Can my motherboard support Tri-SLI? (Z77 Fatal1ty Professional)

post #1 of 9
Thread Starter 
Hi all,

In the specs it says it supports:
NVidia SLI / Quad-SLI

I'm not sure if Tri-SLI falls under SLI or not. It isn't exactly clear to me.

Does anyone know?


Thanks!

Yes, it's weird, it says Sli -OR- Quad SLI. not sure what are they stating.

here the specs

- 2 x PCI Express 3.0 x16 slots (PCIE2/PCIE4: single at x16 (PCIE2) / x8 (PCIE4) or dual at x8/x8 mode)
- 1 x PCI Express 2.0 x16 slot (PCIE5: x4 mode)
- 2 x PCI Express 2.0 x1 slots
- 2 x PCI slots
- Supports AMD Quad CrossFireX™, 3-Way CrossFireX™ and CrossFireX™
- Supports NVIDIA® Quad SLI™ and SLI™

It seems only support single X16 or dual X8

Exactly, X16 or duel X8...

So would it be x8 x4 x4?

I did post a thread on the ASRock forum as well though no reply.

I don't want to spend $$$ on a third card if my board doesn't support it. And I can't find anyone else that is running Tri-SLI with this board which worries me.

Thanks Suj

I would say probably not.
The mobo will come with the SLI bridge if it supports a certain format.
In other words....if it supports Tri-SLI the bridge will come with the mobo.

If you didn't get the bridge in the box with the mobo.....it won't support it.

So why the stated Quad Sli as an option, what Quad Sli means for Asrock, kind of false advirstment i think.

What that means is you have two PCIe X16 slots, and you can run TWO single GPU or TWO dual GPU cards in there. If you run a pair of GTX-690 in that board, it's technically considered Quad SLI because you have 4 GPUs running together, even though it's two slots.

So, the answer is NO - you can't run Tri-SLI. You can't use an x4 slot (or x4 mode in a wider slot) for SLI unless you have hacked drivers, and that's totally not "supported".

That's exactly right.

Short answer is no. Pretty sure Nvidia cards in SLI need a minimum of x8 in the PCIE slot to work properly. The way around this is some mobo's use a PLX chip. Although, this chip isn't needed on x79 mobos as it has more PCIE lanes.
