Hardware Central heeft een artikel gepost over de multiplier lock, waarmee Intel het levensgeluk van ons overklokkers probeert te vergallen. Het artikel geeft geen oplossing voor de lock, maar probeert wel antwoord te geven op een aantal vragen, zoals de locatie van de lock (op de PCB of in de chip zelf):
If we take a look at the latest Intel Pentium II Specification Update and the Pentium III data sheets, the following comment is listed and I quote:‘These parts will only operate at the specified core to bus frequency ratio at which they were manufactured and tested. It is not necessary to configure the core frequency ratios by using the A20M#, IGNEE#, LINT[1]/NMI and LINT [0]/INTR pins during reset’
Thus the latest Pentium II’s and all the Pentium III’s have a multiplier lock that is non-responsive to any signals on the A20M#, IGNEE#, LINT[1]/NMI and LINT [0]/INTR pins during #RESET. This proves that the multiplier cannot be on the PCB, leaving CPU-core as the only possible alternative.
