Asus Maximus XI Gene - DIMM.2 - PCI-E x8 ???
Yeah, seems like a very nice board for overclocking, but what the hell is up with its DIMM.2 M.2 "extension" slot?
If I understand it correctly, populating the DIMM.2 slot inevitably leads to setting the PCI-E slot to x8 instead of x16, since DIMM.2 is wired directly to the CPU's PCI-E lanes instead of Z390 chipset. Why would anyone like/do this? x8 is going to be a bottleneck for modern GPUs. I was seriously considering the Gene for my new CFL-R build, but not like this. Essentially, DIMM.2 slot is rendered unuseable due to this and I simply don't understand why Asus has implemented it this way? Yes, it's nice to support 4 M.2 drives in theory, especially on a mATX board, but like that, I feel it's very counterproductive and also not obvious to unsuspecting customers that it will limit PCI-E to x8, unless reading the specs very carefully... Kinda strange, I'm not sure what to think of it.
(btw, I think it's the same for the Extreme, not sure though.)
