Hey folks,

there is a Guide (http://www.coinminingrigs.com/how-to-build-a-6-gpu-mining-rig) that says "28mh using only 90 watts" with a GTX 1070. Can anyone confirm this? I have a GTX 1070 running and it consumes ~150W (=max it can do on stock) at a rate of ~26MH/s for ether. I wonder how you can get a higher hashrate and actually use LESS power?

Is there anyone who can provide some tipps about this?

Cheers Zuop

same here... 26 mhs at 80 tdp (120w or so) on a 1070 gigabyte g1

i gave up on optimizations for eth

yeh i can confirm it..
i have done it before as ether is memory hungry you achieve it like this:

core clock -200mhz (or as low as your software allows)
memory +1200mhz (note not all 1070's can achieve this my g1 Gaming with samsung can tho)
tdp @60% (i think was a while ago since i used my 10x for eth mite even be tdp @55%)

Best Regards  (note even with default settings if you push the memory to +1200mhz you can achieve (30-32mhs)but thats @150-180watt..) 28mhs@90watt is better !

It also depends a lot on the brand of the memory on your specific 1070 - some just works better, which is critical for a memory-hard algo like ETH uses.

 I've NEVER seen a 1070 that could manage +1200 in afterburner (but I don't think any of the 1070 I have use Samsung - even my Gigabytes)
 With that said, bumping memory clock up as far as you can with reliability, bump power limit way down, and bump core clock down is the way to go on tweeking a 1070 for best ETH mining efficiency.

Hey Nemo &QuintLeo

thanks for sharing your knowledge.
I have to invalidate my 150W statement, I just realized there is a power monitoring in afterburner.

I tweeked around a bit and made some observations:
* Reducing the Core Clock can lead to "unstable" graph, could this damage the card when used over a long time?
(almost got a heartattack at this point because as I wrote it I got black rectangles all over the monitor :D )
* Increasing Memory Clock results in a higher hashrate by higher power consumption
* Reducing Power Limit can limit and decrease the hashrate

I have my PC plugged in into a power analyzer. Everytime I change the Power Limit for 5%, the power analyzer changes for about 9W but afterburner just changes about 3-4W. I don't know which to trust more :D

Also if I set the Power Limit to 60% it doesn't really matter what I change on Core and Memory Clock, it feels like the hashrate is capped by the 60%. If I set it to 65% with same clocks the hashrate increases.

I played around for about 3 hours now, but I still didn't find my best suitable settings, I have roughly ~28Mh/s @85-90W now :D

I tried with under 60% Power Limit, -200 Core clock and increasing Memory Clock but this somehow just got me around 25Mh/s. After a while with MemClock on +650 I got graphic issues so I'm not comfortable with this at the moment.

Always trust the "at the wall" measurements made with a real power meter over any software solution.

i find 1070 being very touchy about temps...dont see anything like this with 1080ti

The measurements at the wall shows ~160W for the whole PC with Monitor turned off.

I'm still interested if someone wants to talk about GTX 1070 (or nvidia) settings to get the most profitable setting :)

i also thinking that in the past, but the last software for temp monitoring is really good, they improved a lot, you have nvidia with smi which is not so far away from telling you the true wattage, maybe 5% off, and the corsair link also is very precise, they are more comfortable than wattmeter

Most 1070 can do over 31 MH/s @95W at the wall. But mininig eth with 1070 is lost cause anyways.

 That's why you bump up the fan profile - ALL recent video cards prioritise "quiet" over "cool", with the early EVGA 1070 models being a POINTED example in going way too far that direction to the point they were having some of them fail due to overheating BECAUSE the fan profile had the fans running so slow they couldn't respond to load spikes fast enough.

 1080ti tend to have better fan profiles to start with because the makers *KNOW* they are going to generate a lot more heat so they bumped the fan speeds up a lot higher to start with than on a 1070 - and if you pay attention you will note that most makers have the SAME cooling solution available on their 1070 models as on their 1080 and 1080ti solutions, except for some of the LOW END 1070 models with cooling solutions that can't handle a 1080Ti at all.


 IMO any miner that doesn't have the fans on his GPUs running at 90% or more by the time the card gets to 80C (and preferably 70-75) is DEMANDING to have their card overheat and die.



