  I have been asked to review a 16 card custom miner.  I have done multiple reviews in the past.
This one will be more for a big deployment as it will use delta fans and be fairly loud.  I have not ironed out all details and will post more on this in the morning.

Edit

Some details  a few posts below.

Nice, amd or Nvidia?

Deleted

No worries  self modded.

I deleted him  and yours  since it dirties the thread

It has:
16x NVIDIA P106-100 6GB GPUs, delta sourced fans and power supplies, and a server class embedded motherboard.
 
Here is a link to one review. Plus a photo

Interesting design considering most high-gpu count prebuilts I've seen are usually enclosed in a case, and the PCIe switch they're using is full custom and seems to actually work! I'd personally be interested for the exact noise level of the device in decibels and possibly temps. Looks nice and neat on the link you posted to another review, keep us updated!

It uses one of the best  server psu's on the market.  The  delta 2400watt that parallel miner was selling.

For that alone I like it.  It has  1 small low end gpu I think a nvidia 730(not sure)  so you can have a screen to view.

Plus the 16 mining gpus.  Does around  4800 to 5100 sols of zec.

This is the cpu. https://ark.intel.com/products/91558/Intel-Pentium-Processor-D1508-3M-Cache-2_20-GHz

It can use ECC ram. It has a  TDP of 25 watts.

It has ethos on a usb stick to run the gear.

This is for a medium or large scale setup.  Buysolar and I are  trying to develop a second solar array in NJ  this would be an ideal unit for us.

Our second array  will be 2 acres  and generate  30-40 kwatts 24/7/365  via tie in to the grid (NJ has good rules for this)

We can operate it remotely which  will be nice since it is about 50-60 miles from Howell, NJ  where the 2 of us live.
I hope to get this gear in under 1 month.
I will run it in my garage meter power use and sound.  Do a few  videos for my you tube channel.   I will then move it to the solar array do another video.  Get a feel for power use per sol etc.

This looks good. Do you have details on price?

The display GPU is provided directly by the onboard ASPEED Baseboard Management Controller (BMC) from the Supermicro X10SDV-2C-TLN2F motherboard.

We have recently completed development of the 'Power Backplane' which will allow up to 5 x 1200/1500W Common Slot PSU's to be combined into a single power feed.  This is to support up to 16 x P102-100's, or higher wattage GPU's (300W TDP each) once they become available.

https://pbs.twimg.com/media/DUhWjYVU8AEbHoY.jpg:large

   Thank you for your clarification on graphics gpu.
The Power back plane is a good option. Will you use it to create redundancy for the psus? Or just to allow for upwards of 5000 watts per unit?
My solar array with buysolar is not small and I hope to have it expanded  from a 1 ⅓ acre array  to 2 arrays of 1 ⅓ plus 2 acres.
If buysolar and I  do this the  dense option  of 1070's or 1080ti's  would be best for us.

I would hope nvidia continues to shift miners into specialty  cards such as the ones in your build.
This would help keep both the gamers and miners happy. I could see your build with the backplane loaded with a new mining card as it is rumored nvidia is trying to build a card line for miners beyond the one in the review above.

   I would love to  have a unit  with 4-6 psu's on the backplane running 16x  1080ti varients  using about 3200-4000 watts.  Each unit could have its own 20 amp 240volt circuit.  No need for pdus since the software allows  access to the unit world wide.


Oh to all kjs is the person involved with supplying  the demo to me.

 As we continue to iron this out via pm and emails I will hopefully get more details on this item.

If you use so noisy fans (above 53dBA) why did you select 25mm thickness fans? Delta fan models like ffb1212VHE or even ffb1212SHE with 38mm thicknes has 1.5 times better airflow and air pressure than you use. Also about 70C degree GPU temperatures at datacenter conditions is not good especially for 1060 GPUs. What will be with 1080 or 1080ti GPUs that have 2 times higher power consumtion and correspondingly heat production?

The review is not mine  and  the reviewer states  temps are  under 70 c  not  at 70 c


He used Delta FFB1212SH 120x25mm Super High Speed Fan   and each one  uses 5-6 watts less then the
ffb1212she

ffb1212she
https://www.digikey.com/product-detail/en/delta-electronics/FFB1212SHE-F00/603-1081-ND/1014412


since the gear has a lot of fans  you save some power over the one you mentioned.

now the ffb1212vhe  uses same power   and moves  170 cfm  that may be an improvement of course the gear will be 1 inch  deeper using that one.

