3 way sli help

[scott1939392]

Hi Im trying to do a 3 way sli, however the manual says there are 2 different sets of places to put the graphics card. For example for 40 lanes I put it in pcie 1 3 and 4 but for 28 lanes i put it in 1 4 5. I dont understand, which one should i use?

Write down full specs of your pc.

Give us your part list. You can only 3 way SLI if you have a certain CPU or a PLX bridge

im using 5930k i7 and msi x99a xpower ac. Awhat does the 40 lanes and 28 lanes mean? its in the manual you can go read it

Alright. When you run 1 GPU it runs at x16 speed. Now each speed takes up a lane. So on the 5820k, 28 lanes, the GPU would run x16 and x8 I believe. On a 5930k and above it would run x8 for all gpus in 4 way configuration. So follow the manual and use the PCIe slots listed in a 3 way config.

so do i follow the one that says 40 lane or 28 lane?

40 lanes as you have a 5930k which HAS 40 lanes.

ok thanks. just 1 more question, MSI provided me with 4 sli bridges but all of them have 2 outputs only. Can I connect the first card to the 2nd card and then connect the second card to the third card? or do I have to get an sli bridge with 3 inputs?
