Review: Good Durable motherboard. - Very sturdy motherboard, good VRM cooling, ample of ports and good audio (nahimic), and has internal slot for wifi/bluetooth combo card. Warning for pairing with newer AMD cpu "Cezanne" like 5500,5600 etc. MB has BIOS version 2.10 and will need to update to latest BIOS 2.30, and these newer cpu CANNOT be used to update BIOS, it was sheer luck that I had 5600x which was tranferred from the other system to update the BIOS. From the official support page : To support Ryzen newer 5000 and 5000G-series processors, it requires to update the BIOS with Matisse, Renoir or Vermeer CPU. Other than that, I am happy with the product performing as well and have had no issue while testing under heavy load on both CPU and GPU.

### ⭐⭐⭐⭐⭐ Good motherboard for ryzen 5 5600x
*by S***O on 24 January 2024*

Good quality motherboard,overclocking quality good , argb lights soo beautiful

### ⭐⭐⭐⭐ Good motherboard but no bios flashback
*by S***S on 29 December 2021*

Bios is outdated. 2.10. If you're getting a 5000 cpu then you'll need to update the bios which requires a older generation cpu since it doesn't have bios flashback. So just keep that in mind.
