Topic: 4x Nvidia gtx 1070 Ti Rig pulling 755 W? What's you guys' specs? (Read 496 times)

I had a some spare time today, so I decided to temporarily slap together a test rig similar to the OP's setup.

I couldn't get it exact but very close and I WAS able to fairly duplicate the power draw from the GPU's to show that ZhashOS is using LESS power as I stated before.

I had to gather a few GPU's from other rigs to do this for the moment. This test rig is using a celeron G3930 CPU. Same as the OP's. I couldn't gather 4 1070ti's, but I was able to gather 2 1070ti's and 2 1070's. BUT I set all the GPU's to draw 148 watts in the ZhashOS SetupWiz application.

So my GPU's were drawing MORE than the 564 Watts the OP was drawing. I did this to make sure I wasn't using less from the GPU's.

I also took 16MP pictures so you will be able to zoom in via "Ctrl +" in your browser to see the details if you like.

OK, so 1st pic is showing ZhashOS booted into the GUI desktop and idling. It is drawing a mere 52 watts. Power actually bounced between 52-54 watts while I was taking some pictures.

2nd pic is showing nvidia-smi showing the 4 gpus idling but consuming 32 of the 52 watts ZhashOS is using. So theoretically bare naked ZhashOS booted would draw ~20 watts.

3rd pic is a closeup of the nvidia-smi screen showing a clearer view. As a side note, I just realized I left a dummy plug in GPU3, which ZhashOS thought I wanted to be in dual monitor mode and assigned some extra memory and power usage to it. I probably would have been 2-4 watts lower than the 52 watts at idle without it. Oh well, that's what happens when you rush.

4th pic is a closeup of the power meter for clarity.

5th pic is a closeup of the SetupWiz screen. Here you will see I set the GPU's 0-3 to draw 148 watts and set a mild overclock. This was a temporary test setup. I didn't want to spend a lot of time on tuning it in.

6th pic Shows it in action mining using EWBF. There is a window below the miner showing GPU measurements updating once every 10 seconds. Activating this is a checkbox setting in SetupWiz.

7th pic shows a closeup on the mining in action for a clearer view.

8th pic shows a closeup of the meter for clarity.

So this clearly shows ZhashOS is not just like any other OS. We heavily focused on power efficiency when we assembled this mining OS. So that ended up saving over 80 watts over the OP's setup even while we set the GPU's to consume slightly more power.

FYI, 83 watts x 24 hours x 30 days = 59,760 watt hours (~60 kwh)

60 kwh x $0.145 kwh = $8.70 savings per month. Of coarse it will be even more if you pay more for power.

We estimate our dev fee would be LESS than $1.00 for this rig for the full mining month. This IS a "Money Good" proposition and a excellent "value" in this bear market we are currently in.

Do you have any calculator showing this profitalibity? Whattomine does not have SUQA. What hashrate do you have?

Mine SUQA much profitable now 

Not only the cards, there are other components of a computer that consumes power. In that sense your device is perfectly normal.

The processor you mentioned alone consumes 51W of that 191W (755-564W). It's perfectly fine what your rig is pulling. However, as people pointed out you can still decrease this consumption a bit.

Well your power consumption is mostly from the quad GPUs and also in Linux the power consumption is silghtly greater than other OS. So taking everything into matter 755 W power consumption is kind of normal and nothing to worry about.

The cards are not the only thing in the computer that pulls the power. The extra 180W is being pulled by the CPU, RAM, HDD and the other components of the computer.

In all due respect Cairbarreira, You can not categorically "claim" Linux uses 5% more energy. I have provided photographic evidence from a disinterested third party that ZhashOS which IS a Linux based OS is using LESS power than windows on the same rig right here:

https://twitter.com/firstminingrig/status/1010449787802484736?s=19 (https://twitter.com/firstminingrig/status/1010449787802484736?s=19)

I can claim this because ZhashOS loads itself into a ram drive therefor needs much less CPU utilization to operate and has ZERO need for virtual memory and therefor is not hammering on a hard drive swap file continuously. As a side note because ZhashOS is loaded into a ram drive, it doesn't even need a hard drive and application loading and general running is much much faster than hard drive based operating systems.

Answer me this.... IF Linux uses more power than windows, Why are the hundreds of millions of "battery powered" smartphones using Android or iPhone which is foundationaly based on the Linux platform instead of windows phone OS? Wouldn't the customers DEMAND the manufacturers use the most efficient OS and give their business to whoever did?

