I tried ideal as the first profile to try out. It rebooted on it's own in a fit of spazzims within moments of booting. Had sound issues and the cell radio stopped working. That was at stock speeds. Saw others on the boards mention that they had reboots from trying to run with too little power, so i switched to ULV and haven't had a random reboot yet. Aside from the weird sound glitch everything is going pretty well.
