MCE & CPB Investigation on Intel & AMD | Sneaky BIOS

From the creator

With B&H chipsets on the horizon from Intel, and Ryzen 2000 from AMD, we're revisiting the topic of MCE and Core Performance Boost on both platforms. Ad: Buy the EVGA X299 DARK on Newegg (https://goo.gl/rcwkwY) Article: https://www.gamersnexus.net/guides/3268-multi-core-enhancement-and-core-performance-boost-testing This video explores multi-core enhancement on Intel and the i7-8700K, a CPU with a more complicated turbo table and clock binning than you might expect. MCE is present on some motherboards, and offers an option to max-out the all-core turbo clocks to single-core turbo frequencies, functionally running out of spec. We disable MCE in our testing, but we discovered that an old BIOS revision of Gigabyte's Ultra Gaming Z370 (rev F2) enabled MCE by default, silently, and without an option in UEFI. Versions F3 onward disabled MCE by default, interestingly, leaving our gaming benchmarks (and follow-up gaming tests) unimpacted. We also visit MCE on the ASUS Maximus X with its first public launch BIOS, but encounter issues getting it to work (we later found different versions of the Maximus X BIOS behave differently for MCE -- something for a future video). Finally, we test Core Performance Boost on the ASUS Crosshair VI Hero motherboard. We also test Performance Bias for Cinebench on the Crosshair VI Hero.
