<<There must be fuses present to make exactly what you are saying possible. There is a functionality to disable individual cores in BIOSs (at least I have seen it in benchmarks of Intel QC chips). Those are temporary, blowing fuses in testing is permanent.>> U can disable core in BIOS if the chips are fully functional. A non fully functional die might not boot up if the dead core is used to start execution. So on power-up, the cores that are functional must be known. Even if there is work-around, MB and CPU are often not sold as a pair by intel. So have to be on package (similar to multiplier) or blowing a fuse on die.
