Bitcoin Forum

Hello, have you tried them all? in what proportion are those cards? price / hash rate / wattage ? What is your experience, mining various algos (eth, zec, lbc...)

Please note the top sticky thread, whose subject reads "No posts about GPUs or altcoin mining here, use the correct sub-forums".

Yeah, why are graphics card miners so blind?  ???

No offence, but this is just far too common thing.

sorry, my bad...
But when you read mining, and than you see hardware, first thing what is on my mind is GPU, ( i am mining for 3 years so far, i started with GPUs, and i am still using GPUs...)

I am kindly asking moderator to move this topic where its belong,

ok, tnx i see it now

In general, the 1080 isn't too popular. For the price and power use, there are better options. However, in some cases, the lower popularity does mean you'll be able to get them more easily, or at a less inflated price. (At my local Best Buy, the 1080s were the only ones consistently in stock on the shelves.)


1060s, 1070s, and 1080tis are pretty good. The important thing to consider here is rig density.

With some fixed number of slots, you can make better use of them with 1080ti cards rather than 1060s. However, the 1080ti usually does not offer the same individual price/performance ratio that you can get with 1060s. For example, I can get 3GB 1060s for around $200-$210 after hunting around. A 1080ti would cost me at least $700, and it does not mine at triple the rates of 3GB 1060s on any algorithm I'm interested in. (For example, I can get about 300 H/s mining Zcash with each 1060. I haven't seen many reported hashrates for a 1080ti that exceed 750-800, at best.)

With 1060s, you're getting a smaller overall rig hashrate for the motherboard/CPU/ram/etc. that you got to support the GPUs, so that's what can start to mess with the overall price/performance ratio when compared to 1080ti cards.


Another thing to consider is resale value. A 1080ti will most likely retain its usefulness for longer than 1060s, assuming you maintain them just as well.

I think 1080tis build will be worth it in the long run if u have enough money as once they have ROI'd there profit will be far greater then 1070 etc , But if u dont have enough money its best to go 1070s , also the less amout of 1080 tis as compared to other cards will make the managing easier make less sound ,heat etc

I would only bother with 1080's if I somehow managed to get them for a price closer to a 1070 otherwise it simply might take far too long to reach ROI.

1080 is no good

On equihash
1060 270/sec
1070 430/sec
1080 ti  635/sec

On amazon current prices
1060 $300
1070. $500
1080 ti $750

Rate / price
1060 .90
1070 .86
1080ti  .85

Assuming the above are correct the 1080ti is the best bang for the buck.

You also have to consider what scale you are going to mine on. Motherboards, power supplies, risers, etc are not cheap. One rig with six 1080ti would certainly be more cost effective than building two rigs with six 1060.

Yes, I also agree that you should forget about 1080, it is not only the price and power usage, and the hashrate is not too good compared to 1070, so it is not worth in ROI.

I have all three other models, they are all good but in different price range, 1050ti also good in ROI but too slow.

Is there any difference, between OEM brands??
Because some time, price difference is more then 100$...worth to pay?!

Other available markets,beside Amazon?? nwegg is "out of stock":((

Thanks in advance...

I have not noticed significant differences between brands but haven't tried them all. Different brands/models have different fan setups and more/bigger fans are better.

My son has two 1070s in his gaming computer. One is the premium evga and the other is the generic pny. They both oc to the same level and have the same hash rate. One doesn't have the fancy lights and stickers and didn't come with a poster.

It is very popular myth. Thanks to it 1080 are more cost effective than 1070/1060.

1080 535/sec
Amazon cost  $550
Rate/cost .97

How do you figure?

if you look at it from another angle. if hardware and space is a concern the choice is clear to me.
Performance, and price, and wattage, are very close to the same for these
(10-1080ti's)   =   (16-1070's)   =   (26- 1060 6gb)

The $200 1060 3gb perform on par with the 6gb but in the above example would save $2600

3gb cards have a problem or will very soon with the Etherium DAG file size don't they?

My numbers were for the 6 GB version.

The 6GB 1060 gets only marginally better performance over the 3GB versions when mining on equihash, which you mentioned earlier. For mining Zcash, the 3GB versions are far more cost-effective, at $200-$225 with some deal hunting.

The 6GB versions are a better choice for ETH, but ETH mining performance is not what you used in your earlier post.

You are correct. I wash referencing equihash performance. I still personally wouldn't buy a 3GB card and limit my options. Saving $75-$100 on a card that might not be able to mine everything isn't something I would recommend.

