Good day,

I'm using an MSI z97a gaming 6 motherboard and an MSI r9 290x. I wanted to know if I can put my graphics card on the lowest pci slot to have more breathing room for it as well as my CPU cooler which is a Noctua Nh-d15. Will it decrease performance if I do this? More importantly will this work? Appreciate any suggestion.

It'll work, it's still a 16x slot: http://us.msi.com/product/mb/Z97A-GAMING-6.html#hero-specification

  1. Edit OP, select your entire post, and press the eraser button. It hurts us, night theme users...
  2. You can put it in the 2nd slot without a tangible loss in performance (it'll run at 8x instead of 16x, but that isn't a problem). However, don't put it in the last one, it'll run at 4x, and THEN you'll lose power.

if nothing is populated in the top (1st) slot and you use the 2nd (middle) slot wouldn't it still run at x16?

In theory, yes. But that's not how it works. Mobos are made so that when one of the lower slots is used, the entire set is configured as if all slots above were populated. That's unfortunate, but that's just how it is....

 

 

4x 3.0 is still more than enough for a gpu.

Again, the theoretical bandwidth says so. But in practical use, it does start to lose performance. The loss is small, but it does start to show up.

Does that apply for x99?

Depends on the particular mobo. Some do allow a triple x16 config (violating PCIe lanes maximun), but in that case, it wouldn't be an issue.
