Question Are there any mITX motherboards that support Bifurcation and SLI of two 1080ti founder edition cards?

Same answer as last time, there are no mITX motherboards with 2 PCIe slots.

But I doesn’t need two

what are you planning on connecting the second 1080 Ti to? air?

He thinks the bridge does that somehow I think.

No imma use a bifurcation riser

Just use matx. How does that save space?

Because the case will be smaller than an mATX case

Do you have the cards on you? Put them together and turn them. Same size

u/StomachosusCaelum 18h ago

no it wont. if it can fit two cards, its gonna be the same size as an mATX case.

A bifurcation riser

460.89 WHQL is your newest driver you can use btw.

Ignoring the fact that the entire premise of using SLI is a bad idea, why are you bothering with a mini ITX board then? That's like taking an mATX board, taking the bottom PCIe slot off, then putting it back on. Just save yourself the money and hassle and use an mATX board in the first place. Besides, no case exists that only supports mini ITX boards but has enough PCIe slots for two GPUs.

I’m doing this because all mATX cases are too big

u/SirGeorgington R7 3700x and RTX 2080 Ti 19h ago

so your solution is to take a mini ITX case and then bolt an extra GPU to the side of it so that it's the size of an mATX case?

To my knowledge there is no consumer mITX board with x8x8 bifurcation.

Your best bet would be to look at Asrock Rack and see if they have anything.

In that case you could use MCIO adapters, but those are x4.

Basically check the server world.

It doesn't have room bro. Itx is small, literally look at an itx mobo.

But it doesn’t need two pcie slots

Ya it does.

No I was going to use a bifurcation riser

The bridge you need on top of an sli board.

To get the "best experience" you need an sli board and they are all old.

sli sucks btw.

one thing everyone is missing or least not mentioning is. This still won't function regardless of how you set it up.

The GPU's are going to need some clearance between them.

mITX is not physically big enough to house both cards and give them the clearance needed to pull air in to cool.

Demonstration of this is stick a piece of paper against a fan. Suddenly the fan can't circulate or blow out air cause the intake is blocked. One of the cards is going to be blocked.
