    Once again showing up here is MSI. This time, it’s with the MAG X570 Tomahawk Wi-Fi. No, this one didn’t just show up here due to the popularity of MSI! However, it is an extremely popular motherboard. So much so that it’s getting hard to get one of these! Maybe that popularity is caused by this motherboard being feature-packed? Perhaps it’s because this motherboard is painfully fast in terms of gaming? Unfortunately, this will have to remain like women as another universal mystery. Either way, it’s one serious sought-after motherboard!

    The MAG X570 Tomahawk Wi-Fi starts out with Core Boost. It’s a custom power delivery system. Whatever you are rigged on for stock or overclocking, your Ryzen 9 5900X will always have the correct power. With all the thermal solutions included, you won’t have to worry about detonations after overclocking or otherwise. It’s all rigged to help keep all temps nice and low no matter how hard you’re pressing your hardware. Get the MSI Dragon Center installed and you’ll have a 1-click overclock. Finish it all off with the high-speed Wi-Fi 6 and 2.5G Ethernet connections. Yes, it’s your own fault for using a 14.4Kbps connection with this stuff!

    Despite the features and capabilities of the MSI MAG X570 Tomahawk Wi-Fi, there is a bit of a problem with its design. All the fan headers are located at the bottom of the motherboard. Thankfully this can be fixed with various extension cables. Unfortunately, that’ll be another expense to deal with. Perhaps a nice case helps?!

    Yes, there’s a hefty amount of different things to consider when buying a motherboard. Here, we’ll handle some of the questions outright. However, if you have questions beyond these, please feel free to ask in the comments section below.

    1. Why is it so important to have dual PCIe 4.0 M.2 slots?

    It’s all on the loading times. One of the main concerns of many gamers is if they’ll still be loading while everyone else is already “off to the races”! This is a really big problem in team-based games. However, if your loading times are low, you won’t have to worry about it at all. That’s what those slots, mixed with NVMe drives do. It’s massively faster compared to SSDs and HDDs.

    2. What’s with this TPM stuff?

    TMP stands for Trusted Platform Module. It’s meant to act as a hardware-based security feature. Many motherboards have a TPM built-in. With others, they’ll have a TPM header so you can install a TPM if needed. Lately, it was found out that the Windows 11 installation requires one.

    3. Why are the motherboards not updated to the latest BIOS?

    The release dates of the motherboards and CPUs/APUs are almost always going to be different times. In order to compensate for this, the motherboard manufacturers publish BIOS updates to handle newer hardware. Unfortunately, most sellers know that buyers are very interested in getting their orders/items sealed in the box. There’s no chance for the sellers to update things before shipping them out. It’s weird too since many buyers will complain that the seller could have updated the motherboard before sending it.

    4. Why are all these motherboard ATX?

    The form factor is only one part of it. However, when you’re considering that the Ryzen 9 5900X is the CPU in question here, smaller might be a problem. The problem is the heat. Ryzen CPUs/APUs are known for heating up quite a lot. Yes, others do the same. However, the method to make things immediately worse is trying to run them in small spaced situations. Even though some smaller form factor motherboards can use the Ryzen 9 5900X, heat becomes a bigger problem.

    5. Can these motherboards handle Virtualization Technology (VT)?

    Yes, they can. The trick to it is to look up the names used. With Intel situations, more often than not, you’ll be looking for that particular name VT. AMD situations also have it but on many occasions simply re-named it. This is why you have to look things up for each motherboard you’re dealing with. Just note that VT is mostly used for emulation. So if emulators are among your target uses, you will have to enable it. On many occasions, it won’t be enabled by default in your BIOS. Again, don’t forget to flash update your BIOS when getting a new motherboard.
