20821  Bitcoin / Mining support / Re: ASIC box construction - reflecting sound with ceramic bathroom tiles? on: March 12, 2018, 01:52:58 AM
When you're trying to mitigate sound from an ASIC you need a) to reflect sounds back into the box and b) absorb sounds within the box. I've contructed a box from 25 mm MDF and lined it with 30 mm closed-cell foam marketed for vehicle sound-deadening but I'd like to do a better job and I was wondering what else I could construct the box from that would improve performance. I've read that bathroom tiles are good at reflecting sounds because they're hard and very smooth (not the textured ones, obviously) so I was considering attaching them to the inside of the box between the MDF and the foam to improve sound absorption. Does anyone think this makes sense or is a waste of time?

I'd actually really like to make something from concrete like this but it would be really heavy (kind of why I think it would be effective).


no concrete  mdf is good but I have a series of  youtube videos

P102 eth performance from my factory source. $700 usd, but have to pre-order now and receive in early May.



Seems less efficient in terms of hash/watt compared to P104 which can do 37mh/s at 120w.

This is tempting, but I'm holding off expansion till end of GTC. Next gen just around the corner.
Damn that is really tempting! $700 is just a bit to high for my numbers at the moment.. $600 would have me chomping at the bit...


600 would be too good to be true.

700 does interest me.

I could order some at 700 but not 80 of them.

If we did a group buy  80 x 700 = 56000 usd.

any interest in doing a group buy?



@ Mfzbcoin
I won't be buying avalon since it won't have asicboost.

I get a dragon mint very soon. once I get it I will decide how many sha 256's to buy



Back to gpus

nvidia is going to sell  the p102-100 cheaper then the gaming gpus

thus pushing us miners to buy the mining gpus.

a 700 dollar  p102-100   vs a 900 dollar 1080ti

means buy the mining gpu.

This is going to cause an upheaval in the markets.

But I am only guessing.

Frankly  I see gpu mining taking a big hit due to  gear like the 16 gpu unit  I am mining.

My test unit has the

 p106-100

but the p104-100 and the p102-100   are coming


You can order  the 16 unit  with 16 p104-100   which are  1070 equals  set to 100% tdp it does  8000 sols at 2900 watts

but just clock  to 110  watts a card vs 150 watts a card  it will do 7000 sols  at about 2200 watts. it will have the 3 psu in a back plane setup.

at the moment they want 50 moq  at 11k  = 550,000 usd    this is out of my league.   I could order 2 or 3 maybe 4 of them.

I think  they are going to try to squeeze us out of the gpu mining game here.

11K for a 16 gpu rig ? bonkers ? I could build a 700+ mhs rx 580 rig today using 8GB cards priced at $450 a pop
for that price , I dont see how they will price us out with thier 3 month waranty POS mining only 4GB cards



those are 1070 cards i.e. 8gb not 4gb.  it is a false bios that can be unlocked to 8gb.

the problem I see  is really big farms  simply pushing diff high.
[/quote]

I get all that but with still they are paying alot for thier guy , I dont think they will ever fully undercut the small farmers
[/quote]

They are now testing the p102-100

Looks like it could have a very nice density.

I think one wire five shelf rack  can fit five and do over 50000 sols

@ 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
20826  Alternate cryptocurrencies / Mining (Altcoins) / Re: New 16 gpu industrial style miner review. Will post details soon__updated on: March 11, 2018, 11:59:27 AM
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

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.

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.

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.


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 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.

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.

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)

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
20829  Alternate cryptocurrencies / Mining (Altcoins) / Re: Questions about 550V Electricity Panel - 100$ Question on: March 11, 2018, 12:32:58 AM
1. How can you calculate how many rigs you can plug on that ?

- It's all about power consumption. You should ask about how many Current (Ampere) in your new warehouse power line. Then check back the power consumption for your rigs, so here you go. One of my friend has a mini farm with 360V power supply, and total current he could access is 60-A, so total power is 21.6 kW. All of his GPUs are P106-100, each rig has 12 GPUs which consumes about 1250W as mining ETH. So 21.6/1.25 ~ 17 rigs maximum.

2. How can I calculate what's the price of my Kw/H ?

- The letter from electricity company is quite a lot, I think you should ask them make a table which you could easily track. But as I understand, they make calculation based on several stages according to power consumption: 15,090 kWh and 50 kilowatts, I'm not quite sure but it seems expensive.


Thanks for the info, yes i'll contact them directly

My input is 600v and I have a Transformer 600V 45Kva to 240v if that can help

Well if the transformer works 45 x 80% = 36kwatts

So you could run 22 x 1500watt rigs. You would be at 33kwatt which is under  36kwatt derating I mentioned above

BTC B250C 12 GPU USB3.0-PCIE MOTHERBOARD



I have been talking to the guy about it, he informed me that it needs external power plugged in for more than 1 card to boot, also that 12 cards running that 6 pin power plug runs pretty warm. lastly the usb connections a very weak and loose, he has contacted the manufacture about the extremely loose usb connections.



So anti riser stance  seems to  wind over this board.


Shame as it looks nice.

Frankly  I see gpu mining taking a big hit due to  gear like the 16 gpu unit  I am mining.

