Which CPUs does the X870-P WIFI support?

It uses the AM5 socket and the AMD X870 chipset, with Ryzen 7, 8 and 9 processors listed as supported. That covers the current AM5 desktop generations.

How much memory can I install?

There are four DIMM slots, and the board lists support for speeds up to 8000 MHz. Higher speeds depend on the memory kit and the CPU's memory controller.

Does it have Wi-Fi built in?

Yes. Wi-Fi is part of the board's name and specification, so no separate adapter is needed.

Is this board good for overclocking?

It is a PRO series board, not an MPG or MEG model, so its power delivery is aimed at standard builds rather than heavy overclocking. Mild tuning is fine; extreme overclocking is better served by MSI's higher tiers.

The listing covers the motherboard itself. Check the box contents for cables, Wi-Fi antenna and documentation before building, since bundles vary by model.

How does it compare with the X870E boards?

X870E boards generally add more PCIe lanes and connectivity. The X870-P WIFI covers the core platform features for most gaming and work builds at a lower tier.
