ASUS Hyper M.2 x16 Gen 4 card
Question about ASUS Hyper M.2 x16 Gen 4 card
Looks like this card doesn't work properly in PCIe v.3 machines with old am3 socket CPUs (FX9000, Athlon and friends) - I have installed 3 such cards with 2 NVME sticks in each, and only one stick in each card is recognized, no matter what positions inside the card I use. All Windoze, Linux and Solaris kernels tried in 2 machines (Gigabyte and Asus mboards) Is it worth finally buying a more modern mboard with PCIe4 slots, or I'll end up again with 1 stick per card? Any success stories are welcome
In order for the BIOS and then also the operating system to recognise and address all possible 4 NVME M.2 SSDs installed on the adapter,
firstly, there must be a PCIe x16 slot on the mainboard that is effectively connected with 16 physical PCIe lanes.
Secondly, this slot must be able to be set in the BIOS to use 4x4x4x4 lanes.
The "magic word" here is bifurcation.
PCIe bifurcation allows a PCIe slot (e.g. a x16 slot) to be divided into smaller blocks (e.g. 4x4x4x4) with regard to the available lanes.
In this way, 4 SSDs can be addressed in a slot connected with 16 physical PCIe lanes,
where an NVME M.2 SSD occupies 4 physical lanes.
Whether a mainboard allows/supports bifurcation for one/more PCIe slot/s can be found in the specification of the mainboard.
