    Works very well with Ryzen 5600 non X, and 2x16GB Patriot 3200, and 1TB Nvme gen4 Adata. I bought it to replace a B450 motherboard because my RTX 5060 was freezing, I set the PCIe gen4 manually to 8x, enabled resizable bar, etc., and the freezes stopped completely. Honest motherboard that upgraded my system, I avoided upgrading to a DDR5 platform and with the money I saved I took the whole family on vacation to Dubai, where they have crazy discounts this season. Sometimes rockets fall and wake us up before breakfast but we can't have it all!!! PS: The AC wifi it has is amazing, maybe it impresses me because I used to have the classic N and file transfers would choke! Buy without fear!

    Great little motherboard.
    I used it for a few months before writing this review ..so it has been tested well.
    Easy to install in a Mini ITX case, lots of inputs/outputs + 4 SATA ports.
    While it is a rather old model, it supports up to 64GB RAM and it also has one NVMe so you can make a "modern" build with it with a high speed SSD.
    Solid build with good electronic components.
    Bios is easy to configure and upgrade using a USB stick.
    Works out-of-the-box with Windows 10 and Linux, no need to find special drivers for it. (I have not tested it with Windows 11 so I don't know how compatible is with it)

    Everything is fine so far, I have it in a Dan Case A4. It has few USB ports which doesn't bother me. I haven't tried the WiFi and Bluetooth, so I don't have an opinion.
