I cannot wait to get my hands on this Asrock H110-Pro BTC (1 x 16X slot and 11 x 1X slots !)

Same.... I just hope people don't start gouging the prices on them like they did with the H97 boards.... they used to be ~$100 or less; now they cost an arm and a leg comparatively.

I can only imagine people taking a ~$150-200 board and gouging the price into the $450 range......

I wonder what kind of OS/drivers could be able to handle so much GPUs !

[vg54dett]

@ Citronick

I remember you used pci-e 1 to 3 splitters on some boards for your previous rigs.

I'm using some on MB with not enough PCIe slot (I bought these mobos when their price + splitter price is better than mobos with 6 to 7 PCIe slots).

Generally it works great, but I have an issue with one setup. Each time I add more than 1 GPUs in a mobo slot (thanks to the splitter) , I end with one of these GPUs hanging after few minutes. (Claymore Eth mining + SMos)

I have similar rigs without any problem, the only difference here is I use RX570 Pulse (first time) instead of RX470s.

Do you have an idea of the reason for that problem ?

I'm about to install a W10 to check if this is a SMos/RX570/splitters compatibility issue.
Maybe SMos cannot handle more than 6 RX570s without hanging ?

my first suspect is power - so maybe a bigger PSU.

So far I got it working with R9-Nanos (7xGPUs) and R7-370 (7xGPUs) -- I have dismantled the R7 rig and now permanently with R9-Nanos mining ZEC.
Its my most powerful AMD ZEC miner at 2800 sols.

I have moved away from using these splitters because its too sensitive and currently using MSI Gaming M5 (Z170) and MSI Z270-A PRO (using M2 adapter) for 7xGPU rigs.

I cannot wait to get my hands on this Asrock H110-Pro BTC (1 x 16X slot and 11 x 1X slots !)

https://bitcointalk.org/index.php?topic=1924942.msg19271012#msg19271012

It's not power related issue as I'm using server PSU with many room left.

In case it could help someone, I managed to get things working by cheating : I put 3 RX570 in a rig + 3x470 , and the 3 others 570 in another rig with the other 3 470.
One hour working so far.

I wonder what kind of OS/drivers could be able to handle so much GPUs !

Last year there is this dude that posted on Claymore ETH thread with his 16 x GPU rig using a multi PCI motherboard - something like deep learning and NVIDIA Tesla systems would use. I believe he was using Linux OS.

Claymore had to do version for more than 12 x GPU... It was quite an awesome project but the motherboard was 2000 bucks  

I hope the H110 mobo would be under 150$

seems to be more for a 60 gpu and up setup.

I could see have 1 and it breaks and all my 1080 tis don't work.

 now if you were running 5 or more  of them and had a spare no worries.

Hey everyone... wanted to get your feedback on best known methods of withdrawing USD from Crypto-Exchanges.

What I have been doing is moving ETH from Bittrex (where my mining operation sends the rewards) to my Coinbase ETH wallet, then selling a few here and there directly to my Coinbase USD wallet.  I haven't actually withdrawn that USD yet but it seems pretty easy to do.

However, I am now considering selling some of my DCR (cashing out to USD) and trying to figure out the best way to do it.  Of course, i could sell it on Bittrex, then transfer the resulting BTC Coinbase, then transfer that amount of BTC to my Coinbase USD wallet but that seems like a lot of steps.  So, I was trying to figure out if it is possible to get USD directly from Bittrex, but can't quite get there.  They do have a wallet called Tether that seems to be linked to USD, so I assume that I could sell DCR to BTC, then buy Tether with BTC, but then can I actually get Bittrex to send me real USD (via check, eft, etc) or is that Tether wallet just meant as a temporary holding place to wait out a down market or something?  Couldnt seem to find the info on Bittrex about if its possible to actually cash out USD so any tips would be appreciated.

once it is in coinbase the irs will know you have it.  i.e. reportable on a tax return.  My thoughts are use it and go legit pay tax etc.