I was listing equihash because currently Zcash is more profitable to mine than ETH but that sometimes flops around the other way and I don't want to limit my options.

If you don't care about ever mining ETH yeah a 3GB 1060 is the probably the most bang for the buck card.

1070 FTW! Best price / performance ratio! A little OC and good cooling ang here you go!

1080 is generally 20-30% faster than 1070. If it cost <20% more than it is more effective.
There are 3 algo in which 1080 performs bad, even worse than 1070. But there are a lot of other algos.
E.g. neoscrypt:
1060 - 900+
1070 -1100+
1080 -1100
1060 is clear winner here .... if you won't look at amd side  ;D

I would agree with this...bad reputation of 1080 makes them to cost less, but they are very good for core algos, they fail only on eth,
So if price is close to 1070 I would go to 1080 instead.

Not only eth. 3 algos where 1080 are bad:
1) ethash 30% slower than 1070 very bad performance, but is cured by dual mining, giving slightly more than 1070 (~10%).
2) cryptonight. very bad performance
3) neoscrypt  ~1070.

1080 shine in (giving 80-100% of 1060)
1) skunk
2) lyra2r2
3) tribus

Best ROI should be with GTX 1070

I have only those NVIDIA cards, several 1080ti i took for test whitch are amazing cards but my opinion due to ROI(what most miners consider as primary question) to buy 1070.

I have much of them, EVGA, MSI, Gigabyte, Zotac, Paloc, ASUS(different types of them too) and rates for most popular hashes are :

eth : 31 - 32 mh/s
zec : 630 - 690 sols

You are right on card performances, but for the rig building cost, you should make it like: 1 rig of 6 cards 1080Ti need only 2 PSU 850W + 1 CPU +1 MB + 1 RAM..... while 3 rig of 6 cards 1060 need 3 PSU 850W + 3 CPU, 3 MB + 3 RAM... The peripherals' price is not cheap :D

For me, 1080 Ti is a good deal but I'm just started with a small budget, so I'm going with 1070.

Where are you getting 270/sec for the 1060? Mine does 300-310 at "stock" (they oc automatically) and 335-345 oced

1060 and 1070 for me. (my 1060s are more stable and less finicky than the 1070s and can be set to high memory an core clocks across every algo ive used them with).

I usually only invest whatever revenue the rig generates and buy equipment from that (very low starting capital).

While I do appreciate 1080ti I know that it will take too long for me to get increased hashing power.
Therefore Ive chosen the two low end cards (slow but steady with zero chance of loss). Also electricity for me is free so what I make through mining is pure profit.

I'd say you're definitely skimping on the PSUs there, especially for 24/7 operation, and even after messing with clock & power settings.

I can confirm 6 1080 Ti with 2 850W PSUs have no problem.

i would use only 1080 , or 1080 ti

I have 2 1070's but am waiting to upgrade to 1080ti's

I love 1070 gigabyte g1 gaming , why have 1 only 8pin pciexpress , and is a great in overclock with less consumption .

1060@6Gb with the best miner have currently 750 in neoscrypt, 1070 -1200 and 1080ti 1500. I have 1060@6gb, 1070 is too much better in the relation cost/benefit

Those 3GB cards still have a estimated 1 year lifetime to mine ETH

 The 1080 is mostly not popular due to it's high price - but for many algorithms it is very competative on hash/$ (just not on ETH which is what the majority of miners are interested in).

 It's a particularly good choice on ZEC and ZEN and the other spinoffs of ZEC, where it is a tossup on hash/watt AND hash/$ with ANY other GPU model (including the 1070 and 1080ti).


 This will change if AMD card pricing on the RX series drops much more, especially if those cards ever get back down to "close to MSRP" pricing.


 3x1080ti on a single 850 (even a GOOD one like the EVGA G2 850 or the Seasonic X850) will work reliably if you turn the TDP down far enough, but it hurts hashrate noticeably to do so which is a definite MINUS if you have a low electric cost.

 You are also leaving yourself a lot fewer options on possible future coins that might be efficient at higher power settings.


 The Gigabyte 1070 Gaming G1 has a TDP of 180 watts - that's 75 from the PCI-E bus, 105 from a PCI-E 8-pin connector that even the PCI-E SPEC allows up to 150 watts of draw from.
 You'd need to push it up past 225 watts to need a second power connector, per the PCI-E specs.

