It says in the specifications that the motherboard has Pcie 2.0 built in. That is surely not true, as the predecessor already had Pcie 3.0 slots. So what does this motherboard really have? 4.0?

According to the information on the manufacturer's website: CFX Support 2 x PCIe 3.0 x16 SafeSlots (x16, x8/x4) [CPU] 1 x PCIe 2.0 x16 slot (x4) [CHIPSET] 3 x PCIe 2.0 x1 slots [CHIPSET]

How exactly is it with the WLAN? Do I have to add a wifi card or can I theoretically connect it with a LAN cable? Or is it already included in the motherboard? I don't know exactly yet :) Thanks for the answers in advance

So either you have an Ethernet cable or you buy an additional WIFI stick. Alternatively, there are also mainboards that support WIFI directly (filter settings: wireless transmission/WLAN).

With this board you can also do a BIOS update without CPU or RAM should it be necessary. --- BIOS FlashBack The (UEFI) BIOS can be updated by the user copying a BIOS file to a FAT32 formatted USB stick, inserting it into the USB BIOS FlashBack port and pressing a key. Updates can be performed even when no memory and CPU are installed.

Hall professionals I would like to buy this motherboard and use the AMD Ryzen 5 5600X processor. As far as understood that the motherboard must be flushed with a new BIOS version. But just to be on the safe side. The processor is already plugged on the motherboard BEFORE the BIOS fush or only after the BIOS update? Or is it enough if I install the graphics card WITHOUT the processor at the beginning and connect the monitor? Thanks for the help.

OK. I'm giving you the answer myself. This mainboard supports "BIOS Flashback". This means that an "older" CPU is not necessary just to get into the BIOS and update it. This means that the new CPU does not have to be installed, but only the latest BIOS version can be installed via USB stick and "BIOS Flashback" button. As soon as this is done: Plug in the CPU / RAM / graphics card and connect the monitor/keyboard. The mainboard now starts and should recognise the new processor and display the BIOS mask.

Hello all I have a problem with my PC and since I have already tried everything else, I would now like to change my mainboard. Now I would like to ask whether this motherboard fits my Ryzen 5 3600X. Asus says that it is compatible with the 3000 series....

In itself, this is neatly listed on the ASUS support page https://rog.asus.com/motherboards/rog-strix/rog-strix-b450-f-gaming-ii-model/helpdesk_cpu ;-)

Hello Digitec I have bought an M2 SSD for the board. Unfortunately I can't find the right screw to fix the module. Where can I get the screw?

The M.2 screws are usually in their own little bag in the box. A small hexagonal screw is used as a spacer, which is screwed directly into the MB, and a flat screw is inserted into it to secure the SSD. If the screws are really not included, you should contact Digitec support and Asus will have to supply them. From the Asus site https://rog.asus.com/motherboards/rog-strix/rog-strix-b450-f-gaming-ii-model/spec: Accessories: 1 x M.2 SSD screw package(s) 1 x M.2 Rubber Package(s)

If M2_2 socket is needed, then Pcie_1 slot only runs x8 instead of x16. Or? On the one hand, M2_2 is the slot with the heat sink for the SSD, on the other hand Asus recommends: graphics card on Pcie_1... But it's strange that a motherboard is designed in such a way that the recommended slots interfere negatively with the graphics card running only on x8... OR the SSD has to be relocated on M2_1 (without heat sink). What do you think?

x8 is sufficient. Performance loss is within the measurement tolerance range. Besides, a Ryzen CPU only has 24 PCIe lanes. 4 of them are for the chipset of the motherboard and 20 "for the rest". I have both m2 on the Ryzen 5800x. Slots occupied besides the graphics card I also have a x4 10GBit network card. => would be 24 lanes if the graphics card were running on x16. But as mentioned at the beginning, x8 is perfectly sufficient. With PCIE4, x4 would theoretically also be perfectly sufficient.

Hello I have put together a new Pc for myself (This MB, AMD Ryzen 7 5800X, an old GTX 970 for testing, a m2 ssd and a hdd (both tested separately to rule out a broken hard drive), 2 3200mHz rams (also tested and they work). When I tried to boot the pc (after BIOS flashback with the latest BIOS for the new processor) I have no beeps and only the green q-LED is on. Now I have no visual output from the BIOS. Both with and without GPU. What could be a reason that the BIOS does not boot correctly?

Maybe just reset the UEFI/BIOS. To do this, disconnect the power and connect the CLRTC pins at the bottom of the board for 5-10 seconds (manual 1-17). Then reconnect the power and try again. I had a similar problem with incorrect RAM timings and was able to restart the system.

Hi, three things off the top of my head: 1. despite everything, I would check again whether the RAM modules are seated correctly. I have already made the mistake myself and thought they were in the right place. Possibly try booting with only 1 stick. 2. Check whether the latest version of the BIOS is installed, as this is necessary for the 5000 AMD. 3. Check all power cables again, sometimes the problem can be solved easily. What kind of PSU is installed?
