Hi, what os are you using? If it's windows you can use msi afterburner to do the undervolting. (It's an all in 1 software (you just can't modify the gpu's bios in there)

Hi, I can currently get a 1080 for 500usd brand new. Which I am planning on building a 7 gpu rig with them. what OS/miner should i use? I was initialy planning on using simplemining but for maximum profitability I should be mining Skein which isn't in there. So what should i mine?

P.S. I was thinking initially of getting 7 1070 but for 70usd and you get a 1080 which will have a higher resale value... So i am not really sure which path i should walk.

If you are looking strictly at Ethereum mining then go with the 1070's.  All other mining I would go with the 1080's as you get better hashrate for about a better cost ratio and the resale will likely be much higher.

I'm currently running 7-1080's and 1 1080Ti and make on average about .023 BTC per day doing auto-exchange at Zpool either with their built in multialgo or using Multipoolminer.  You might be able to do better on specific coins, but only if you are willing to deal with trading them on the exchange yourself.  Life for example when Digibyte spiked I was pulling in about $120/day for all my rigs, but that was only if I dumped the coins at the high point.   You have to decide if you're taking your profits today or holding the coins you mine until the time is right for them.

Here is example hashrates for a 1080:  This is a single 1080 Zotac AMP edition

https://i.imgur.com/hwuXWIT.png

This is my 5 - 1080 rig - 2 Zotac Amp Extreme Edition, 2 ROG Strix, and an EVGA 1080

https://i.imgur.com/ghunKhp.png

There is quite a bit of variability in what hash rates you'll get out of each cards including power draw.  I notice those Zotac Amp Extreme Edition pull about 15% more hash, but also consume like 50W more in power.  The 1080Ti gives roughly about 40% more hashrate for about 25% more power consumption and 30-50% more cost. You have to decide if that is worth it to you.

Pure ethereum mining I'm seeing roughly like 20-25Mh per 1080 usually with no overclocking and setting a Power limit of 80%.  Setting power limit to 100% gives like 3% more hash, but consumes like 20% more power.



I think you basically covered it, I guess the question for miners now is (other than what coin), do you go with 4 1080s (or 3-4 1080ti) or 6 1070s.


What can your motherboard handle is important also, I'm leaning toward 4 1080s, I just don't know if it's worth it to go with 4 1080ti...

Hey, i got a guy helping me and i am helping you. So all is well. Like i said on windows 7 you can easily use the msi afterburner to fine tune your gpu without doing bios mods. Bios mods can help further but when just getting started the msi afterburner works well and is user friendly. Just do the modifications little by little. but you shouls be able to get -50mv easily

Hi, i also have 3 gtx 1080 founders edition and i have some questions:
1: all 3 gpu's are currently running at temperature 82 c and they make about 9$ per day, Is the temperature 82 ok ?
2: if i keep them running 24h, aprox how long will they last ?
3: does overclocking has effect on how long the card will last ?
Thank you for help

In MSI Afterburner just drag the Power Limit to 70%. Doesn't affect hashing too much but runs the cards much more cool.  Saw somewhere to set the temp limit to 80c.

Load up afterburner and set the power limit to 75-80% and see if it has much of an effect on your hashrate.  I think you'll find you only lose a few percent, but the temps will run much closer to 65-75c.  Overclocking can shorten the life, but I think it depends on the temp more than anything.




I think you basically covered it, I guess the question for miners now is (other than what coin), do you go with 4 1080s (or 3-4 1080ti) or 6 1070s.


What can your motherboard handle is important also, I'm leaning toward 4 1080s, I just don't know if it's worth it to go with 4 1080ti...



I'd say that if power costs are a concern I wouldn't go with the 1080ti's  They will run a good 250W each so you'll need a big power supply for them.  The 1080's are going to run more like 175-200w at the top end.  Other thing is the 1080Ti's will likely hold above the $500+ resale value for a good long while, whereas I'd expect the 1080's will be closer to $350-400 after about a year, maybe less if mining dries up.  Either way you'll likely have the cards paid off in 2-2.5 months of mining at current rates.

I'm running all mine on Windows 10, but that's just because that's what I had handy.  Not sure if the OS would affect my rates that much or not.  I might try reloading one with Win7 and see if I get different results or not.  I might actually try Linux too since that is likely much lower performance requirements and I could easily put that on a thumbdrive and try it out.

Damn this is perfect and exactly what i was looking for thank you so much XD
Can you elaborate more? As to what OS and miner you use to mine with those 1080?
Also i wasn't planning on mining ethereum but more like you said a multi algorithm on zpool or something.


Those benchmark outputs are from Aaronsace's MultiPoolminer.  The most recent commits to Github have the stuff to run on zpool, but not without some modifications as to what algorithms you want each of the miners to launch.  You can see in the picture on the left it lists which miner is associated with which algorithm and the hashrate that I'm seeing from it. 
https://github.com/aaronsace/MultiPoolMiner/releases

I used to say the easiest way would be to use the batch script method that Nemo's Miner pack offered, but he's taken it down and replaced it with a zpool version of Multipoolminer.
Here is a link to his old pack that includes the miners:
https://mega.nz/d772a928-82f0-4a77-a7e2-bcc334843571

Not sure how long that will last though.  Otherwise the easiest by far is just download nichhashminer and use that since it is set it and forget it.  Although my experience is you lose about 25% of your potential earnings compared to other methods.  I prefer zpool over multimininghub at this point only because it seems like MHP penalizes you quite a bit for hopping around on the algos.

How do you run this benchmark with MultiPoolminer? I would like to get a benchmark for my card. Thanks.

