Some one has posted the overclocking of OMAP 850. I have personally tested it by changing the clock rate from 180 to 240. The speed of loading and execution of program has greatly improved.

Nice!

Any ill effects?

P

Any noticable Battery drainage ? Any Apps not working properly? What's the highest someone has clocked so far?

I have overclock from 180 to 240. Here is the result of running a same movie clip for the same amount of duration. The TCPMP display the clock speed of 225 instead of 240.

It shows that there is an improvement on the avarage speed.

I'm running at 240 all the time now, and it feels WAY faster!

P

aint this gonna burn it out or ruin the processor at all?

As an old film used to say,

It's better to burn out than to fade away

Highlander I believe...

"I have something to say... it's better to burn out, than to fade away... there can be only one...."

Soundtrack by Queen, effectively all of the 'A Kind Of Magic' album, one track from which features the above quote.

Damn i'm full of useless information

Hey Paul , How did ya do that? Mine defaults back to 180 after time out :cry:

I used SKTools to set it up in the Notify queue.

A bit long winded, but worth it!

P

my C600 runs at 288Mghz.... after overclocking to 240 I add one by one measure and "change now" effect the clock before add more. like 240, 256, 265 etc (i don't remember exactly).

BUT
after 288 (300) it freezes. In apps emu like Pocket SNES it shut down the app after few min.

After stanby wakeup my clock returns to 180 (default)

I don't understand your "queue notify" or what.... what's that stuff?

can it run video in tcpmp full screen then now? (encoded with pocketdivx I mean..?)

This is how you set it up to always run at the speed you want with the use of MemMaid:

Instructions for overclocking Wizard (tested on Imate K-JAM)

--------------------------------------------------------------------------------

Instructions for overclocking Wizard (tested on Imate K-JAM). Use at your own risk!

1. Download the following file and unzip. Save the OmapClock.exe to your \Windows folder on your device: http://forum.xda-developers.com/download.php?id=9181

2. Open File Explorer on your device and open Omapclock.exe. Find the maximum speed that your device will handle without locking up. On each test, test all applications you use. This is important because once you place this in your startup, it will load up automatically and could cause your device to stop responding! 240Mhz works for me. Suspending the device at this point will cause the speed to be reset back to default. Execute Windows\OmapClock.exe again if this happens and you want to continue testing.

3. Download and install Resco File Explorer 2005: http://resco.net

4. Open Resco Explorer and go to the \Windows folder. Locate the OmapClock.exe file and hold the stylus on this file until menu pops. Choose “Copy”.

5. Now browse to \Windows\Startup then hold stylus in an empty area and when menu pops, choose paste shortcut.

6. Hold the stylus on the newly created OmapClock shortcut and choose Properties then click the Shortcut tab.

7. Target should be: “\Windows\OmapClock.exe” –clock 240
Change the 240 to the clock speed you tested in step 2 above.

8. Soft reset and test. Suspending the device will reset the device back to the default speed. This is a secondary test to make sure the device does not lock up!

9. Download and install DinarSoft MemMaid: http://www.handango.com/PlatformProd...23995&R=123995

10. Open MemMaid and choose the Notification queue button/tab on the bottom (second from left) then click the ADD button.

11. For Program, click the browse button and browse to the shortcut you created in steps 5-7. The location of the shortcut is \Windows\Startup.

12. From the event dropdown choose “The device woke up”.

13. Click Add.

14. Soft reset and you are done. The Clock speed will remain at the specified speed you specified in step 7 even when the device comes out of suspend.

What's the battery life like, if you overclock?

I've been overclocking mine to 252 for a week or so now, I've set it so I have a shortcut on teh Today screen, press it and clocks to 252 straight away, saves battery power etc, but even running it most of the time it doesnt seem to impact the battery life, not as much as wifi anyway!!!

You guys wanting an around-the-clock overclocking, then this lead might be usefull, I have not tested it as I do not feel like overclocking just yet, wants to get more familiar with the device and it's performance before doing so.

From Xda-developers forum:


anyway check out the lead:

Do have fun you all....

Guys/Gals,

Installed the new K-JAM Rom yesterday with Direct Push which is very nice and seems to improve performance anyway.

Also running Smartskey and Omapclock and running at 264mhz without a problem. If I up to 276 it crashes.

Jason

With my MDA (USA) I can get stable at 276, at 288 it seems to run stable and I even got GXMark to run, but later when I tried to go into it again (After having returned the speed to normal) it froze as I changed the speed. Anything higher automatically freezes. Does anyone know where GXMark stores its results?

Hi All,

Said earlier that I wanted to get a bit mor familiar with my device, I have used the past week or so testing the overclocking part of my device... and well it is great, especially for TCPMP and Powerpoint, i do run some rather large presentations and overclockign actually makes them acceptable on m device, not great but acceptable...

I do however use a bit different overclocking option than the rest of you as I do not want an around the clock overclock. Just when the performance is needed...

I altered the shortcuts to the programs I want to use in overclock mode, works like a dream...
Some people have had issues o icons changing to th OMAP icon, the string examplified below solves that problem...

64#"\Program Filles\OmapClock-v0.2\v02\OmapClock.exe" -clock 240 -launch "\Storage Card\Program Files\TCPMP\Player.exe" -restore?\Storage Card\Program Files\TCPMP\Player.exe,-0

Quite a mother to key in, but it works flawless, speeds up while working the app and slows down afterwards...
