PCI bus question

Hello,

 

So I currently have filled every single pci slot on my motherboard.  I am wondering if this is bottlenecking the PCI bus?  I have a sound blaster z sound card, 2 gtx 660's in sli, my wifi nic card, and a ocz revodrive x2.  Is it possible to be maxing out the PCI bus?

Technically I think you mean PCI-E not PCI. PCI means Peripheral Component Interconnect while PCI-E means Peripheral Component Interconnect Express. Most modern motherboards have just one PCI slot if it has any at all the rest being PCI-E.

True, so any opinion on the question at hand?

I believe Ivy Bridge has 20 PCIe lanes in the PCIe controller. Your SSD is likely plugged into the x4 slot at the bottom of the board. With your cards and the SSD plugged in, it comes out to 20 PCIe lanes. PCIe x1 and PCI slots are controlled by the Southbridge. Therefore, there is no bottlenecking going on.

You may have filled your lanes, but I don't think the bandwidth will be bottlenecked. Your sound card and wifi card will not use much bandwidth at all. Your GPUs will be using most of the bandwidth, and while you are using them heavily, I doubt much will be going on with your Revodrive :D

Ivy Bridge has 16 PCIe 3.0 lanes from the CPU, and 8x secondary PCIe 2.0 lanes from the Z77 chipset.

 

Not sure what your motherboard config is but I'll assume the standard 3 x16 slots (which will be running at x8/x4/x4 if all populated) and 3-4 x1 slots which will all be run at x1 through the chipset.

 

Basically, you're probably fine.