I'm pretty sure Ethereum is the most profitable right now.
awesome rig, should do well mining for ETH.

 1080 is NOT a good ETH mining card, the GDDR 5x latency kills it's hashrate to where it's worse than a 1070 and IIRC a hair worse in some cases than a 1060 3GB.

 ZEC and offshoots like ZTC/ZEN/HUSH, the Skein and Groetsl coins, are all much more profitable options for the 1080.

 For ETH, the 1070 is definitely a better option - 28+ Mhs with even a mild memory overclock and if you have good low-latency memory or can overclock your memory a LOT you can get over 30 Mh/s.
 It's been pretty close for the last couple weeks between ZEC and ETH on profitability for a 1070, though there have been more profitable options most of that time (see the 1080 list).

 Down side - current pricing of the 1070 is starting to push hard into lower-end 1080 territory, and availability is getting VERY marginal.
 It seems like the 1070 is what the big-farm ETH miners are starting to go to when they can't get the good RX cards at a reasonable price.

What's the inside of your case look like?  Seems like you likely have bad airflow.  Although your fan speed looks like it is pretty low for that temp.  I'd expect with the default settings in MSI to have your fan speed at like 75% when you are at 80C+

Click the settings and then the Fan tab and check the custom curve and raise your fan speeds for higher temps.  If you take it off auto and set the speed to 100% does the temp come down?  Also turn your machine off and make sure you don't have a broken fan blade.  Even one fin missing caused one of my cards to have 20C higher temps compared to my other cards.  Finally took the card out and realized it was missing a fin off the middle fan on the card.  Replaced the fan and it came down to normal ranges

@business360 remove your fan speed from automatic to manual and put it at 75% that also should help.

I set the fan manually at 90% and the temperature goes down to 72-75% from 83%.
If you run this gpu card 24h with fan at 90%, how long its lifetime can reach ?

Oh its' one of those Mini-ITX cards that's why it runs much hotter.   Running the fan at 90% isn't going to burn the card out any faster, but the fan might fail eventually.  Plus they're usually much louder above like 75%.

Not much you can do with a card like that other than maybe put a fan outside your case blowing onto the fan from outside.

Not sure if he is talking about the one on the top or the one in the bottom (if its even a gpu??)
90% is a little high on the gpu fans but it's still ok. Are your case fans running at max? Those 12v case fans are made to run at max for 3-5 years easy. (I still have my stock case fans from my first coolermaster case from 2006 those fans have been running at max for 11 years...) Or if your case airflow is bad maybe changing the fans to better fans would be a good idea. (I like the cougar fans, 16dba, 65 cfm and high static pressure designed for long life)

the bottom gpu is older gtx 780 but i'm only testing the upper one (gtx 1080 fe). With fan set at 90% after 10 minutes the temp stays at 70c stable. With default settings lbry generates 7-8$ / day on nicehash pool. I can get very good prices on gtx 1080 fe in bulk but i'm worried about gpu longevity. If the fan will eventually die, is it cheap to replace it ?

@business360 remove your fan speed from automatic to manual and put it at 75% that also should help.

 Automatic is fine if you set up a CUSTOM fan profile - stock fan profiles are way too much about "quiet" and not enough about "keep the bloody card COOL".

 I generally use a profile as follows:

 80C       fan 100%
 70C       fan 80%
 60C       fan 60%
 50C       fan 40%
 40C       fan 20%

 This profile works well on any video card made in the last 6 years or so that I've had access to (which is a pretty wide range on AMD but only the last 2 gens on NVidia).


 The GTX 1070 Gigabyte ITX doesn't run all that hot, if you keep the airflow path to the fan clear AND have enough airflow.
 I've got a few of those....


 One thing that might help - remove the slot metal piece from the "empty" slot between the ITX card and the power supply.
 Also, that back fan is sucking cooling air AWAY from the video cards - it would be better to have it in the front pushing more air INTO the case.

 Too many cases spend too much time and effort on keeping the CPU area airflow high, and neglect the GPU area VERY BADLY - wasn't a bad concept 10 years ago but in this day and age of a single GPU often pulling a lot more power than the GPU, it's BAD DESIGN that you have to work around by smart setup of your fans to push more air through the GPU area, AND leave an "exit" path FOR that air.

82c is pretty high. I would recommend undervolting to lower that to 70c at least. 60c-65c is best.
At 82c the cards will last a year maybe.
Not true. 82C is a perfectly safe temp for modern cards

82c is perfectly fine for modern cards that is 100% true. But we don't use them in regular ways... We push them at max for 24/7 for a few months at a time. And for that kind of treatment 82c is high. 70c is normally the max you would want to do 24/7. 60-65 is best, me personally I prefer to try and keep them 55-60 but that's my personal preference.

Thank you, appreciate your help. I run ccminer lbry with default settings, no overclocking of gpu. I didn't see any settings for temp, How can i lower the temperature ? Thx in advance!

Hi, what os are you using? If it's windows you can use msi afterburner to do the undervolting. (It's an all in 1 software (you just can't modify the gpu's bios in there)
Linux sadly i don't know them yet XD
I'm using 7 -64 bit.
Thanks for help. Its nice to see people like you helping others Smiley

Hey, i got a guy helping me and i am helping you. So all is well. Like i said on windows 7 you can easily use the msi afterburner to fine tune your gpu without doing bios mods. Bios mods can help further but when just getting started the msi afterburner works well and is user friendly. Just do the modifications little by little. but you shouls be able to get -50mv easily

The biggest farms in the world are all NVIDIA. A bios mod require a crack of the driver.

If you have enough monero you can ask around @
