Longterm disadvantages to overclocking?

Has anyone noticed any long term disadvantages to overclocking the Wizard? Does the battery life permanently decrease? What speeds are you running yours at, and how long have you been doing it? Have you noticed anything at all which indicates it's not good for the hardware?
Cheers

i believe that it's safe to overclock the mda...just set it at an acceptable rate (264mhz for me) and make sure not to run the battery all the way down...if you overclock the settings too high the device will freeze and reset (this is a fail safe procedure it goes through), so there is no need to worry...also don't overclock the settings too low as the phone becomes disfunctional when too low (about less than 132mhz for me)...the screen flickers because it's not being refreshed quick enough (my guess)...hope this helps...

I would set it to 240. I have done before, i'm just wondering if it's a bad idea leaving it permanently set to that level?
Cheers

yea you should be fine at that speed, but if you want you can overclock it higher if it will let you...just make sure that the phone is stable when using it...like i said in my earlier post my device is oc at 264mhz

Cool, thanks for your replies. How long have you had yours overclocked for? Do you use Smartskey?
Cheers

My self i ownly use it when need the extra speed, only with some games and wmv video files. I think it definitely lowers battery life and i would have worries about overclocking all the time and the long term effect it has on the processor (not so important if you only keep your wizard for a year and then change with a new contract - what i do new device once a year!) I found good speed gains with the registry wizard - http://forum.xda-developers.com/viewtopic.php?t=39725
have not found overclocking produces that much extra speed.

Mine is also set at 264 24/7. Battery still lasts me all day. Been doing it since the oc program was found which I guess has been a couple of months.

Don't forget, you're wizard is only overclocked when it is active (i.e. not in standby mode). When your wizard goes into standby, it automatically goes back to the default 180mhz. Only when you bring it out of standby does it overclock again (assuming you're running it with smartskey with the option of overclocking on wakeup)

i'm using smartkey to constantly run at 264mhz...i have been doing this for a month now...like i said there is not really any problems with the batt unless you run it down totally...there was a post about this in the overclocking thread...the process is set low so that the phone will have a longer batt life...this was also stated in the overclocking thread...theoretically there is more wear if you overclock it since you are making the processor work harder, so use it at your own risk! if you want to be on the safe side then use smartkey and the overclocking prog in the same directory...then use total commander's note pad (while the ini file is highlighted) and change the value lower when you don't want it to constantly run at 264mhz or whatever speed you want to overclock or underclock at...just use it when needed, but i overclock mine constant 264mhz with great results combined with tweaks2k2, registry wizard, and of course the tmobile custom rom ...internet is a blast...just wish i could get it to run like the IE in a pc
anyways hope this helps out a bit further...

activesync
your activesync will hang allot if you overclock, I have noticed this.

DOnt know why.
For some reason i stumbled onto something, im sure its been mentioned b4 but when running Wisbar advance with a Windows vista skin done by xcillion, i am able to overclock my cingular 8125 to 288mhz at a stable rate with no problems at all, can run warcraft 2 full speed with over 50 units battling it out on screen, almost doubles browsing speed and i can run all the emulators including SNES at full speed with sound. when i dont have wisbar advance running i cant go past 240mhz clocking speed. I wonder has anyone else noticed this or gone higher than 288 without a freeze. Also, my battery life runs steady for a full day of browsing the internet talking on mobile messanger and listening to music at half volume for a full day.

hey sonic, where did you get your copy of warcraft 2 for windows mobile ?
I've never heard of warcraft for Windows mobile, how does it run on a 240 MHz overclock?

I got it from the Wargus engine. i can email you the files if need be, i dont want to jeprodize this sites reputation. The game last time i checked was free though...

Actually I'm not sure if it's the overclocking issue or not but ...
For couple of weeks now my Wizard's red led is on all the time, not like it is when your battery is very low but about half of this brightness. I'm not really worried about that, it doesn't change much but it may be connected with overclocking (it was 240 for about a month).
Another thing - once I had sth like 110% speed of every tone played, either a phone call or an incoming message.
It doesn't really matter to me since it's still working fine but it may mean that overclocking isn't that safe as we might think.

