    Nothing wrong with this, but the support for this mobo is unbelievable. The issue is that I couldn't set my ram to its advertised speed even with XMP profile on and I couldn't change the ram voltage for some reasons. I emailed Asrock a week ago and haven't heard back and I couldn't find anything online. Another thing to keep in mind, if you are using a m.2 ssd, the bottom m.2 slot is the only slot that supports that, the top slot is for Nvme.

    So I didn't want to deal with the possibility of my CPU not booting with a B350 motherboard due to an outdated bios needing flashing with the 2nd generation Ryzen CPUs. Being that the only extra CPUs that I have laying around are old AMD Athlons I decided to go with a B450 motherboard so that I wouldn't need to worry about any compatibility out of the box with Ryzen 2nd gen CPUs. No I wasn't going to deal with an AMD boot kit as I need to have things instantly! I am very disappointed with this ASRock bios as it is not very feature rich. I am also very disappointed with the memory compatibility which I will get to under the memory review. I hope that future bios releases will up the features of this bios and expand the memory compatibility.

    Think it looks cool. Not sure about the VRMs and stuff but allowed me to overclock my Ryzen 5 2600 to 4.1 Ghz at 1.3625v. Has all the ports and stuff I need. No RGB, which i appreciated.

    great little board that does everything I need it to do. as of Oct 2019, still gets regular BIOS updates from ASRock. has 2 M.2 slots, 1 of which is NVMe, the other operates at standard SATA3.0 speeds.

    Not budget, but not high end and does everything very well. Has lots of fan headers and has amazing VRM cooling for great OC's.

    Nice AM4 motherboard. Definitely worth it if you can get it on sale for around $65. It's also got some nice features that other micro-ATX B450 boards don't.

    Great board, a lot of good features, good VRMs, four ram slots. If you're going B450 and micro ATX, this is the go-to board.

    So far, so good. It's got a bunch of Fan connectors, a solid VRM, and significantly improved software from my old AsRock 970 board.

    Motherboard is perfectly functional, but the bios is horrible and it gave me the most trouble I've ever had installing Windows.
