The Super PI world document has been crushed by a system working a Coffee Lake CPU on a Kaby Lake 200-series system, towards Intel’s platform lockdown. Overclocker Dancop fitted an Intel i7 8700Ok chip right into a Z270 motherboard, and drenched it in liquid nitrogen, to tear by way of the single-threaded pi calculator benchmark.
So, it seems to be like Intel’s Coffee Lake platform lock has been subverted as soon as once more. Intel locked down compatibility for its newest Coffee Lake CPUs to solely 300-series motherboards, supposedly due to energy limitations because of the bump in core-count, however modders have been set about proving Intel fallacious ever since.
Ready to take an opportunity on the silicon lottery? Here are the best Intel and AMD CPUs cash should buy.
Back in March a bunch of zealous modders managed to idiot Intel’s safety measures, bypass the platform lock, and get one of many price range Intel Coffee Lake i3 8350Ok processors engaged on a Z170 motherboard supposed for 14nm Skylake components. The board’s PCIe didn’t work after that, however for essentially the most half it was a convincing success. So lengthy as you did not wish to plumb a graphics card into it anyway.
The custom BIOS and hardware mod employed by Dancop to workaround Intel’s measures shouldn’t be good both. By design the hexacore chip was working with solely three cores and three threads on the Asus Maximus IX Apex Z290 motherboard, which might’ve had no actual damaging influence on the single-threaded Super PI benchmark, though Dancop later revealed the Z270 might probably assist all six cores however killed HyperThreading within the course of.
The run was accomplished in a document 4 minutes, 7.603 seconds, and was verified over at HWBot (through CNBeta). Windows XP was used for the run, and is reportedly faster on this specific benchmark. Z270 additionally supposedly performs properly with the ageing OS – therefore the mobo swap.
The Intel i7 8700K managed to hit a ridiculous 7,344MHz clockspeed powered by an much more ridiculous 1.984V Vcore. Don’t attempt that at dwelling, youngsters… at the least not and not using a wholesome dose of liquid nitrogen and a CPU that was already able to critical ranges of overclocking. Dancop additionally revealed his 8700Ok was in a position to hit 5.65GHz on an AiO liquid cooler, so it is fairly a chip anyway.
Unfortunately, it nonetheless looks as if working Coffee Lake on 100- and 200-series chips is a bit unrealistic for many informal players. This mod requires a bit soldering and no little technical know-how, and nonetheless hasn’t fairly been perfected, however at the least we all know that you would be able to nonetheless break information even with out Intel’s approval.
