at a recent gigabyte event, documented by extreme tech, overclockers hit 7.5ghz with an intel core i7-7740k kaby lake chip on the skylake-x platform. in addition, the overclockers used a corsair ddr4-4333, a corsair ax 1500i power supply, and gigabyte’s x299-soc champion motherboard to break records in 3dmark03, 3dmark06, and aquamark.

in order to reach these new benchmark totals, the overclockers used liquid helium, which reaches temperatures as low as -250°c.
while this sounds like an amazing achievement, the writers at extreme tech cautioned, “as interesting as results like this are, they don’t actually tell us very much about how chips will overclock in conventional systems or when using the equipment that normal overclockers are likely to use. the amount of energy you have to dump into the cooling system to hit extreme temperatures grows significantly as clock rates rise, from simple air cooling, all the way up to dry ice, ln2, and beyond.”
the article added, “there’s little evidence that slapping a modest oc on a cpu meaningfully shortens its life, but the same can’t be said for the chips that get used at these overclocking events.”
