X399 Question

So looking at the new Threadripper cpu and mobo's ASUS is going to run 4 pci-e 3.0 X16. My question is this, will we be able to run crossfire/SLI in a x16 x16 or even in a x16 x16 x16 config. Rather then a x16 x8 x4 or some combination thereof.

Yes, it will be able to run X16, X16, X16, X16 on cards that support it.

If I'm wrong, please point it out. I'm always learning & I won't bite.

SLI is no longer supported past 2-way. So x16 x16 would be the target for SLI. Not sure about crossfire. But threadripper CPU's all have 60 + 4 PCIe lanes; 60 for the PCIe slots, 4 for chipset (I/O) from my understanding.

Ah, forgot about the 60+4.

So X16 with 3 cards is possible, but X16 with 4 is not.

4 would be X16,X16,X16,X8.

although X8 is totally fine, and doesn't limit gaming performance at all.

Well, x16 + x16 + x16 + x8. It's only actually 60 lanes to the slots, with a x4 for SATA and on-board access.

 

You'd need to check the Motherboard manuals to see slot details.

Crossfire will work fine but it will run in 16x 8x 16x 8x

Just to clarify, the boards have 4 PCI-e X16 slots but they are wired X16 - X8 - X16 - X8, X8 is more than enough to run any GPU on the market though.

X4 is more than enough to run any gpu in the market tbh.

almost all the X399 boards I have seen is X16 X8 X16 X8 with 2 PCIe spacing. I think one of them was X16 X16 X16

Neither of those combinations are correct as there are only (2) x16 slots on the Asus ROG Zenith Extreme.  This is actually how all the boards I've seen for x399 are so far.

The max possible on the Asus ROG Zenith Extreme will be x16 + x8 + x16 + x8.   If you want to run x16 only, you'll only be able to do that in a 2-way SLI as there are only (2) x16 PCI-e slots on the board.
