Hey kink, PhenomMsrTweaker is amazing, I've put it on every single K10 machine I've come into contact with.

I was looking at adding K8 support for a friend that's on an athlon 64 x2 6400+, and I'm not sure what to change to let phenommsrtweaker run on his system.

From what I can tell, I think what I need to do is add a check for a 6400+ (or any K8), using CPUID I think, then change all the Msr calls for K8 FIDVID and P-state stuff. I'm pretty sure 0xC0010042 is FIDVID_STATUS, and 0xC0010041 is FIDVID_CTL.
Does that seem correct?
I got this info from this pdf.

Also, the newest version of PhenomMsrTweaker broke MinVID for me. It's the default 0.0125V instead of the old 0.775V on my PII x2 550. Same goes for my Sempron 140. This isn't a bad thing, as min voltage on the sempron is higher than what I have it set at

On a side note, how do you figure out what fan controller the mobo has?

Thanks for the great software,
