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
