TornadoTotalControl OverClocking on Excalibur..

I have TornadoPowerControl installed and working on my Excalibur and would like to know what is the fastest settings I can clock the excalibur without damaging it..?? right now i just have it on AUTO.. Fastest is 204MHZ

Hi, I am trying to install this program as well, but having a little difficulty finding the download for Compact Framework Version 2.0 SP1...I would greatly appreciate if you could help me out.....regarding the highest stable clock speed, I have been testing it at 252 and 264 and personally feel that 252 is pretty stable....thanks for your time.
Regards,

Here's the link i used to DL the .NET Cf.. so 252mhz is stable..? how long u been clocking at that speed for??
http://www.microsoft.com/downloads/...6b-356b-4a2c-857c-e62f50ae9a55&displaylang=en

apologize for the late reply, thank you for the link....works great, yes my S620 has been overclocked at 252 close to a month now, so far so good.....I did try it a 264 for a while but didn't really notice that much difference and plus I didn't want to take a chance on draining the battery any faster...at 252 my battery still last the whole day on a full charge with a few hours on the phone, couple of hours on wifi, and a couple of hours of watching a movie (via TCPMP)...I have it overclocked all the time at 252 even when it comes out of stanby/and after a soft reset....hope this helps....

In MY business environment, htc s620 with bluetooth enabled and push e-mail enabled, with 15-25 phone call a day, some internet browsing, without tornado power control the battery ends before dinner, and sometime also dinners are part of the business !
My Hermes? always a USB-MINI USB adapter is in my pocket! Wizard? something better! Nokia 6310i? 2-3 days!
Lesson Learned: downclocking is more important in .BIZ than overclocking!

log int xda ftp and you will find just the cab file that you need, instead of the 22 mb download from MS. i am attaching total commander for smartphone it has ftp and reg editer, if you type this into any desktop browers or pocket explorer it will login.
ftp://xda:[email protected]/ xda:xda meaning usernameassword for any other ftp sites. hope that helps.
actually both files will be in ftp excalibur folder. side note you probalby know this, but all files that need or require desktop install, just go to c:\program files\microsoft activesync and you will find the cab file, nice to store for later use. sometimes they will be seperate folder instaed activesynce, well hope some part of this was of any use

Ok i set OmapClock to 252mhz, and i set TornadoTotalControl to 228mhz.. am i doing it right?? i just overlooked my settings and now i think i have it set up wrong.. when i set OmapClock to 252mhz and set the clock its fine but when i reopen OmapClock again it reset back to 132mhz.. is it because when it hibernates the clock resets its speed?? Isn't TornadoTotalControl suppose to keep it overclocked?? hmm.. opinions please.. thanks..

YES! found: I forgot to connect the brain before starting the engine
Simply you have understoood why your S620 processor is a 200 Mhz processor, because is GUARANTEED working at 200 Mhz! Any overclock isn't, read the DISCLAIMER in Tornado Power Control before testing it at 300 Mhz!

LOL. Very nice (and polite) response!

re
other people with the same phone have reported that it is stable at 252 so why would'nt mine? What is a stable speed to overclock it to?
Thanks

Does this work better than omap? because I can't seem to get omap working on my Dash.

Because you CAN'T pair the words "stable" and "overclock", otherwise, if it was stable at 220 Mhz (or 230 or 250 whatever) they will sell it as OMAP 220 Mhz, instead of OMAP 200 Mhz!
OVERCLOCK means "OVER THE STABLE CLOCK CERTIFIED FROM COMPANY"

That is incorrect. It has nothing to do with stability. It has everything to do with optimal battery life. HTC made their phone with a 200 MHz chip because it provides optimal battery life. Once you overclock it, even 10%, you significantly reduce your battery life due to the faster CPU speed.
An OMAP CPU rated at 200MHz doesn't mean that it won't run stable at 240MHz or higher. The last two phones I've had I ran overclocked 240MHz for months without issue.
Whether or not your phone will run stable at 240MHz is a crapshoot, however... Basically, you can step up the overclocking until the point where the phone locks up and reboots itself. One or two steps below that is the "safe" overclocking speed.

This is the link to the processor scheme... the data sheet clearly state for the ARM926EJ subsystem MAXIMUM frequency as 200 Mhz
Isn't only a power problem, is also a heat problem and in some conditions it could be critical. Also the other subsystems couldn't accept data at that frequency, depending from tolerance related to building technology and may be the ARM processor works but other components (EDGE, Bluetooth, WIFI, ... ) could overheat.
That's why the overclocker builders always say: USE IT AT YOUR OWN RISK

link to TI Specs
Summarizing:
Insn't common to fry a processor just for a little (20%) overclock and normal conditions, but if you overclock more than 20% and use it at full power for a couple of ours you love to live on the edge man!

actually, you can pair the words. I am coming from a PC Gamer standpoint. Look at 3 things
1.) how long will it most likely last if I OC it
2.) Do I plan to have this device for that long? (most cases "no")
3.) can it handle my workload (gaming) without crashing or freezing. (if yes then stable, besides those companies that certify things certify them under a very strict bar.)

