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.

Okey so I'm planning a new build and I'm kinda newish to this as it would be my first build, the problem I encountered is that I'm gonna be running an SLI of 970 on a Z97 board with a i5 4690K wich has only 16 pcie lanes. My question is, would it be possible to add an extra pcie card (ac wifi in this case) to my build mantaining the sli? I know nvidia requires at least x8, so with an sli all 16 pcie lanes of the processor would be filled. Tanks in advanced.


 


Sorry for my english can be pretty bad

I am pretty certain this is impossible, I could be wrong.

If I'm right just use a usb wifi stick

Things in build state: Lan room , Gaming PC

Things finished: Lol wut

Not gonna happen.

Since you would be using all the PCI lanes of the CPU.

8x + 8x for SLI.

Can't he get a higher end board that has a PCIe multiplexer? Also, I thought it was just default the SLI cards to 4x to make lane room for the AC card. Obviously 4x isn't ideal, but I was under the impression that was how this usually worked.

Get a motherboard with built in Wi-Fi.

My plan is to make an MicroATX build, and i can't find a mobo that's sli compatible and has built in wifi, therfore i need the expansion card

Something like this would do.

Doesn't work like that.

If the CPU can't provide the nessesary PCI lanes then it would be pointless.

The multiplex works ONLY if the PCI Lanes are provide. Or else it will work like a standard SLI ready board.

SLI isn't compatible with x8, at least all the info I found says that

Sorry for my link then, I didn't see till after I had posted.

buy 290x cards

not in a microatx build, I don't want a furnace, and I've also allways been fine on the green side

Thanks, I was never quite clear on multiplexing. I have a 4790K and my only gripe is 16 lanes. I wish it had  48 so I could do 16x SLI plus PCI SSDs and RAID controller.

If you had one card it would run at a PCI-E Gen 3.0 16x lane, SLI divides it to 8x if you go for 2 cards which is still very good. PCI-E Gen 3.0 8x = PCI-E Gen 2.0 16x

I suggest you start from the basics http://www.electronics-tutorials.ws/combination/comb_2.htmlAnd also if you want to learn more about technologies learn the logical inputs.

Most micro atx boards only have room for 2 graphics cards and even that is pushing it.

im using a Gigabyte GA-Z97MX-Gaming 5 ang put it on a bitfenix prodigy m, wich has 5 expansion slots at the rear, that would give me an extra pcie expansion slot, i had a hard time finding both parts but it should be fine

mmm.

It's a gigabyte board not an MSI one....

sorry my bad but still i misswrote that, but still my point is valid, thats the bord i'm gonna use gigabyte GA-Z97MX-Gaming 5 wich is the one you posted, and it hasn't got built in wifi, wich I wish it had

SLI is not compatible with smaller than 8x connection. 8x will work fine, since Z97 (16 lanes from CPU) motherboards can support SLI.