 As far as "most 1070 can do over 31Mh/s" - I call BULLSHIT on that one, NONE of mine have ever managed more than 30 no matter HOW HARD I pushed clocks, even at 180 watts much less 95.
 ETH depends WAY too much on low memory latency, and that VARIES WIDELY depending on the brand and sometimes the specific chips of the memory in a card.


 Mining ETH on a 1070 isn't a lost cause.
 It IS still very profitable, much more so since the recent ETH price runup, just LESS so than other options.

 
 NVidia-SMI is nice, but I've seen it get confused and "off" often enough that I don't trust it to be entirely correct.

Besides that I already had the 1070 for gaming purposes, I think the 1070 is great for mining if you're paying more for electricity than most miners because of the low power consumption. The high initial buying price for a 1070 should not be THAT relevant if you mine long enough is it..

Hi Guys

Need Some help please

I have a Question which I have been Trying to Figure out but cant get the calculations right!

The Rates seem to be all over the place and some saying the 1080 is worse then the 1070 for mining?

6 x GTX 1060 3Gb or
4 x GTX 1070 8GB (500$ More then 1060) or
3 x GTX 1080 8GB (150$ more then 1070)

Thank for the Help in Advance

Mining zcash:

1. 275*6 = 1650 sol/s ($22.34 per day)
2. 430*4 = 1740 sol/s ($23.56 per day)
3. 3*500 = 1500 sol/s ($20.31 per day)

The rates vary from coin to coin. The 1080 is bether in siacoin and decred.
Most ppl have the gtx 1070 so the code is normally optimized for the gtx 1070, but the best bang for the buck is the gtx 1060 3gb with private kernels.

Best bang for the buck has to take in the total system cost though, not just the cost of the cards themselves.

 That's where the 1060 takes a noticeable hit - it's efficient on a "per card" basis, but the total system cost to hit a given hashrate needs quite a few more systems so the "per card" basis ADDING IN THE ADDITIONAL SYSTEM COSTS gets a lot closer.

 It might still be "the most efficient" overall but it's not going to be by a huge margin if so, unlike if you only count the cost of the card itself where it is pretty dominant on ZEC vs the 1070/1080/1080ti.

 You also left out the 1060 6gb - which has been reported over 300 sol/s with EBWF but doesn't cost a lot more than the 1060 3GB models.




 to Bakes007 - the rates vary some on ZEC mining because the cards themselves vary (FE cards might be an exception among themselves).
 There is no such thing as "any 1070 can do any specific speed at any specific wattage used" because of variations in how the third parties build the cards, and the parts they use, ESPECIALLY MEMORY.
 For a specific example, my Gigabyte 1070 full-length cards (180 watt TDP) have "stock" clocks noticeably higher than my EVGA 1070s (all long card, 155 watt TDP) or my Gigabyte "ITX" short 1070s (155 watt TDP), and seem to cool better, so they can be pushed up to 430 sol/s fairly easily where the EVGA cards and the ITX Gigabytes have to push hard to get much over 400 sol/s - this is in systems where the rest of the system is IDENTICAL (in fairness, the ITX cards always get inflicted with a PCI-E 2.0 "16x" slot that only has "4x" lanes wired to it, but for most cryptocoin mining that's NOT an issue or "riser rigs" wouldn't be so common or work worth beans).

 Memory brand also has an effect, as some brands will let you clock the memory a LOT higher than others (more of an issue mining ETH but it's noticeable on ZEC).

 My only 1080 is also a long-card Gigabyte, and can push 500 sol/s pretty easily. Tradeoff is the cost - $489 for that one ($499 for the second one I just bought) vs $379 or $389 for any of my 1070 cards.
 When you factor in the cost of the total number of SYSTEMS and the total SYSTEM cost, the 1070 and 1080 get a lot closer on hash/$.


 I too have noticed the efficiency of the different cards changes from one coin to the next - the 1080 I have can do quite a bit over 600 MHhash/s on Skein, the 1070 Gigabytes might manage 500 or so and have to push harder to get there, which on a raw card basis gives the 1080 slightly better hash/$ and even more so at the system level.
 On ETH, though, the 1070 Gigabytes and 1080 Gigabyte have almost identical performance near 30 MH/s, indicating that the extra cores on the 1080 are barely enough to overcome the higher latency of the GDDRX 5 memory on the 1080 (even though the memory speed is HIGHER, the latency is worse which is a MAJOR issue on ETH) - and the EVGA cards only lose 0.5 MH/s at most to the long Gigabytes despite the almost 10% lower core clock on the EVGAs.

