Advice on GPU location

post #1 of 4
Thread Starter 
I'm going to do a build with ASUS Sabertooth MB. It has 3 PCI-E 3.0 slots. I'm only going to use one at this time now can I use slot 2? If I go with slot 1 the card will block the MB led's. I have read in the past to always use slot 1 for single card use, but its been many years so have things changed?

AS you can see in this pic of the MB (leds outlined in red)




Thanks, If this should be in another forum let me know!

It will work fine I believe, though it will only run at 8x bandwidth because the slot is only wired for 8x (performance of 16x vs 8x is about a 0.5% difference at best).

IIRC with only one slot in use the second slot should run at 16x, 8x only if the first slot is occupied.

Thanks, This is from the MB specs I was thinking slot 2 only downgraded to X8 if you were running two cards.

2 x PCIe 3.0/2.0 x16 (x16 or dual x8)
1 x PCIe 3.0/2.0 x16 (max at x4 mode) *1
3 x PCIe 3.0/2.0 x1
