I can't believe there's a board that actually messes with VCCIO based on LLC.
That's just lame.

The GB boards definitely don't do that.
Sigh....Asus' great autovolting at it again.

You always have to set things to manual to avoid gotchas...been like that since socket 775 (back when Asus boards were killing X1900 XT's due to automatic PEG overclocking).
