Hello,
This period I am testing my first 6x1080 Ti mining rig. Everything was working fine (4300 sols) for 4-5 days until today. From the 6 GPUs it seems that only 3 work. All connections from 2 PSUs are fine, risers are OK, PSUs “test” (fan test) is OK etc. From the 6 GPUs none has lights on the brand (ASUS) as they used to have. Also only 3 of them have working fans and only 3 “blow” air (but not hot as they used to be). Lastly I can not connect my monitor using an HDMI cable as I used to do my monitor erros says “no video input”
I had in mind a PSU error but as i mentioned before, “test” (working fan) is OK.
My bad, what was your temps?
i`m having similar issues
6 x 1080 TI , all can work very well for a week, suddenly just stop working (temperature never higher then 68) and i need to reboot.
Found the problem, but not the solution. All 6 cards working properly when they are connected directly to the motherboard. Tested one by one. Unfortunately when i plug the riser again one by one GPU they do not work. So problem is to risers. 6 risers broke at the same time? Is it possible? what to do next?
I had a series of bad risers, could not get more then 4 GPUs to work same time.
once i replaced to a new v 006 with 6pin it all resolved and now running 8 GPUs
Unfortunately problem is PSU. I do not know why “test” was OK.
too many risers per cable
dont use the molex to sata extension cables…
honestly the risers should just not come with those extensions

The rule is to dont plug more than two risers per cable, right?
max 2, do whatever you can to do only 1 per cable if possilbe… 2 per cable is last resort

they are very dependable, everyone i have tried worked perfectly, and they have a blue led on them showing they are on. no previous versions have the led.

Yes, actually i meant at least ver 007. All my cards are on sata 007, and have no problem with them.