Wizard heavy processor usage

Hi,
I'm having trouble with an app which runs on some other PPC2003/WM5 machines OK, but struggles for speed on the Universal (edit: corrected machine type - put in wrong name due to total brain fade).
I've been investigating processor usage, and on the wizard "devices.exe" is using 25-30% of the processor time when the machine is completely idle. The problem app never manages to achieve more than about 40-50% processor usage - which I guess may explain why it runs slow!
Does anyone know what is using up all the processor power, and if there is anyway of disabling it. I tried removing the SIM card, and turning off WiFi, but this had no effect. Something is using a large chunk of processor time, but I can't find what.

Which app is that if not confidential? I can also give it a try.

It's a kind offer and it's not confidential but ... it's also not publicly available, sadly.
The problem is the Loquendo speech synthesiser, running inside our own app. Loquendo runs in it's own process so I can monitor usage separately. The problem is it cannot generate speech in real-time - and yet it can do so on lower spec-ed CE machines.
What I can't work out is what it is in the system that is gunging up the universal. Perhaps it is just a bad OS configuration by HTC - but I hoped that it might be something in particular that was loading the processor, which could be killed off.

ameo running slow

as others, after installing lots of softwares on my ameo, it's running extremely slow nowadays.
I already reduce to keep those software I do require.
can anyone recommend any solution. thx.
I knew this is a general question and try to search in the forum. unfortunately it comes up lots of irrelevant result. :-(

If you're still on wm5, the first thing you should do to improve stability and speed is to upgrade to wm6. For me there was a world of difference.
If you have already upgraded and still find it slow, then one of the things you should rule out is whether or not it is caused by problem in reading and writing to the card or microdrive. Do a few rounds of performance test using Sktools a and are if they are normal still. If there are lost chains or cluster,repair them using pocket mechanics professional. Alternatively,copy the content to pc using wm5torage, reformat the card/drive,and copy them back from pc to card/drive. Redo the sktools performance test to ensure speed has improved. The last time when I had your problem ( soon after my wm6 upgrade), I did this and performance has been very good since then. Oh, I forgot to mention that one of the reasons I experienced sluggishness was due to incorrect formatting parameter for my card. When I format them correctly, speed improved dramatically.
If your MD is very fragmented,you could do what I recommended rather waiting hours and hours for defragmentation to finish.
I also try to install frequently used program in device memory,and seldom used one or very large program such as dictionary on microdrive. I have close about 50 third party software so the device memory isn't enough to hold them all. I find that speed also suffer of i'm low in device memory. So, don't waste it on things you seldom use.
Let's do that and see if speed improves.

thanks for your helpful tips. Eaglesteve. I will follow your hint to speed up my ameo. I am on WM6 arleady. probably as u point out, sw installed on MD is slowing down the device.
Forget to mention that, my device is always running at high cpu load. >90%.

Running at 90% could be a real clue. Have you installed any programs to improve your bluetooth performance?

whatabout device storage memory remaining? If it is critically low it will also prevent program from starting and making them slow. If so, check the size of internet temporary file in windows directory. If needed, go to delete them. I just did for mine and freed up over 50mb of device storage memory!

Low CPU speed to conserve batt

I have been playing with BS Ext for about a week now - very nice tool, thanks!
Question 1:
Has anyone thought of keeping CPU speed low when your device is sleeping (screen off, etc) regardless of app that may be running in background? I am trying to conserve battery life, of course. When the screen is off my phone will run progs (e.g. check for mail regularly) and I truly do not care if they run slower since I am not watching them. Since BS is essentially based on CPU usage or program I do not see how this could be accomplished.
Question 2:
This may seem silly but I thought this prog was not yet released (still in beta) and I am getting shareware notices.. Even if I was ready to purchase the code I could not easily find directions indicating a) how much and b) how I would get rid of the pop-ups. Could anyone advise?
Thanks in advance!
Cheers!

