from completed build (GPU Update): A Taste of Red

I decided on this motherboard primarily because of its styling, but also for the spacious placement of the components, plentiful USB connectors, and future ability to upgrade. The BIOS is stylish and easy to use, although I had to update it for it to properly acknowledge my Team Dark RAM and run it at a full 2933mhz instead of the stock ~2100mhz. 5/5.

A decent motherboard for the price. I wanted to be able to overclock my CPU and not break the bank.

This board performs pretty well. It looks awesome and has no problems with the RAM. It does have some glaring issues though that require me to give only 3 out of 5 stars:

1) It is not a full size ATX. The last column of standoffs aren't used, so the RAM, 24-pin, and USB cable are unsupported by the chassis. Makes installing them nerve-wracking (place a finger underneath the board for support).

2) Cheap, flimsy I/O plate with annoying tabs.

3) UEFI 2.6 CPU temp reads 20 C above the actual temp, and UEFI 3.1 reads +30 C! This screws with fan profiles and makes things inefficient. Hopefully ASRock gets their act together with a future BIOS update. For now, stick with 2.6.

Sleek and built with Ryzen in mind.

Really good budget mobo. It is pretty decent for overclocking as well but only if you update the BIOS to it's latest version.

I have no complaints, as this is my first build, but it's nothing fancy. I'll buy a higher-end board at some point.
