Hi Dan3; That 5-10% guard band is before taking into account temperature and voltage operating ranges. P.S. I finally found some articles that talk about pin costs for modern IC packaging. Posted the links last night on the RMBS thread. Taken a look yet? I think it's time to do some sort of bang/buck estimates re RMBS vs wide busses... -- Carl

Re: "If temp is taken into account, is another 5 or 10% added on? So if a process is expected to yield 800MHZ CPUs at 70C, then the chips should run (briefly, at least) at 900 before errors occurred and (at least some of them) should run at 1000MHZ at 45C before errors occurred? Or does the 5 to 10% take into account temperature?" I think the guard band spec is at operating temp (65C) or maybe (85C) - not sure exactly. I'll ask around for confirmation. THE WATSONYOUTH