Another way of looking @ it is that most CPU's come in underclocked the reason why so we buy a better model, even more recently we find CPU's just with cores disabled so as they fit into the lower price bracket, so a stable clock is more than capable on many CPU's obviously depending on other factors RAM speed, BIOS blah blah blah "sorry just far too many factors"
Lets just now go back to these tiny PC's "PPC's" it's the same principle Stock frequencys lower than HTC\M$ stated the device runs @.
If my [email protected] are too warm then i OC'd too much, if the screen whites i OC'd too much, the device freezes i OC'd too much.
Sod it 240MHz and stable what more do i want? A substancial speed boost without an excessive heat load.

[Q] What is overlocking?

i searched the forum bt wasnt able to get an answer which i would understand so cn any body explain me wht is overclocking?

The clock speed of the CPU on the Tilt2 is 528 Mhz. This is the fastest safe speed the CPU is certified for by the manufacturer. Overclocking allows you to make that CPU run faster. Many do this with no ill effects. I've always had random lockups so I do not overclock.

overclocking is...
making a processor run at speeds greater than the manufacturer intended.
so. in the case of the rhodium (touch pro2/tilt2)
overclocking is increasing the 528MHz processor to a higher clock speed.
overclocking the rhodium's processor should...
in turn. increase the performance of the overall device.

[Q] Safe Overclock

What is the highest MHz that i can go up to without risking my phone too much? My ROM and Kernal lets me go up to 1920 but thats probably not the best idea.

you have reason.... NO GOOD IDEA lol
in a kernel thread (a lot of time ago...) i was read... that was not recomended overclock avobe of 1600 Mhz... And atention important!!! don´t underclock down 170Mhz more or less (because can be the devece cannot exit from standby mode when you unlock the screen....) i cannot remember what was be the thread but i really believe that there is not a concret limit for overclock....
sure that it´s not good any tipe of overclock for improve the performance...
but i have a hero overclocked at 714 mhz (factory stock at 525 mhz) since 2009 and NO PROBLEM never,,,,
and my DHD overclocked at 1200 mhz (with a quality kernel in mode smartass)
and underclocked at 245 mhz more or less and no problem....
judge by your self but use the common sense... cheeeers

At the moment i have it on smartass to 1459 max and 230 min and it seems fine. Do i just judge it on the CPU temp, and if it stays quite low (Around 30c) then im fine?

it depends buddy...
maybe its well.... the normal temp. of my batt. in use is 33-35º (but here in spain we are now at 30º !)
but my question is... are you really sure about its neccesary overclock our DHD?
I think that still DHD supports well all kinds of software with 1 GHZ of power...
maybe for a future thinks....or for gamming but always u can overclock for use a game and then return to 1ghz...
it´s only a suggestion... maybe another OP uses the processor of different mode...

The overclocking limit differs from device to device, so there is no general answer.
As a rule of thumb, when you start getting random revolts or crashes, you have gone too far.
If you want a more professional way, just slowly turn the clock of your CPU up and run a stress test after each time. It takes a bit more time but should get you pretty good results.

How long should i leave the stress test running for?
The reason i want to overclock it a little is that it just runs a bit more smoothly with it over clocked a bit. Just everything in general seems a bit better to use, its not really for gaming etc.

[Q] Maximum clock (cpu) speed

Hello.
My friend say that he can over clock this thing to 1.5 ghz but i don't believe him.
So what is the maximum clock speed?

800mhz and it's unstable.
Your friend is bullshitting. No way can a lower end single core be clocked that fast, it would simply just burn out.

There is absolutely no rule of thumb for overclocking.
One CPU might handle 800+ MHz (806 MHz seems to be reached by benjamingwynn - nice speed!) and other might handle only 760-780 MHz stable for example. Don't forget that overclocking isn't an exact science. It more like an art!
It depends on many variables: the batch, the place in the wafer where you CPU came from, the voltage you're pumping, the cooling provided, etc.
Some CPU's don't need much voltage in order to scale speed, others need a big voltage increase in order to handle the extra speed. And there are others that simply don't scale well and can only handle weak overclocks.
And of course there is always a theoretical limit.
Anyone who says that he/she can overclock a 600MHz CPU to 1.5GHz lies with all the teeth and is an ignorant, with all due respect.
I know no CPU in the world that can overclock to 150%. Not even with extreme cooling (Liquid Nitrogen or other Subzero solutions) and other crazy mods. Now imagine this on a small device like a smartphone, where you can't properly change the cooling of the CPU in order to cope with the extra heat generated.
The phone would most likely burn in smokes.
I know a little bit about this matter because I have experience in overclocking PC CPU's. I know most about Intel CPU's (Dual and Quad-Cores, still haven't touched a hexa-core...), cooled on air or with liquid cooling.
The PC I work with every day has a Quad-Core CPU that is 3.2 GHz stock (QX9770) and is running at 4 GHz. It can handle more but the extra heat and voltage needed isn't worth the extra speed (and the accelerated degradation of the CPU).
Sorry for the offtopic guys but I had to reply to this anecdote.