 He may  do that when the more power gpus are available to him.

I will find the 70c reference in the stock review.

"From another angle, you can see the twelve Delta brushless fans that keep the 16x NVIDIA P106-100 GPUs cool. These are the class of fans we commonly see in servers instead of consumer focused fans, and they move a lot of air. Our GPUs were kept sub 70C without issue."

"The system performed extremely well during a few weeks of testing. We did not see any issues during our testing in a 72F / 22.2C data center."


See the two references. Temps may be an issue in an 85f room.  But don't fear when I run real world tests  they will be more rugged.  My garage will be 85-90f.  The solar array will be 90-95f   we will see how cool gear stays.

I also plan  to add panels  to direct air flow left and right sides and top and bottom.

Yes, you gain redundancy from the power backplane as well.  In addition we have the ability to be able to power cycle the entire GPU backplane and GPU's from the backplane which enables you to recover from some faults that can only be rectified by power cycling.

Those fans were determined to be ideal for the application.

In v2 of our GPU backplane we have PWM fan support and will be using this in conjunction with 6 larger fans to run the fans at exactly the speed required to maintain the target GPU temperatures.

kjs  Has emailed me with shipping info.

I should get this on Tues the 6th of March

I am looking forward to testing it out.

Spam deleted

hey i'm glad this review is happening.

I have experience with a few of these units and they are formidable.

cant wait to see the new review.

Yeah I want to see how they run in less then ideal spots.

My garage will be hot.
It. Should  be good test.

That's a great looking rig... I really like the modular design and that PSU is awesome.

Looking forward to hearing about your experience.

Fedex sent me a notice it ships on friday the 2nd of march.

I am stoked to review it.

It shipped this morning weighs 55 pounds West to East coast comes tues


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

Let's hope FedEx don't destroy it in transit.. they have a habbit of doing that to my shipments.

well like everone in  here the design looks great and doesn't take alot of space but i have some question regarding the mining rig, can this rig mine bitcoin and if it can, can it be better than asics or better just buy asics

I guess I take it at face value. As a legit question.

It mines alt coins such as zcash  you can hold the coins as zcash  or trade to btc.

here is a smaller miner  with less gpus
It is setup to mine at nicehash  which  auto converts to btc.  this smaller miner is earning 0.0010 to  0.0012 btc a day after auto vert is done

https://i.imgur.com/jzL3Inv.png

Any estimates on price and public availability?

shoot a pm to kjs  he is the man  that provided me the demo.


this is his profile

https://bitcointalk.org/index.php?action=profile;u=336359

Please  I deleted your post. I have not tested it since  It arrives in 3 days.

The frame should use the same aluminum that my waterblock Spotswood uses .

ugh, and people wonder why the forums eliteist attitude pushes people away.
w.e, thats what i get trying to engage with you, take care then,i wont be ordering one, sour taste now from this

Great job done. Gonna dig into it  ::)

Nice rig, pretty much commercial use almost I think this would be too loud for most garages even

I simply  said you were in error.


  I can not allow an error to stand without a correction.
I quoted your error for all to see it. Here is why:  This is expensive gear  I don't want anyone to think 1080tis  have been tested in it since I don't have the gear as of now. When I get the gear I will try to test some of my 1080ti's in it.



  Look we all make errors we are humans plain and simple.
I do not want you to be offended  I am a regular guy not an elitist type at all.
You may have thought  I wrote I tested 1080tis in this gear so to be clear I have not done that at all.

Do you recommend nicehash to monitor gpus + system stats if you have more than 2rigs?

Nice rig build btw! ::)

I use nicehash  because I have multiple  btc addresses.

yeah and I am going nuts getting it to mine.  Cant seem to get an internet connection.

smaller then I thought  fits a 3 foot rack nicely.


which ethernet cable jack did you plug into

https://www.servethehome.com/wp-content/uploads/2018/02/Ethereal-Capital-P106-100-X16-Motherboard-USB-and-PCIe.jpg

I suspect the Ethernet port above the USB thumb drive is the IPMI port.  That's for management.  Try one of the other 2 ports next to the VGA connector.

