Thank you both, I knew there was a command. Did get it working with flags for similar processor but obviously the goal is to optimize for the hardware i have. Just couldn't remember how you got the cpu flags.
If you like computers that sound like a pile of angry hair dryers servers are a real bargain, fortunately i can put mine in another room!
