I don't use my N900 for phone calls. I never have so I have been using an early version of 125 - 800 since it first was available as a fiasco that I could load from the phone... Never had a problem and with no phone it never screwed back down to 600. I have tried the Kernel Power app but the "Ideal" kernel that it recommends has always caused a crash at boot up. If that was the easiest and/or safest and it crashed I figured I didn't need the app and went back to my old 800 MHz fiasco. The WiKi is long on technical specs but short on reasoning and I really don't have the inclination and time to find out "what's best for me" since it would all be subjective. I was hoping that someone by now would say this is what is best for the average user and these are the reasons why. That way if I get spontaneous reboots I have something to work against and when I did find out what worked best I might have a better understanding of why. Right now I would be using Titan's "Ideal" If it didn't cause my N900 to spontaneously reboot. I would tweak it if I knew which way to go and why.
