The board being discussed is the one my friend is considering switching to. He’s upgrading from a 1600 to a 3900X and is concerned about Adobe applications like Premiere struggling with 4K rendering on his CPU. There’s worry about the VRM’s ability to manage a chip that draws over 150W. A TechSpot review of a similar board suggests keeping the CPU at its default speed, which aligns with what we’d recommend. I’m curious if others have attempted similar changes and seen any results.
B450 is compatible with 3900x, but I suggest considering B550 or x570 for better options.
Discussing BIOS compatibility isn't the focus. Asrock's BIOS is compatible with Matisse CPUs. The emphasis is on the board's power delivery handling high current.
Similar to the article shared, b450s can manage 3900x; however, I suggest opting for X570 or b550 since they offer more powerful VRMs and better power delivery.
Based on the tier list provided, I wouldn't risk my investment on this motherboard running the R9 3900X without problems. The list suggests an R5 3600 is the top choice for compatibility. You might face stability challenges with higher models like the 3600 or 3600X, especially if you go beyond the 3600. This recommendation falls under the 'Tier E' section.

Isn't this just discussing the overclocking capabilities of board VRMs? The same article I linked showed zero issues with an octacore on the board.
Many users experienced performance problems, especially freezing, when using less powerful chipsets. If the motherboard is limited to an R5 3600 with a default TDP of 65 watts, handling the 3900X—even at its standard 105 watts—seems unlikely. This highlights a significant gap between expectations and reality. It's your decision to purchase it, but be aware of the potential risks involved.
