1 card on multi card rig drops off after a couple mins of mining

[Newfeebullet]

Running Linux, aorus 1080 ti cards and on one of my rigs after a couple of mins of mining ccminer starts to get choppy and one of my cards, has a massive drop in hashpower until it gets kicked off the system and it runs 1 card short.  Mother board is msi z270 sliplus power supply is 2 1000w evga units. I've tried changing the gens and 4g encoding is enabled.  Any help would be appreciated

Have you tried disconnecting all of the other cards and just mining on the one you suspect has issues? That would be my first troubleshooting step.

Try lowering the clock or change the riser.

Most likely a unstable dying card if it is doing it to different rigs.
