Guys i just do not understand, why people are saying, that 1080 TI ist good for mining. Correct me if I am wrong, but:

1080 TI costs about 800 EUR.
You get a used GTX 1070 from 360 to 400 EUR

1080 TI does 600 sols
we need also 1,5 x 1070 to have 600 sols, because 1 gtx 1070 produces about 400 sols

With this performance, the undeclocked 1080 ti consumes 160 Watt
for the same performance 1,5 1070 about 140 + 70 = 210 Watt

so the difference is 50 Watt an hour, that makes 1200 Watt a day, which is depending on the electricity costs (let's take 0,12 EUR for our example) about 14 cents a day,
which makes in month 5 EUR.

So the for the same performance the price difference is 800 - (400 +200) = 200 EUR
that is about 40 month... just to pay for the price difference... !?!?

Hi thespycry,
Here are some numbers to go through.

The price of 1080Ti founders edition is $699.99 & 1070 is $400

1080Ti out of the box does about 690h/s for the power draw of 250w
1070 out of the box does about 400h/s(I don't have one so used your number)

To get 690h/s you need 1.72 1070 GPUs

Now for power

1080 Ti = 250 * 24 = 6000w = 6kw
1070 = 140 * 24 = 3360w = 3.36kw
1070 Adj for 690h/s = 240.8 * 24 = 5779.2 = 5.77kw

ZEC Production

1080 Ti = 0.0571/day Approx(whattomine data)
1070 = 0.0348/day Approx(whattomine data)
1070 ADj = 0.0571/day Approx(whattomine data)

So in a day with ZEC @ $107/coin it is possible to make

1080 Ti = 6.1097- 0.84(power) = 5.2697
1070 = 3.7236 - 0.4032(power) = 3.3204
1070 Adj = 6.1097 - 0.6924(power) = 5.4173

To get 1080Ti's level of earning(20 cent more) you will be spending $688 instead of $699.99 for 1080Ti a difference of $11.99

Now this is based on the assumption that 1070 will do 400h/s for 140w if not then I don't think 1070 is that efficient.

Hope this helps, If I made any mistake please let me know.

Regards,
BLife

No the best GPU for ZCASH is the Radeon 7950/ 7970/ 280x which you can buy second hand for like $50-$75.

Each will get you 300 H/s. So impossible to lose money on those.

Keep in mind they use 200 Watts however.

not to disturb you guys , but at the moment , for equihash , BEST SINGLE CARD (1 pci express ) is not nvidia... but is ATI.... Radeon pro duo. cost around 700 EUR + vat ... brings in from 900 to 1100 sols at around 280 - 380 w according to how u configure)

since op does wrote he does not care about electricity...\

Of course greens are more efficient , but this is at the moment the fastest.

aka "whocares"

I almost exclusively use AMD Fury and AMD Pro Duo. The Pro Duo will do 1000 sols and I can get them to do 920 sols at about 300 watts. I have used very few Nvidia cards because of the limited coins that could be mined in the past and typically inferior speeds.

I did order the following items to test out. They arrive tomorrow so I am looking forward to modding them.

5 - Zotac Mini 1070
5 - Zotac 1070
5 - ZOTAC 1080 Ti AMP
2 - Titan Xp

Edited to add:
The Titan Xp's arrive Monday I think

One thing that is appealing about a 6 x 1080 Ti rig is that once your ROI is over you can bring in some really sweet profit every year after that. They will also be worth mining with for a good number of years since they're the current top end GPU. The resale value will be excellent also. It's a steep price to pay up front, but I think it's worth it in the long haul. Currently you can bring in over $11,000.00 a year after power costs with a single rig. That's an appealing prospect.

If you do have the money to spent on 1080 ti then It would be the most suited GPU for mining zcash not only on this one but most of Coins that is possible to mine with GPU but considering on the amount or price of that gpu isn't really cheap at all.For now I have Rx 470 but I do have still some doubts on mining zcash I don't know where to set-it up.

well i've seen that i cant run a 1600 psu @ my electric plugs. do you think i can 6x 1080 with a 1200 psu?

If you're willing to lose a modest amount of production and run them at lower power use and you'll easily fit 6, even 6 1080 Ti. As an example, for ZEC and 1080 Ti, when set to a power limit of 160W I get ~80% of the production as compared to when it's set to 300W.

how much watt of the psu would u guys leave for the system? is 150 watt enough to run everything expect the gpus?

if it is a dedicated mining rig 150 watt is okay more like 125.

Say a 50 watt cpu
a ssd or a hdd
a few fans
a stick of ram

I don't have these issues much as I don't use 6 card rigs

I prefer 4 card or 3 card setups. with overhead for the psu's

Maybe with good settings.

Most of nvidia zec miners said 1070 is the best $/hash , in some cases it's the 1060 , i think if eth will turn pos then most of miners will start building nvidia rigs to open more options

I just picked up 8 of the Zotac Mini's and will be using them in 2x 4 GPU rigs

Quote from: LarryL on May 04, 2017, 07:00:07 PM

im thinking about building a 6 gpu rig with 6x gtx 1080 ti, can anybody recommend me a psu wich is strong enough for that?

EVGA 1600 would do it and would be what I would recommend.

You'll need molex 4-pin or Sata risers though, won't have any PCIE left over to really run the risers unless you buy splitters but I wouldn't do that.

I have one Zotac mini 6gb-good card, but have tendency to heat up a little comparing with MSI 1080, which are rock solid at 500 without any tunung. Without any adjustment Zotac does 285mh on Linux. I am gearing up to do some power state improvement; no doubt they can do more.

Both cards work fine on H97 anniversary mobo with risers

The 1080ti is great and has a ridiculous hash rate, but it's also ridiculously expensive and from a ROI standpoint, it doesn't make much sense to me. For some, maybe. That's just my opinion.

yeah, im thinking about wait a few weeks and hope for a price drop as soon as the new amd card is released, what do you think?

I like the R9 fury if you can get it for a deal. There for awhile they were 239. You can undervolt the hell out of them and still get 400 h. They can do more if you don't want to undervolt them. I have one running right now. 6 Cards and it fluctuates between 2400-2500 and uses 800-840 watts. I think I can get lower, but I'm using MSI AB and it only allows you to do -96mv. I'm going to try to do it manually on claymore to see if I can get a little bit more out of it. 750'ish would make me pretty happy.

Unless the hash rate is ridiculous and the numbers work out (hasn't been the case so far) - I don't like to go too much over $200. The 1080ti is great and has a ridiculous hash rate, but it's also ridiculously expensive and from a ROI standpoint, it doesn't make much sense to me. For some, maybe. That's just my opinion.

well i plan to build a 6x (or 7x gpu if possible - but i think its not with nvidia?) mining rig with gtx 1080 ti cards. if you can recommend me a motherboard, psu and cpu for it, it would be awesome.

thanks in advance

These motherboards go out of stock pretty quickly, so grab one now if you're sure you want to build a rig.

If you want to do 6 GTX 1080 Ti with a single PSU you need this or something with the same specs and connectors.

https://www.newegg.com/Product/Product.aspx?Item=N82E16817438033&cm_re=evga_1600_watt-_-17-438-033-_-Product

Any socket 1150 Intel CPU will work for mining, even the cheapest Celeron. If you want to use the rig for office work, web browsing, streaming video/music while it mines then I suggest an i3 from that generation.
