Poop, I just updated to 10.6.5, but it doesn't help my X58 SLI 3 use native PM. It still panics without null. I even tried msinfo's newest pack unaltered. I guess now I sell this board and try to track down the older X58 SLI LE that it replaced, or a Gigabyte. I'm assuming the gigabyte boards can run a newer bios that supports more than 4 cores, and still work with native PM right? If that's the case, then why can't EVGA boards do it?
