## Questions & Answers

**Q: Is this compatible with the amd ryzen 3 2200g**
A: Yes it is... That's the setup I have in my pc

**Q: Will this work with ryzen 7 3800x?**
A: It will work, but this is a low budget motherboard with basic VRM, so kind of will limit what you can do with a high end CPU.  I wouldn't go higher than a 3600 with it.  If your spending the money on a 3800X then get a better board.

**Q: Is it compatible with Ryzen 3 1200?**
A: yes

**Q: Would this fit a darkflash t20?**
A: Yes, this will fit.