My test unit has the

 p106-100

but the p104-100 and the p102-100   are coming


You can order  the 16 unit  with 16 p104-100   which are  1070 equals  set to 100% tdp it does  8000 sols at 2900 watts

but just clock  to 110  watts a card vs 150 watts a card  it will do 7000 sols  at about 2200 watts. it will have the 3 psu in a back plane setup.

at the moment they want 50 moq  at 11k  = 550,000 usd    this is out of my league.   I could order 2 or 3 maybe 4 of them.

I think  they are going to try to squeeze us out of the gpu mining game here.

11K for a 16 gpu rig ? bonkers ? I could build a 700+ mhs rx 580 rig today using 8GB cards priced at $450 a pop
for that price , I dont see how they will price us out with thier 3 month waranty POS mining only 4GB cards



those are 1070 cards i.e. 8gb not 4gb.  it is a false bios that can be unlocked to 8gb.

the problem I see  is really big farms  simply pushing diff high.

I’m rather new to mining, about 6 months in. And I’ve noticed running ewfb on smos, the dev shares seem to be happening more frequently. Is there a way to monitor the mining software as opposed to the pool? Thank you

Directly connect a video card from your rig to a monitor .


Then video tape the monitor

Short update here:-

1. DragonMint's have version-rolling AsicBoost support (reference).
2. Shipping will begin around March 15 - 22, but there's a lot to ship so please be patient.
3. Shipped version number will be T1, not 16T due to some mixup with Russian import documents that cannot be changed in time.
4. This picture is legit and the final version that will ship https://twitter.com/MyRig_com/status/971205544533835776
5. Phillip will get a demo machine once the shipping starts. But the reason for the secrecy was AsicBoost capability could be revealed before the patent holder opened the patent. This is unfortunate, we would have preferred more openness, but it is what it is, patents suck, but in this case, the patent can help protect the Bitcoin ecosystem. Now we're so close to shipping, we'll just give a demo machine to phillip once we ship.

More News coming once all necessary steps are taken!  Stay tuned and Happy Hashing!

Getting more and more request to list lower value than it was paid for, our answer to this is "NO" Commercial Invoice will have the price each customer actually paid for and no we CAN NOT list lower value to help you lower your import duty or fees.  I'm sorry for being so BLUNT on this but this is what it is.

DragonMint Bitcoin miners have AsicBoost inside!

Understand this is overt asicboost protected by the open defensive patent license meaning anyone can use it, and is not harmful to the network unlike covert. Ckpool and slush have support for this as it requires explicit poolside support, new stratum extensions, and cgminer needs to be modified to work with it.

nice product  now if I could find some cards for it.
20836  Alternate cryptocurrencies / Mining (Altcoins) / Re: GPU Mining with 30 1080Ti Cards (Need some advice) on: March 10, 2018, 03:06:05 AM
Sell all your gpus at premium and buy more coins iff we get another big drop. Btc below 6k


Sell 6 or 12 or even 18 of the gpus.  try to get +5-10%  ie sell a 700 dollar one for 735 to 770

between the mining you did and the sales price you get.  you profit more

keep some of the cards in case minng gets better


you have 6,12,18,24,30     as the possible gpus to sell

I would list six to start.


I want you to straddle  ie not sell all the cards  not keep all the cards.

well I have the 16 gpu version of the p106-100

it is a good piece of gear.

Improvements to a p104-100  and or a p102-100   would make it close to great gear.

but they would be hot and loud and truly meant for larger deployments

My first solar array could do 18kwatt fully free and size is a non issue power is capped at 18k it then becomes costly.

Still would love to  get a hold of the better  cards.

all this noobs  experts here recommending 6 cards rig dont know how to config a stable 12card rig under windows
im running several 12gpu rigs on windows 10 without problems


First of all, since you said Windows you obviously dont really know what you are saying. I say that a 6 card rig is better because i have managed literally THOUSANDS of GPU rigs. The way to make them stable is run 6 cards on linux. I can show you a fleet of mining rigs with 150 day + uptimes, which windows just cant match.

yeah my six seven eight card linux rigs run months on end.

but don't let the trollers make you angry
20840  Alternate cryptocurrencies / Mining (Altcoins) / Re: Single 12 GPU Rig Vs Two 6 GPU Rigs-Which would be better? on: March 09, 2018, 04:14:05 PM
for space efficiency, sure single GPUs RIG but for efficiency solve problems (if have a problem with those devices), choose 2xRIG, that's better.

How will you save space? There is a minimum distance between the GPU about 10-15 cm in order not to reduce the cooling efficiency. Length of rig 12, the GPU will be the same as the length of the 2x6 GPU rigs. The cost of the equipment will be approximately the same. I don't see any reason to increase the number of GPU on one rig.

some 12 card rigs 2x stack  they are taller then a six card rig.

there are other reasons for 12 card rigs .  smos charges 2 bucks per rig per month

so 10 x 12 card rigs  = 20 a month or 240 a year.

and 20 x 6 card rigs = 40 a month or 480 a year.

If you have tall racks   you can fit more with 12 card rigs.

personally  I like 8 card 7 card  6 card riser free  rigs.

Although  the new custom 16 card I am testing out is pretty nice.
