Unfortunately, we do not offer this exact antenna as an individual part in our range. I would recommend that you ask the manufacturer directly about this or possibly buy another aerial as a replacement.
Of course the board has Gen5 M.2 slots, always trust the manufacturer's specifications and not those of the seller.
The Gen5 M2 is connected to the CPU M.2 slot (the top M.2 slot) and therefore has the full bandwidth, a second Gen5 M.2 makes no sense, as it is only connected via the chipset and therefore does not have the full support of the CPU.
The revision number is not specified in your in-house product data. According to the official Gigabyte website, there are both rev. 1.0 and rev. 1.1 versions of this motherboard, each with its own support page and documentation. To confirm which revision you have, check the physical board for a printed «REV: X.X» label, typically located in a corner of the PCB. If you need to download drivers or BIOS updates, always select the correct revision to ensure compatibility.
The motherboard officially supports the AMD Ryzen 7 9800X3D processor from the first BIOS version (F1), as can be seen on third-party compatibility lists. According to the official Gigabyte website, the processor is compatible, but it is recommended to install the latest BIOS version to ensure maximum stability and compatibility.
You can therefore use the processor directly, a BIOS update is not absolutely necessary, but recommended.
The maximum speed of the SSD is determined by the mainboard's M.2 PCIe (4x) interfaces. This mainboard supports M.2 PCIe 4.0 SSDs, which can theoretically achieve transfer speeds of up to around 7000 MB/s. It has four M.2 PCIe 4.0 slots, which enables fast SSDs with very high data rates.
Yes, you can set the BIOS of the X870E AORUS PRO ICE to German. The BIOS user interface supports several languages, including German.
You can usually find the language settings in BIOS settings under a menu such as "Advanced" or "Settings", where you can change the language to German.
Although they are very similar, there are some differences, such as the wireless network card, which is better on the X870E. It has an 80A smart power stage compared to 60A on the X870, which can be useful if you overclock.
If you are going to use it as is and don't care about overclocking, the Gigabyte X870 A ELITE WF7 ICE AM5 ATX MB will be a good choice for the price.
