Stupid question about pci-e

[dr_dark]

Can I combine with riser card two pci-e x8 ports into one pci-e x16? I understand that the question is stupid, but do not throw sneakers at me

Could you like type normally next time?

 

As for combining. No not possible.

If you mean if you can connect two cards to a single PCIEX16 slot, that is not possible without bifurcation support.

I think they are specifically asking to make their 2 x8 ports the speed of one x16 port here.

No.  i mean one pci-e x16 gpu to two pci-e x8 ports.  Experimenting with an old server motherboard.  It has two pcie x8

Dude just type normally instead of putting verified marks and making a scroll list. This is literally unreadable.

 

Ok so what server? What board even? We need more info here. It is technically possible but your hardware needs to support it.

No, but you can use one x8 slot for the x16 GPU.

I apologize for the font. Supermicro x7db3 motherboard, dual xeon e5450. It became interesting: if port bifurcation is possible, is it possible the other way around? But apparently this is impossible.

Ok so do you want to combine your 2x8 ports to a single x16 port or is it the opposite you want to do now?

 

Either way this board doesn't support bifurcation it seems and combining pcie ports isn't possible.

 

Besides this server is ancient and slow so getting a faster pcie bandwith isn't really going to do much if the cpu can't keep up.
