Description

The Gigabyte B550M K (rev. 1.0) motherboard is aimed at users who want a reliable and economical solution for building a computer with an AMD processor. The B550 series is part of AMD's AM4 platform and offers good performance and flexibility for user requirements.

The Gigabyte B550M K (rev. 1.0) motherboard provides basic functions and features for operating a computer. It includes PCIe Gen4 expansion slots for connecting peripheral devices, DDR4 memory support with maximum speed, USB 3.2 Gen1 slots for fast data transfer, and an M.2 slot for a fast storage drive.

This motherboard is suitable for users looking for a reliable and affordable solution for general use, office work, web browsing, multimedia, and simple tasks. Although it does not offer the most advanced features and functions of more expensive models, it is a satisfactory choice for users seeking a basic and economical motherboard for their system.

PCIe 4.0 Design

  • PCIe 4.0 x16 slot with faster bandwidth and lower resistance.
  • M.2 PCIe 4.0 x4 slot with lower resistance.

Dual NVMe PCIe 4.0/3.0 M.2

With integrated NVMe PCIe 4.0/3.0 x4 and PCIe 3.0 x2 M.2 slots, GIGABYTE motherboards offer users the ability to connect in NVMe or SATA mode for M.2 SSD devices.

Providing data transfer speeds of up to 64 Gb/s, the dual M.2 slot design offers an ideal storage solution, while also supporting RAID functions.

GbE LAN with Bandwidth Management

The GbE LAN features a network bandwidth management application, which helps improve network latency and maintain low ping times for better responsiveness in busy LAN environments.

Smart Fan 5

With Smart Fan 5, users can ensure that their gaming computer can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard.

Not only that, but with Smart Fan 5, more hybrid fan headers have been introduced that support both PWM fans and voltage operating fans, making the motherboard more liquid cooling friendly.

Fan Stop

With Fan Stop, each fan will completely stop when temperatures drop below a specified limit. Which fan stops, based on readings from which sensor and at what temperature, all of these can be customized to your preferences.

Hybrid Fan Pin Headers

Gain complete control over your water cooling setup. Smart Fan 5 receives updated information about the flow rate through the Hybrid Fan Pin Headers, giving you absolute oversight of your computer. All Hybrid Fan Headers can automatically detect the type of cooling device, whether it is a fan or a pump with different PWM or Voltage operation.

    Initially I had given 5 stars but I am coming back and removing one star and I will explain the reason below. For simple use, the motherboard is great. I have had it for a year and it is very reliable, I have it with a Ryzen 7 5700x, 32GB 3600 Kingston Fury RAM, 16GB 4060ti Gigabyte GPU. I don't play games, just simple use. No need for a BIOS update. Okay, it only has 1 fan header but personally it doesn't bother me. It doesn't have screws but I knew that because other 4 Gigabyte motherboards I have didn't have them either and I bought screws and standoffs separately. The reason I removed one star is as another friend mentioned, the temperatures on the VRM. With the 5700X there is absolutely no problem. However, a few days ago I tried the 5950X. While it also runs without a BIOS update, under full load I had throttling due to high temperatures on the VRM. So 4 stars because it is a reliable motherboard, and I don't expect a 90€ motherboard to run a 16-core processor without problems. Someone who has higher demands from their PC and a powerful processor should go for a more expensive option, with better VRM. I didn't consider it important until I looked into it because I was concerned that the processor couldn't run properly and the answer was the temperatures on the VRM.

    The motherboard is unacceptable. The VRM temperatures are excessively high, reaching up to 110 easily, and it underclocks the processor in order to continue its operation.
    I should note that I am using liquid cooling with extra cooling for the VRMs!!
    Unacceptable product. I made a mistake trusting Gigabyte, and I should have spent a little extra money for an MSI or ASUS!
    UNACCEPTABLE!

    Really, unacceptable in gigabyte the motherboard is B550 and cannot comfortably handle the R5 5600 in games, it reaches 95-100C in VRM temperatures and lowers the frequency.
    I have Arctic Liquid Freezer III 240 black cooler (changed the fans from p12 to p12max)
    fans 4 (two p12max, two p12)

    The motherboard, if you're lucky, has half the screws. There are 4 screws missing from those that screw the motherboard. I know that normally the rest should be in the box but the box is used. So luckily my own Asus motherboard had DOUBLE the screws inside in case you lose some, and we managed. And even funnier is that it only has 1 fan header.... a motherboard from 2023 for 96 euros has ONE fan header. Never again gigabyte is a ridiculous company.

    With the morning, I remove one star as it has only one fan header + one for the CPU fan even though Gigabyte counts them as two fan headers on their site (misinformation). The only reason I didn't go for the Gigabyte B550 DS3H was the extra 10 euros and now I will have to spend it on a fan hub (or 18-20 euros to buy 2 more Arctic Bionix fans that will be connected in series with the other 4 I already have).

    Otherwise, very good quality construction for such a cheap B550. The system set up is as follows:
    • Case: CoolerMaster MasterBox Q300L Mini Tower Retro
    • Motherboard: Micro ATX Gigabyte B550M K
    • PSU: Be Quiet Pure Power 11 500W Full Wired 80 Plus Gold (upgrade)
    • RAM: G.Skill Aegis DDR4 16GB (2x8GB) 3200Mhz (upgrade)
    • Storage: Kingston NV2 250GB
    • CPU: Ryzen 5 5600G (upgrade)
    • WiFi/Bluetooth Card: Gigabyte GC-WBAX200

    Update (7/3/2023 - 1 month of use): I did a BIOS update to the latest version FC. Everything is fine without any problems. The computer starts slightly faster, like 2-3 seconds, but it might be just my idea. In case you encounter problems with memory or processor, it would be good for your first step to be this before looking elsewhere. Many times this process has saved me and now I did it because I had enough free time.

    I was a little worried because I couldn't find much information online about this motherboard.
    It fit perfectly and worked from the first boot.
    RTX 3060ti,
    Ryzen 5 5600,
    32gb 3600mhz(XMP) RAM,
    4x HDD 2TB,
    2x M.2 1TB.

    I was a bit disappointed that it only has 1 connector for fans (besides the CPU), it doesn't have connectors for RGB, and it only has 4 SATA ports instead of 6. But for a budget card with this chipset that supports 5th generation Ryzen without a BIOS update, it's good.
