Socket and chipset constraint

This Intel Core i5-8600K desktop processor fits only LGA 1151 sockets on 300 Series motherboards. It has 6 cores and 6 threads running at 3.6 GHz base with a 4.3 GHz maximum turbo. The 9 MB L3 cache and 14 nm manufacturing tech support DDR4 2666 memory in dual channel.

Enthusiast builders and VR-ready systems

The unlocked multiplier suits overclocking enthusiasts and VR-ready builds. Integrated UHD Graphics 630 provides display output at 350 MHz base and 1.15 GHz max dynamic frequency. Buyers needing a boxed cooler or compatibility with older chipsets should choose a different model.

Unlocked multiplier for overclocking

An unlocked multiplier is the single specification that decides whether this is the right part. It allows manual frequency tuning beyond the 4.3 GHz turbo limit when paired with a Z-series 300 Series board and adequate cooling. Without that requirement a locked alternative would be more appropriate.

Questions about this item

Which motherboard socket is required for the i5-8600K?

The i5-8600K requires an LGA 1151 (300 Series) socket motherboard. It is only compatible with Intel 300 Series chipsets.

Can I keep my existing DDR4 2666 memory when installing this processor?

Yes, the processor supports DDR4 2666 memory in dual-channel mode, so your existing modules will work at their rated speed.

How can I verify the CPU is reaching its maximum turbo frequency after setup?

Monitor the core clocks under load; the processor should hit 4.3 GHz on active cores when thermal and power headroom allow.