Substantial memory leak

Hi,
I've noticed that over the course of a day, the memory consumption of the HD increases substantially... going up from about 30% to over 60% if I use it heavily. I imagine it has something to do with the different caches and the tweaks I've run (found on the forums) to increase performance. Is there a way to flush all caches so that I don't have to reset the device?
Thanks!

I'd like to know if anyone else is having this problem too.
After a fresh reboot my memory usage is about 30%. By the time Gyrator and TouchFlo restart it gets to about 40% where it stays.
However once I start using programs it will easily skyrocket to about 70%. Even if I close all the programs using taskmanager I will never recover more than about 2-3% of memory.

i use memmaid to free memory from time to time, but i we also backup a request for something that automaticly do that
shadow option for sktools made my hd to stuck so i rennounced to it
any ideeas?

now i don't know if this can affect battery performance but with computers the most efficient system is NOT the one with a lot of free ram, is the one that USES it totally... virtually having always ram at 99% would mean maximum performance... In other words: why do you want to flush the ram

This can not affect battery performance at all.
And it's totally normal to use ALL ram.
I guess you people grew up with normal Windows, that frees ram...
For example Linux has always used 99% RAM on your pc. It just uses all the free RAM as cache! So when there is more needed, it deletes some cache and allocates that RAM.
It is bad, very bad to waste memory by not using 100%. Using all memory for cache and only giving memory when it is needed is good for performance.
If you look at Vista, it does the same thing...
So it is normal behaviour, especially when you set all the caches high.

I use the SKTools application "FreeUP RAM" which does a sweep of RAM and normally saves about 5-10 mb.
BUT, I find I rarely need it as I don't seem to have any memory leak except with TomTom running.

i am not sure i can follow you
if i understand well, linux keem memory ocupied in order to fully use the whole capacity
but is not the case of windows, and sure is not the case of windows mobile
in my device, diferent processes and application take a slice of memory and does not release it even when you close them
so you end with a memory occupied 60, 70 even 80% despite the fact that you have nothing obviously running
because of that (not having enough free RAM), when you launch a new application, the HD became very slow or even stuck
correct me if i am wrong, but this is what i have noticed during the years of use of windows or windows mobile.
i am not computer literated so i might be wrong, though!

I also raise this problem here before, most expert's advise is that WM will manage memory itself, it is not necessary for us to do anything!!
I had tried to use memmaid, but it only free up 1-2M memory.
Back to the time when I use D810, if there are few MB left, I can't launch new application. Even when I close some and make free RAM left to 16+ MB, that program will still report out of memory........the only thing I can do is to soft reset.....
HD's RAM capacity is much better, but as time goes......maybe this problem will also happen!?!?

Sorry but not convinced. I agree that when in use 70-80% memory usage is not a problem. But when there are no programs running, then there is no reason to use ram.
Also on my previous wm6.1 device when you closed items in task manager it would restore ram. Sure not all of it but a good chunk of it. Heck, even on my previous HD using the task manager would free more ram.
The only thing that I can see that is different between my previous HD and this one is Tweak HD and the TouchFLO Calender. So I will try removing those first and see what happens,

Eventually, after flashing Laurentius's ROM, the problem went away almost completely. Have to say my memory usage is pretty stable now, at around 40-45% even after a day of full application and web use.

dunno personally i'd love to have a superfetch feature like in vista which keeps ram full

Higher memory usage causes minimal/neglectable effect on power consumption, RAM is powered as a whole, fractional/partial modes (where only used memory cells are powered) are not available on modern RAM chips. The CPU or DMA controller may use more power swapping memory data in and out as memory usage grows, however the increase is nothing in comparison with what the LCD backlight or loudspeaker would use.
I don't know what memory allocation method is used in Windows CE/Mobile, but regardless, being unable to start a new application while there are no other applications running in the background means that physical memory is depleted and this is not normal. OS may use RAM for caching/buffering to optimize performance, however memory allocated for optimizations should probably be released when it's required for other purposes. If this is not happening, than either OS lost track of allocated/unallocated memory or memory allocation approach is very inefficient and causes high fragmentation.
Here's a list of tools (for WinCE) that may also work on WinMo and help curious xda-devs figure out what's eating their memory...