 The MSI 1070 card that has 2 power connectors is RATED for a 240 watt TDP (I've got one of those) - but I've never had it get much over 200 even PUSHING it, and the cooling won't handle MUCH more than 200 on that card without GPU overheating issues unless you have a VERY cool ambient temp and a LOT of airflow around the card.

sorry, what is the ETH hashrate for 1080ti?

Of all these cards, I choose 1050ti
Cheaper than all, you can collect a lot of farms, and if you take a good card, you can get 15-16 mh/s

I use 1070. Good power and quite economical. Good investment.

 Ballpark 35 Mhash/sec depending on where you can get the clocks to be stable at.

 ETH is a VERY bad choice for both the 1080 and the 1080ti, as GDDR 5x latency apparently has a bad impact on ETH hashrate compared to the GDDR 5 that the 1070 and below use.

 If the rumored 1070ti shows up with GDDR5, it might be the fastest ETH miner on the Green side - but will STILL not be competative with the Red side now that RX 470/480/570/580 prices have dropped back down to semi-close to sorta reasonable and availability is improving.
 I'm going to be VERY interested to see what it does on ZEC and the like where NVidia is strong - and what the final price turns out to be.

For example  , I got  gtx 1060  6GB  Samsung memory , powerlimit  73   memory overclocked to  4780MHz  GPU downclocked to  1400MHz   ETH mining  24,9 MH/s     , GPU 1870MHz  Mem, stock  ZEC mining   310 Sol/s
the same card with  hynix memory   after oc  21 MH/s  ETH   285 Sol/s  ZEC.

for a 6x 1080ti build, assuming undervolted, what is total system wattage?

I was watching a video, I believe BBT and he had a 6x 1060 GB setup only drawing 500 watts for the entire rig. I am currently modeling my build after that one, but so far I only have 2 cards out of the 6 it will eventually have. I think it is a pretty close estimate as I am just pushing 200 watts right now with 2 cards and the rest of the system. Figuring 50 W for the system at idle, that is only about 75 watts per card, so 75 W x 6 + 50 is 500 watts right on.

To get this the power limit setting in afterburner needs to be set to 60% and I also under-clock my core by -100 since it has little effect on mining performance (especially with Ethereum). I have tried +100 and +150 as well, but I need to adjust the power limit to run the core higher and the core clocks really seems to not effect the hash rate at all. The memory clock does though and I usually run that at +600 to +700.

I am going with a 6x1070 Zotac Mini rig which is consuming all together around 750 W after pretty much fiddling with the undervolting to find the sweet spot. AMD is much better for ETH, but ETH will be dead for mining next year

Now these cards are often in mining and they become cheap, especially nvidia 1050ti. Of course latest modelbis always better but it has very high price. For example you can get new nvidia 1050ti for 150$ but for 1080ti you need nearly 750$, difference is 600$ and with that 600$ you can buy 4 additional 1050ti. Of course 1080ti will pass more time and will be more useful but I wouldn't buy it now.

I would like to get the 1080ti but I would then need to also upgrade my PSU which is a cost I probably cannot afford so I think im going to go for the 1070 because I can purchase it sooner and just plug it in and go. I am going to check out the AMD side like someone suggested first though.

about 1000 -1100  watts at 60% tdp

  depends on the tdp  some cards are 275 tdp not 250

I have a 1080ti rig and from my experience so far my 1070 rigs are better value for the money.

With the 1070 finally getting back under $400 (Newegg pricing, saw 2 of them today at $399) it's taking back it's place as arguably the best NVidia mining choice for most algos NVidia is good at.

 1080ti pricing seems to have been going UP a bit lately - I can't remember the last under $700 listing on Newegg for one, been a month or so I think.

 1080 ti is still better from a "rig density" point of view, though, and any of the 1070/1080/1080ti options are close on both hash/$ and hash/watt when you figure them at the TOTAL SYSTEM COST AND POWER CONSUMPTION level.


 Gonna be interesting to see where the "1070 ti" specs end up at, and pricing on it, and where it falls in the efficiency and hash/$ spectrum - presuming it DOES actually happen.

Hello friends. Can someone answer me? How many hashrates and soles gives 1070TI ?
Sorry if this was already, I have not found.

I vote 1080s.

They are becoming reasonably priced if you can find a deal.
And there's plenty of coins using Equihash / Neoscrypt you can find to turn a profit.

for me, 1080TI, I know.... it's an expensive card but I prefer to manage the minimum number of rigs possible, my time it's a value too .... . What u think about that?.

