SLI and expansion cards
12/25/18 05:33 AM


So, I have a z97 Gaming 7 motherboard. It has room for 3-way SLI (which I will probably never waste money on). But like all other SLI-type setups ever, using the feature drops the number of PCIe lanes. It's either 1x16, or 8x4x4. The ports in between are x1 PCIe slots.

So here's my question: If I decide to get a USB 3.1 expansion card, which requires a x4 slot, and drop it into the last full-sized PCIe slot with nothing else (other than my video card in the 1st one), will it a) WORK, and B) drop my video card down to x8? Will dropping my video card down to 8 lanes bottleneck the performance?

This stuff is confusing.


Just broke my personal record for number of consecutive days without dying!
