GTX 1080 on a PCI

[Decimator216]

Hello all,

Going to be upgrading to a 1080 from a 980ti and I was worried about my motherboard PCI slot. Still running a PCIe x16 1.0. Curious if there might be some bottlenecking from such an old slot. (I know my MB combo is getting old in general and plan to upgrade within the next year or two.) My preliminary research suggests a minimal difference as far as the PCI slot goes but I wanted to hear what others think. Thank in advance!

Full Specs:
CPU: i7-2700k @ 4.0
Motherboard: Gigabyte Intel Z68 ATX DDR3 2133 LGA 1155 (GA-Z68X-UD3H-B3)
Ram: Corsair Vengeance 16 GB (4 x 4 GB) DDR3 1600 MHz
SSD: 120gb 840 and 500gb 850
Monitor: Asus ROG Swift PG279Q (1440p)

Hmm, not sure where you getting your info from.
That board with your CPU has a PCIe x16 2.0
If it's running at 1.0, then there's something wrong with it or you're using the wrong slot 😉

If all is well, the 1080 should work just fine on that board, though there is some, but not much, slowdown due to the older gen slot.

Quote from that page: "All PCI Express slots conform to PCI Express 2.0 standard."

You should be fine. PCIe 2.0 x16 gives like 99% performance of PCIe 3.0 x16 in most games.

Your motherboard has a PCI x16 2.0, not a 1.0. The software you used to check it may be faulty. And if you used GPU-Z remember to click the little question mark to run the mini stress test which will show your actual pci slot number. This is defaultly less through power saving features.

Also the PCI Express 3.0 cards are backward compatible, they will work fine on PCI Express 2.0/1.1 slots, with near to zero performance difference. So no need to worry about that.

It would appear that the amazon page, where I originally bought it, was not very descriptive. I see on NewEgg that it does in fact have the 2.0 after your post. Thanks!

I could tell you that as I have an Asus Z68 board, though mine supports Gen 3.0 as well.