 The reason AMD is dominating on ETH is that you can match the performance of a GTX 1070 almost identically with a minor BIOS mod on the 480 (there are no tools for BIOS modding a NVidia 1070, other than trying to flash the card with a BIOS from a different model 1070) on hashrate and VERY close on power, while paying ('till the last week or so) a bit over HALF THE PRICE for the card.
 Even bone stock, my pair of Sapphire RX 470 will manage 22 Mh/s on ETH - and only cost me about $170 each new from Newegg (I got them to match the deal on their own EBay site under their price match guarentee but they would have still only been $183 or so otherwise WITH shipping) - which makes them a TON more efficient on a Hash/$ basis than any GTX 1070 has ever been.

Thank you so much

That helped me alot!

I would love to get Radeon but they are sold out in the entire country (South Africa) With some company's having back orders of 100 Cards!

So Zcash and GTX is the only way for now to start mining Altcoin.

I'm going to go for the 4 x GTX 1070 8GB

Although the 6 X GTX 1060's are much cheaper and the $ per day are not much less, I fell like the Card is getting old now adn im going to add 2 more 1070's in the Future.

Ok so I dont mine ETH, but i switched and setup my cards just for you. Here is the screenshot of my 7x1070 rig. And please do not talk bullshit to people just because of your extremely low knowledge of the nvidia cards ( judging from your previous posts where you are lost tbh). Just for your knowledge rising TDP will not give you any more MH/s in eth.
http://imgur.com/a/oX9Wl

Oh and one more thing, calculating profitability of nvidia cards based on zcash or eth is wrong. Every day you mine zcash or eth or any other default coin on what to mine you are loosing your ROI to AMD cards.

lol your screenshot is funny 1 minute of mining if i try that i can get 34 mhs out of the 1070 but after 20 seconds it crashes i bet your system will freeze after some time wahts your clock speeds and undervolting settingsyou do that at 950mv @ 2100 mhz ~ 4400 mhz ram more than 29 is not stable 4 me sry 4 my bad english hehe

These settings are stable and can run days. I wont mine eth for one day just to show you a screenshot sorry. As I have said earlier you do not want to mine eth with nvidia :)

Also please show me a screenshot of 1070 doing 34, even for a second! Thanks! :)

Quite nice Results, what Kind of Cards are that?

i tried both but the wattmeter is only 2-5% more accurate, but it's not worth the effort to plug that just for 3% difference, i prefer measurement with software much more confortable for me

This rig is: EVGA GeForce GTX 1070 SC GAMING ACX 3.0 Black Edition 8GB DDR5, 08G-P4-5173-KR, its the cheapest EVGA cards out there :) at least in my country.

Hi Kompik.  What are your exact settings to get that performance in your picture with your card? Thanks, I really appreciate it.

 What model of cards are those, what settings, how LONG can you run them at those settings without crashing, and what brand of memory?
 If the memory is Samsung, THAT is why you're achieving those *BETTER THAN NORMAL* ETH hashrates - most 1070 cards do NOT have Samsung, they have lesser brands like Micron or Hynix which limits their potential STABLE memory overclock a lot and doesn't let them get as high of hashrate as a result.

 ONE MODEL does not qualify as "most", even if your cards CAN handle hours at the settings you were using.


 I never said ETH was the best option to mine on NVidia - try reading what I posted where I SPECIFICALLY STATED it is very profitable "just LESS so than other options."

OK, now I am into SERIOUS disbelief.

 Some of my 1070 cards are THAT SAME IDENTICAL EVGA SC model - and they do NOT achieve 31 Mh/s on ETH, they do 29 or a bit LESS at the highest memory overclock they can handle with stability (+500 in Afterburner) for more than a few minutes - I did try them early on at +600 but it was crash city consistantly in 2-10 minutes, and +550 was crash city in less than an hour every time.

 I do concede they are low cost cards - EVGA's second-lowest cost 1070 per their own website pricing.

 So tell me, just HOW are you supposedly getting YOUR cards of the SAME identical model to hash at 2Mh/sec faster while keeping them stable?

Would be possible to modify ddr5 timings on 1070??
There is a set of bios tools??

Thank you.

