Long story short, I had a ROG Strix Z-690 E-Gaming WIfI motherboard that I had to RMA 3 times (It literally caught fire the first time, then the memory controller just died for the last two rma's, and killed both memory sticks in the process), complete nightmare... But that board saw all of my 4 NVME's and all 4 running at GEN 4. I finally snaped and got a ROG Maximus Z690 Hero. No more memory problem but I'm having issues running all 4 NVME's in GEN 4. All 4 drives are WD Black SN850's and are GEN 4 type drives.
If I read the manuel right, the top nvme slot is cpu bound, so this one is used for my OS. Every other nvme slots are chipset bound, so these drives are for my data and games.
So, the manual says that the M.2_2 Slot is PCI-e 3.0, the Strix Z690 are all PCI-e 4.0....Don't know why Asus downgraded that slot to 3.0 at almost double the price tag. If I want to run all my NVME's in PCI-e 4.0, I have to use the ROG Hyper M.2 card, this card can run 2 x GEN 4.0 in the PCIEX16(G4) slot as per documentation. Thing is, it only detects one of the drives, like if it was installed in the PCIEX16(G5)_2 slot.
You guys have any idea what's going on here? I truly love Asus but these couple of months have been a nightmare.
Any info would be appriciated.
