5820k lane limitations

[Kamilz15]

i am planning to add in a second 980ti for sli and an m.2 plexetor ssd. I have heard that 28 lanes is not enough. is this true? how will this affect me in any way and in any situation?

It's plenty.

 

Each 980 ti would receive 8x, and the m.2 would take 4x I believe.

 

You'd still have 8 leftover.

what would you recommendi use the 8 left over for?

You don't have to use it

Whoops I goofed up

 

Your first card would run at 16x, second card at 8x, and SSD at 4x.  (Pretty sure atleast)

8x is plenty for another graphics card if you want to add another 980 Ti. There won't be any bottleneck in gaming at least. Apparently some workstation tasks need like 58x PCIe. Mental.

It also might be dependent on the Motherboard implementation. You should look at how the lanes are divvied up @Kamilz15 in the Motherboard manual.

msi x99s sli plus

The clue is in the name. That'll definitely support SLI. Likely will support 3 way SLI too, as many X99 SLI boards do. That PCIe SSD may take up the space though UNLESS it is a Gen 2.0 x4. If it is Gen 3.0 x4, I think the CPU uses it rather than the PCH. If the PCH uses your SSD, then it won't use the PCIe lanes. Same with x1 network cards.

4 (x16/x8/x0/x4*, x8/x8/x8/x4*) SLI x3, CrossFireX x4 *Forces M.2 to PCIe 2.0 x2  this is what it says but i dont know what the hell this means

Those are for more than 3 gpus. The lanes are shared when a m.2 is installed, so it forces to x2. Run just 2 cards and m.2 should run at x4.

• "The motherboard M.2 slot #0 shares bandwidth with SATA 6.0 Gb/s ports. When the M.2 slot is populated, two SATA 6Gb/s ports are disabled".                     this is what it says on pcpartpicker when i add a second 980ti to my build. what does this mean?good or bad?