1080ti cards are really good in terms of performance. With them, you can work longer and earn a crypto currency, but in the ratio of prices and hash rate they lose

with undervolting to make electricity reasonable
1050 - idk
1060 - eth 22-24, zcash 280ish, 90 watts
1070 - eth 30, zcash 450, 110 watts
1070ti-eth 30, zcash 500, 110 watts
1080 - people mine with these?
1080ti-eth idk, zcash 750, 180-200 watts

I've GTX 1080. I mine zec/zencash and have approximately 530-550 Sol/s. 165W 85%tdp. It could be better compared for gtx 1070. Hovewer on other algorithms I see better improvements.
It is not GPU with best efficiency/power usage indicator, but does its job well.

Thank you very much for the information. You helped me a lot. I think my choice will be 1070. The fastest return the investments

I have the 1050 TI / 1060 3 & 6 gb / 1070 / 1080 / 1080 ti

Each have their own set backs and advantages, I would recommend 1070 +.

The power draw of the High end 10xx series is pretty impressive hash/watt.

1060 6gb are pretty ideal for initial price / hash , given you get them at a good price, and it has decent memory.

Also, getting the 1070 - 1080 tis VS 1050ti/1060 saves A LOT on space / heat.

About 1080Ti:

I have a rig with 6 of them.
I'm mining Zcash with EWBF's Cuda Miner on Flypool. (Have %2 developer fee but you have an option to disable it.)

They are using 1300 W and have a speed of 4300 H/s, also they are making around 700$/m.  

https://i.imgur.com/hJpqEz3.jpg
https://i.imgur.com/aOLrxVJ.jpg

And here's my mining rig  :) : https://i.imgur.com/wSJlx7e.jpg

My experience is the following:

For ETH, the GTX 1060 3GB seems to be the best. I get 24MH/S for 75-80W (for around 200$) while with a 1070 I get 32MH/S for 90W (for around 400$).
Now if you want to mine ZEC for example, the result will be different, a 1080TI would probably be a better option.

You seems foolish buddy. GTX 1070 8GB card can be produce the 32 MH so you will be able to more income that card alone but if can get the electricity more cheaper in the sense we can make more money with that bro.
Performance wise alone 1080 8GB card is better than 1070. You can check in any site you will find the information states 1070i is the best card to mine.

OK, now I have installed / changed my gtx 1070 to gtx 1070ti just paid like 50$ for the change
and I can say that really 1070ti good choice if you can buy it around $450-470 - si it will be like 5%-7% more expensive over gtx1070 - but it massive 15-18% faster then gtx1070.
so you have 10% boost for free, for it is a good value! can recommend

I'm not foolish, it's pure math. You'll have a faster ROI with GTX 1060, on the long run you'll earn more with the GTX 1070. Today 1 GTX 1060 can generate 1.65$/day on ETH while a GTX 1070 will deliver 2.2$ (in the current conditions). At that rate you need 121 days to break even on GTX 1060 while it would take 181 for the GTX 1070 (that's almost 50% more!) and this is without taking power consumption into account because the gap will grow bigger. The GTX 1060 has a better MH/s per W.

When mining you need the fastest ROI because nobody knows until when mining will be profitable. The time to be break even will increase with difficulty increasing so it's not getting any better.

 It depends on WHAT you are mining.

 1070 ti is the most efficient card at ZEC mining right now with the 1080 a close second (but worse on hash/$ at any setting and the 1070 and 1080 ti are both fairly close on best efficiency OR hash/$).

 For ETH the 1070 matches the 1070 ti hashrate exactly (same memory system on a VERY memory-hard algorithm) and the 1070 blows the 1080 completely out of the water - the 1080 ti beats the 1070 but not by a lot, making the 1070 by far the hash/$ leader of those 4 cards on ETH.
 SOME 1070 cards will mine ETH at 32 Mhash/s but many of them do good to get to 30 - but even at stock clocks they pretty much all do more than 28.
 But for $400 OR MORE they are not cost effective vs a 1060 3GB card that does 22+ for about half the cost, and they are not even CLOSE to cost effective vs RX 470/480/570/580 cards in the UNDER $250 range that can generally get to 28-30 Mhash (with BIOS mods) and are very close on efficiency.