I tried all 3 and I can't get a signal.

Some times  this would happen with some with rasp pi 's

I am going to disconnect a few other   pc's and see if it is a port conflict

Update  one of the mac minis was going to 192.168.0.106  and the miner was going to 192.168.0.106

turned off a mac mini and then got the miner to go online  yeah baby!!

BTW  you were correct  in that the double stack is the one to plug into.

Going to point to nicehash and do zec if possible.

Okay trying to program a conf in at the moment.

I got it working yes!!


About 4675 sols. Temps range from 65c to 76c

And I managed to make sound okay

What is okay sound?

S-9's = really bad.
Pandaminer = bad
Avalon 741 = loud


New 16 gpu = better then the 3 above
With my sound mod I would say  garage mining could work.

But these are still heavy duty pieces of gear they weigh 45 pounds are 31 inches by 17 inches by 11 inches

I will meter for sound and power use on Weds.  I did a few videos nothing posted I am a bit tired.

https://www.nicehash.com/miner/3QPFEdX8rtXHoVZHct5eUbp7AK1t1vRMfL



11b596   Equihash   4781.32 Sol/s


feel free to look at it mine at the link above.

 

I need to figure why these  port conflicts happen on my  system.  I killed hours  trying to figure out what was wrong today.


My power guess will be 16 x 112 = 1800 + 50 = 1850/.94 = 1968 watts

When I was running 8x 1080tis  on low clocks  with my onda b250 build I did 5200 sols at 1300 watts or 4 sols a watt at the wall

this gear will be about 4675 sols at 1968 watts = 2.37 sols per watt 

 I will tweak it  to see what I can boost that to  On the autominer.at

I got  3100 sols at  1025 watts with zotac 1060s or 3.02 sols a watt.

I think I can do that with this gear.  I just need to understand  the power settings for  ethos.  I am pretty much a rookie at ethos software.

Yes, the cable above the USB ports is the IPMI port.

The Ethernet port you want is the one towards the bottom of the motherboard.  Ensure to connect to a 1 or 10 Gigabit Ethernet switch as 10/100 Megabit Ethernet is not supported.

The power settings for each GPU are set within the local.conf file at /home/ethos/local.conf

You need settings like these for NVIDIA GPU's:

pwr <rig ID> <GPU 1 W> <GPU 2 W> .. <GPU 16 W>

Example from one of my real configs for Ethereum mining:


Also recommend reviewing the contents of the EthOS Knowledge Base and Sample Configuration Files:
http://ethosdistro.com/kb/ (http://ethosdistro.com/kb/)
http://ethosdistro.com/pool.txt (http://ethosdistro.com/pool.txt)

Okay I got it to run  with less power.

I used global clocks

75 watts
+60 core
+450 memory

this gives me  4600 sols

also it slowed fans to 3.5-3.6   which I am thinking means  3500 rpm

I will take some photos today

https://i.imgur.com/E47vupI.jpg

Phil  that is the material you got from homedepot ?  you built some other sound proofed items with it.  A big roll was dropped shipped to you correct?

@ yankees yes I will post links later.  Also used a piece of thin plywood.

here are some gui readouts

temps are all good with the downclock to 75%

I clocked low on purpose  to keep sound down

4278  sols  doing about 1200 watts-  I will meter this

cpu usage of 28.9%
cpu temps 48c
ram used 2.9g of 3.8g  about .877g free

https://i.imgur.com/x5QynvN.jpg

Wow.

What I like about it:

1) the size it fits on a 3 foot shelf
2) you can tame the sound via underclock
3) the 16 slot board which allows  16 gpus to run off the small server

Now that it is working I will do more videos  with sound meter and power readings.

i ran in to some issues running these on older switches as well.. ensuring the conventional ports (not just maintenance) were gigabit capable ensured proper compatability and connectivity.

these can be stacked too..

they are fun to hoist onto ladders and store on the top rack of your stack :)

the open frame is great for cooling.

your garage has come a long way from your 4gpu rigs eh phil?


 

I have all 1000 speed switches.  but this problem does show up once in a while.

I have modem- router - 24 port switch -switch - router - switch - router

  Most mining runs on the 24 port switch the router is address 192.168.0.1

the second router  is address 192.168.1.1   
the third router is address 192.168.10.1

I moved  the mac mini from the 24 port switch to the second router problem ended.
                             

