tried with newest fennec nightly:
17750 @ stock
something like superpi for the device would be pretty nice, it would allow us to exclude the error the browser induces.

First "visual artifacts" here: returning original settings with transition control, after "restarting desktop", menu bar starting to display white lines...and beauty colorfull effects when closing transition.
After restarting, all ok again.

(950-500)

Well, living in Israel I think it would be risky for me to OC it above 800mhz haha. Especially since it's going to be summer pretty soon.

I just had a realization: At 1GHZ the N900 is more powerful than the HD2. Since it has a GPU unlike the Qualcomm devices (HD2, Nexus One etc etc). It's pasically as powerful as an iPad at 1Ghz.

Not completely true, the SnapDragon has a 600Mhz DSP on chip. (correct me if im wrong) So its 1ghz + 600dsp vs n900 1ghz + 500dsp. But it are 2 different processors, not comparable! i think the n900 will beat the snapdrag at 1ghz! And for the ipad.. dont know! time will tell ;-)

How do you check clock speed?

i guess it would be faster than the stock HD2 even under 1ghz.... but even the HD2 can be overclocked, so.... lol

I have had artifacts sometimes on stock kernel so it might have nothing to do with the overclocking.

That said, I am running 900Mhz stock DSP, until someone has stress tested overclocking the CPU and DSP. Overclocking both just seems like asking for trouble and surely stuff that utilises the DSP by its nature is using less CPU power, so you shouldn't really need to overclock both.

The iPad is dual-core and I believe has a VASTLY superior GPU to the N900, not remotely comparable. But then I can't put the iPad in my pocket, multi-task on it or use it as a phone.

I don't really get what the DSP speed actually does.. Could someone kindly explain it to me please?

As far as I understand it, the dsp is used by the GSM radio, and can be programmed by the host for arbitrary code execution (some people mentioned video codecs but I'd be surprised if that was true).
