Mixing up PCIe 3.0 x16 connections on a motherboard can cause issues.

My motherboard is an ASUS TUF Gaming Plus Z370 with two PCIe 3.0 expansion slots. The GPU slot is X16, the one below it is also X16 but labeled "max x4." It seems both use Gen 3.0. Would a SLI configuration work for dual 1070 Ti graphics? I've noticed little impact on performance when comparing GPUs, though I'm curious about real-world experiences.

This board requires a specific configuration to function properly. It needs the correct settings to support Sli, otherwise it won't operate as intended.

Always better to be cautious.

This board fully supports SLI functionality! It's compatible with Parallel Processing Technology 2-Way CrossFireX and 2-Way SLI.

Crossfire won't work with your 1070Ti, but SLI should still be possible.

Which board are you looking at? It appears that the OP is using an ASUS TUF Z370-PLUS GAMING: https://www.asus.com/ca-en/Motherboards/...fications/ If so, that does not support SLI.

The support page for Asus mentions only Crossfire compatibility. SLI is not supported.

It’s best to avoid taking that chance. Appreciate all the support you gave! By the way, why are GTX 10-series cards no longer readily available? Did production halt for these models?

They've ceased producing the GTX 1000 lineup...as the RTX 2000 series and GTX 16xx models arrive.
