Once I finally get booted up with my Ballistix / Team combo, everything is good. I can power down without any problems. It's just that initial boot up after a clear CMOS that is causing a big problem. I'll play some more later to see if I can find out what works reliably to go from no boot to boot with DDR2-667 junk memory to boot with good memory. I thought today that you might have to do two boots with the junk memory and get all the voltages right and then switch in one stick of the good stuff and hope it doesn't dump your settings. I've been very happy since the Reapers arrived and I'm glad I don't have to go through this maddening trial and error except when I'm testing. For me, when the FSB starts going way beyond 500MHz, it's all worth while.
