Frequently Asked Questions
Does the Intel Core i9-13900K come with a CPU cooler?
No. This retail Raptor Lake chip ships without a fan, so you need to buy a separate CPU cooler. With a 125W base power rating, a high-end air cooler or AIO liquid cooler is a sensible choice.
What motherboards are compatible with the i9-13900K?
It uses the LGA1700 socket and works with motherboards built on Intel 600- and 700-series chipsets. A 600-series board may need a BIOS update first, so check the motherboard maker's CPU support list before you buy.
Can I use DDR4 memory with the Core i9-13900K?
Yes. The processor supports both DDR5 and DDR4. Your motherboard decides which one you can use, because each board supports only one memory type.
Can I run a display without a graphics card?
Yes. The i9-13900K has Intel UHD Graphics 770 and supports DP 1.4a, HDMI 2.1 and eDP 1.4b outputs. It is fine for desktop use and troubleshooting, but demanding games still need a dedicated GPU.
