for ASUS Z10PA-D8 you will probably find modified bios by searching this thread using "Z10PA" in search box (get file from one of top results)
after bios update change settings in bios:
Package C State limit to C0/C1 state
CPU C3 Report to Enabled
CPU C6 Report to Disabled
now you have to add efi driver to bios startup (search the forum for .efi file, the one that is for 2 CPU configuration)
you will have to execute shell cmd from within the bios (last tab I think), but your standard efi in bios will probably not support some of the commands that are needed - if so, go to:
https://github.com/tianocore/edk2/tree/master/ShellBinPkg/UefiShell/X64
download shell.efi and rename it to Shellx64.EFI
place it on root directory of a FAT32 flash drive or...
rename shell.efi to BOOTx64.EFI, create root folder named EFI and then subfolder BOOT and copy the BOOTx64.EFI there
execute shell efi from the bios (AFAIK you have to choose flash drive if you would like to boot your shell)
under shell efi:
load fs1:\v3.efi
bcfg driver add 0 fs1:\EFI\V3.EFI "V3 Full Turbo"
the first one is for check, nothing will be done
second will point bios to load specific driver during bios startup
fs1 is flash drive (could be other, i.e. fs2, fs3, etc)
you should see "V3 Full Turbo" somewhere in bios after this (sorry don't have access to my board right now)
restart and you should have all cores enabled to run at full allowable speed until any of the limit will be reached (power, thermal) - I think for 2683v3 this is 3GHz easily done
