HWiNFO shows the list of cores in CPPC order, and by monitoring clocks core= 21 is indeed the one that can clock the highest. Windows Event Viewer agrees, showing ACPI CPPC being used (performance state type) and core 40 the one with the highest maximum performance percentage (numbering starts from 0 here and considers SMT cores too, while hwinfo sta= rts from 1, so that cores 40/41 in the viewer is core 21 in hwinfo). All the ot= her maximum performance percentage values agree with hwinfo's CPPC order. --=20 You may reply to this email to add a comment.
