Questions about AsRock B650I Lightning WiFi AM5 mITX HDMI DDR5 retail

Overclocking is complete nonsense. It just needs a lot more power and you risk the PC dying after a short time...

The Ryzen 7900 can be used on the B650I Lightning WiFi as the board supports AMD Socket AM5 processors, which includes the Ryzen 7000 series. The performance of the board should be sufficient for the Ryzen 7900, as it has an 8+2+1 power phase configuration with Dr.MOS, which ensures a stable power supply. However, problems can occur when using XMP (Extreme Memory Profile), as reports of BSODs and errors show, especially when unsupported RAM configurations are used. It is important to check memory compatibility and use the recommended memory modules.

You can install one M2 NVME at the front as usual. The second M2 NVME is mounted on the back of the mainboard. You can see this directly in the video at around 1:30 minutes: https://www.youtube.com/watch?v=9vfeZxitjp8

Yes, I installed it with Windows 11.

If you see the drive while within the BIOS, but not in the installer, ensure the bios is in UEFI mode, and also try disabling CSM. Worst case you need to load storage drivers downloaded from AsRock site during install from a different USB, or copy them to the one you're using to install Windows. Hope that helps.

Yes, the AXP-90 X47 CPU cooler is compatible. Ryzen 9 7900x and 7950x 170w cpus are not recommended for this motherboard, they work but not at full capacity. Take DDR5 EXPO RAM (7200mhz didn't work for me) this one works for me:Corsair Vengeance RGB AMD EXPO (2 x 16GB, 6000 MHz, DDR5 RAM, DIMM) If you don't see a bios image the first time you start up, you need to remove a RAM strip and reboot, then enable EXPO in the bios.
