Review: Great value - Fantastic value for money ! Great starter motherboard for anyone looking to get into PC's. No mvme support but thats a trade off I was willing to take . Be careful of the size of your GPU due to it being a smaller sized board . Overall impressed with this , overclocking feature too which is rare to see at this price point.
Review: Cheap and Cheerful - Used this for my first ever build thanks to some great reviews on youtube, good compatibility, Bios was updated to ver 3.9 so didn't have to update it before installing my Ryzen 5 3500x. For compatibilty check the ASRock website, great exhaustive list of usable components and which version of Bios needed Bit of a no frills board, minimal connections but should be fine for any standard build. No integrated RGB controls if you want that from your Motherboard as I said it's bare bones offering, just giving you the essentials

## Questions & Answers

**Q: Will this motherboard support a ryzen 3400g out of the box without any bios updates?**
A: Yes but depends on the build of Windows 10 you are using.  I found they aren't stable until Windows update 2004 has been installed.  If your version of Windows 10 is older, install it, activate it, go straight to google and look up Windows Download Assistant.  Follow the links from Microsoft's website (ensure it is microsoft). This will install the assistant program on your pc and download the latest updates only so you don't have to wait for Windows Update to go through the motions.  Once 2004 update is I've found it completely stable.
As for the board, there were no BIOS updates available at the time I purchased these, and I've had a few of them now, so the intermittent fault that locks windows up and makes it reboot could only be fixed with the windows update.  Other brands of boards have had the same problem.
Hope this helps.

**Q: Will this work with a RTX 2060?**
A: Yes, it will work with any graphics card from the last 10+ years and for at least the next few until they replace PCI-E as the slot type.

**Q: what is the bios update and would it support a ryzen 5 3400g without a bio update?**
A: You won't need a bios update. The 3400g is a Zen+ 1st gen Ryzen. This board has supported the never 2nd Gen Ryzen out of the box since at least January (when I bought it)

**Q: Does the screws for the board come in the case ?**
A: Yes