 Then there is Monero, where the Vega 56 is the current king of hash/watt (though some of the NVidia cards can argue there) and *WHEN* you can get one at semi-close to MSRP the hash/$ winner by a LOT.
 Vega 56 is even beating those old "open-compute" refurb Intel servers on hash/$....

 If you can find a Vega 56 for under $500, it currently has an ROI in the 85 day ballpark, and has been consistantly under 105 days for the last couple weeks.

I fully agree with you. In theory those RX cards should be better than the GTX 1060 but they are either outpriced or not available, GTX 1060 has become the best alternative for ETH. For ZEC or XMR, that's a different story. I tried my GTX 1060 rig on those currency and even if it's not bad, those cards are not high performing cards for those currencies. Somehow my whole rig was consuming way less power with ZEC and XMR than ETH. For some reason, the algorythm behind doesn't get all the juice from the GTX 1060.

EVGA GTX 1060 (got a couple of those) just went under 200$ now at Amazon: GTX 1060 on Amazon (https://www.amazon.com/gp/product/B01KUADE3O/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=laurentwillen-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B01KUADE3O&linkId=4a0844dd89527528d360205520f4501b)

Where are you at that RX 570 and 580 cards are "not available?
Outpriced a bit - still, yes, but that's dropped a LOT the last month.

 At current pricing I'm seeing on Newegg for them, you'd have to find 1060 cards a fair bit UNDER $200 to have a prayer of being competative on hash/$ right now.

Totally agree with you, klintistwood!

I've just purchased some P106-100 mining cards to test and really satisfy with the performances and I'm going to build a new mini farm with this card.
Each MSI P106-100 mining card costs around 251$ and average hashrate is about 25.1Mh/s. My 8 cards rig consume ~760W.
As I estimate, basically each P106-100 could earn ~1.9-2$ per day on mining ETH.

The test with 8GPUs, test's duration: 86hrs: Power Limit: 65%, Core: +46, Mem: +740, average hashrate: 25.05Mh/s.

 Must have been a Black Friday / Cyber Monday sale, they're showing as "$211.80" and higher now.
 On the other hand, Newegg had a few RX 570 cards at $209 for Black Friday - lowest is back up to $239 as of yesterday.

It's a hunt for the best price but it's critical for ROI. I'm collecting prices for EU here GTX 1060 (http://www.carte-graphique.eu/catalogue-carte-graphique/prix-nvidia-geforce-gtx-1060-performance/) but I haven't done it for outside EU. There is not a GTX 1060 below 200€, it's the first time I see this in EU since I have started mining a couple of months ago.

I would recommend the 1080ti over anything else due to reduced cost you need for mobo risers and general space saving.
I am trying to learn more about vega mining though

What kind of brand do you buy to mine ?

price / hash rate / wattage ==>> you should choose 1060/6gb

 Viable if you run them at about 230 watts or less (180 ballpark for the power supply that is ALSO running the MB/RAM/HD stuff) - and your power limit setting is RELIABLE (which is not always the case on Windows, Afterburner among other options will sometimes LOSE settings on one or more cards after a driver reset).
 I wouldn't push them much if any harder than 700 watts at the wall even on a GOOD power supply, for long term reliability reasons - even with the TDP turned down, you still get SPIKES on power draw quite a bit above the set point.

 On an overall "system cost" basis if you are aiming for max efficiency, the 1070 ti beats the 1080 ti on a hash/$ basis AND on a hash/watt basis - but the 1080 ti system will have a bit more ability to expand hashrate *IF YOU HAVE ENOUGH POWER SUPPLY CAPACITY* and are willing to live with lower efficiency - and the figures come out pretty close, you're not going to see a 1070 ti based rig making money and a 1080 ti rig losing money unless you're pushing the 1080 ti cards a LOT harder.

 At this point, on both the 1070 ti and the 1080 ti my "go to" card is the EVGA SC version.
 I like my Gigabyte Aorus 1080 ti cards, but the dual-8 pin power connector makes them a headache to get multiple cards hooked up compared to the 8+6 on the EVGA SC, and since I'm aiming for good efficiency the cooling on both cards is plenty and they perform equally 'till you push them up past about 220 watts (the better cooling on the Aorus lets it boost higher at that point for a bit higher hashrate and efficiency).
 The SC also tends to cost less than the Aorus, but on a $750 ballpark card the $10-$20 usual difference isn't a big deal in and of itself.

