Re: Overclock the N900?

I will stay away from this before I get more confirmation about safety and more easier way of doing this.

Re: Overclock the N900?

same here il stay away till we know for sure its alright, il have to teach myself how to do it then :)

Re: Overclock the N900?

Can someone build and send me via pm an modded kernel image with 250/500/550/600/800/1000mhz please ? :)

The "bleeding edge" is obviously not for everyone... :) ....

Re: Overclock the N900?

this is why a link should not be put on the forums and people should respect that

it is still in testing on the n900

the overclocking will no doubt cause more stress/heat to certain components so the n900 life could be reduced

if a link is put up people who dont know what there doing will try and flash their kernel etc and not really know why they have done it or how to do it and could do more damage then good

some people obvously dont mind testing it out and know the risks but if a public link is in action then it could defo do more damge then good to some users

Your efforts with MAME put you in the god-like category for me, but the 3430 is clocked as standard at 800 mhz in some devices and people have been using the Droid for months at this speed and higher. Temps spike once breaching 1ghz and this appears to be around where the ceiling of the 3430 is.

Again, this assumes the 3430 in the N900 is the same as the Archos 500 MP and Sammy / Motorola phones. A key for the Droid though is that SetCPU allows dynamic profiling.

Battery impact is nominal on the Droid at 800mhz, but I appreciate the N900's OS will not be the same. The evil pulse audio appears to be worse resource hog than Android's java layer ;)

A really big assumption there is that the cooling is the same...
The engineer from Nokia's comment on the issue (for what it's worth) suggested that the N900 is not designed to handle prolonged frequencies above 600 MHz.

In any case, it doesn't alter the facts as i stated them. The relevancy is admittedly highly subjective. I have my Zaurus C860 still. It's at least five years old at this point and until I picked up my N900 it was my everyday PDA. IIRC, the duty cycle of the 3430 at the N900 design spec. is not even five years, and it's probably half of that at 1GHz. I'd like my N900 to last until i have a clear and present need for a replacement, but i understand it's a throwaway society, especially when it comes to tech gadgets and in particular phones.

Re: Overclock the N900?

I want to join this bbq party too. 700 and 800mhz so only small ribs for me please :)

But a overclocking is very usefull for emulation/ video recording or playback so I want to test :)

Its propable that at 1ghz your phone wont even boot and will set itself in a reboot loop.

Very good points! Still anything to help make your great MAME app faster on the N900 sounds good to me ;)

I mentioned the heat dissipation issues earlier in the thread, but missed that caveat in the previous post. Ditto. I would hope the N900 is as robust as the Droid, but ASSUME is an acronym, you know ;)

So 1Ghz isn't stable ? The uptime here is 1m7s, how many time your phone was stable before freeze/reboot ? And do you need to reboot it many time before a succesfull boot ?
