well i finally got xp64 to load with raid on this evga p55 ftw board.. after many failed attempts it ended up being that i needed to install my sata dvd/cd on #0 port so it would continue to load windows.. before i figured that out i tried every way i knew.. playing with it a little today i got it to 95 blend for a couple hours at 4.0.. 1.28 vtt, 1.376 cpu.. max temp 62 degrees under water. i am going to try to lower some volts and test some more.. this is my first time playing with i5. it feels like it has a little more snap then my maximus se and e8500 at 4.0 in games..