I can offer some advice  lets say you have 3 btc on coinbase   lets say most of the btc was transferred when btc was   2600

and you hold and coins drop to  2000 .  So the 7800 dropped to 6000   which number do you think is the one the irs picks for you to use for taxes  yep  the 7800  .. So  to pull from an exchange like bittrex and put into coinbase means you need to consider  this.
Before the runup came from april I had 8 coins in coinbase  I now have under .03 coins there.

 as cashing them  would protect me from a tax bill that I could not pay.

I will do my level best to avoid sending any coin to coin base other then a purchase from my bank account.  until 2018

yes, i certainly understand the potential tax implications for cashing out via Coinbase... although i recently read that the challenge CB is putting up in court may have a reasonable chance of succeeding.  Also, the basis issue is an interesting one... typically, like with stocks, your cost basis is easily trackable so that's what I pull and use to prepare my taxes and should the IRS ever feel they need check my measly profit, then can easily do so based on the UBS data, etc.  However, with crypto, it's not that easy. Sure, I have an app on my phone where i track both all of my mining rewards as well as other crypto activities like buying BTC outride for usd and trades, etc.  Maybe the IRS could somehow dig into mining pool's data to actually try to validate what a miner's true basis is but man, what a huge waste of effort (nothing new for the government i know)... BUT... when you start to talk about trading one crypto for another and how that affects your basis, it is something that probably not many people can even comprehend... myself included.

But aside from that, back to my original question...

Republicans in congress are starting to get involved in the case to put the irs in line.

https://www.cryptocoinsnews.com/republicans-slap-irs-coinbase-bitcoin-tax-hunt/

As far as taxes go I would just do your best to report your earning and gains.  It is basically impossible to report absolutely everything and figure out a cost basis to be 100% correct as the irs wants.  Nothing actually gets reported at this point so the summons is just so they can sniff out the big fish dodging taxes anyway..

The previous poster is incorrect about the value being assign when you transfer coins.  The only that that actually matters is the date you acquired them and the date you sold them, what happens to the price before that point does not matter.

So far I got it working with R9-Nanos (7xGPUs) and R7-370 (7xGPUs) -- I have dismantled the R7 rig and now permanently with R9-Nanos mining ZEC.
Its my most powerful AMD ZEC miner at 2800 sols.

@Citronick (and whoever can offer some advice)

Sorry to piggy back on this.
I have the opportunity to buy Pro Duo cards for about $580 a piece brand new, which I understand is a pretty attractive price.
Since basically they are two Nanos in a single package, do you think building a ZEC rig with Pro Duos is a viable option at this price?
Also, the Pro Duo has 3 x 8pin power ports. Would you plug each port separately directly from the PSU?
Or would it be ok to share a single PCI-E cable among two ports and use another cable shared among the remaining port and the riser (total two PCI-E cables)?
Thanks in advance.

Pro Duo are with HBM memory same like Nanos -- ZEC likes those fast HBM memory and lots of compute cycles.

Unfortunately.... Fury cards needs alot of power (exception of Nano which is 150 tdp or with modded rom even less power).

Using normal PSU ie. EVGA-1300-G2, there are 6 x VGA connectors on those.... so if you card needs 3 x 8pins then you can do only 2 cards with this PSU.

If you use EVGA-1600-G2, the are 9 x VGA connectors on those... so you can install only 3 Pro Duos.

For risers, you get power from SATA power cables from the PSU.

If you use a server PSU/pico/breakout board solution, you can have up to 10 x 6pin connectors per PSU.

Assuming you need at least 300w per card, you can get a dual server PSU of 1200w each = 2400watts total for 3 x cards per PSU.

So with this dual server PSU solution, you can get 6 x Pro Duos. But you probably need to custom make your cables to have at least one cable for each card to have an extended PCIE or SATA connector to power your risers.

Alternatively, you can use NVIDIA cards for ZEC.

A 1080ti can outhash your Pro Duos... 700sols per card easy.

A 1070 can do 400ish sols, which is comparable with a Nano or Fury.

The 1080ti uses 2 x8pins and 1070 uses 1x8pins.

So there you have it..... NVIDIA maybe better in ZEC mining after all.

The cheapest 1080ti I can buy is the ZOTAC FE, and it costs $750, so for me it offers 0.93H/$.

The Pro Duo costs $580 and can do 900+sols, i.e. 1.55H/$.