I estimate  that the garage has had more then 250,000 usd in gear pass through it.

Back in 2012 when I started I had:
 12-14  2gpu rigs  all sold to gamers after 2-5 months . Max power pull was about 9kwatts.   =  20k
It had more then 1000 usb stick run in it.  -------------------------------------------------------  =  50k
Maybe 35 s-1's  ------------------------------------------------------------------------------------- =   20k

3  rockerbox ------------------------------------------------------------------------------------------ = 500
a few s-5's -------------------------------------------------------------------------------------------- = 2k
some avalon 4.1's ------------------------------------------------------------------------------------ = 2k

So the STH review labels this as a mining rig ideal for remote data center deployment.

But how do you deploy something like this that isn’t even remotely rack mountable? Is the data center supposed to just leave a couple of these in the corner with some extension cords running to them?

looks slick as hell, i want one

Seeing as OP hasn't posted detailed specs, I contacted the seller and got the below specs on their P104 rigs:

SKU   Ethereal Capital GPU Mining System P104-100-X16
GPU   16x NVIDIA P104-100 4G GPU

Zcash Mining Speed (Equihash)   8000 Solutions/s @ 2900W (+/- 2.5%)
Price   11500 USD excluding freight, import duties and taxes
Minimum Order QTY   50 units

I would be interested in seeing these specs for their P106 rigs, but didn't inquire as the MOQ is a bit too high for me.

For the price, it's not a terrible deal.  With current prices, ROI is about a year, but it's also worth noting the extra peripherals.

your specs are for the newer model.

8000 sols using 2900 watts
---------------------------------------------------------------------------------------------------------


The one I have has the p106-100

4400 sols using 1500 watts

mine uses the single  delta 2400 watt unit psu.
--------------------------------------------------------------------------------------------------------
The newer model  was to have a metal shell around the  aluminum frame.

Have you seen/had any experience with the newer model?

these look awesome, will consider getting a few for our shop

Info Pls

I got the 24 foot size

Mining data centres typically use shelving rather than traditional 19" racks, so that is how you do it.

To: philipma1957

Thank you very much!

These fit on a three foot shelf.

They are about 31 inches .

They can be clocked to use 1350 to 1800 watts.

So at pushed clocks in a cheap power setup.

2 x 1800 = 3600 watts

A 20 amp 240 volt circuit is 4800 watts derates to 3840 watts.

This means 2 rigs per ciruit.

A 30 amp 240 volt circuit is 7200 watts derates to 5760 watts

Which is 4 of these clocked at 1400 watts

It is nice to see that the flexible power usage is available with them.

They would be dense which is a good feature.

I really think that these would be nice if buysolar and I get our second solar array going.

A simple 10 by 10 shed would allow three three foot wide racks each with 5 shelves.  That would be 15 units.

Pulling 21000 to 27000 watts.

We could do two sheds and that would be all the array needs

I just don’t get the lots of small cards approach. A 7 gpu 1080ti rig will outperform this on most algorithms, at significantly lower cost.
7x1080ti gets you 5400+ sols, 266phi, 140 x16r, and 14k neoscrypt.
Pretty sure 16x 1060 equivalent cards can’t touch that..

Would love to see that thing do it's stuff on https://forgetop.com/

I would consider ruuning there after I do the 1 week at nicehash mining zec

We are currently in the process of designing our sheet metal chassis and then integrating our multiple power supply solution into it.

Our GPU supplier has recently made the P102-100 GPU available to us so this is what we will be offering going forwards as the cost benefit of P102 vs P104 is favourable.

Power Supply: Either 4 x 1400W or 5 x 1200W Delta Power Supplies in N+1 redundant configuration (TBC)
Cooling: 6x 4500 RPM 120x120x38mm Delta fans with PWM speed control

Dimensions (L x W x H): 750mm x 550mm x 200mm x 20kg (approximately)

Yeah this would a real beast.

Bigger fans should work.  But it will be louder and hotter then the 106-100

The specs they list are really pushing the cards 4500/16  = 250 watts plus per card.

My gut tells me set a tdp of 200 watts and you will do 3200 plus 300 = 3500 watts and still be over 9000 sols

Benchmarking is the key, I am awaiting delivery of 16 x P102-100 GPU's so I can actually test them.  They should arrive within a few weeks.

