Greet news T07N, glad to hear your happy! Heck 600Mhz isn't all that bad, lol! Although it may run Orthos for a few hours with no problems I've occationally had errors after multiple hours of Orthos. It might be a good idea to run Orthos overnight to make sure things are stable (try to run more than 8hrs if possible). Alot of people have different ideas of what "stable" really is, some think being able to run SuperPI's 1M test means their system is stable and others like myself like to run many hours of Orthos/Dual Prime before rig is stable?
