The Super PI world record has been crushed by a system running a Coffee Lake CPU on a Kaby Lake 200-series system, against Intel’s platform lockdown. Overclocker Dancop fitted an Intel i7 8700K chip into a Z270 motherboard, and drenched it in liquid nitrogen, to tear through the single-threaded pi calculator benchmark.
So, it looks like Intel’s Coffee Lake platform lock has been subverted once again. Intel locked down compatibility for its latest Coffee Lake CPUs to only 300-series motherboards, supposedly because of power limitations due to the bump in core-count, but modders have been set about proving Intel wrong ever since.
Ready to take a chance on the silicon lottery? Here are the money can buy.
Back in March a group of zealous modders managed to fool Intel’s security measures, bypass the platform lock, and get one of the budget i3 8350K processors working on a Z170 motherboard intended for 14nm Skylake parts. The board’s PCIe failed to work after that, but for the most part it was a convincing success. So long as you didn't want to plumb a graphics card into it anyway.
The employed by Dancop to workaround Intel’s measures is not perfect either.
