Great Aesthetic, Easy setup 8/3/2020 9:44:43 AM

Pros: Beautiful motherboard, I moved on from an X370 Asus Crosshair VI Hero, paired the board with a 3600XT.

-Easy setup
-All fan headers and USBs in easy to reach places
-Excellent looks
-Integrated IO shield is more helpful than I thought
-RAM and CPU working flawlessly at the speeds I want

Cons: -Needs more compatibility RGB RAM (especially G.Skill, it's too popular to ignore)
-POST code readout needs to be in upper right corner, in the lower right it gets hidden (especially with vertical mount GPUs)
-Wish it had more sophisticated RGB software

Overall Review: I like it a lot more than my old X370, as I'm not that much of an overclocker, this board is ready for the newest AMD CPUs and looks great doing it. I'm really surprised this is a B-board, as it has everything I would expect out of an X-series. I'd recommend this board, or the Phantom or Steel Legend variants to anybody looking to get into Ryzen right now - it's in the best price bracket and has SOLID components and the only one in its range with a POST code readout. This was super helpful when dialing in my RAM.

Nice board for B550 8/1/2020 10:25:05 PM

Pros: Board is heavy and well made
VRM heatsinks are nice
No problems with XMP
Does NOT have a chipset heatsink fan

Cons: Little pricey for a B550, could get a cheap X570 at this price

Overall Review: Very solid board. I have been buying ASRock for a while and this board is no different. Wish the B550 boards hadn't been overpriced compared to X570 boards that came out earlier.

Stable, Solid and Cool looking. 7/28/2020 3:41:49 PM

Pros: Looks cool with the blue PCB
Well laid out and solid.
Worked out of the box, booted at first power up.
Stable, paired with a 3600.

Cons: I don't know of any imperfections with this board., it just worked.
I couldn't find it in stock for about a month after I decided to buy it.

Overall Review: I bought this to upgrade a Steel Legend B450. It was this or the PG Velocita (Maybe I will buy that next for a second system).
ASRock boards have always been solid beginning with the Z75 Pro 3 I purchased in 2012 from Newegg. (The Z75 Pro 3 still runs as a mining machine btw)

What a waste of time 7/28/2020 10:27:12 AM

Pros: Great job on placing the holes for securing the motherboard to the case. Well done!

Cons: I tried two of these boards with multiple different CPUs. Posts with one stick of ram. Dr Debug C5 with two sticks. Really sad because I typically have good luck with ASRock products (my ASRock TRX40 TAICHI is awesome). ASRock support is pretty poor. They basically told me to RMA it.

Overall Review: If you enjoy wasting your time this is the motherboard for you!

Manufacturer Response:
Dear Valued ASRock Customer,

We sincerely apologize for any inconvenience this may have caused you.
Please trouble shoot the mainboard whether the issue is resolved.
• Unplug the ATX power.
• Clear the CMOS (refers to user manual link: https://download.asrock.com/Manual/B550%20Extreme4.pdf ).
• Reseat the CPU and heatsink fan.
• Reseat and test with 1 x memory on each slot to verify all slots are working. Same to the memory to test individually.
• Populate the memory if both slots and memory are working individually.
• Check the memory is on the QVL to avoid compatible relatd issues.

Great board easy setup! 7/27/2020 7:29:43 PM

Pros: The aesthetic is phenomenal , looks very good.
VRM is stout and stays warm running a 3900x
Overclocking features are great and I was able to get very tight timings on 32GB of b-die

Cons: I wish it had a cmos reset button (I wired my reset button to the cmos jumper)
integrated wifi/bluetooth would be nice

Overall Review: Easy to setup, booted right away. Great benchmark scores. Running a 5700xt, sabrent pcie 4.0 NVME drive, wireless Key E card for bluetooth, intel 660p in other nvme slot. Able to get very tight timings on b die. Love the board so far.