WRT the fans we will test the existing 12 x 120x120x25mm 3400 RPM fans with PWM speed control vs 6 x 120x120x38mm 4500 RPM fans with PWM speed control to determine the relative thermal, acoustic and power characteristics of each config.  The best combo shall prevail.

Your problem is you are crippling your cards running them at 75% power on Equihash. Underpowering cards is fine for mem intensive algorithms like cryptonight or eth, but it directly reduces core clock speed. With an FTW3 hybrid card, 120+ power and +80 core, +400 mem should get you over 780 easily. Use DSTM or Excavator for best results.

I deleted all below it is sidetracked from the thread.

Running cards at 110%  is a method  I don't do.
But  if you build a 7 card rig and run at 110%  you will  get your higher numbers.

Your first criticism was based on the cards being only  1060 equals.

your next criticism is based on the newer bigger cards not hashing high enough as compared to your hybrid cards  which are now over 900 usd not 850

https://www.evga.com/products/product.aspx?pn=11G-P4-6598-KR  they are now 909 plus shipping


I would rather have a pair of six card  evga hybrids rigs  set to  200 watts  each rig would be about 6 x 750 = 4500 sols 2 rigs would be 9000 sols

they would pull  around 1300 watts each. Or 2600 watts total.

 The problem is  I can not get those cards.   and even if I do get them 12 cards are 10908 usd plus shipping

I am also a mid sized miner.  Not a large scale guy.  The rigs in this are more for a big scale op.  easy to deploy and not a lot of tweaking.

Are you better off with your setup then buying this  it sounds like you are.

Is a guy looking to buy 50 of these and dropping them into a warehouse  better off with this setup then your setup  I think so.


For me I may get a few of the larger rigs for the solar array.  I won't be running it in my garage  as it will be too hot and loud compared to this model I am testing for them.

The  p106-100  can run in your garage  and you can have  them set to do 80 watts a card.
In a properly setup  warehouse/data center you can set them to do 100-110 watts a card.  


I really like the form factor for these cards  spotswood's frames are nice.  I would love to see the final design of the p102-100 models.  wrapped in sheet metal around the aluminum.  

30-31 inches wide  16 inches deep  11 inches high.  using the rack below will do 5 rigs or 80 cards at 200 watts each and 700 sols each is 56000 sols  and maybe 19000 watts

So you have a spotswood for hybrid's   and you put 7 hybrids  and 1 zotac mini.  The build is on youtube  that  frame is the same size as this frame.

If I recall  you used a corsair psu with  1500 watt  and you pull 1375 watts at the wall doing 5200 or 5300 sols.

Forgetting that  you were taxing the psu  if you had five of them  on this rack  you would do 26000 to 26500 sols and 6875 watts.
It would be efficient since you set the cards to 150 watts so as not to kill off the psu.

But density wise it would be less then 1/2 the hashpower

@ yankees

with the current atx psu's  those spotswood builds  are best with  only six cards  set to 200 watts  the rig pulls 1275 watts  against the 1500 watt corsair psu.  It does 4300 sols.

So the rack would have 5 rigs  with 30 hybrids or

5 x 4300 = 21500 sols

5 x 1275 watts = 6375 watts.


And the newer 16 gpu with  p102-100

on the same rack may do

5 x 11200 = 56000 sols
5 x   3800 =  19000 watts

This would be great density.
Hot and loud but  a ton of fire power.

At the moment all in blue is not tested .  But does show the potential of large hashpower in a small spot.

The solar array buysolar and I use  could run  that rack  for 'free'  that is it's power cap  for this time of the year.

I do like these  for future  solar arrays.  if we do an array  that does  40000 watts  24/7/365  we only need this shed
that would allow 2 racks  10 units  112,000 sols 38000 watts

Looks like phil is spot on  the good gaming cards  are being priced  too high now.

I have 2 of these  and they are about just as good as the  evga hybrid's  I paid 803  each shipped to my house.


https://www.corsair.com/us/en/Categories/Products/Graphiccards/Hydro-GFX-GTX-1080-Ti-Liquid-Cooled-Graphics-Card/p/CB-9060011-WW


They are now 999.99  plus shipping and sold out.