 5 x 1070 ti also fits into the power budget of my rigs, where I end up having to run only 3 x 1080 ti and set them to a somewhat less than best efficiency point (and STILL end up with less total hashrate).
 Down side is the 5 card rig WILL take up a fair bit more space - but even there it's not an issue in my specific case as my current "shelf/rack" design fits a 5 card rig very nicely on a single shelf with good cooling, but would be overkill for 3 and WON'T fit a pair of 3-card rigs on one shelf without major cooling issues.

Agreed, but at $572USD for the 1070ti and $798USD for the 1080ti, I am forced to consider all other options. :(

In my country;

GTX 1060 3GB = $194 USD
GTX 1060 6GB = $281 USD
GTX 1070 = $417
GTX 1070ti = $505
GTX 1080 = $535
GTX 1080ti = $764
Vega 56 = $535
Vega 64 = $558

Not really liking any of those options for a new rig. Sadly the 3GB 1060 seems most attractive.

Sadly? :) Why? 194$ is really good :)

Because I am almost at maximum density in my home and I have space for one more rig. Heat is already a problem here in summer ;(

10*1060 as a final rig is a bit meh when it is next to 8*1080ti 4*Vega56 and 4*Vega64

Then the best P/P is go for rx  RX 470/480/570/580? Hope to build may first rig ASAP, trying to understund best P/P.

Thanks for that breakdown QuintLeo - I'm currently running all 5 and 6 card 1080 TI rigs, just bought the parts to make a 1070 TI rig today to decide if I expand with the 70's or the 80's - Power and space no longer a problem, but I do try to run max efficiency and these 70's have me wondering if it will be worth it in the LONG RUN to go with which one.


Thanks again, hope to hear more.

1080 not TI is almost the same price as 1070ti in local stores. What do u think should I prefer for one small rig at home with 4 cards. What power block capacity would be enough for this?
thanks for answers. ;)

Hi Guys! I would like to ask for your help.

I would like to start mining, but I can't decide which card I should buy, tried to calculate it by Whattomine, but because of the spikes of different coins I had crazy numbers I think.

In my country these are the costs of the GPU-s.

AMD 570 - 300$
1060 6GB - 350$
1070 - 530$
1080 - 580$

And the base:
Asrock H81 PRO BTC
Thermaltake 1200W Toughpower
Intel Core i3-4170
4 GB DDR3 RAM
Costs: 490$

And my whole budge for it is 1870$

Thanks!  ::)

I have to warn you that there is a problem with 1070ti with neoscrypt algo, the performance is really low - same as 1070 card, no boost
but if you will not mine coins on that algo - tale 1070ti, properly overclocked it will be only 5-10% slower gtx1080

Looks like better to take 1080 their the same price at our stores. Thanks for answer.

I don't understand the hate for GTX1080.  I was planning on building some rigs with 1060's but it takes a lot of 1060's. The normal 1080 appears to be about twice as fast as the 1060 and while it is a bit more than twice the cost, you can use half of them.  12 gpu instead of 24 is a lot less hassle and a lot less complaining from the "boss".

Could someone tell me if the 1060/1070 mini's hashrate the same as the full size and do they run hotter because of the one fan or a lot hotter just looking to expand my Nvidia rigs thanks

Well, actually it's not a question of hate, but a question of maths.
How much electricity consumes your 1060's, 1070's, 1080's and your 1080Ti's, how much do they cost and
how many H/s or Sol/s do they generate? I also be apologist of the idea that overclocking a(ll) GPU(s) might
not be a good idea:

1 - Consider the higher temperature
2 - Consider the life cycle of the GPU under 24/7 high-temperature conditions


Finally:

I made an experience with someone that want to run a Mining Rig with 3 NVIDIA Gpus, 1060 EXOC, 120 W TDP
using a 1000W Corsair PSU, a ASROCK H81 BTC Pro, 8 GB RAM.
As he turned the Rig on, the electrical circuit went down, no functionality.
We repeated the experience at the kitchen, but were not successful:
The electrical circuit went down again, no functionality
Meanwhile he ordered a new 750 W PSU.

Are there some considerations that me and my friend are missing?

 Heavy memory limited algorithm most likely, same as ETH where the 1070 ti ALSO has pretty much identical hashrate to the 1070.


 I don't hate the 1080 - I just have yet to see an algorithm where they are the most optimal choice.
 They're usually CLOSE to 1070 / 1070 ti / 1080ti on a hash/$ basis though - and details vary with the card and the SETTING you run the card at, sometimes they're VERY VERY close sometimes it's an easily noticeable difference.

