Core i3-8350K quad-core desktop processor

The Intel Core i3-8350K is a quad-core desktop CPU built for LGA 1151 sockets on Intel 300 Series chipsets. It runs at a 4.0 GHz operating frequency with 8MB L3 cache and four threads. The 14nm Coffee Lake architecture suits mainstream builds that need consistent single-thread speed.

8MB cache and DDR4-2400 dual-channel memory

The processor supports dual-channel DDR4-2400 memory up to 64 GB total capacity. Integrated Intel UHD Graphics 630 runs at 350 MHz base and 1.15 GHz max dynamic frequency. The unlocked multiplier allows frequency tuning, though the four-thread limit becomes apparent in heavily multi-threaded workloads.

Intel Optane Memory support and integrated graphics

Intel Optane Memory support accelerates responsiveness when paired with a compatible 2.5" HDD. The onboard UHD Graphics 630 handles display output without a discrete card, reducing platform cost for office or media systems. Virtualization technology is enabled for hardware-assisted virtual machines.

Questions about this item

Will this LGA 1151 (300 Series) processor work with a motherboard I already own that uses an Intel 300 series chipset?

Yes, the Core i3-8350K is compatible only with motherboards based on Intel 300 Series Chipsets and uses the LGA 1151 (300 Series) socket.

How can I verify the integrated Intel UHD Graphics 630 is active after installing the CPU?

The integrated graphics run at a base frequency of 350 MHz and can reach a max dynamic frequency of 1.15 GHz; check Device Manager or BIOS to confirm Intel UHD Graphics 630 is detected.

Does the OEM tray version of the Core i3-8350K include a cooler or do I need to buy one separately?

The OEM tray version ships without a boxed cooler; a separate CPU cooler for the LGA 1151 socket must be purchased.