What's your fan speed? If.it's above 65 your wasting energy and need a better cooling setup environment.

Also you should run 240 volts to further save on energy.

Also FYI,

70 Watts x 24 hours x 30.4 days= 51,072 watt hours (51 kwh)

51kwh x .145kwh = $7.39 per month.

As of this mornings whattomine mining earnings our fee is estimated to be ~$0.23 per 1070 ti per full mining month.

So this is a "Money Good" decision and we definitely earn our keep for you with the savings.

Here are some estimates for the other GPU's

1050ti: .09
1060: .14
1070: .22
1080: .24
1080ti: .33

To be clear on the 2 minute setup. I think the first time user was "testing" it on a single GPU pc before he put it on his rig. But he was amazed on how quick he got it mining. Here is his quote he DM'd me in discord:

I will comment!

TrollHodlrLast Tuesday at 11:30 AM
Dude.....
Setup on my 1050ti took like 2 min...
Most of the work was changing the mining algo line....
I will use it for BTCz, once price start picking up, but for now, at $0.33 kWh. I can better mine Zel and buy BTCz;
Oh, right, It's mining Zelcash for now..

Overdrive5Last Tuesday at 12:20 PM
So I think you can mine Zelcash with ewbf. Right? Wow 2 minutes! That's gotta be a new user record!

TrollHodlrLast Tuesday at 12:21 PM
no experience with linux since 25Y...
Yeah, it's mining Zelcash now

mine suqacoin with x22i algorithm. much less power consumption.

You have got quite a specification there. Though I am not expert in that section, I would love to know more about it. Love to know others opinion on this.

I don't know where you are getting this information from, but we have received multiple reports that ZhashOS which is a pendrive based Micro Linux where it's total size is less than 1 GB and loads completely into ram on boot is using 70-110 watts LESS than windows.

It is probably because CPU utilization is under 3-4% most of the time with this OS and it needs ZERO virtual memory so it is not hammering on a hard drive swap file. Actually, it doesn't even need a hard drive at all which saves a few bucks on the "Total Cost of Ownership" of your rigs.

Here is a tweet from firstminingrig showing power meter results: https://twitter.com/firstminingrig/status/1010449787802484736?s=19

So please don't consider all Linux's to be power inefficient. It can be VERY efficient when it is built to be. Which is what we focused on with ZhashOS. It is also why Linux is very popular in the commercial / Industrial embedded control market. And why Android and iPhone are foundational derivatives of it.

We are getting ready to provide release 3 (release candidate is out now) which will be a HUGE improvement in setup time and ease. We have received a #zhashos discord post that one first time user was mining in around 2 minutes after initial boot.

Here is the Bitcoin Talk discussion forum for other details and a screen shot of it in operation: https://bitcointalksearch.org/topic/m.40261859

ZhashOS is currently providing the asic resistant equihash miners such as EWBF, miniZ,gminer and bminer. Though bminer can also mine ethash.

I hope this clarifies the Linux power efficiency concerns.

First of all the Nvidia-emi is not completely accurate, it is an estimate. 755 W is the total consumptions not just the cards. And you have to take into account Linux uses 5% more energy when mining in comparison to windows os. with all that being said it is pretty normal all things considered.

For your configuration, energy consumption is very large! And a very small hash rate! Your 1070 should give a minimum of 31Mn - 4 * 31 = 124! The power consumption of your system should be ~ 110-115W per card! All this of course, given the correct settings.

As far as I know nvidia-smi provides just an estimate. There is some way where you can reduce the power draw. I think decreasing power to 110w might be helpful.

I don't have my 1070 ti any longer but this perfomance seems a bit low.
My 5 evga 1070 ti's sc were doing around 159 Mh with a power draw of somewhere in the 680 watt range if i remember correctly. Might have been the 600 watt range but didn't go higher than 700 watts. But yeah i really liked the performance of those cards you should be able to dial them in real nice.

Lets make simple calculations: 755W from outlet. PSU power efficiency is about 90%. So 755*0.9 ~ 680W. Your CPU TDP is 51W. With other hardware components it could give about 100W.
And finally your 564 + 100 = 664 / 0.9 gives about 750 W from outlet. Everything right.
