    Great for Overclocking

    I have been using this motherboard since August, and it has been serving me very well! It allows me to do a stable overclock to 5ghz on my 5800XT processor, and has a multitude of features that are quite useful. I bought this for around $90 back in August, and for the price, it's great value. It's got good connectivity, with many USB ports. Overall, it's a great product. One more thing: Asrock has the best customer service, especially concerning warranties and it doesn't leave you out to dry like Gigabyte or Maxsun.

    Good inexpensive motherboard for AM4 build.

    I picked this up as new, and you could tell from the packaging it was. I had to return a version that was labeled on good condition.This purchase was for an older processor and it needed wifi. Fortunately I had no wifi issues this time. The board is solid and the build didn't have issues.Be aware of the board's limitations. There is only one m.2 slot for ssd's. If you plan to use an APU be aware it has HDMI, no display port. There is no Bios flashback button so check the website to be sure your processor is supported, otherwise you'll need and older processor to update first. If you aren't usi

    Works fine

    First one came with a wifi antenna cable unplugged and I had to return it -- Replacement has been working fine for 2+ months withfully loaded memory (all 4 slots) and 2 GPUs ... nothing to complan!

    The worst consumer motherboard I've ever used.

    So, firstly, the UEFI backup battery is ‘not replaceable’. When I first saw that on the box I thought it was a sticker that was meant for a different product that got mixed up at the factory. I assumed that is was actually meant to be just a generic warning label about lithium CR2032 batteries and how swallowing them are dangerous or alike.Guys… They actually tried to make it non-replaceable.They glued a chunk of rubber behind the small metal spring tab that keeps the battery in the holder in an attempt to facilitate such an end. For what reasons, I haven’t the faintest clue.Secondly, correct

    If you need Front Case (USB 3.2 Gen 2x2 - Type-C) or USB-C(U32G2X2_C6), look elsewhere.

    [REAL REVIEW]Comes with a modern BIOS & supports CPUs as late as the Ryzen 5700X, will work on all Ryzen CPUs OOTB. This is a MOBO comes from when USB-C wasn't that common, so if your front USB header relies on USB 3.2 Gen 2x2 - Type-C you will have no working USBs in your front case; Consider another case.Wifi module is also pretty bad if you're not using 5GHz, 2.4GHz used 20-40mbps of a 500mbps maximum speed resolved by using 5GHz band. If you use LAN you are unaffected by this change.Probably has the best BIOS in the industry, very modern.MOBO is surprisingly small, will not fit a cooler bi

    Simple, stable board for simple, stable use cases

    Used this board and a Ryzen 5500 to assemble a very inexpensive dedicated folding rig. It's not fancy, it doesn't include a bunch of overclocking capabilities, however it's absolutely fine for a simple and capable setup. It's now running a 4090 and a 4070 Super under Fedora 42. When the GPUs are at idle, the system consumes about 45W at idle, about half of that is the GPUs themselves even at idle.If you need an inexpensive, non-frivolous Zen 3 board, this will fit the bill just fine.

    Great budget MB - update to latest BIOS!

    EDIT: updating BIOS to 1.20 enables default XMP (3600mhz) to now post and work. Do update if you're having any issues. B550 is a new range so giving ASrock the benefit of the doubt.Great budget B550 motherboard which suits my build fine. Paired with a Ryzen 3600 and Vega 56. Enough SATA and USB ports for my usage. Note that the WIFI version has less SATA ports.Do watch out about RAM and XMP combability though - my Corsair Vengeance RGB Pro (CMW16GX4M2Z3600C18) doesn't boot with the XMP (3600mhz) profile on; at the time of this review (latest BIOS installed 1.10). There's a beta bios (1.10A) ou
