}Frequently Asked Questions
What does the 'F' mean in Intel Core i5-10400F?
The 'F' suffix means the chip does not include integrated graphics (iGPU). The Core i5-10400F requires a dedicated graphics card to produce display output. The F-series is typically priced lower and is ideal for builds that will use a discrete GPU.
What socket and motherboard chipset does the Intel Core i5-10400F require?
The Core i5-10400F uses the LGA 1200 socket and is compatible with Intel 400-series (H410, B460, H470, Z490) and 500-series (H510, B560, H570, Z590).
Does the Intel Core i5-10400F support DDR5 memory?
The Core i5-10400F supports DDR4-2666. Maximum supported memory is 128 GB across 2 channels.
