Whether validation of at least one of a plurality of previously validated processors on a first system produced data usable for computing a validation start frequency of an unvalidated processor on a second system is determined. If validation of at least one of the plurality of previously validated processors on the first system produced data usable for validating the unvalidated processor, a validation start frequency associated with the unvalidated processor can be computed based, at least in part, on system parametric data associated with a subset of the plurality of previously validated processors that were validated on the first system. Otherwise, the validation start frequency associated with the unvalidated processor is computed based, at least in part, on tester parametric data associated with the unvalidated processor. Validation of the guard band frequency for the unvalidated processor is initiated at the validation start frequency.
