting to mod it and trick it out more than what has already been done. If you are just stepping on the PPC scene then I think its a good device to start out with as its like a bike, we all had one. But we all also graduated to faster and more powerful toys as well. I understand what tronnixx is trying to do but it is hard to do on a device that no one (very few ppl) have compare to how many had it this same time last year. And so with that I just think you are investing too much time on a dead star that no one looks up in the sky to see or even realizes it is there anymore.

You just made me pull my hair out... :-|
It's not off base at all. You may not be able to tell me about the engineering of it, but I can assure you that I can. I have worked with the XScale in many embedded systems. It's part of what I do...

The processor in the 6700 is most of the system, hence that is why they call it a System on Chip. I am not saying that the CPU does not heat up more at a higher frequency because of course it does, and you dont need to be a engineer to know that.

But what I am telling you is that it is designed to run safely at up to 624Mhz. Again, it will run warmer but it will not damage it.

HTC and many other OEMs choose the XScale (or other SoCs) because they contain most of the system within and therefore it means less engineering and external components.

You cannot compare the XScale to a Intel Pentium, or a car for that matter. The XScale contains MOST of the internal systems that would be affected by a clock change.

The only components external to the CPU that would be affected by the speed of the proccessor would be the EEPROM/RAM/ROM chips but it would not damage them because the requirments on the pxa270 for the memory are compatible at 624mhz too.. I did my research :-)

Now, indirectly speeding up the clock increases current draw (of course) on other components but the power devices and hardware in the XV6700 can tolerate it. It's quite a well built system.

I don't understand how people that don't understand the inner engineering of something can argue with someone who does...

Please, do your research before making such an assumption... If you would like to continue this debate on a technical level go to: http://www.phytec.com/pdf/datasheets/PXA270_DS.pdf (PXA270 Design PDF). In particular, look at Page 14 (The Block Diagram). Most of the systems built in to this processor are those that are on the motherboard in a typical PC. Such as Real-Time Clocks, Serial UARTS, etc.

How do you think they manage to fit such a computer in to a tiny case? If it were not for SoC's this phone would be twice the size!

Weedahoe: You are right, but I am only investing time in to it because somtimes it's just more fun this way :-)
