I saw someone has asked about which ROM is stable and how far can you overclocked
I have a Jamin G4.
Have flashed with PDAViet 4.0.0.0.6 Touch. I have not problem at all since.
I also used Battery Status and overclocked the CPU up to 286MHz... it runs ok so far
But when I tried 299MHz or higher, the PDA hang.
TIPS for overclock:
- For safety: set
+ Ticked: "OVERCLOCK ON WAKEUP"
+ Unticked: "Remember last CPUSpeed" and "Overclock after Reboot"
- Reasons because in case if the PDA hang, a reset will put back the clock to default or 195MHz (in my case)
- Overclock less or closer to the default 195MHz is better unless you need high clock for some reasons.
I think fast clock, will use more power, therefore drain battery quicker and probably shorten your CPU lifetime
I hope this would help to answer a number of questions for someone

I am now very happy with my Magician hardware configuration:
1/ Just did a 128MB RAM (from 64MB) hardware upgrade (http://forum.xda-developers.com/viewtopic.php?t=23781)
2/ ROM Bigstorage patched to 27MB (from 7MB) (http://forum.xda-developers.com/viewtopic.php?t=23392)
3/ Upgrade to the latest ROM & RADIO version 1.12.00WWE (from 1.03.00) (http://forum.xda-developers.com/viewtopic.php?t=23288)
4/ CPU overclocked to 520MHz (from 416MHz) (using XCPUScalar 2.87 http://immiersoft.com)
does overclocking detrimental to the health of your jam?
What has been the positive and negative effects of overclocking?
thanks
I rather concern about stability. So far I found no o/c software (both xcpu scaler and PHM) run stabily on magician.
Neither have I. But maybe it's just that not all devices are created equal, and some OC better than other...
PHM works well but the benefit of oc is just small. Only few applications really feel faster and you decrease the battery life dramatically, even when underclocking (this is due to the missing voltage regulation from these softwares). My opinion: forget about it - the magician is quite fast when you keep your system clean (use the software CheckNotifications!).
The 520MHz (from 416MHz) OC brings about 10% increase of performance on average, see the attached benchmark result I made.
As I ActiveSync the Magician very often and it is re-charged at the same time, I pesonally am not bordered too much by the decrease of battery life dramatically, if any. Just my 2 cents
OT: I bet on DAVENPO!
You lost your bet! Venus won.
I personally found PHM to be a better overclocking program than XCPUScalar.
You might want to try PHM and add manually 618MHz (124,62,62,T) which gives you an SI of 329, vs. an SI of 315 of 520MHz.
618MHz gives the best performance in my case, even better than all those over 900Mhz clock rates I got by PHM's automatic settings. Some of them might be fake but some of them just gives the same SI benchmark for the same bus speed no matter what the processor speed is.
..... AND..... it does make a very noticeable improvement in running certain programs, such as the game console emulators......
Can it permenantly destroy or harm it if i overclock to lets say...280Mhz?
and also,what is the best /recommended overclocking software??
thanks
You could damage your device trying to overclock too high in theory - but it rarely seems to happen. The device most often goes to a white screen and soft resets, You have to find a stable speed for your device - 240mhz omapclock speed = 260mhz real speed -seems to be stable for most people.
Use omapclockplus http://forum.xda-developers.com/viewtopic.php?t=56057&highlight=
Or batterystatus (with today plugin) http://forum.xda-developers.com/viewtopic.php?t=55782&highlight=
Or you could use omapclock with smartskey or memaid/sktools
choice is yours :wink:
I haven't had any problems so far, but am running it modestly overclocked @ 247 Mhz. I am using the batterytodayplugin, works great.
Possibly I'll bump it up another notch to 260, but for now I don't need that extra speed...
One advice - go slowly. Increase in increments, and wait a few days between each higher overclock value. That way you can determine if it is stable.
i know this might b a stupid question and a question that has been asked alot... i did a search and couldnt find an answer but my question is what is the highest you overclocked your phone and it was stable? im currently running at 240 stable and im sure this will answer alot of questions for anybody who is new to overclocking thx in advanced
dont really think that that many people push it to the max
as both ram speed and sd ram interface being a much bigger bottleneck then cpu
so overclock is more likely to cost precious batt time then anything usefull
I've noticed that my MDA becomes unstable after 230 or so. I'm using an old 1.08 IPL/SPL rom if that has anything to do with it. I have Battery Status so I just use the CPU scaler and it works pretty well.
I'm running @ 232 and have been for months with no noticeable additional battery drain. Running a more-or-less stock WM5.
When i have some high quality video files or a bit more complex software that wizard can't handle at standard frequency (like quake), i run it @260MHZ without any problems. I went up to 273MHz a few times, and it worked fine with TCPMP, but i never used this setting for more than about 20 minutes. When i used different programs (not only the video player) and switched between them (read: normal pda use) i had a few system frezes @273MHz, so i don't consider it a safe setting
I use Battery Status to scale between 147 to 247 with boost set to 260. I have never once in 4 months had it lock up. I use a very stable rom though so that has to help. When using other less stable roms I was getting lock ups often.

what is the highest that the wing can be overclocked and what would be the best program to do so?

