I acquired a pair of Slot 1 CPUs that is supposedly a matched pair.
I've heard, that they must be of the same stepping, and Im not sure of what Im looking for.
See page 12 of:
...which discusses this issue in detail:
"Mixed Steppings in DP Systems
Intel Corporation fully supports mixed steppings of Pentium III processors. The following list and processor matrix describes the requirements to support mixed steppings:
• Mixed steppings are only supported with processors that have identical family and model number as indicated by the CPUID instruction.
[ ... ]
• In dual processor systems, the processor with the lowest feature-set, as determined by the CPUID Feature Bytes, must be the Bootstrap Processor (BSP). In the event of a tie in feature-set, the tie should be resolved by selecting the BSP as the processor with the lowest stepping as determined by the CPUID instruction. In the following processor matrix a number indicates that a known issue has been identified as listed in the table following the
matrix. A dual processor system using mixed processor steppings must assure that errata are addressed appropriately for each processor."
...and then provides twenty pages worth of charts, notes, and whatnot. :-)
[ If you get a chance, try to upgrade to Tualatin P3's, with the full-speed L2 cache and SSE. ]
