Happy to report my results. i5 9600KF R0 stepping confirmed working with ASUS Maximus VIII Ranger. No isolation required. Just the SKT_OCC mod. Will do the board level mod in sometime and share with you all.

Built with Coffee Tool 0.99
Need to flash with programmer. Use FD44 to extract board data. If flash fails with programmer, flash with USB BIOS flashback after erasing BIOS chip with programmer.
Also,
