lqpl Skrevet 27. november 2003 Del Skrevet 27. november 2003 (endret) Veldig kjekk oversikt over stepping for AMD prosessorer: --------------- AMD Processors FAQ's (Post #1) STEPPINGS The stepping code is a 4 or 5 letter string printed on the CPU either on the core (on Durons , Athlons and Athlons XP with Palomino core) , or on a black label near the core (on the Athlons XP Tbred core or Bartons) . Every stepping indicates a revision/change in the CPU manufacturing process , wich usually has an impact on the overclockability and on the temperature of the CPU .

It will unlock all the multipliers in the 5X-12.5X range , except for the XP2100+ and XP2200+ with Palomino core , wich will have the 13X-18.5X range available . On any CPU you can toggle between the multiplier ranges (5-12.5X to 13X-18.5X) by changing the connection of the L10 bridges (cut one and connect the other) . The Athlon XP Thoroughbred core and Barton processors have the multiplier unlocked from the factory , so any motherboard that has the option for multiplier setting cand adjust it . The processors under 2000+ have the 5X-12.5X range available , and the 2100+ and higher have the 13X-18.5X range available . The exceptions are XP2600+ / 333FSB and Barton 2500+ , wich have the 5X-12.5X range available . To toggle between ranges , you need to connect/cut the rightmost L3 bridge . AMD started locking the multiplier on their CPUs after week 39; while some of the CPUs made during weeks 39-42 are still unlocked, all the ones from week 43 and later come multiplier locked. This applies only to the Barton core for now (AFAIK).