My Zotac 1070 minis IME pushes the same hashrate as normal 1070 cards to a point, but tends to be a hair slower when pushed close to the max TDP of the Zotac since they run hotter and can't boost QUITE as high.
My Zotac 1070 ti mini MATCHES my EVGA SC 1070 ti cards when used at "max efficient" settings, I've not tried it at any other operating point.
My Gigabyte 1070 ITX cards (before most of them DIED) pushed very close on hashrate with anything else at the same settings but a HAIR slower.
My MSI Aero ITX_sized card was a hair slower than anything else at same settings, and had WORSE cooling than any other 1070 I have used (including an ASUS Turbo blower model).

Can't speak to 1060 cards as I don't own any.

I also think 1080s can be the best option under not-so-special circumstances (price, performance, profit, power cost, power consumption, space saving...). Also if you check whattomine.com calculator page, it will tell you the profit is quite reasonable with this card. To match 3x1080 you would have to buy more expensive 4x1070. Sure, it varies, but in my case 1080 is a better fit, even if I expand to 6 card rig. The 1080ti is out of my financial capabilities though.

So, long story short bought 3x1080 on ebay recently. They were about 20% more expensive than 1070s, and easier to find.

As the rig is still being built I'll probably jam the cards directly on the gigabyte h110 d3a motherboard for the time being. Also waiting for the riser delivery. Cooling is not a problem, it's winter and my cellar is around 5-10°C at all times.

it all depends on how much you have to pay for the GPUs, I think that a GTX 1060 under 200€ is unbeatable. That's 24MH/s for 200€, that's "only" 8.33€ per MH/s. With a 1080, you will pay at least twice that price if you're lucky and you won't get twice more hash power.

If you buy a 1080 with the intent of mining ETH, you've already failed. Having that GDDR5X memory isn't all that great for ethash.

 You DO get close to twice or sometimes a hair MORE than twice if you don't insist on pointing a 1080 at an algorithm (ethhash) that is IS NOT WELL SUITED FOR.

 You can also get a TON better efficiency on some algorithms - ZEC in particular a 1060 (per ALL of the postings I've seen) struggles to hit more than 3 sol/watt while a 1080 easily hits 4.

 For ETH, the 1060 is a better option - but that's NOT the only option out there, and judging a card JUST on it's ETH performance is STUPID.

Given that you're already considering most of the NVIDIA GTX lineup, also consider looking into the 1050 TI. In my local cryptomining scene, where the 1060,1070,1080 are now rare or overpriced, people have now resorted to using 1050 TIs in sets of 13 GPU rigs. They do around 15 MH mining ETH and the 13 GPU rigs can do around 190-200 MH which is not bad once you consider the power consumption is low as well.

Has anyone here used 1050TIs as well?

Lucky you!
In my country (now):
1060 3GB ~ 350$ (Palit)
1070TI ~ 800$ (Strix, NA - old price)
1080TI ~ 1180$ (cheapest overheating MSI Armor)

Rest of the list is NA everywhere even on less reasonable prices ATM :-/
I thought about getting new rig with 4x 1080ti, but 4700$ for cards only...

edit:
Even 1080 models are available only with water cooling, LOL.

Depends on where you live and your power requirements.

An 8 x 1060 rig pulls about 800 watts from the wall so I can run two of those rigs in one outlet.
An 8 x 1070 rig is at around 1200 watts so you can only run one per outlet.

So for example if you only had two outlets available for rigs, you could run 4 x 1060 rigs or 2 x 1070 rigs. This is for my electrical setup.. you have to see how much power is available to your outlets and then do the math on what's cheaper.. more efficient.

 800 watts is EXCEEDING safe operating limits for a common 15 amp 117 VAC circuit that is running 24/7 if you are using 2 such rigs on that circuit.

 15 amps less 20% REQUIRED DERATE for 24/7 operation = 12 amps, 2 rigs is 6 amps per or 660-720 watts MAX depending on the actual voltage at your outlets.

 You can probably get away with it in the winter when temps are cold, but come summertime you WILL have issues and WILL be pushing temps to an unsafe level, especially if your breaker box is in an area that isn't air conditioned and VERY cool.

 8 cards per rig is also an uncommon number - 6 seems to be "the norm" as there are very few motherboards that will support 8 cards while those that support 6 are common.



 

Totally agree!

