Thanks! Min is 125mhz and max is 800mhz :) Observations:

1. Does not seem to get any warmer than 600mhz
2. Flash vids in browser are now smooth as butter :)
3. Ditto for a lot of Flash games that were herky jerky :)
4. MAME and PSX4ALL also play smoother :)
5. The kernel appears to scale in the (five?) steps very well and when you would expect the mhz steps to go up and down.
6. N900 is now the device it was meant to be :) ;)

The N900 appears to handle 800mhz just as well as the Droid and that has been clocked by thousands from 800mhz to 1ghz :) People are doing 1.2ghz too, but they run into a lot of heat and freeze issues.

3430 seems to (on average) hit its "safe" ceiling after breaching 1ghz.

I know it's a webkit benchmark, but it should be a pretty good measure when comparing different clock speeds.

If you run the benchmark, make sure to note your score (should be the Total up top) and any overclocks you've done.

For me: 37233.6ms @ 600mhz (stock)
26217.2ms +/- 2.2% @ 900 Mhz

Just upped mine to 900mhz - 500DSP

Conversations still stutters to open, and when clicking on conversations with people. Is this normal due to the way Conversations is rendered?

I was wondering if overclocking the DSP would increase the cell signal since the DSP is involved in the GSM part of the phone. I live in a good 3.5G area but house blocks almost all signals, get maybe 1-2 bars if lucky. I was wondering if there is a way to increase the signal by modding the phone.

I am currently running the Lehto 125-900mhz kernel

Can we actually poll the temperature sensor inside the N900 or the CPU? (is there any?)

25551.4 ms +/- 2,8% @ 950mhz - 500DSP

just had a look and it looks like /sys/devices/platform/omap34xx_temp/temp1_input shows the current temperature in celcius

(i.e. type "cat /sys/devices/platform/omap34xx_temp/temp1_input" in xterm)

I'm going to try this. N900 is getting better over time at last!

Hmm. Mine says 31. But no matter how much CPU I use, it stays at 31 and never changes.

Im Running 930mhz+500mhz dsp

Like most people said smoother over all, flash runs better, Alot less "wait" time for sound to come back after a notification sound.

Ive had no problems with stability or heat.
once we get temp readings, we need to make a wiki entry or something with info, benchmarks and such.
