RTX 3080 @ PCIe x4 3.0

[axxy750]

Hi there,

 

the upper PCIe slot on my Asrock Z370 Pro4 is dead so i have to use the lower one at x4 3.0

My 1080 ti works fine with the slower slot, but my Zotac 3080 leaves my display black. The LEDs and Fans are on, but my display won't show anything. 

I'm using a be quiet! 750W Straight Power Platinum PS so that shouldnt be the issue. Is my card broken or do you think its because of the wrong PCIe slot?

 

Thanks for any replies!

Have you tried using different display outputs?

Was the 3080 working before? Did you buy it used or new? If the 3080 was in the upper slot when it went dead it's possible whatever happened to break the slot also damaged the 3080. The 3080 should still work in the x4 slot, well enough to get display from it, I wouldn't try to game with it in there. I recommend testing the 3080 in different computer if possible.

I don't know, it just arrived today. It's new. The upper slot died due to an absolutely avoidable fuckup on my end - the 3080 was never in there.

I'm trying to find an 1151 Mainboard ASAP but before, I would be glad to know it the card's okay.

The PCIe lock got stuck and i wasn't able to reach it, so i pulled the 1080 ti from the left a bit and then I already heard the cracking sounds from the slot "pins". It's loose now. The slot itself was never the tightest anyway, maybe should have reclaimed it immediately when I received it.

sorry bro, thats real sad

Update: Black Screen is gone as long as i only use 1 display, not 2. As soon as i add the second DP cable the display starts flickering / goes black for several seconds. The main display works fine. GPU-Z says it's running @ x4 2.0, sometimes x4 1.1. New mainboard incoming.

 Then, you should like, replace the motherboard dude. You won't be getting the performance out of the GPU you paid for anyway using slot X4.
