  he 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 .
  
  Duron Spitfire:
  
  600-800: AKAA < AKCA < AKBA
  800-950: AKCA < ALCA < AMCA = ANCA < ANDA
  
  Duron Morgan:
  
  AHHAA < AHLCA < AHLDA
  9 < Z < Y
  
  Athlon Thunderbird :
  
  AXHA = ALUM < AQGA = AGGA = ASHHA < ADFA < AJFA = ARGA < AXIA = BXIA = AVIA = AXIAR < AVHA = BVHA < AYHJA = EYHJA < AYHJAR
  9 < K < Y
  
  Athlon Palomino:
  
  AGKFA < AGKGA < ARKGA < AGLHA < AGNGA < AGOGA < AGOIA < AROIA < AROGA
  9 < 4 < K < F < Y
  
  Athlon Thoroughbred :
  
  A : AIRCA < AIRDA < AIRGA < RIRGA < RIWGA < RIUGA < AIUGA < AJUGA
  
  B :

  UNLOCKING
  
  The Duron , Athlon Thunderbird , Athlon XP Palomino processors have the multiplier locked from the factory , and to unlock it you must connect the L1 bridges . 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 .
