Review on Ultimate Performance with ASRock B550M PRO4: Unleash the Power of 3rd Gen AMD AM4 Ryzen and Future AMD Ryzen Processors by Jay Meza

So I bought it from MicroCenter in mid-June and I can say that this motherboard is a great option if you want both good internal connections and a good rear panel. /O. This $115 motherboard is a great buy. VRM is the board's only weak point, but if you don't overclock the 3900x/3950x much, this board will work just fine. I have a standard 3900x and it works great. The BIOS is also good, if clearly average. One thing I liked (which others might see as a downside) is that many MSI boards don't have an "Auto OC" feature that automatically overclocks your CPU. If I ever overclock I always prefer to do it manually so I appreciate not having to disable this feature. the options are contained in the AMD Overclocking menu. Another little-advertised benefit of this board is that an additional m.2 SSD slot shares lanes with two SATA ports; This means that if the additional m.2 slot fills up, you'll lose the ability to use two of the six SATA ports. This is actually a good thing since most other motherboards' secondary m.2 slots share lanes with the bottom x16 PCIe slot, meaning you'll lose access to it, while this board avoids this issue by removing the Split tracks into two SATA. ports instead. I really like that I can use the extra m.2 slot and the bottom x16 PCIe slot at the same time. 5/5!
