If you have a setup in which you have 2 CPU's, and for example, each has 40 PCI lanes, could you use a motherboard with a total of 80 PCI lanes, or would you only have the 40 PCI lanes from the individual CPU.

So thanks for reading guys, if this post sucked, I'm not sure what you can do, but if you liked it, go 'head and hit that like button, or maybe add me as a friend.

Depends on how the motherboard is also set up. It is certainly possible to use lanes from both CPUs.

I think you would 40 for each cpu, with expansion cards interfacing with their respective cpu.