For the setup, thinking more about it, I would probably use 2 x Pro Duos per rig, plugged directly to a cheap mATX mobo with 2 x PCI-E 16x slots, like BIOSTAR H170GT3 or Asrock B85M Pro4 (both cost $67 here), so no risers required.

For power, I'm guessing a 850W PSU should be enough for that setup, but it won't have enough PCI-E ports, so maybe a 1000W Corsair with 6 ports.

A Corsair RM1000x has 6 x 8pin ports, so it could power two cards, but it won't have any 8pin cables for the CPU... Any advice here?

Simple  questions  why 750  a card?  yesterday card were selling  1080ti's as low as 590 a card on ebay


what power does that pro duo use  to do 900 sols for zec  400 watts?  

yesterdays sale on ebay

this one was 635 minus the ebucks  was 590

http://www.ebay.com/itm/GIGABYTE-GeForce-GTX-1080-Ti-DirectX-12-GV-N108TGAMING-OC-11GD-11GB-352-Bit-GDDR/292077280960?

this was about 640 after ebucks

[TheYankeesWin!]

so 590 for 650 sols  if you buy from newegg is

about 1.1 sols a dollar

and the pro duo is   1.55 sols a dollar


So power consumption and resale value   make the 1080ti close  but   maybe the pro duo at his price is a better deal.

Good points  on yesterday's ebay ebuck event

http://www.ebay.com/itm/GIGABYTE-GeForce-GTX-1080-DirectX-12-GV-N1080WF3OC-8GD-8GB-256-Bit-GDDR5X-PCI-Ex-/302026275977?


this was 500 - 40 for ebucks or 460  it does 540 sols  or 1.17 sols per 1 dollar

uses less power and has a better resale  but  the pro duo  at 1.55 sols wins  of course  the power use is an issue

as the nvidia's use less power.  So for resale  as  the coins come back to realty the 1080 will sell better on a resale.

For me I ordered another 1080 ti  comes next week  my cost was

650 - 51 in ebucks or 599

http://www.ebay.com/itm/332208363827?


There are coins that are good better then zec  that I am sure the nvidia has software to mine.

Skein is better then zec.    I have yet to see amd mine it.

For power, I'm guessing a 850W PSU should be enough for that setup, but it won't have enough PCI-E ports, so maybe a 1000W Corsair with 6 ports.

A Corsair RM1000x has 6 x 8pin ports, so it could power two cards, but it won't have any 8pin cables for the CPU... Any advice here?

Simple  questions  why 750  a card?  yesterday card were selling  1080ti's as low as 590 a card on ebay


what power does that pro duo use  to do 900 sols for zec  400 watts?  

yesterdays sale on ebay

this one was 635 minus the ebucks  was 590

http://www.ebay.com/itm/GIGABYTE-GeForce-GTX-1080-Ti-DirectX-12-GV-N108TGAMING-OC-11GD-11GB-352-Bit-GDDR/292077280960?

this was about 640 after ebucks

$750 is the cheapest in my country. If I look at ebay, I take a hit in currency exchange, as well as need to pay $65~$75 for shipping.

900sols for around 350~400 watts, is what people have reported. It doesn't beat the nvida cards in Hash per watt, but it wins in hash per dollar. On the specs at least. I guess I'll need to pick one up and test it myself...

so 590 for 650 sols  if you buy from newegg is

about 1.1 sols a dollar

and the pro duo is   1.55 sols a dollar

So power consumption and resale value   make the 1080ti close  but   maybe the pro duo at his price is a better deal.

Isnt pro duo also water cooled?

I think at stock 600sols and with OC settings maybe that pro duo seller touched 900sols with special setting.

Anyways, if using for a rig or two ok but would not want to use pro duo for ZEC mining farm because it will expensive to babysit.

Got my very first nvidia card after buying all RX 470/480s for the past year, 33 in total.
Zotac GTX 1070 mini, $350 from newegg.com.

I'm getting around 437 sols mining zcash with EWBF 0.3.3b 90% power, +200 core, +550 mem.
Can I get more? Please share some tricks and tips!
Also, which coin is more profitable to mine lately? I see Phil and others say skein, I've also heard DGB?
