Second revision of the LGA 1151 socket for Coffee Lake CPUs (8th Gen and 9th Gen CPUs)
The LGA 1151 socket was revised for the Coffee Lake generation CPUs and comes along with the Intel 300-series chipsets. While physical dimensions remain unchanged, the updated socket re-assigns some reserved pins, adding power and ground lines to support the requirements of 6-core and 8-core CPUs. The new socket also relocates the processor detection pin, breaking compatibility with earlier processors and motherboards. As a result, desktop Coffee Lake CPUs are officially not compatible with the Series 100 (original Skylake) and Series 200 (Kaby Lake) Chipsets. Similarly, Series 300 Chipsets only support Coffee Lake and are not compatible with Skylake...
