PCI-E Lanes in X99 with 5820K

[luisbvs]

Hello people...

 

 

I need some assistance and would like to shed some light into my doubts... Please note that I might be completely confused with this, which is why I am posting here.

I am planning a new build and ran into the Samsung XP941 PCIe SSD which needless to say is awesome, BUT it needs 4 PCI-E lanes. Which is when I started looking into the details behind these specs and found that the Z97 chipset with the i7-4790k will be limited to 16 and if I run a single 16x GPU it will take them all and even if I go with dual GTX 970 in SLI mode, I will take all 16 lanes for it 8x/8x (Am I correct on this?).

So, I am thinking about going with an X99 chipset and the i7-5820k which will give me 24 lanes (8 more), this will allow me to have my SLI using the 16 lanes and the Samsung XP941 using 4 more lanes and even have 4 more lanes to spare.

Can someone tell me if I am wrong with my logic here? What would happen if you use one of these SSDs with an Z97 chipset and then try SLI?

Thank you!

The 5820K has 28 lanes and both the 5930K and 5960X have 40 lanes.

28 PCIe Lanes (http://ark.intel.com/products/82932/Intel-Core-i7-5820K-Processor-15M-Cache-up-to-3_60-GHz)

You'd be fine.

There's 8 PCI-E 2.0 lanes sitting about on the Z97 chipset. Plus the 16 PCI-E 3.0 lanes that will be consumed by the GPU.

This means that there are the 16 lanes coming from the CPU and another 8 lanes (2.0) from the chipset? 24 total?

Yes. Although you might want to look into it further.

M.2 shares the PCIe lanes provided by the X99 PCH. Depending on which board your looking at, when a M.2 is used, then either a SATA Express or USB 3 controller ports will be disabled.
