I had to flash the BIOS before it worked with my CPU but it was easy. Once you download the new BIOS from gigabyte's website put it on a FAT32 formatted USB stick and put it into THE WHITE USB SLOT on the back, ONLY that one. Do not use the Blue or Red or Black USB. You can only flash from the White one.
Press the Q-Flash button and wait (ages). When it's done you can use the machine! I was told to do this with no CPU or RAM plugged in but I had both and my GPU (PC fully built), it still flashed with no apparent issues.

There are many features built in.
PCIe 4 support, 2 x M2 SSD slots including a fast one for your system drive, All the B550 bells & Whistles for the latest 5000 series AMD CPU's, Revamped pretty and extensive easy to set up Gigabyte BIOS with the built in BIOS flash from USB memory stick (without the need for plugging in Graphics card keyboard HD etc.), decent sound quality etc. etc.
The downsides are few (but could be significant if you need to add any PCI expansion cards)
The big drawback is that with a dual sized graphics card the 2 spare slots on the motherboard are obscured and so unusable. (e.g. no PCI sound card can be added). It should also be noted that some of the older AMD socket AM4 CPU's aren't supported by AMD's B550 chipset.
Other than the minor limitations above this motherboard is up to the usual high quality Gigabyte standard and is a great board for an easily overclockable Windows 11 build which I would have no hesitation using again. (NB review based on Amazon price of £72.99 in early 2022).
Was preferably after mATX board and this fitted the bill. Had to enable XMP in BIOS allow 3600MHz memory to run at stock speed.
No issues installing the motherboard into mATX case, CPU, 500gb nvme and 2x8gb memory all working as expected. 3070 FE GPU was installed later, but again no issues there.
Not messed about with any CPU overclocking and based on the motherboard it's probably worth looking at more expensive boards if that's your thing, although I might have at look at the memory settings at some point but for now everything running at stock.
Typical that Amazon drop the price of the motherboard a few weeks after my build is complete and outside any return date, but other than that happy with purchase.
