PCIE lanes

[cfrozer]

Does the i7-7700k have enought PCIE laned for 2x GPU and 1x M.2 NVMe SSD?

[xentropa]

Yes, though the nvme ssd might use the pch pcie lanes.

[Jurrunio]

probably no. 7700k only has 20 PCIe lanes, 4 of them to the chipset. SLI requires each card to get 8 lanes, so that leaves nothing for the NVMe SSD.

 

Why not get a SATA SSD? You can only feel the speed difference through benchmarks and read/write enormous files on them.

[sazrocks]

Yes. The ssd should go through the chipset.

Why do you want an NVMe drive?
As @Jurrunio said, there are very few situations it's noticeable over a good SATA SSD.

24? PCI-E?! DMI 3.0

[Jurrunio]

My bad, OP's plan will actually work. According to this:

The 24 PCIe lanes showed here should be a sum of CPU PCIe lanes and PCIe lane gained by reassigning HSIO lanes into PCIe lanes. Do note that these converted PCIe lanes are slower (lower bandwidth) than those from the CPU directly. Might result in speed reduction, but that's just my guess.

There is no difference between using 1xGPU(1x16xPCI-E)+M.2 NVME or 2xGPU(2x8xPCI-E)+M.2 NVME whatsoever...
