Those tools are usually very difficult to get to work unless you can get=20 information from your motherboard maker because various voltage=20 dividers are set by the mobo maker.. In any case measuring the temperature is only a proxy, direct (rate=20 limited!) notification of the throttling even would be better. =2D-=20 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 --nextPart27837417.CVUlm1m7aO Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (FreeBSD) iD8DBQBKqP//5ZPcIHs/zowRAlUaAKCqpzFpYke/H7qw1UVqaDGl41qQIQCggP7W dQs1RftveH4u6rtnOLni93c= =jb5h -----END PGP SIGNATURE----- --nextPart27837417.CVUlm1m7aO--
