Frequently Asked Questions
Which chipset is best for the i5-8400?
For most buyers, B360 or H370 is the best fit because both support the processor without charging for CPU overclocking features you cannot use with its locked multiplier. B360 is often enough for a gaming or office build, while H370 may provide more USB, PCIe, and storage connectivity. Choose Z370 or Z390 if you need specific premium features, stronger expansion support, or a path toward an unlocked Coffee Lake processor. Otherwise, the extra cost may be difficult to justify.
Can I use the i5-8400 on a Z370 motherboard?
Yes, a Z370 motherboard officially supports the i5-8400, provided the BIOS version supports Coffee Lake processors. Check the exact model’s CPU support page before purchase, since early production boards may require a firmware update. The Z370 chipset does not let you overclock the i5-8400’s locked multiplier, but it can support faster memory settings and often includes better power delivery or connectivity.
Will an older H110, B150, or Z270 motherboard work?
No. Although those boards use an LGA1151 socket, the i5-8400 requires an Intel 300-series chipset. An H110, B150, H170, Z170, B250, or Z270 board is not an officially compatible choice. A BIOS update cannot normally turn those older platforms into Coffee Lake systems, so do not rely on socket compatibility alone. The socket may look familiar, but the electrical requirements are not interchangeable.
What RAM should I buy for this processor?
Choose DDR4 memory, ideally as a matched dual-channel kit. For most systems, 16GB using two 8GB modules is a practical starting point, while 32GB is useful for heavier multitasking, content work, or longer-term capacity. DDR4-2666 aligns with the processor’s official memory support. Faster kits may work on some Z370 or Z390 boards, but they are not essential for normal i5-8400 performance, and lower-end chipsets may run them at a reduced speed.
Do I need a graphics card with the i5-8400?
The i5-8400 includes Intel UHD Graphics 630, so you can use the motherboard’s HDMI or DisplayPort output for basic desktop work, provided the board includes the output you need. Video outputs do not function through the motherboard when a processor model without integrated graphics is installed, so confirm the CPU model carefully. For modern gaming, 3D design, or GPU-accelerated applications, add a dedicated graphics card. Also check the motherboard’s rear-panel connections, because some boards include only one display output or omit video ports altogether.
