Pcie Lane Question

[Cronins1]

So I saw the new intel pcie ssd's that just came out and wanted to get one as my old ssd is reaching peak capacity (Also dat bandwidth!).  I read that it uses 4 pcie lanes for its bandwidth.  I currently have 2 gtx 760 in my rig and that's using all of my 4770k's 16 lanes.  My question is, can I run sli in 8x/4x or not?  I've seen conflicting statements on the internet about this.  Thanks in advance for any help.

Quote from anandtech: " Utilizing the CPU's PCIe lanes presents some possible bottlenecks for the users of Z97 chipset because the normal Haswell CPUs feature only sixteen PCIe 3.0 lanes. In other words, if you wish to use the SSD 750 with a Z97 chipset you have to give up some GPU PCIe bandwidth because the SSD 750 will take four lanes out of the sixteen. With a single GPU setup that's hardly an issue, but with SLI/CrossFire setup there's a possibility of some bandwidth handicapping if the GPUs and SSD are utilizing the interface simultaneously. Also, with NVIDIA's PCIe x8 requirement, it limits itself to a single NVIDIA card implementation. Fortunately it's quite rare that an application would tax the GPUs and storage at the same time since games tend to load data to RAM for faster access and especially with the help of PCIe switches it's possible to grant all devices the lanes they require (although the maximum bandwidth isn't increased, but switches allow full x16 bandwidth to the GPUs when they need it).  " 

 

From the looks of it it will work but reduced performance. Probably need x99 for it to work properly with SLI.

So, nvidia SLI requires 8x PCIE connection to use SLI. You can't run SLI with 4x connections unlike CF, so sadly I think you might need x99

[DildorTheDecent]

Also you couldn't run it off the chipsets PCI-E lanes since they are only PCI-E 2.0

 

So to really utilize that SSD you should be on X79 or X99. Or just go single GPU. 

[Redsun20]

Sadly, no. You would have to upgrade to X79 or X99 as said above. Since SLI has those requirements for high bandwith and fast speed, it will not work.

Do you even really need all that SSD bandwidth though?
