Wow, that's weird, wish my AMD would do speeds like that :) As for your temperature observation - I have no idea sorry. It would appear that powerd is doing the right thing but for some reason your CPU is not benefiting. That said checking by measuring temperature is fraught with complexity because there is probably a significant delay between a change in power consumption and a corresponding chaange in heatsink temperature. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQBDxfGV5ZPcIHs/zowRAijzAJ9uJXaQ0XgIV9UYoxtpaZw3Te+PdwCgnn6M ATwdNzY5Sy2tbhV0r+v7tEc= =eAO2 -----END PGP SIGNATURE-----
