sir that tweak makes my phone reboot...

You haven't really answered my other questions. Though I guess previous overclocking attempts (regardless if failed or successful) may have potentially caused hardware damage with the device.

The screenshot from top isn't helpful either, you need to be the one viewing it not us. There should be at least a process under CPU% somewhere that is causing the device to overheat. At least with the CPU being maxxed out it will use its maximum specified frequency.

Also with conky running, you can see on where it says Load1 avg. DIO. Mem. Those are also some of the useful fields when you have conky running for at least 5 minutes.

The load average is over 5 minute intervals, its collected from uptime command, the DIO is most likely Dynamic Input/Output and Mem is obviously memory usage. If any of those are high, notably load average or DIO it means that there is a process/kernel thread somewhere that is hanging up or some process that is thrashing I/O.

An output of your dmesg (into pastebin) along with maemo-list-user-packages would be handy.

im the owner sir.. and sometymes i success overclocking and sometimes failed becauseit it reboot itselt when i aplied the latest batterypatch... the only one problem is drained battery and overheating when browsing.. but when i used it for music or movies it doesnt heat..

any patch or command to avoid overheating on browing and gaming?

I think your definition of overheating could well be a normal situation as the cpu will go 100% on any computer when browsing, the other factor could be the battery losing the ability to hold a charge and you can only check that by replacing the battery.

Gaming will for sure make the cpu high in usage and could very well be why your device is getting hot but i still say you need to check the battery first and take into consideration what your actually doing on it to overheat, so far you have picked the 2 most common high cpu usage as in gaming and browsing.

ahm okay.. it is affect to our phone?

Yes i would certainly say so, it is because you not know anyone else with a N900, they DO get very warm when being used.

You guys asked way too advanced already without asking the basics first....

Answer my question first before theirs.

1. When browsing what sites do you open? Does it require flash player to load? How much windows are usually opened when you are browsing? Is it some basic wap sites or some of the xhtml high loading sites(detailed sites)?

2. When playing games, what games do you play with your device if it's overheating? Is it some of our roguelike games? or preenv? or some of the GLES games ported to maemo? or even some of the emulators available here(PSX, GBA, nes, snes, amiga, sega etc.)?

maybe its the weather, n900 gets hot sometimes, especially with apps open, on a cold weather its gotta feel warm, but unless its burning causin 1 degree burns its usually that way.

Could you please install qcpufreq (or I don't know if health check reports temperatures) and post the temperatures? Mine is 36,3C and it's been idle and normally clocked. It gets up to 47 some times under heavy usage and overclocking to 1000.

Notice that qcpufreq reports tenfold temp under certain configurations so don't panic if you see 380C
