Intel Core i9 9900K/KF Overclocking Guide (Page 2)

Disclaimer Overclocking your CPU technically voids your warranty. However, if you want to overclock and still be covered, Intel does provide an aftermarket overclocking warranty for about $19 located here: (PTPP). Overclocking can also damage your CPU, especially if done incorrectly. This guide is about how to overclock, but doesn't take responsibility for damages that could occur; you bare sole responsibility for any damages that may arise.

Have you Overclocked Before?

If you have overclocked before and understand hardware selection and the basics of overclocking, you should skip to the next page. The first part of this guide is for those who want to know what to do before overclocking.

Where do I start?

9900K Overclocking Guide Systems

  • Motherboard: Intel changed power supply guidelines when switching between the Z370 and Z390 chipsets, and even though both chipsets will support overclocking, you will need a Z370 motherboard or Z390 motherboard with a very high-end VRM to get out every little bit of performance. Even at stock settings, power supply guidelines are much higher.
  • DRAM: Intel and motherboard vendors have greatly improved DDR4 compatibility and speed potential, at least compared to Skylake. While we still recommend buying a kit off your motherboard's Qualified Vendors List (QVL), up to 3600MHz is a good target for easy stability. You don't need RAM that fast, but if you can afford it, you shouldn't have a problem getting it to run at full speed. Four sticks are harder to overclock than two, and if you get a four stick kit, you can't expect more than 3200MHz with ease (especially if it's a 64GB kit).You can find your QVL in the support section of your motherboard vendor's website or inside the manual (if differs by brand).
  • Cooler: High-end air coolers are recommended, but most people get all-in-one water-cooling coolers since they offer the best of both worlds. They are easy to install, safe, and perform well. Your cooling is your ultimate limitation on your overclock when you are at above-ambient temperatures, so don't cheap out on a cooler.
  • PSU: I would leave about 200-300W aside for a nice overclock on an 9900K/KF.

You enter the BIOS/UEFI by hitting "delete" or F2 (on most boards) during boot up. For most boards you have basic and advanced modes, I always skip to the advanced mode and tend to navigate with the keyboard. To enter a setting, you either type (or delete and then type), use +/- keys, or you click and scroll. Then you have to "Save & Exit" the BIOS/UEFI for the settings to apply (typically F4 or F10 key).
