Disabling CPU Rendering on Adreno 200 GPU & Overclocking the CPU

    I have seen a lot of talk on the mod to disable CPU rendering on Adreno 200 GPU's to speed up everyday tasks and improve battery life. I'd like to get some opinions on whether or not this might be beneficial to the Venture. Im not a heavy gamer or anything. I tend to use my phone as more of a utility. The sluggishness of the 600mhz msm7627 is killin me. Im wondering if this mod would (hopefully) help with lag between switching screens, lag browsing the app closet, etc... Is there any chance this mod could cause bootloop or brick? Also, ive seen that our same chipset has been released with overclocking to 800mhz from the factory. Considering that fact, i would assume its safe to give it at least a small bump? Maybe a little over 700mhz? Any input is appreciated!

    Here's a link to a description of the mod: http://forum.xda-developers.com/showthread.php?t=1887997

    well much of the sluggishness you are experiencing on the 600mhz is due to the sheer amount of bloatware on the phone. You will notice a significant speed bump and see it become more responsive overall once you clear out the crapware. As for cpu settings,ill step back and let someone with more info on that jump in.

    yeah, i have noticed an increase in responsiveness in the harmonia rom for sure. i just figured that it would probably become more sluggish again once i installed my usual apps and filled up some of that internal storage (which isnt hard to do with how little we have). i suppose i could try using app2sd to keep my internal storage clean, i just havent tried playing with it yet. as for the overclocking, i tried searching overclocking for the venture and came up with squat, so i figured getting a little device-specific info on overclocking available to the public would be nice! ;-)

    i bet app2sd would be highly beneficial for this phone. i freed up a ton of internal system memory by dumping almost all google related crap and tried to eliminate as much of the vm stuff as i could. some of the apps i didnt recognize so i left them. the total rom size i ended up with was 75 mb. that should streamline the rom.

    App2sd isn't sufficient for this phone, we need more severe measures. App2sd leaves the .dex file in the dalvik-cache and various other bits and pieces elsewhere in internal memory. Instead, use link2sd. You'll have to partition your SD card but it's a big improvement.

    It still isn't perfect; on my phone the stuff doesn't stay linked when I reboot, instead the OS (I assume the OS is to blame anyway) copies the .dex files back or re-creates them. That means I have to have enough internal memory to support them all while booting (until I run link2sd and tell it to re-link dalvik-cache) or some apps will be broken after rebooting. However, it's much, much better.

    For the general slowness I suspect it's as much slow memory I/O as it is the slow CPU.

    Overclocking would require kernel source. But once we had source it would be quite easy!

    On my wife's phone I mad a custom app2sd script to mount a 2nd SD partition, then copy over data/app /data/data data/dalvik-cache, and /data/app-pdivate over to the 2nd sdcard partiton, then bind mount all the things on the 2nd partition back to /data. This works better and causes less issues than symlinking everything like traditional app2sd and link2sd does. Now she has almost a gig of space on he phone!!

    would you be able to make this script work for this phone? and does it have the same issues like bovine was talking about in link2sd does? 32gb sd card = crap tons of space with what your saying. im down to do that, if its possible

    Yeah I have it running on my wife's phone at the moment!! And from what she's used it everything works great! Ill make a flashable zip here when I get a chance for you all. You will just need a 2nd sdcard partition formatted as ext3. I used cwm to format it cause I had issues using newer versions of mini tool partition wizard. But yeah and the good thing about my script is it checks to make sure the 2nd sdcard is mounted and if not the script exits out. And it checks to see if the directories have already Ben copied over to sd-ext so it ain't trying to copy everything over evetytime at boot. But yeah my wife's phone works good and where it moves all the directories that take up alot of space in data, then depending on how big your 2nd sdcard partition is, then you can have all kinds of app space and it will always show over 200mb free on data. You just got to keep an eye on how full the sd-ext partition is using root explorer or something!

    can you walk me thru making a new partition on my sd card? i faintly remember how to do it thru linux, alas i havent booted into linux (ubuntu 11.10) in months. but i always have my pc dual partitioned for linux and winxp. yea know....just in-case *cough* i have to wipe my windows partition.

    Space usually won't slow you down much on solid state storage.

    As for the apps, it depends on how many are running in the background. Bloatware is bad because it's usually older apps written by a desk jockey who was told by his boss to write it and never uses it themselves. Apps you install tend to be done more often by people using them and give a darn about how they run, though you may need a premium version to get the full benefit.

    Would you mind simply posting the script to this thread? The reason I am asking is the following:

    I have a HTC One V and it constantly reboot loops as soon I have a certain number of apps installed. I thought it may have been code.google.com/p/android/issues/detail?id=25563 but since I installed a custom ROM (Amazing Sense) with 4.0.4 (apparently it was fixed in 4.0.4) I have not more luck. I makes my phone close to unusable. There is not much, that you can fit onto <768MB of free flash.

    Now I want to try the Link2SD trick mentioned in the issue as workaround. However, I do not know where to find the 2nd partition, so I could mount it on the phone and format it with a filesystem. I got no Linux system here, only OS X, so I can not mke2fs here, must do it internally on the phone (I got a term and the commands on it).

    I just need to know, where Android or HTC has the 2nd partition in the /dev directory. I have more of this here, including a full "mount" and "ls /dev/block/vold" output: forum.xda-developers.com/showthread.php?p=33767454#post33767454

    P.S. Links crippled due to anti-spam measures, since this is my first post to this forum.