I have a GTX1080 which I got at the same price as a gtx1070 and I am doing 490-500 sol equihash with the power limit at 60% (Could do more if I rise the power limit). IMHO if you can get a 1080 at the right price is worth it.
Yes it has limitations mining ethash (same hashrate as 1060).
In another algorithm (can't remember if cryptonight or neoscript) is as good as a 1070. On everything else is superior to a 1070 where it should be.

On top of that, it has an amazing gaming performance and a very good resale price.

IMHO, based off of performance over a large range of algo's and future resale value- the 1080 ti.  Also, you can undervolt the 1080 ti if power consumption is a concern as this seems to work better to drop power consumption and maintain performance than the sliding meter.

Seems 1070 is best from the balance between Performance and Price.
Im wondering 1070 is worth to pay for tiny miner.
Now Im with 1060, for second card, 1060 6gb is affordable for beginner, but 1070 seems worth to invest for 2018mining. mmm...

What to go with for Equihash mining (at this moment):

1 x EVGA GeForce GTX 1080 Ti SC2 GAMING, 11G-P4-6593-KR, 11GB GDDR5X, iCX Technology - 9 Thermal Sensors & RGB LED
760e

2 x GIGABYTE AORUS GeForce® GTX 1070 8GB GDDR5 256 bit, DVI-D, DisplayPort, HDMI
420e each = 840e both

if you would build a 8 - 13 gpu rig with nivida and low power consumption costs, would you go with the 1070 or 1080? Ti is out of budget, think it's not worth it when you work with so many cards. No card is in stock at all are overpriced, so not that much room. But if you would have to buy, 1070 or 1080 to go? And EVGA is still the best brand?

Sorry mate! The electrical can run 1800 Watts .. I push about 1550-1600 on it and it’s fine. Zero issues.

As far as running 6 cards being the norm. No way. Maybe it was the norm in 2014 but it’s a waste nowadays. I run 9 gpu’s on my boards. 7 pci slots and 2 off the m2 adapters. Why buy a 6 slot pci motherboard when you can buy a 7 + 2?

Try reading the NEC sometime - the code REQUIRES a 20% derate for 24/7 operation for SAFETY reasons, and a 15 amp circuit is only legit at 1800 watts *IF* you are seeing 120 VAC OR MORE at the socket, which is bloody RARE.

You WILL have issues once the temps warm up, unless you keep the breaker box in an air-conditioned room - and you ARE pushing the wiring and the outlets THEMSELVES past safe operation conditions unless the outlets are NEMA 5-20 AND the wiring is sized for 20 amps or more (12 AWG).
You might have issues with the breakers even if they ARE air conditioned, as your rigs will soak a little more power when they get warmer.

Yes, you might get away with exceeding specs for a while - but when your place burns down due to overloading your circuits, you have only YOURSELF to blame.


M.2 to PCI-E slot adpapters have been widely reported to have issues - some get them to work, others never manage it.
They also add cost per slot, though I'm not sure how much or how little.

Also, motherboards that have 7 or more PCI-E slots tend to be EXPEN$IVE - adds significantly to the cost per GPU, and needing fewer CPUs and RAMS doesn't always add up to less expensive if you're paying $50-$100 MORE per motherboard.
You're also going to lose more hashrate for longer when a bigger rig goes down - might be enough to more than make up for any "cost per slot" savings IF ANY that a bigger rig MIGHT manage.

It's a tradeoff - I prefer the smaller rigs because they fit SAFELY into my infrastructure, your rigs are NOT a safe fit at 2 per 15 amp circuit.

1080 better

I agree.. 1080 better.. at current prices.. half the price of the 1080ti.. and much more then half the hash rate.. im about to get some :)

My opinion is that the 1080 is a bad decision, especially if you can get the 1080ti for only an additional few hundred bucks. The 1080ti has better hashrate for density and has the best power efficiency ratios. Not to mention that it has more resale value in the long run.

I highly recommend that you do the math first.

I have all of them except 1080, the last that i bought was 1080ti. I think it is worth every penny, for some algos it gives twice more then 1070.

I'm doing the math now in a excel spreadsheet, i'll post it here, with current prices from newegg/amazon.

I know this is super simple... but please consider I just need 2 card to finish a rig that has 4 1070s... and my energy cost is a fixed monthly one...

So even if the 1080 is not the most energy efficient.. from this data I got seems to be a legit choice to finish this one rig.
