According to our information, this should not be a problem. Also, this is not a fake product.

Well, an internet search (I can always recommend) ;) shows no result. So probably not

Since you are putting them in the slot, they will only fit DDR4 motherboards.

Well, I have the same thing and it works great for me.

Since I use the system on an older INTEL board (without any problems), I can't help you much. In any case, it is important that the latest UEFI (BIOS) is installed. You might find the problem there (in the BIOS).

0 GB - These modules do not contain DRAM memory and are intended for aesthetic purposes only.

According to my own research, this dummy can only be used for DDR4, sorry. :(

No, this is a real RAM bar, only with 0Mhz. Intended for when you install e.g. 2 8GB bars (Corsair Vengeance RGB PRO) to also occupy/illuminate the other 2 banks.

These are 2x 0 GB RAM bars. Let's say you have 4 RAM slots, but have only filled 2 so far. Now you think this looks stupid and you would like to fill the empty slots as well, but you don't need any additional RAM. Then these dummy bars are the right thing. These also have RGB, so they are indistinguishable from the "real" Corsair Vengenance bars. This product is therefore purely cosmetic / optical in nature and serves no technical purpose.
