On all the motherbords I've seen lately the CPU PNP for these chips is broken. They auto detect as 2.4v but have 2.2v stamped on them. Presumably AMD changed the spec after the BIOS code was written. The important question is why would they change the core voltage? Temperature? In fact only this week I had a motherboard which refused to boot when set correctly, but which was fine on auto. This was a _cheap_ PC Chips board though :). If anyone is is _really_ interested I can supply voltage and temperature readings, but not until monday. Maybe I should try 2.3v too. Please post if you want the data. ian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
