Intel Core i3-8100 8th Gen Desktop Processor, 4-Core, LGA1151
The Intel Core i3-8100 is a desktop processor with four cores and four threads, built on Intel's 8th generation Core architecture, codenamed Coffee Lake. It runs at a fixed 3.60 GHz with no Turbo Boost, backed by 6 MB of Intel Smart Cache within a 65 W thermal envelope. It installs in an FCLGA1151 socket on 300 series boards and supports dual channel DDR4 at up to 2400 MT/s, which suits it to entry desktop and industrial systems that need predictable clocks rather than peak throughput.

Compatibility and integration considerations
The FCLGA1151 socket is shared with earlier Intel generations, but this processor runs only on 300 series chipsets, which Intel lists as B360, B365, H310, H370, Q370, Z370 and Z390. It will not boot on 100 or 200 series boards even though it fits the socket, so verify the chipset rather than the socket when ordering against an existing platform. Boards that shipped before this generation launched may need a BIOS update before they will post. Memory runs in dual channel DDR4 at up to 2400 MT/s with a 64 GB ceiling, which is a lower speed and half the capacity of the i5 and i7 parts of the same generation, so check the memory kit and populated capacity when substituting. ECC is not supported. Integrated Intel UHD Graphics 630 requires display outputs on the board, and cooling should be rated for 65 W.
Typical use cases
This processor is the entry four core Coffee Lake desktop part and appears in office desktops, thin clients, kiosks and signage controllers that were qualified on 300 series boards and do not need Hyper-Threading. Because it has no Turbo Boost it holds one clock under sustained load, which is useful where thermal and acoustic behaviour must stay predictable. Most demand is replacement and fleet maintenance on platforms that would otherwise have to be requalified on a newer socket.
