If so, I consider that a worthless number, because >of obvious reasons... If done properly and tested for reliability -- what reasons do you speak of? Most CPUs are purposely locked from higher than marked performance from the manufacturer for marketing and other reasons -- both Intel and AMD. This, in no way, means the CPU is incapable of such performance. In the case of AMD, chips with the same stepping are identical no matter what they're marked. So if a 1500+ AthlonXP has an AIUHB 0301 core and an AthlonXP 2800+ has an AIUHB 0301 then they'll be able to run identical speeds. (Obviously there are slight variations in peak performance, if you're going for higher than XP3000+ level.) Are you suggesting that "unlocking" performance that is already included in the core simply because the marking on the top of the cpu says otherwise makes such results worthless? Wouldn't that be the same as saying stronger results I may find with Crafty if I modified the settings are completely worthless if you did not include the settings in your official release? -elc. P.S. ICGA doesn't have any regulations on the overclocking of any CPU(s). :)
