Nice to Look at, Good to Hold. If you Can find One, Consider Sold. 9/24/2020 11:25:14 PM

Pros: - Most Awesome Mobo to me in the world, as of 2020. (^_^)
- 14 Power Phase Design, Digi Power, Dr. MOS.
- Supports DDR4 4733+ (OC)
- 7.1 CH HD Audio (Realtek ALC1220 Audio Codec), Nahimic Audio.
- Dragon 2.5G LAN.
- Unbeatable Heatsink Armor, my M.2 SSD and entire Mobo temps are kept below 40DegC.
- Refer to picture for Temps.

Cons: - All functions & features of this Mobo are nothing without full drivers & utilities installation from given Installer DVD. No DVD Drive, No Life... (-_-)
- ASRock App Shop offers some useful Apps such as ASRock Restart to UEFI & ASRRGBLED.
- A-Tuning App is not as favorited as compared to Ryzen Master. (For Ryzen CPU tuning)
- BIOS does not set XMP profile correctly. Had to perform manual settings.
- Nahimic 3 utility is down/out after sound adapter drivers auto updates. (As of writing)

Overall Review: - If you're a Singaporean like me, buy from Newegg.com cos Newegg.com has the best offer & stock right now! Nothing much is available locally.
- My PC sits in an open room at Singapore's average temp of 32 DegC 24/7/365.
- Please include an ISO image of Installer DVD Disc in ASRock Support Webpage.
- With a complete installation from Installer DVD ISO, my ASRock B550 Steel Legend now purrs like a kitten. (^_^)

Only if you really must... 9/15/2020 7:24:28 PM

Pros: Beautiful board! Color scheme worked well for the white/black stormtrooper build I just finished. Duel M.2 slots, plenty of USB, has ARGB, fairly compatible with a wide range of memory...which leads me to the cons..

Cons: This board gave me an instant headache right out of the gate, the dimm slots are SUPER picky, I had to re-slot the ram a few times to get into bios. Once I had it all together and enabled XMP, I set the speed to 3600 as well, seeing as it's for a Ryzen 5 3600, and they advertise the board being able to handle well beyond those speeds, I thought it wouldn't be a problem at all. Not the case at all unfortunately. It became quite unstable to the point where I had to turn it down to 3000, which is just sad frankly. Even worse, was the customer support I received when I called Asrock to try to ask why it won't allow me to clock to those speeds, they not only acted as if I was committing a crime by clocking that high, but I got hung-up on at one point because of a communication barrier from the operator...it sounded like he was in a tin can while talking to me... As this isn't the cheapest of B550 boards you can get right now, it's sad that the Polychrome RGB program doesn't even work correctly to the point where they had to give you all of the rgb options/setting in the bios..which honestly works best so don't bother with the software. Don't bother with the Dragon software for your bandwidth monitoring either..as in my case it couldn't figure out what is going on and would throttle the program or browser I was using at any given moment...I'm sure there are a few more things I'm missing but I just can't remember at this point..

Overall Review: Overall, if you can get past the fact that this board will almost certainly give you problems in the beginning, of some kind at least, and this isn't your first build, I'd say this isn't the worst board out there, if you absolutely must have this one for it's color-scheme and such. However, you're much, much better off with another board in my opinion. The customer support interaction I had alone was enough to keep me away from Asrock as much as possible from here on out...pretty disappointing.

Dissapointed 9/11/2020 6:05:31 PM

Overall Review: Loved everything about this board until the RGB software just won't work. Every time I open the app it freezes my computer and never opens. And to top that off if you go into the app code this board isn't even listed. Kinda ruined my build cause now I cant sync all my lights

Nice looks, but bad USB drivers 9/11/2020 8:25:09 AM

Overall Review: I really wanted to like this motherboard. I like the color, the layout, and design. But this motherboard gave me trouble in the form of a "phantom" USB device continually connecting and disconnecting, over and over and over! It would even play that sound in-game. I know what you might be thinking, that it was a bad port, or a peripheral that was faulty. Long story short, a licensed computer repair store found that the Asrock B550 Steel Legend can have bad USB drivers, and theres no known way to fix it. Asrock knows this, and they have no updated drivers to fix this issues on the boards that have it. Would not recommend this board, as you may spend more time completing RMA's and dealing with shipping returns than having a bug free motherboard, as promised.

super irritating 9/5/2020 5:21:13 AM

Pros: i honestly love the look of this motherboard. its super awesome looking.

Cons: doesnt work.

Overall Review: i received it dead on arrival. my buddy and i tried different cases and power supply cords to test it and it just would not turn on. the only thing that would turn on is the rgb lights. I was super excited when they turned on too and then sat here pressing power buttons, trying to switch around cords, thought i might of had them in backwards, everything. and my buddies and i are pretty familiar with computers we all build our own. this is just stupid and i am just so irritated. i spent hours putting this thing together and taking it apart and reputting it together again trying to get it to work.

GREAT BOARD 8/30/2020 7:44:19 AM

Pros: I'd never had such an ease of set up as this board. especially with the post codes took alot of guessing and minimize troubleshooting makes this a great value for money board! I am confident this board will last me until my next system.

Cons: None so far. Everything seems to work as it should!

Overall Review: I will recommend this to anyone who is looking for a new board.

Feels Premium for a B550 board 8/28/2020 3:03:10 AM

Pros: - Premium feel from the packaging
- it includes a a velcro which is ver neat for cable management

Cons: - hard to use the xmp profile at first but updating the bios fixed it (this should be a con who only has this as a pc)

Overall Review: It's a good motherboard and will most likely buy it for another build! That RGB looks really good too but I think they should fix the software for it.