Well said. This is very off topic but how would you overclock on windows? You have to mess about with the kernel right?

Normally from the BIOS.
But you can also overclock from within windows using certain applications.
BIOS is the better option.

A lot of laptops have crippled bios's so there is no overclock options mainly due to the heat/cooling factor.
Laptops run pretty hot already.
Does your laptop have any overclock/frequency Settings?

All the finetuning (voltages and so on) is done in the BIOS. My motherboard is actually designed for overclocking.
It's an "old" Asus Rampage Extreme.
You would be amazed with the amount of settings it has!
It also comes with Windows software that allows some realtime adjustments but the "core" lies in the BIOS.

Nice OC aigaming! but never forget that CPU's do degrade over time, even if some people tell you the contrary.
If you keep your CPU cool and don't give it too much voltage to "eat", then everything should be fine for a long time. Still don't abuse it too much, this is my personal advice.
You have a nice cooler and with a push pull config it should keep things cool.
Mine is an old Tuniq Tower 120 (copper block lapped by me when I still had lots of patience) with the stock fan changed. I don't use the fan controller that came with the cooler btw.
My CPU used to be cooled on liquid but I have a way too limited case in order to accomodate the radiators, pump, reservatory, etc. Sold all the gear.
Keeping my beast at 4GHz on air is VERY NICE.
Once again sorry for the offtopic guys. I had to reply to this. I know I could have used a PM but I'm in a hurry.
I wish the HTC 2.3.5 RUU would have a kernel with overclock option for the CPU...
Anyone available to change the HTC RUU with an overclockable kernel?
Or am I saying nonsense? Probably CRC check would fail and I could only flash it with temp-root, right?
Would really appreciate being able to push my CPU just a little bit more...

The only single-cores I know of that can actually reach 1.5Ghz overclocked are devices running a Qualcomm MSM7x30 (Desire Z) or an MSM8255 (Desire HD/Xperia Play/Sensation XL [stock speed, same processor]/etc).

[Q] [Q?] [HTC: Buzz] Regarding CM7 CPU Settings

Hello Guys, I have searched along the internet and on XDA Forums and still have found no answer to my very specific question please try not to get frustrated with me as I have had no previous experience on Forums before and i know little about Android although I am an IT student and I do understand most technical terms and situations.
My Specs:
HTC Wildfire (Buzz)
Cyanogen MOD 7 Latest version (Stable, Not Nightly)
My Question:
I need to know what to do regarding my CPU speeds as I know that CM7 comes with the CPU Settings Functionality but I do not know what settings would be best for my Buzz for example my Buzz is quite slow and I want it to be faster for games and such and I know that I will need to increase the CPU speed to obtain this so what I would like to know is:
What "Available Governors" should I use (To speed up my phone)
What Min and Max frequency should I use?
Thank you for your help in advance and please try not to be too harsh on me :/

It can be anything your phone is stable at. For some, it is stable at 768, but, for others, the phone gets unstable at above 710/729, so, there are no "recommended" settings globally. Try from 672 and go one step higher till the phone is stable. For governors, you can use SmartassV2.
But remember though, OC'ing will only bring marginal performance games. Don't expect your games to start running smoothly after OC, because, it won't. It's not for the 528MHz default CPU speed, but it because of the lack of a GPU chip.

the best frequency for wildfire is 691 MHz, "no lags no bugs"©

Iam having overclocking about 633 MHz.....and if u r an IT student u should know increasing speed upto 700 MHz can be too dangerous....be in 600 MHz and try to not disturb governors as cm7 is a battery drainer and if u r willing to change governor then ur next thread will be battery draining lol....

True but disagreed, I can get 2 to 3 days on my current setup at 728 mhz running stable and fast, using the"interactive"governor...however go with 3xeno s above for now because every persons setup is different and will determine how far you can overclock.

howevr i hv tested a step at a time
current governererformance

What minimum speed did you select? I've just lowered the default to 176 MHz (previously/default 264 MHz), but I've read that a minimum speed below 200 MHz could even be worse than keeping it at 200 MHz. But then, this has been told about the Samsung Galaxy S which clocks a lot higher than the 614 MHz I selected for my Wildfire.
