Looks good, but any thoughts about its bitcoin hash rate?

Bitcoin.

On a GPU.

*ROFLMAOSC for about 5 minutes*

You have GOT to be joking, right?

Bitcoin Gold  Cool 675 sols/sec.

Finally we get those information, I also guessed its hashrate should be about 50 mh/s. Btw, have you tested it with other algo, for example mining Monero? One month ago 775$ per card is a good deal, but now it's hard to say as Bitmain's going to release asics miner E3. Even me, I'm going to switch all of my Rx580 rigs to mine Monero in next month. Claymore already added new string for Monero hard fork. Hopefully Ethereum will have some move on it.

Keep in mind that these GPU's only have 3200 CUDA cores versus a 1080 Ti which has 3584 CUDA cores.  The P102-100 has optimised memory timings and is hence faster for memory bound algorithms (such as Ethash used for Ethereum mining), but slower for compute bound algorithms (such as CryptoNote for Monero and Equihash for Zcash mining).

Zcash benchmarking with DSTM shows around 675 sols/second at stock clock speeds.  I achieved a maximum of 710 sols/second with a +100 mhz core overclock.

What price are you getting them at, the p104ís were  overpriced and not worth it, so Iím wondering if these are in the same boat especially considering the e3 release this summer or sooner.

Less than 800 - if anyone wants a few we can sell batches at 775 USD each.

New version is out - 1.31 from April 4th

Someone checked if voltage can go below 0.9v with this one? I see they improved their voltage control tool.

Yes, you can set voltage to less than 950 mV by setting
Code:
safevolt disabled
within your config file.

29  Alternate cryptocurrencies / Mining (Altcoins) / Re: New 16 gpu industrial style miner review. Will post details soon__updated on: March 19, 2018, 12:54:14 AM
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)


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.

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

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.

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

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.

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 isnít 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?

Mining data centres typically use shelving rather than traditional 19" racks, so that is how you do it.
34  Alternate cryptocurrencies / Mining (Altcoins) / Re: New 16 gpu industrial style miner review. Will post details soon__updated on: March 07, 2018, 05:51:20 AM
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.


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:

Code:
loc c94380 USems001
miner c94380 ethminer
mem c94380 4600 4600 4600 4600 4600 4600 4600 4600 4600 4600 4600 4600 4600 4600 4600 4600
pwr c94380 80 80 80 80 80 80 80 80 80 80 80 80 80 80 80 80
cor c94380 -200 -200 -200 -200 -200 -200 -200 -200 -200 -200 -200 -200 -200 -200 -200 -200

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.

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.

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?

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.
