i5 4690K SLI with an extra pcie card?

Go to solution Solved by Brandonberg,

The Intel Z97 Chipset supports 16 PCIe 3.0 lanes via the CPU and 8 PCIe 2.0 lanes via the PCH (or Z97 chip).

 

 

If you run SLI you will require all 16 Gen 3 lanes from the CPU. These lanes are normally linked to the PCIE16_1 and PCIE16_2 and are normally color coded separate to the other lanes. (on my Asus Maximus VII Ranger they are the red slots)

 

The other slots can be used for upto 8 lanes of PCIe 2.0 which is controlled via the PCH and are normally color coded black. These are INDEPENDANT from the Gen 3 lanes for your SLI Graphics Cards.

 

So,

 

Your SLI setup uses both Gen 3.0 slots and both will run in 8x mode which will still provide enough bandwidth. (SLI required x8 minimum, hence 3 and 4 graphics card config not available for Nvidia on Z97)

 

You can plug your additional cards into any suitable black PCIe 2.0 lanes and everything will still work fine.

 

 

 

 

Here is a diagram of the Z97 chipset with relevent areas marked in red.

Edit:   This is the capability of the Z97 chipset however depending on your motherboard model, you may or may not have PCIe slots available. For example, most ATX Z97 boards will have 2 coloured PCIe Gen 3 slots and several black PCIe 2.0 slots. A mITX board however uses the same chipset but usually only a single PCIe 3.0 x16 slot to minimize board size meaning you obviously cant use the extra card.

I would suggest you get a 1x PCI extension cable plug it into the lowest PCI connector then wire it behind the motherboard tray and plug it into the Wi-Fi card and have it sit between the motherboard tray and the back panel of the case, or would be a cleaner look and you won't be able to find a z97 micro atx motherboard that would have space for a Wi-Fi card and 2 dual slot cards running in SLI.

What I would recommend.

And a PCI 1x extension cable.

Acctualy i have, Gigabyte GA-Z97MX-Gaming 5 with a bitfenix prodigy m, running an sli gives me the option to ad an extra pcie card

the Wi-Fi card won't fit trust me.

I've allredy have one in my sistem and its betwenn a sound card and a dual slot graphics card and it fits really well, its not even close to any of those

Then you are not running sli one card Is running at 4X.

Thats allredy been adressed, pcie lanes get filled with the sli, and the chipset gives 8 extra pcie 2.0 lanes that can handle stuff like a sound card or a wifi card maintaining the sli at 8x and 8x pcie 3.0 

Edit: Ok my bad just checked and saw that the last pcie16 slot is runing at x4, so your solution would be great, altho I'm thinking of insted of hidding the wifi card behind the mobo tray i could just put it in the last expansion slot on my case with a x1 pcie extender (by the way thanks for your help otherwise I woldn't have realised)

No I am referring to the actual layout of the slots on the board.

If you have a wifi card between the graphics cards you are using, and the bottom slot for a GPU it runs at 4x so no sli.
