Overclockers - "How To Tell Them Apart"
Here's a breakdown of the OPN's for Athlon XP Palomino, TBred-A, -B, and Barton
AX DA 2100 D U T 3 C - The first row is in eight sections to identify the OPN:
. | . . | . . . . | . . | .| .|. | . |
. | . . | . . . . | . . | .| .|. | . C: Max. Front Side Bus speed in MHz. "B"=old 200 FSB, "C"=266 FSB, "D" = new 333 FSB.
. | . . | . . . . | . . | .| .|. |
. | . . | . . . . | . . | .| .|. 3: Size of L2 cache. "3"=256K, "4"=512K (Barton).
. | . . | . . . . | . . | .| .|
. | . . | . . . . | . . | .|. T: Max. die temperature. "T"=90oC, "V"=85oC.
. | . . | . . . . | . . | .|
. | . . | . . . . | . . | U: Vcore voltage. "L"=1.50V, "U"=1.60V, "K"=1.65V, "M"=1.75V (Palomino).
. | . . | . . . . | . . |

Stepping
(examples/core)
AIUHB = Tbred B
AIUGB = Tbred B
AIUCB = Tbred B
AIUAB = Tbred B
JIUGB = Tbred B } Generally regarded as poor clockers
JIUCB = Tbred B } " "
AIRGA = TBred-A
AIRCA = TBred-A
RIRGA = TBred-A } Generally regarded as poor clockers
AGOIA = Palomino
AQUCA = Barton
If the processor is in a running system the program "CPUID" can identify the CPU from it's registers.
Family=6 Model=6 Stepping=2 - Palomino
Family=6 Model=8 Stepping=0 - Tbred A
Family=6 Model=8 Stepping=1 - Tbred B
Family=6 Model=10 Stepping=0 - Barton
