It's an AMD problem as well. It's absolute nightmare trying to research for a computer today. What ports can you use in what circumstances. Which slots go the CPU directly and which go to a chipset.
Which lanes are disabled if you use nvme-slot 2. Which slot has which generation etc. A proper nightmare.
And while we are at it, dedicating pci-lanes to nvme-slots must be one of the most boneheaded decisions in modern computers. Just use a pci-card with up to four nvme-slots on it instead.
- FridgeSeal 5y agoMaybe it’s because I bought a “gaming” motherboard, but the manual was pretty (for my understanding at least) as to what configuration of m.2 drives and PCIe lanes would run at what version, what went to cpu and what went to chipset.
- deckard1 5y agoThe issue is cross comparison, not reading from the manual of a single board. In the past you could look at the physical motherboard layout and could compare it with another motherboard. Today, it's merely a suggestion. You take the physical layout with a huge grain of salt because it's nothing but lies. Which means going to the website of every single potential motherboard you wish to purchase, downloading their PDF, and digging through enough caveat fine print documentation to make your eyes bleed.
- nijave 5y agoA card with more than 1 NVMe slot requirements PCIe bifurcation which not everything supports
- tjoff 5y agoThat's only because it's a niche feature. If that was the official way to do it then it would be supported by everything.
