I use drivers 378.78
I hardly know anything in the world of nvidia
but I am getting 1850 h for zec and using 616 watts at the kill-a-watt meter. and I know that is my hot meter my other meter would read 580 or so.
This rig has amd drivers loaded I could see if I can add a rx 480 to it later in the week.
I would be curious to see If I can run eth with the rx 480 and zec with the nvidia's
I am using 1 riser for the 1080 zotac mini the two 1080 ti are in full slots.
hahaha, the company produces consumption measuring device and calls it "kill-a-watt"?

Golden!
On topic - that is a really nice hashrate. From 5x480s I get 1530 hash, while using 800W (it's the sweetspot),
Nvidia blows AMD out of the water with zec.
Anyways, I read a lot online about the mini cards, gamers and "casual" users hate them, they say they throttle more easily,
their fan runs on higher RPM etc etc... so I'm back to square 1, I'm thinking about getting the full size ones, price is the same...
