Trying to monitor my temps/fan speeds on ethminer with the command "-HWMON" ; however, it continues to give me an error saying it's an invalid parameter. Does anyone have the command to get ethminer to report temps/fan speeds? I know the "-RH" command works to give reported hashrate, but I can't seem to get it working for temp/fan speeds.
Actually I am using Claymore's ETH miner in single mode. This night I tested ethminer 0.13 and found that it outperforms Claymore's one a little bit (even not counting the devfee). But I like to monitor it via API using own tools. I surprisingly found that latest ethminer is compatible for miner_getstat1 API call, but it requires CUDA 9. Older version for CUDA 8 works well, but it does not yet provide the same telemetry. That's the reason I want to upgrade. Newer version also works in OpenCL mode but hashrates are much lower than in CUDA mode.
does this mean that you can monitor temperatures/fan speeds in ethminer?
Can I run the EthMonitoring.com Linux client in the ethos? I also would like to know whether anyone managed to get all 18 gpu running with Asus B250 mining expert mobo using ETHOS
I don't know if you can run it on the actual OS per se' but you can if you run the EthMonitoring app on a separate computer (in windows/mac/whatever) and add the IP for the rig running ethOS, it will show up on your dashboard. Kind of pointless to pay for EthMonitoring though since ethOS provides it's own remotely accessible dashboard.
i got 12 gtx 1070 EVGA SC2, all my cards have ETH 31MHs but the last one has 26MHs... what could it be ? I used same setting for all. This card did 30 on windows...
What brand of 1070? Also what's the powerlimit for that card?
EVGA is the brand
I set power 151 , mem 1400 and clock 100
I had that issue but that's because I was running the PL too low for one of my 1070s. After bumping up the PL to 120, it hashed at 30 mh/s no problem. What type of PSU do you have running these cards? Make sure there is enough juice going to it.

Your math doesn't make sence in real world. Either he run his 1070 at 100 or 150 wats PL, the hashrate for ETH will not increase, it will remain at 30-31 MH/s. So he is effectivly saving 50 watts per card while getting the same hashrate, what's wrong with that?
There is exactly 0 chance that you can cut the power consumption of any electronic component and receive the exact same output. If you could, Bitmain would already have an S11 on the shelves that uses 1 watt. If my math fails to make sense to you, it's likely because you don't even math, bro.No one ever said the SAME exact output, so of course you're going to make assumptions to fit your (greatly warped may I add) perception.
150W gives me 31 Mh/s whereas 100W gives me 30.5 Mh/s so in all practicality it is essentially MORE EFFICIENT (as we've been trying to tell you) to do it this way. The only reason why I questioned if a lower PL was "bad" was based on what you guys were saying and making it seem like lower wattage was a "bad" thing. But I can see now that I obviously can't take what you say with any type of validity, but I guess people will firmly stand in what they think is correct even when they don't have a clue what they're talking about. So before you go making smart ass statements like the one below:
There is no part of me that will ever understand the idea behind taking 10 cards and intentionally turning them into 7 
Maybe you should at least try put forth a worthwhile post that helps instead of trying to belittle someone in a topic you are obviously less versed in.
Also back to my original question:
By the way, a little off topic, but do you guys think it's ok to run 12 GPUs (all 1070s except for 2 which are 1060s) on two EVGA G3 850W PSUs? I downvolted all of the cards and each 1070 is right around 100W/piece and 1060s are roughly 80W. Been stable now for over a week, just wanted to get some feedback regarding this setup.
Since when can a 1070 hit 58mh/s?
I don't do ETH (nor do I understand doing it with NV cards), but: https://www.youtube.com/watch?v=cdeA7s9SmRYThat's not real. It's supposedly a mod use to modify the REPORTED hashrate to make it appear higher than what the EFFECTIVE actually is. The video you linked is all a scam for $400+
See https://bitcointalk.org/index.php?topic=2145776.0
So now, back to your question, why is it detrimental to mine at 30% less power when the effective hashrate is the same as it would be on 100% power? And I mine ETH on NV cards because 1) it's more efficient. You are getting 30Mh/s on 100-110W with NV vs. 29-31Mh/s whatever the wattage is for the rx 470/480/580s which I believe was around 130s-140s when I looked into it a while ago. On top of that, you don't have to go through all of the BIOS mods with NV as you would for the Rx cards and risk the chance of bricking.
...Been mining ETH and my hasharates have been 30-31 per 1070. I never thought you could have a PL "too low" if it's within the supported wattage of the card. Of course, some GPUs, like the MSI 1070 Gaming X requires minimum 115 watts but some other 1070s can go to as low as 90 so that's why I say average is roughly 100W per card. It's bee stable like this for nearly 2 weeks now so I don't see why it's a big issue if it's stable?
I'll get my "DOH!", for mining ETH with that many NVIDIA cards, out of the way right off the bat.That being out of the way:
Granted, in the real world, the loss isn't 1:1; however, for ease of math, we'll pretend it is.
If you have a 150 TDP card and you down the output by 30%, then you have taken a 1500W set of cards and lowered them to 1000W. Now you have a 500W reduction in power that is the same as the total amount of power required to power 3.3333 cards at full power (for ease of math we will call this 3 cards). So, you have an effective rate of 7 cards and have 10 cards sitting on the rack. To what end?
Yes, it's at the lower end of stable, but what is the point?
Not counting the 1060s and your other rig(s) that make up your other 8 cards....
Even if my numbers are off by 1/2, and we pretend you paid wholesale ($375) prices for those cards, you have $624 worth of cards sitting idle the save $438 per year in consumption while giving up 49% of your potential earnings (by running cards at hashrates of as low as 30 when they can hit as high as 58).
It's something that makes less and less sense the more and more cards you run.