I also have 2 of these


https://www.evga.com/products/product.aspx?pn=11G-P4-6698-KR

I paid 849  each plus  26 to ship

They are now 939 plus shipping

Or buy a bundle  for 1169

https://www.evga.com/products/featured-bundles.aspx  plus shipping and get a mobo you dont need.


The p102-100 starts to look better at 700  a piece  which means a 16 gpu unit from kjs  may be good.

Im just wondering what is the price of P102-100

I have seen the p102-100  available in bulk buys for 700 a card.

https://bitcointalk.org/index.php?topic=2674194.msg32071657#msg32071657


So this model  would have 16 x 700 = 11,200 for the cards alone.
add in 4 psu's
a frame/case 
a stick of ram
the mobo with built in cpu
the bridge to the 16 slot pcie board
the 16 slot pcie board
the ethos os
the usb stick
many fans
labor
profit for the seller

and we are talking $$$


but  if I use  the evga hybrids  they are more then 900 a card actually more then 1000
and the corsair are 999 plus shipping

so that is 14 x 1000 = 14000   14 hybrids or corsair
and 2 x 850             =   1700   2 zotac 1080ti minis
 
2 mobos    =     350 if I use  onda b250
2 psus       =     900 if I use corsair ax1500i
2 frames    =     230 if I use spotswood
2x the ram =     160 if I use 8gb crucial
2x cpus      =     400 if I use i5 7400
2x usb sticks =     20 if i use samsung 32gb

cost is 17760  for 2 x 8 card rigs  that I can not max  since the corsair psu is a bit too weak  so I do 10000 sols at 2600-2800 watts 

pros quiet setup
cons I push the corsair ax1500i very hard
cons I can't get those waterblock cards


or I get the p102-100 16 card rig

it does  11,200 sols
it is loud
it uses  3500 watts
I think  the build  costs less then  17,760 (I guess this I don't know)

I am tired of deleting these and arguing with you.

You are pulling the thread off topic.

It is nice you found 4 msi aero cards  at $779   but 4 cards simply  are not the same as 16.

A 16 card rig with p102-100  is for a large mine.


Note my title  industrial style miner  not mid sized miner.

start mining those masternode neoscrypt coin's then setup node with coins  ;D

That is certainly something that can be done with a bunch of these in a large farm.

I have been telling people to mine their own node and avoid pools for years.. particularly with ethereums frequent block rewards.

instead of getting less than expected rewards due to pool fees and stale shares, I have always experienced better than expected yields.

but I would never do it with longer than a 2 week expected block reward timeframe, which for eth is currently like 75 rx570's with bios mods.

back in the day though it was pretty fun including messages using special solidity messages into the blockchain with my blocks.

and with uncle rewards it was even more aluring.

About right, we will be offering the entire system for 16k USD.

We are going to run a batch sale for 120 units in the next few weeks for shipment in May.

16k could be viable.

a low power area should be able to turn a profit with them.

Well some preliminary results for the P102-100-X16 system are here:

ETH - Total Speed: 820.610 Mh/s, Total Shares: 21(3+2+2+2+2+3+0+0+0+1+1+1+1+1+1+1), Rejected: 0(0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0), Time: 00:02
ETH: GPU0 51.312 Mh/s, GPU1 51.389 Mh/s, GPU2 51.392 Mh/s, GPU3 51.328 Mh/s, GPU4 51.196 Mh/s, GPU5 51.074 Mh/s, GPU6 51.250 Mh/s, GPU7 51.422 Mh/s, GPU8 51.220 Mh/s, GPU9 51.242 Mh/s, GPU10 51.083 Mh/s, GPU11 51.413 Mh/s, GPU12 51.224 Mh/s, GPU13 51.376 Mh/s, GPU14 51.252 Mh/s, GPU15 51.437 Mh/s

:)

those are good numbers.

whats the watts?

The  P106-100 I have been testing was  next to flawless  running zec.  It never crashed  and gpus stayed under  70c at all times in a 85f-97f room.

The current state of gpu mining  is a bit low for profit.  But A low power setup and these are still okay.

I see there still arent fan grills on the intake side of this unit.

it is good to see casper wont be stifiling gpu profitability before 3gb cards are off the table when it comes to ethereum.

I do still I think 2019 will e a restructuring year when it comes to mining industrially as well as in the hobby realm.