You are prob going to be slammed with 'use the search feature', but, I'm bored as hell at work, so I thought I'd help.
You will find many people use different speeds, and different programs. The two I've used are batterystatus and Omap. Personally, I like batterystatus, and I've safely clocked mine to 299mhz.
BatteryStatus? Isn't that way old?
I highly recommend HomeScreen Plus Plus (which is the new version of Battery Status) just google it and you'll find it and download the Advanced verson not the Basic one.
And I safely overclock it to 299 with no problems. I went to 312 once but every so often the phone would rest itself.
HS++ is also good cause it auto underclocks and auto overclocks your device so when your phone is sleeping it saves battery .

+1000000 this is awesome man! thanks
i want to thank everyone that had responded i did a little research and i was confused. ya see i am using batterystatus .04 and if i go above 260 my phone freezes and to be quite frank i had 2 wizards that i believe died from overclocking. they both one day randomly after a reset went to the bootloader screen and stayed. i had tried a hard reset and flashing the unit with no luck personally i dont have a clue what happened and with this one being my only source of 'net access i cannot mess it over once again thank everyone whom responded

Hmm wow I'm sorry for your Wizard but the Wings can go up to 299mhz without dying and the good thing about HS++ is that if you enable CPU Scaler and set the overclock to say... like 400 and your phone freezes, just plug in your charger and reset your phone. The CPU Scaler is disabled as long as you have a power cord plugged in your phone (your phone stays on it's native speed) so you can just go back into the CPU Scaler overclock settings and lower it and try again ^_^!!
So just use the CPU Scaler to find the highest overclock speed but never just set the overclock speed in the normal overclock menu. Use the CPU Scaler auto overclock option and you won't need to hard reset your phone.
thanks for the advice. so it is possible to kill a unit with overclocking i just wanted to be sure, cause when i asked in the wizard forms if i am not mistaken no one answered me. i had also asked hct via a number provided to me by tmobile and they said the stock "i dunno we will have to look at the unit and that will be $180" towhich i responded f**k!! that i can get a new unit for under 130 off of ebay then got a wing....

I've found this neat tool: http://www.nuerom.com/BlogEngine/page/nueDynamicClock.aspx
Has anyone used this on their X1 and did you notice any changes? I don't think you can use it for overclocking an X1. But I'm thinking about setting clock frequency to 19 MHz on Suspend, to get more out of my battery.
I've got this tool, not sure if it made much of a diff when I overclocked it to 528
( or just set it to the base clock speed since they have it underclocked @ 400 mhz ), wanna try the lower speeds, but not sure whether it will have a negative effect.
I uninstalled it..
found that any apps (such as gps cycle computer, audiomanager etc) that played with the screen on didn't work very well when the speed was lowered. Also had quite a lot of instances when the screen was corrupted after coming out of suspend..
I use it since yesterday, so i can't say anything about changed battery lifetime. But i got it working only after setting min-clock to 384MHz. With lower settings the phone got frozen in standby mode after a while. I'll try it for a few days for testing a (hopefully) enhanced standby time...
PS: i use 384MHz in suspend mode and after idle time of 5s, didn't change max clock or voltage settings (all to "auto"). Maybe setting idle time to 2s would care more battery life, but i don't know how the cpu will stand changing the clock so much often...
Been using it since v1.0. Seems to have some battery gain (10% over 8 hours better) - set to default 528MHz, down to 256MHz idle and 122.98MHz on suspend and screen off. Needed 123MHz for clean audio playback in standby.
Only screen corruption (inversion) issues I had was when set too low (19MHz) at standby. Now using these settings for a few days and no issues so recommended for use with TFlo3D2.
Unless you're running WM6.5 with WM7 titanium - makes it very slow to respond out of standby.
And it doesn't overclock - 528MHz is default clock speed.
I wanted to try this but my X1 says no, here is the screen shot, due to security, I press yes and my X1 does a soft reset, then I try the program again and get the same thing.

Has anyone with a standard Official Rom 2 got this to work, and how ?

I have a standard R2A ROM and it works for me. Can't tell you what's the problem with your installation, though.
Anyway, I found since I installed the tool my device is worse than before. It sometimes interrupts audio playback when display is off (ALthough frequency in that case is still at 3xx MHz!) and sometimes it takes very long (5 secs +) to suspend and to wake up again. So I think I'm gonna remove it.
I only turned down the voltage to 1.1 instead of 1.325 running on 528MHz.
