Rampage VI Extreme Encore - PCIE slot x16

Hey.
About slot x16 on Rampage VI Extreme Encore,

PCIe 3.0/2.0 x16_1
PCIe 3.0/2.0 x4 (PCH)
PCIe 3.0/2.0 x16_2
PCIe 3.0/2.0 x16_3

I have RTX NVLink SLI Bridge (4-Slot Spacing)
so

Can I use the first slot and the third slot for Nvlink run at x16?
or must be first slot and second slot?

Your bridge wouldn't be compatible with using slots 16_1 and 16_3. You'd need a 5 slot bridge, which doesn't exist.

Thank you for your response.
How is that became 5 slots?
The motherboard has only 4 slots

On motherboard from slot 1 x16 to slot 2 x16, it's 3 slot space == between them slot 2 x4 that makes slot 2 x16 slot number 3 and slot 3 x16 become slot number 4.

Is that correct?

read the manual on page 1-2
it's quite easy to see the PCIe slot spacing

pos. slot
1 PCIEX16_1
2 empty
3 PCIEX4_1
4 PCIEX16_2
5 empty
6 PCIEX16_3

slot bride size between PCIEX16_1 and PCIEX16_2 = 3
slot bridge size between PCIEX16_1 and PCIEX16_3 = 5

but there is another problem see page 1-8:

PCIEX16_3 is also constrained see table. suggest you use PCIEX16_1 and PCIEX16_2 with a 3 slot space NVlink.

Thank you so much for your explained, I understand now.

Encore SLI for two X16 are top two slots.*

correct, which ends up being 3-slot spacing for NVlink or SLI-HB bridge.
