There are 3 RGB headers on the board. With a Y-cable you can also control 2 fans via one connector.

The board already has a newer bios that supports Ryzen 3000. However, I have installed an even newer bios on my board. Everything runs top. Bios version E7B85AMS.1B0

Hello I needed a BIOS update for my mainboard. However, this is not a big deal, as the BIOS of this mainboard can be updated even without a CPU update. You just need a USB piece with the BIOS file on it.

Hallo, du kannst den bios selbst installieren wenn nötig. Dies steht in der Spezifikation: „Flash BIOS Button: Simply use a USB key to flash any BIOS within seconds, without installing a CPU, memory or graphics card.„ https://www.msi.com/Motherboard/B450-GAMING-PRO-CARBON-AC/Overview

Only M.2. You can connect your 2.5 SSD to the MB but not install it.

There are 2 variants: 1) Buy to benefit "only" from more space and ports. 2) Wait for the new generation or switch to the Threadripper. Generally it won't be faster, the board has more than enough connections for fan / RGB. Maybe someone will pay something for the old motherboard... I would say yes

Yes, I have it paired with my Ryzen 3700x.

Unfortunately, it does not. You have to download the bios file from MSI's website and use flashback button on the board.

It should work perfectly. In normal operation, you can even get up to 3950X.

I don't know why it shouldn't be compatible... I also have this MoBo, but with a Samsung SSD M2, which is awesome!

The mainboard supports up to DDR4-4200, everything below DDR4 is possible. RAM configuration is mainly dependent on the processor. What processor are you using? I myself have installed folgenses on this board: Processor: AMD Ryzen 5 1400 (4, AM4, 3.20GHz) RAM: G.Skill Aegis (2x, 8GB, DDR4-3000, DIMM 288)

The 144Hz is possible via HDMI and DP but the screen must be the right one as well as the cable. Here is a report about it. https://www.google.com/amp/s/praxistipps.chip.de/144-hz-bei-hdmi-geht-das_51230%3flayout=amp