I am with @ComputerGenie. Is there a reason you are not running individual power limits and clocks? Worst case, I would remove the 1060's and just run the 1070's correctly.
Agree,
80 W for 1060 is not so low, but 100 for 1070 is too low,
what are your hash rates with 1070 ?
I run my 1070 rig at 125 W, oc 125, cc 600 getting 460-470 sol/s
and 1060 rig with 85W, oc 125, cc, 600 getting 300 sol/s

What do you mean exactly? I have a pretty small setup (~20 GPUs), so I just try to consolidate whenever possible.

My rig with 13 1060 had a very high cpu load. Moved power limit from 75W to 95W and load went down form 6-10 to 1.8-2.5. No perfect but much better.
Good call, Thanks a lot.
Will give it a shot.
Edit
Thanks a lot mate, you saved my day.
So I raised 5 steps at a time, at 85 load average get to 1.5-1.8, went up to 90, 95, 100 and load went up too.
So 85 is the sweet spot for me.
Code:
Load Average: 1.60 1.83 1.83
Happy...
so what was your PL and load average before modification?
Very rare... my rig has a g3900. I think a i5 should not get that load.
Exactly, That was making me mad.
now :
Code:
load average: 0.68, 1.27, 1.51
Ideal load would be <2? I just checked for my 1060 rig (x10 cards) and it's anywhere from 2.1-3.5 -- Should I bump up my PL (78W now)? Not really too familiar with linux, so what does a high system load lead to (i.e. instability, decreased longevity, etc)?
how hard would it be to incorporate a web interface that allows us to switch the coin being mined (e.g. similar to simplemining.net)? Just asking for pure speculative purposes as I know fullzero has done a phenomenal job with nvOC already!
Same PSU, too? You can tell if they are using identical power with:
Code:
nvidia-smi --query-gpu=temperature.gpu,fan.speed,power.draw,power.limit --format=csv
Hope this helps.
Same PSU too
Are all the BIOS settings the same? Same on the PCI speeds, etc?
Same bios settings
lol ... going crazy ...
Removed all cards and restart rig with only 1 card direct connect to motherboard no risers,
Same low speed, 18-19 MH/s on eth
do you know what memory types are on the other 1060s?
After a restart, one of my rigs has a few GPUs where the minimum fan speed doesn't get set - i.e. min fan speed = 40; however, 1-3 GPUs are spinning @ 32%.
Granted they don't go over their temp limit, but they're constantly within +/- 1° without the fan speeding up (I have max temp diff set to 2). It's totally random at times which card(s) are affected, so I don't think there's something intrinsically wrong with any of the cards (MSI GTX 1070 x 7). Any idea why this could be happening? Not a big deal, just wanted to make sure that this isn't an omnious sign for anything.

So for those who are now reaching the login screen and cannot login even when you type in your password. SSH into your rig and run the following commands:
Now everything's working back to normal. Not sure why it did that for me. Also, I don't know if the first commmand is necessary, it's just what I typed in initially so I included it.
Code:
sudo apt-get purge nvidia*
sudo dpkg --configure -a
sudo shutdown -r now
sudo dpkg --configure -a
sudo shutdown -r now

I'm getting similar errors as those above me have mentioned this morning where I reach a llogin screen asking me for my password but cannot login. SSH shows this error

I had intended to fully respond to all the posts on this thread today; but responding to pm's took much longer than I had expected and I have a few other things I need to do today.
I have read through most of the new posts here and will respond to them tomorrow.