Actually those are all micron memory cards. My samsung cards ( I have very few of them :( ) can do even 32MH/s. But to be honest, only the first micron memory brands had issues. Nowadays the difference in perfomance is much smaller.

All in all, almost all of my cards can do over 600 and be stable on memory forever (some can do even 700 to be stable, having problems with Palit and ASUS cards - not stable on more than 500Mhz). Maybe it is only one card in a rig that is pulling the whole rig down? Also having high GPU clock on eth can actually jeopardize the performance. Try to hit 1750 mhz at max on the core while having as much as memory OC as possible to be stable.

Not possible.

 I've tried all 3 cards in a single-card rig - same limits on memory OC, no matter where I put the core clock.

 I see better ability to bump the memory up on my Gigabyte cards - even the mini-ITX model cards I have - which is part of the reason I stopped buying EVGA even when it's on sale at the same price.


 Academic point to me anyway by now, been probably 2 months since I had a 1070 pointing at ETH for more than an hour or two of testing.

Okay. Don't mine eth it is a loser coin.

Mine Zec or skein

Zec settings

60 to 70% tdp

150 to 250 core.

-500 to 0 memory

75% manual fan

Use ewbf 3.3 miner put --pec at end of bat.

That gives you sols to watts

Goal is 4 sols to watts for 1070,1080,1080ti

Good luck

Yeah I was able to get 31 pretty easily too and this was with Micron memory EVGA, but much more profitable to mine other algos on 1070 ETH is kind of a waste with that card.

i was getting 33Mh but you need serious OC on ram like 800+, still the wattge remain around 100watt, very efficient and better than amd, but amd stillw in due to hash/price, better option are out there for nvidia than ETH

I never get 100W.
Always about 120W per Card. (MSI GeForce GTX 1070 ARMOR 8G OC with Micron Memory)

Wattmeter says 470W from the wall.  :o
Only 1 ssd connected, nothing else

Setting:
60% tdp
200 coreclock
0 memory

Temp: GPU0: 56C GPU1: 58C GPU2: 48C
GPU0: 419 Sol/s GPU1: 431 Sol/s GPU2: 422 Sol/s
Total speed: 1272 Sol/s
+-----+-------------+--------------+
| GPU | Power usage |  Effecincy   |
+-----+-------------+--------------+
|  0  |    116W     |  3.61 Sol/W  |
|  1  |    119W     |  3.62 Sol/W  |
|  2  |    120W     |  3.52 Sol/W  |


And very often "Connection to GPU1 lost"

Now it's finding only 2 cards, even after reboot.
Gonna send them back and stick to my old 280x's it seems  :'(

Does this screen belong to EBWF Zcash miner and is it "--pec" command?

What command should I run to get this info in the miner?

Thanks.

I am running a similar setup with similar settings, but I am not getting that hash rate -not even close.  I am getting about 385 sol/w per card.  But I draw a little less power at 110W, my efficiency is a little lower but acceptable.  I don't understand how you are pulling 470 at the wall.  You should only be seeing 400 to 410W.

I get 31.9 with out batting an eye.

I saw 32.9 once. Never got there though. Maybe it was a fake...

I know nvidia does better with equihash, however on whattomine ethereum still frequently comes out as the most profitable coin to mine when I plug in the figures for an nvidia gpu. I'm mining other equihash coins at the moment but ethereum is/can still be the most profitable.

 Hashrate 31.06 MHash/s

I have four 1070s, they all do close to 32 MHS (like 31.7).  cclock -400 mclock +683.  I can push them a little over 32, but I don't like to push my cards to the edge, because I want them to last.

They consume between 100 and 125 watts, depending on the model.  Three of them require 8pin+6pin and generally are a little less efficient, even at 50% TDP, though one only uses 115W.  One is a single 8-pin and uses only 100W (31.5 MHS).

I did get a dud a while back.  For whatever reason it wouldn't go over 27.5 MHS no matter what.  But back then zec was still pretty profitable.  So I mined zec on it until recently and then sold it to a gamer for close to what I paid originally.

I'm not overclocking my graphics cards much.
TDP 85
cclock +100
mclock +500.
I have ~ 31 MH/s

Asics on the Equihash algorithm killed the profit on NVIDIA. Now GTX 1070 is equal in performance to RX580 and RX580 is much cheaper.
Who has ideas for mining at GTX 1070?
