edit: I don't think Powernow makes any difference - see AMD PowerNow!. My question is, why add this feature on a 4p server board when the article talks about notebooks and battery power savings? Weird.
I think the recommendation is to disable PowerNow to increase performance slightly. PowerNow lets the CPUs drop bellow 2Ghz when they are not fully loaded I would guess and then they take some time to get back to full frequency which impacts performance.
