PCI Express card slot assignements
Hi all - I have serached high and low for advice on this but have only succeeded in confusing myself.
I build media servers for my own use in live events and have a question that has bugged me for years.
I have an Asus Sabertooth motherboard, and my graphics card is a Radeon 7970. I have two further graphics cards which are used to capture camera and computer. The latency on the camera capture is pretty bad to be honest even with all the best components. I was wondering if someone could steer me as to where my cards should be sited on the motherboard?
The 7970 sits in the main PCIEx16 slot.
The other cards I have are a Blackmagic Decklink SDI Card Type:PCI Express 1 lane, compatible with 1,4,8 and 16 PCIe slots
I also have a Datapath RGBE1s which is a PCI Express x4 card.
The motherboard spec is
2 x PCIe 3.0/2.0 x16 (Single at x16, dual at x8/x8)
1 x PCIe 2.0 x16 (max at x4 mode, black) *1
3 x PCIe x1
The PCIe 2.0 x16 slot shares bandwidth with PCIe 2.0 x1_3 slot and USB3 E1/2 ports at back. The PCIe 2.0 x16 slot default setting is in x1 mode.
Can anyone give me some advice on the best siting for the cards?
I would be very very grateful indeed as my brain is in knots trying to work this out
Many thanks
Neil
