I deleted all below it is sidetracked from the thread.



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..

your statement that a 7 card  1080ti does  5400 sols + is wrong.  It will do 7 x 740 = 5180 sols  this is with  200 watts per card on a hybrid

If you get this card

https://www.evga.com/products/product.aspx?pn=11G-P4-6698-KR
you could do  7 x 760 = 5320 sols



I know this as I have a 8 card  1080ti
I have 2x 6 card 1080tis
I have had a 7 card 1080ti



My 8 card 1080ti simply can not be built anymore  as I can not get  the 1080tis
The board  for my 8 card  1080ti  needs to be an atx  and atx psus  go up to 1600 watts
This means I have to run my 8 card 1080ti  at 160 watts a card to not kill the psu.

So my 8 card 1080ti  pulls  1375 watts  against the psu and does 5200 sols.

I also have this 16 card unit for testing.

In a magical world I would own 8 card  1080tis  with  a 2000 watt corsair atx psu(no such thing as a 2000 watt)


As for this 16 card unit  with the small mother board that bridges to the 16 card pcie board
I would use a better card with better psus

They do have a better psu design  with 3x 1200 watt psus giving 3600 watts vs 2400 watt delta

If I massed produced this I would use a 1070 or 1070 ti  set to 110 watts  so 16 x 110 = 1760 add 140 = 1900 watts
you would do 7200 sols about 3.789 sols a watt
but that  does not exist.

This unit for what it is  is okay.  I could make it work at our solar array. Our next solar array would really be ideal for it

This is not a unit for a home with 13 cent power in the winter and 16 cent power in the summer





How do you get 760 from a ftw hybrid? I'm stable at 75% pl, +100 core, +150 mem. This gets me 725-730 sols, not 760?




I have no idea how you run your cards, or with what miners.I stand by my statement.
MY 1080tis (evga FTW3) all run 780+ sols each with DSTM, at 110% power and +70 core, +400 mem.
My 2 rigs have a 1600+1000 psu, and a pair of 1200w psus.
I pay $0.11/kw for power, so overclocking is far more cost effective.

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 build my rigs in 4u rack mount cases like this:
https://www.miningrigs.net/product/gray-matter-gpu-economy-case/
They can host in any datacenter once I exceed my power. Also have a new Octominer rack mount case on order. These are tighter, so require blower cards. With 8 1080ti, that’s 6ksol in 4u, hostable anywhere.
16 cards per rig is just needless complexity, and limits you to Linux. The majority of miners are better off with 6-8 high end cards vs 16 low end cards.


Pretty much exactly to my point earlier. A P102-100 is just a modifed 1080ti. its only effective of course if the price is significantly lower than current 1080tis (so well under $850/card).  Your EThash numbers look excellent, but everything else...meh. EQHash numbers seem really low. I expect a 1080ti to get well over 750sols/card and with the right tweaking 780+. That rig should be doing 12 ksol+
And why pay for 2x10gbe ports? total overkill.

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.

So in approximately 4 weeks we'll be running a batch sale for an initial batch of 120 x 16-GPU mining systems with these specs:

SKU: Ethereal Capital P102-100-X16
GPU: 16x NVIDIA P102-100 5GB GDDR5X RAM
Ethereum / Ethash Hash Rate: 800 MH/s @ 4100W (+/- 2.5%) (note estimate from manufacturer specs, TBC by actual benchmarking)
Zcash / Equihash Hash Rate: 11,000 Solutions/s @ 4500W (+/- 2.5%) (note estimate from manufacturer specs, TBC by actual benchmarking)
Monero / Cryptonote Hash Rate: 12,800 H/s @ 2400W  (+/- 2.5%) (note estimate from manufacturer specs, TBC by actual benchmarking)
CPU: Intel Pentium Processor D1508, Single socket FCBGA 1667, 2 Core, 4 Threads, 25W
RAM: 4GB DDR4 UDIMM (expandable to 128 GB DDR4 ECC RDIMM)
Storage: 16GB flash storage (expandable via 6 x SATA3 ports and 1 x M.2 PCI-E 3.0 x4)
Backplane: Supports up to 16x PCI-E GPU's at up to 300W TDP each
Network: 2x 10G Ethernet Ports
Remote Management: 1x Dedicated 1G Ethernet Port, IPMI 2.0 with virtual media over LAN and KVM-over-LAN support
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
OS: EthOS
Display Output: VGA
Dimensions (L x W x H): 750mm x 550mm x 200mm x 20kg (approximately)

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

Using hybrids isn’t smart, too expensive, radiators are a pain to place and you don’t need them.
My first rigs used evga FTW3 non hybrid. I have since switched to blower cards. Just picked up 4 MSI aero oc card for $779 each.

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.
