Frequently Asked Questions

Does the Core i7-4820K support DDR4 memory?

No, the Core i7-4820K only supports DDR3 memory (up to 1600MHz officially, though higher speeds may work with XMP profiles). It uses the LGA 2011 socket and is designed for X79 motherboards, which only support DDR3.

Can I overclock the Core i7-4820K?

Yes, the 'K' suffix indicates an unlocked multiplier, allowing you to overclock the CPU easily. With adequate cooling, you can push the clock speed beyond the stock 3.7GHz base and 3.9GHz turbo.

What cooler is compatible with the Core i7-4820K?

The Core i7-4820K does not include a stock cooler, so you'll need to purchase an aftermarket cooler. Since it uses the LGA 2011 socket, you'll need a cooler that supports LGA 2011, such as many high-end air coolers or AIO liquid coolers.
