thats's it. I used to run at 1100 but now 1000 as I don't need it for now.
I also use ulv instead of ideal in hope to be more stable all day long.
Not doing anything extra fancy.
oh. I use d-livil's Blac Plastic theme 2.x which has an awesome custom transition that makes everything feel much snappier as well.
what does that mean in terms of frequency?
oh and have you found a work around for the incredibly laggy scrolling?

Alright, grab my kernel config first:
http://junkiez.org/maemo/kernelOC
after installing the power user kernel from the repository (reboot if you haven't done so), follow these steps:
copy kernelOC to your N900 (/home/user/MyDocs) over USB
open xterminal and do:
sudo gainroot
mkdir /home/user/.kernel
cp /home/user/MyDocs/kernelOC /home/user/.kernel
open kernelOC in nano to edit to your needs:
nano /home/user/.kernel/kernelOC
read the # comments in that file, should give you a good idea of what you're after.
after you're done editing, save with ctrl+x (then y, enter)
then, if you're sure your settings are kosher:
kernel-config load kernelOC
if it doesn't hang up or reboot immediately, test out a couple of videos in media player/browse the web a little bit. If it doesn't lock up:
kernel-config default kernelOC
Now, your N900 will have essentially my same settings, for a bit of other tweaking:
nano /etc/init.d/rcS
scroll down to almost the end of the file where you'll find comments stating the following:
# adjust other kernel parameters to minimize memory consumption
# and optimize IO pressure
change the values /proc/sys/vm/swappiness and /proc/sys/vm/page-cluster to read:
echo 50 > /proc/sys/vm/swappiness
echo 0 > /proc/sys/vm/page-cluster
save and exit nano.
if you'd like to swap from your sd card, please partition it with a swap partition and use a script titled 'swapmod' in /etc/event.d like so:
nano /etc/event.d/swapmod
enter the following:
start on started hildon-desktop
stop on starting shutdown
console none
service
script
swapoff /dev/mmcblk0p3
swapon /dev/mmcblk1p2
end script
Please note, the above partitions - /dev/mmcblk0p3 is Maemo5's default internal swap location, and /dev/mmcblk1p2 is the second partition on the sd card, assuming you have created a swap partition on your sdcard and want to use it and it alone.
http://wiki.maemo.org/Swap_on_microSD for more details.
Let me know if you need any help.

oh cool!so whats with the "-" ?
what does that mean in terms of frequency?
oh and have you found a work around for the incredibly laggy scrolling?

and no, there's no real fix yet for increasing the frames nor enabling vsync unfortunately.

hmmm..any ideas on how to get vsync in the scene?is it due to lack of hardware or is it just the software thats missing?
n alright guys i know im a lil off topic but i have a problem that does not seem to be solved. see, the phone feels great once i over clock it.but after a day, it gets depressingly laggy and freezes randomly when there are sudden processes running. but after a reboot, it runs fine again. do you guys reboot your phones every two days??and secondly, overclocking seems to work for a day, but then gets back to its laggy self later..u noe SUDDEN LAG spikes and freezes..btw, on conky, my "Mem:" is at a constant red.(its right below cpu usage on the right)
does that have to do with anything?i really wish i didnt have to reboot my phone once in a while cuz it is quite battery consuming.
help!

mine has been up for a week at the same clock with no stability issues, or no variation in 'snappiness'. When running conky, look for any offending processes - processes using large amounts of cpu cycles/memory. If you haven't adjusted your cache/io pressure, I'd suggest you do that, as it makes a huge difference with longevity.
On another note, the lack of vsync lies only in software - the drivers for our PowerVR chipset. The iPhone 3GS has virtually the same chipset, but has vsync functionality. So, it isn't a limitation of hardware, just an oversight on the agreements with PowerVR. It may come eventually, but it'll be fixed in MeeGo, which we will undoubtedly get - whether or not is supported officially (who cares!)

wow, thats great news!last thing, how do i adjust my cache/io pressure :$?(small tutorial <3)
n r u sure the mem below the cpu usage being completely red is not a bad sign?
i think thats my problem!
my cellphones been on for 2 days and it quite horrible..gonna restart right now
!thanks alot man, youve been a great help!

/etc/init.d/rcS is essentially the file that calls all of the actions that happen when you boot the device up - things like starting the hildon-desktop, activating partitions, setting environment variables, etc.
Swappiness is a variable that indicates how much the system will prefer physical RAM over using virtual RAM (swap space). The default setting in Maemo5 (up to and including PR 1.2) is 100, which means it nearly always preemptively swaps - even when not needed. Setting it to 50 (or even 30, when using the internal swap partition), will nudge that balance a bit - make the system use up physical RAM (which is significantly faster than swap space) before deciding to use swap... in a nutshell.
As for my config, I can upload and post it, and will write up a tutorial to help the process a bit... bear with me, I will reply to this thread when complete.
