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"? Cheesy

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...

To be honest the performance on your RX 480 isn't that great. I do 1470 h/s on 600 W (At the wall) with 5x 480. And my bioses are not even optimized for zec mining !

So what i'm concluding from this experiment is that 1080 ti are very efficient (620h/s for 180W, 3.4 h/W), but they are around 3x the price of modded RX 480 (300 h/s for 120W 2.5h/W) or a modded R9 Fury (~450 h/s for 200W, 2.25H/w ).
So we got 30% increase in efficiency for a price multiplied by 3, that doesn't seem like the sickest thing after thinking about it.
As far as I understand the problem with nvidia is that we don't have a lot of control over voltage and memory timings, so we can't really exploit the cards power to a 100%, also the miner's are maybe not yet fully optimized.
Meanwhile with AMD cards almost everything is tweakable enabling miners to optimize their card for the sole purpose of mining. Just look at the R9 fury that is built on 28nm and achieving almost the same efficiency as a card built on 14nm !

Given these i'm pretty sure vega will blow the 1080 ti out of the water on zec mining once we unleash our modding community. I'm sure they are already fully prepared.
