I have successfully changed the PagePool size on a Touch Pro rom!

[aceracer24]

Traditionally, when it comes to PC's, a dynamic page file is considered a bad thing. Most people will make the pagefile static and 1.5 to 2.0 times physical available ram which in most cases helps computer performance.

For mobile phones, the page pool is used in the same way but there is far less available memory to create a pagepool that would function for all programs. If you use a static pagepool and a program requires more then what is available, then you get a slower responding program. If you use a dynamic pagepool, that same program will use all available memory that it needs which in theory should make it respond faster. Since every program is different, a dynamic pagepool makes sense. You don't have to commit to any specific memory size.

I have not done any benchmarking or testing but I have been using dynamic pagepools since I found out you could and for me the programs are at least as fast as everyone else that uses static.

looking into jd's rom i could not find that string...any clue as to the lines you found them?

Well all I can tell you is that I can change the Page Pool just fine with the Page Pool changer I posted. You see the difference in memory however it is a special rom and not available here. When the PPC kitchen drops this weekend you will not have to hex anything and will be able to use the Page Pool changer. Just ask Colonel.

Cheers,

I'm not familiar with jd's rom. If it is built off of the stock rom for the Sprint Touch Pro, try this hex string for the default pagepool offset:

03 15 A0 03 06 16 A0 13 00 10 83 E5 3E BB FF EB

Your statement is a bit misleading. What about folks who do not plan to use the PPC kitchen or roms built from it? The original reason for providing the pagepool offset information and instructions to modify it, referenced in the Diamond upgrades forum, was for educational and learning purposes. Keep in mind, in its present form and when it actually works, the pagepool changer does not modify the dynamic/static offset thus creating only static pagepools. I encourage folks who are comfortable with hex editing to try various combinations of both pagepool sizes and types. We all use our devices in different ways, with different programs and have different expectations for performance.

you may need to disable the 'Case Sensitve' feature when you are searching for the string

03 15 A0 03 06 16 A0 13 00 10 83 e5 3e

you rusky help me out plz.
I edited
03 15 A0 03 06 16 A0 13 00 10 83 e5 3e (string lines 5BA51 and 37F704)

to

20 16 A0 03 06 16 A0 13 00 10 83 e5 3e

in hopes of getting the 32 megs of static...
Immediately after flashing, I removed the battery for a few mins, and booted up to install WM... Memory still shows 203megs. Any suggestions?

**EDIT**
I also tried changing the string to 18 16 from a fresh nbh (JDs) to the same effect. Please help?

there are two strings and you must change BOTH of them, after you search and change the first one click search again and do the same thing for the second

[Tilde88]
