32h with 1 GHz starving conf (MINFREQ=125, MAXFREQ=1000): http://tonism.2bit.ee/N900/starving

Actually I'm not sure what to set as the minimum frquency. Since 125 MHz voltage is lower by pretty huge amount then I tried that one. But 250 MHz vs 500 MHz voltage difference is too small to favor 250 MHz.

And as for maximum speed, I think you're safe to use at least 850 MHz. Processes get done faster and CPU can resume to idle state quicker. If 1 GHz is stable and you won't mind exceeding the voltage limit where Igor said it is okay to hold your devices constantly then go for it. I'm using that one After all, most of the time my device sits idle and when it needs to do anything it can handle the voltage just fine and does the task @ 1 GHz. Hell, the stock 600 MHz had even higher voltage!

No problem. I think we should consider ourselves among the few lucky ones who can run the starving conf stable. The statistics so far seem to be 50:50?
