Asus Hyper M.2 x16 Gen5 Card - will it work in a gen 5 x8 slot?

[Teletha]

Hi

 

I was wondering if i will be able to use all 4 drives on the card if the slot is limited to gen5 x8 speeds. I know not all drives will be able to get full speed at the same time but i wanted to know if the card shares the x8 speed between all drives or if its going to disable 2 drives and only use 2 drives in x4 each.

If its a x8 slot you can only use 2 drive if you have bifurcation support on the board.

 

What slot of the board would you be using it in? I'd search the manual for bifurcation and the slot it would be used in to see if 2 or 1 drive would work.

 

For most desktop use, I'd go gen4 drives, or go optane if you want the fastest storage.

Since it drops to a x4 when using a m.2 slot, why not get a single m.2 pcie adapter and put the other m.2 in the m.2 slot on the board?

i already have a special pcie gen3 card that gives me 4 slots but they are sharing gen3 x4 speeds that why i wanted to know if this card would be an upgrade if it can actually give me 4 slots

The card relies on bifurcation support from motherboard bios, to split the 16 pci-e lanes in the slot into 4 groups of 4 pci-e lanes.

If your motherboard only routes 8 pci-e lanes to the slot, then IF the motherboard supports bifurcation for that slot, then you would be able to have TWO m.2 drives onto the card.

 

On your motherboard, when a card is inserted in the second slot, the 16 pci-e lanes going to top slot are now split into 8 for the first slot and 8 for the second slot.
