  • Great board
Style: B550M DS3H AC
Gigabyte products never fail to impress. This experience has been no different. It paired nicely with a Ryzen 5 5600X and 64GB DDR4 3200. I replaced the WiFi AC card before I even installed the CPU. Picked up an AX210/BT5.3 card for about $20 on Amazon as well. Everything went great, running everything I throw at it with great speed and efficiency. Dances circles around my old Ryzen 7 2700X on an X470 motherboard, yet it's only 65W. Great purchase. Another satisfied Gigabyte customer. Having 2 m.2 slots is also helpful! To upgrade the WiFi card, simply remove the two screws securing the mounting bracket from the bottom of the motherboard. Swap cards, and reinstall. It’s quite easy to do. ... show more

  • Still good, but does NOT Support PBO, Auto Overclock. No RGB Fusion 2.0 pin headers. BE WARNED
Style: B550M K
This motherboard is actually not bad per se, but they didn’t at least state that it doesn’t support PBO, Auto OC in the product description, and Amazon is false advertising in the description that it supports RGB 2.0 when I cant find the pin headers on my motherboard nor could I see it in the pictures listed by Amazon. Very weird 😂, still works though. Still a good quality motherboard for the price. Easy to install. Supports the 5800x 3D as well, which is the next cpu I will get in the future. ... show more

  • Good board
Style: B550M DS3H AC
This board is a good one except it wasn't the version mobo I was expecting... However not the customers fault seeing that the version or revision number dkr the board wasn't on display so the customer wouldnt have known... Aside from that all is perfect and works great... No complaints.... And yes it does come 5000 series ready without any bios update.. Thank God considering the Q flash button wasn't on thi version of the board an I only had one processor lol 😂 but as I said its a great board for the price. ... show more

  • Seriously...just...DONT.
Style: B550M DS3H AC
My wife's daughter's lenovo legion tower 5 went kaput, so I decided I would pull all the parts from the tower and replace all, keeping the tower for matx availability and slightly less expensive build. Original build was as follows: Gigabyte b550m DS3H Rev 1.7 mobo Ryzen 5 5600x CPU GeForce RTX2070 super GPU existent ssd Existent memory Went through every troubleshoot known to man and 6 certified technicians. They all knew gigabyte was a headache for people, and they figured it might be a bios issue (even though Rev 1.7 shouldn't need a bios qflash for the cpu of choice). Then we bought new ram modules and GPU in order to avoid no display bios qflashing. Switched to appropriately sized ram modules and a GeForce RTX 3060. All items confirmed compatible. Then we honed in on the fact that when we turned the computer on after connecting, all fans and lights would start up no problem, but motherboard power went into idle, AND won't shut off with a power button long press and hold. This is a sure sign that the motherboard is already messed up from the beginning. Other reasons not to buy this board or any from their brand... I have been in multiple discord groups, facebook groups, and reddit groups/threads, all with people complaining of the same issue, and nearly all of them fixing it by returning the board due to terrible installation instructions, worse bios flash instructions, and overall headache of boot issues and crashes. I did troubleshooting on this board for 6 hours a day average for nearly 10 days, including all my research time, and if i didn't care about getting my money back for another board, going with MSI, then I would climb to the top of a cell phone tower like I used to do for work and Frisbee this thing as had as I possibly could into the nearest high traffic interstate. Gigabyte is by far the absolute worst board I have ever encountered for being user friendly, instructions friendly, or ANYTHING friendly. Seriously just DONT GET THIS BOARD or ANY of their boards EVER. Pay a bit more money and get the good stuff. ... show more

  • Exactly What You'd Want From a Budget Board!
Style: B550M DS3H AC
I'd say if you're on the fence about getting this, this is a sign to just do it already! Pretty good value for money and it is in fact Ryzen 5000 series ready as stated on the box! Great product.
