Is my GPU in the right PCi slot?

Hello :hello:

I recently build myself a new system, containing a single 680GTX. But when I was looking at GPU-Z the other day it said this: PCi Express 2.0 x16 AT x8

The x8 makes me worry... I installed the card in the second or third Express slot (Motherboard : Gigabyte X79 UD3), I thought every slot could handle x16?
Is this something to worry about? (E.g. reduced bandwidth or something)

Thanks in advance


I have enough lanes, my cpu has 40x

The primary gpu slot is usually, but not always the slot closest to the cpu.
But from gigabytes site
1) 2 x PCI Express x16 slots, running at x16 (PCIEX16_1, PCIEX16_2)
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
2) 2 x PCI Express x16 slots, running at x8 (PCIEX8_1, PCIEX8_2)
* The PCIEX8_2 slot shares bandwidth with the PCIEX16_2 slot. When the PCIEX8_2 slot is populated, the PCIEX16_2 slot will operate at up to x8 mode.
(All PCI Express x16 slots conform to PCI Express 3.0 standard.)
Good luck.

Thanks! I looked through my motherboard book and found out what you said... So I moved my 680GTX from the 2nd PCi slot to the 3rd (x16). Thank you! :D

The reason I didn't use the 1st slot is because of airflow,...
