Will an M.2 eat up pci lanes on this mobo??

[radeson]

Hello,

Ive been looking at upgrading to this mobo with the haswell 5960x.
I also want to run 4 way SLI with the gtx 980's i believe.
The board has a PLX chip which allows it extra pci lanes.

Now my question is: Will installing an M.2 ssd into the on-board slot slow down the 4 way SLI, or interupt it in any way??

Well according to ASrock, with their Ultra fast M.2 they state:
ASRock’s Ultra M.2 has way faster data rate than other ordinary M.2 interfaces. The secret is we use the processor’s leftover PCIe 3.0 lanes to feed it, so it runs as PCIe 3.0 x4 (32Gb/s) which is over three times faster than our competitors’ PCIe 2.0 x2 M.2 (10Gb/s) and five times faster than mSATA (6Gb/s).

I dont think many cards can even use fully the PCI-3 data rate so I guess it wouldnt be a big deal.

Post removed, as Shmee is quite right, and the post referred to a different chipset.

I am a bit confused here, I think the OP has mentioned an X99 board from Asus, to go with a Haswell-E chip, not a Z97 board.

It would be good to know though, how the different X99 boards handles the sharing of the lanes.

Another post, since I botched the first one.

If Asus is going by the Intel block diagram:

You may be OK here, as the 28/40 PCI Express lanes are coming off the CPU (so it would be dependent on the CPU),

40-Lane CPU-
7 x PCIe 3.0/2.0 x16 (single x16 or dual x16/x16 or triple x16/x16/x16 or quad x16/x16/x16/x16 or seven x16/x8/x8/x8/x8/x8/x8)
28-Lane CPU-
7 x PCIe 3.0/2.0 x16 (single x16 or dual x16/x16 or triple x16/x16/x16 or quad x16/x16/x16/x16 or seven x16/x8/x8/x8/x8/x8/x8)

and the M.2 is coming off the chipset:
