I'd really like to know a little bit more about how you hit 4.05 stable. IE: Core speed adjustment via ratio or base clock, voltages, manual or auto ram voltages, Mode Line changes, etc. Any details you'd care to share I'd love to hear.CPU idles at ~26-28c depending on ambient room temp. usually stays about 3c warmer than ambient room temp. loads at ~63c under prime95 smallFFT 100% load. all cores clocked @ 4.05GHz prime95 stable and daily use stable.
